I treat the old girl to a nice modern case sticker.
IDE Fix Express adapter with jumpers moved to underside
The fly lead header has to go too for my DVD drive to fit....
Thats much better
I decided to take off the clock port expander connector as well on the IDE Fix Express, its just generally in the way and I wont ever use it.
I cut off the sides of my keyboard to allow the LED board free movement. Its annoying having to feed that wire in and out when one removes the top
Soldered Clockport expander fly lead directly to the underside of the Rom
Fed the fly lead cable through one of the old HDD caddy holder holes :)
Bye bye old C306.... (this one smelt very fishy)
And welcome to the new C306. I replaced all my Electrolytics....
More replaced Caps
1D4 timing fix. Removed E123C and E125C.
Made a boo boo, ripped one of the Caps tracks off, quite a nasty spot as well....
... but fixed that by running a wire :)
Power cable for extra juice at the floppy header for BVPPC. Fed the wire through another HDD mount hole
Sticky back pads and a bit of insulation tape for good measure
Here it is coming through the other end... I put an extra connector on for floppy and added a 12V fan cable too. I plan to add a fan speed controller circuit that can control 2 fans from one 12V plug
Ready for connecting to Delfina Soundcard
The 10 pin connector on the indivision collides with the BVision, so I took it off and soldered the wires directly to the board.
Hand wiring the IDE cable that will run from Mainboard to IDE Fix Express input.
That was time consuming! I enjoyed myself though :D
Clamping the IDE connector together.
And here it is installed! I've made the cable run around the Indivision to reduce heat on top of it. I've now mounted the IDE Fix Express permanently on top of the Indivision with industrial double sided sticky pads. You can also see the clock port expander mounted on a riser. this is ready for the BVision (which is not working at the moment BTW.. boo hoo)
My BPPC is running at 66MHz now with some (temporary) 32MB simms. I need to do a bit of hacking to the Heatsink clip and the Floppy bracket to allow my 128MB simms fit.
And now with my DVD/HDD mounted.
Its a bit of a tight fit, but the cables all run nicely now they are split.
The BPPC heatsink clip, cut down to allow my other 128MB SIMM to fit...
Cut off the metal flaps that simply get in the way of the BVPPC and Memory SIMMs on the BPPC.
here you can see the BPPC heatsink clip cut down a little.
Now the chunky SIMM can clip in properly! :D
I cut my Floppy Drive bracket to allow installing my hefty 128MB SIMMs
Here's my cut down floppy bracket installed.
Now this is a REAL beast! ROAR! :D
Oh! Just a random shot of my new 11dB case fans that arrived today. These will be placed along the top grill of the casing inside.
256MB baby! YEAH! the SIMMS work at 66MHz!
A little shot of my hardware in whichamiga.
Cable added for powering my DVD drive. the juice wasn't good enough coming from the IDE cable once the BPPC was in, so decided to route a more robust power cable.
There we go :)
The RF modulator is out! making way for an exhaust fan..
R.I.P RF, you served me well in the 90's old pal
20mm Exhaust fan. Temporary mounting. Still need to cut the plastic casing....
Cut the RF hole in the metal shield a little more to house a rear exhaust fan.
heres the rough cut of the case
After some careful filing.
And there it is finished. This Exhaust fan works wonders on the HDD and Indivision. The underside of the 1200 used to get quite warm, now its barely warm at all.
Here is the beginnings of my custom rear expansion board. It will eventually house an automatic VGA switching circuit and the square hole will have an Ethernet port poking out for my USB to Ethernet adapter.
A quick check that it fits ok
I've added an Ethernet port
Heres my stripped USB ethernet adapter ready for mounting.
Adding some legs
To place here :)
Added a USB header and cable
Made a hole for the "official" case screw
Added a screw and nut
This is how it looks from the back
Here's my USB to CF adapter with USB plug removed
Soldered in some USB cable
High bond double sided sticky tape ready to hold in place my CF adapter
Not finished yet though...
Bit of hot glue to finish off :)
Marking out the hole for the CF
The first rough cut
Patience with the file and then its finished
And with the guts back in :)
Fits nice and snug
Easy enough to use the PCMCIA also
I made a USB board. Just a simple affair to hold the USB ports a little more sturdy when I mount them in the casing soon
Underneath, nothing special
The USB ports will protrude a little and hopefully be flush with the sides of the outer part of the casing when I cut the hole
More USB cables made for the External sockets
Ready to cut
Rough cut with dremel and a drill
And that filing again :)
Quick test to see if they fit. took a few tweaks but finally got there
I'm quite proud
Its a tight fit but two cables fit. I should have maybe made them a bit further apart. Might change this later
Run the wires
Fits snugly under the floppy rear
The startings of my Sound output from Delfina. This will go in place of the original phonos
Delfina gets a makeover. took off all the sticking up connectors. Need to slim her down if she is going to fit under my keyboard.
The connectors are simply run on wires
This Cap had to be turned 90 deg to allow the keyboard to rest over properly
Off with the IDC headers!
Insulating plastic to stop shorts on the mainboard
I decided to take off the clock port too. Its too high. This next part was quite bum rumbly...
Taking off the header without ruining the small caps underneath. It was ok.
Wire in the cable being extra sure on orientation!
Its very close!
There we go. ready to install
Rough check before putting DVD drive back in. seems ok
Wow just fits! Very snug!
next to the BPPC
Looking carefully under the keyboard. plenty of room! NOT!
And with the keyboard in there is 2 mm to spare to give the delfina a small amount of breathing space! :D
So here we see the Subway USB controller being nestled across the back of the machine. I stuck it down with double sided industrial sticking padded tape
Wiring up the USB cables from the 2 external USB ports and the internal CF reader and Ethernet port.
I put my broken BVision in just to see how the space was. The heatsinks on the BVision are just resting, not stuck down yet.
All wires are plugged in now
Zoomed out shot to show the how everything is sitting together
And from the front
Making the trapdoor vent, rough cut with dremel
Needs a bit of filing
DING! majik :)
Cut out a piece of aluminium mesh and slotted it into the hole. very small dabs of super glue on each resting point hold it in + a bit of pressure from the mesh itself
Now the Beast can breathe properly! :)
theres the PPC Heatsink
And the 060. You can't see so well here, but there is enough space to just fit a 6mm heatsink on. I think I will find a nice one for him.
Now the BVision is out again so I can prepare to power up.
Split the Floppy cable and tucked the wires under the Subway. ready for the case fans.
Here they are! again mounted with super ace sticking pads (and later I added a bit of hot glue to be sure)
All wired up and ready to go. The fans will mainly be pouring air on the BVision at some point, but for now they offer a boost in cool air for the other components too.
Powered her up and she boots fine with everything in (except BVPPC).
So there she is all assembled. Just need a working BVision and to make a video switcher circuit then she is done!
My Daughter has a bash on the keyboard. I tried to do a quick check of some things under the lid whilst she was on my knee, not a good idea, so put the top back on and let her "type" :)
Subway is detected :)
My CF card reader and Ethernet adapter both popped up automatically
Testing the USB ports with a Memory Stick (8GB)
Yep, it appears :)
First port, ok :)
And second one, Both ports work, nice :)
Heres the USB key popping up on the Workbench
CF card inserted in reader...
Pops up instantly, and when I say instant I mean the split second its plugged in. Very nice!
Heres one of my PSX joypad adapters running with a Dualshock 2
My BVision is fixed, here is the early boot screen showing through BV
Hiding under the nest of wires is the BVision
The Boot Screen looks a bit messed up through the BV, this is normal
Another shot of the BV
Zoomed out shot of the system
Open with the top fans showing
And back with the Indivision output to show it still works with the BV in as well
I had to add a +5V feed directly to the HDD and the power coming from the IDE Fix Express was dropping off with the BV now in drawing more juice.
Nice Heatsinks on the BV
And a 3mm one on the 060
A POWER the most awesome PSU ever! This beaut powers my whole system with no sweat. 7A on 5V :)
Next to the old beastly ATX unit.
The ratings say it all
Thats right, that little brick powers everything!
I spaced out my USB ports a bit so that chunky USB devices fit better.
I decided to neaten up the Delfina outputs.
Wired in some IDE cable
From the top.
And looped into the Delfina. I made some labels too so I don't get mixed up.
Here it is sat in my A1200, just enough space to squeeze in the CDDA cable connectors.
Heres the start of my Auto Monitor Switcher, its an LT1675. I can feed 2 seperate RGB signals into it and on pin 10 I can switch between the two inputs with either logic 1 or 0.
through the scope so I can get soldering.
I use some 80 way IDE ribbon cable as it seems the correct pitch.
All soldered up!
This is so you can see how small it is.
Finished, ready to plop into my project board.
Here it is with just the two connections for BV and Indi. I made new connection on the Indi with a grey plug.
And just for tests I wired the original VGA plug to a 10 pin header.
I can easily check the signal if need be.
And here is a newly made ribbon cable with black plugs for the BV. Its important that I don't mix them up as the pinouts for both are different. I reverse polarized the connectors so the notches are on opposite sides. Now there is no danger of getting mixed up.
Heres how the cables look going under the Floppy drive. I purposely made a kink in the BV wire so its not touching the heatsink.
Tight squeeze! its about 1mm space. the cables run along with the mouse connector.
Panned out in all its glory :)
Top of my AVS all finished now. The other chip is a CD4053 which controls the Sync signals along with the RGB from the LT1675. I have a Voltage inverter on there to providing -5V.
I labelled the connections just to be sure. The power source is 5V. the lone pin is for the switching signal from the parallel port (Pin 13, select) The software detecting when CGX starts will change the logic level to a 1. It defaults at 0 for Native Output.
Here is my AVS all wired up and finished!
Here it is in my A1200.
Both VGA outputs in, the 5V power and the switching signal.
This is the switching signal wire soldered internally to pin 13 of the Parallel port.
And a zoomed out shot of it all in!
I got some EPROMS to make my own 3.9 Roms :)
I decided to mod my Clock port expander..... Take the connector off....
And put in some flexible cable.
So I can possibly add heatsinks to the BV RAM.
I've added a small pin to +5V on my Delfina because after I put in my BV its been a little touchy, sometimes it doesn't activate on cold boot or even warm resets.
Here's the +5V wire coming from the floppy port. No problems now.
I've made a simple mixer circuit for Native audio and Delfina. This is so that I can use native software without the need for the Delfina mixer to be loaded. If only the Delfina had a native pass thru, but never mind, this solves the problem. Its basically 10K ohm resistance on each line which I can adjust volume on each channel if need be as I used Pots instead of resistors.
Wiring it in, I've also added some extra earth lines to connect the mixer to the metal sheilding of the A1200...
Here it is sitting loosely in place to test.
And now if you look carefully i've soldered the little "hooks" I made to the Metal sheilding at the back. This holds it solidly (and much more so than hotglue I had on the other cludge)
Audio connectors from the back, lined up quite well I think! :)
Added a +5v jump lead to the Subway, this has made it stable after installing the BV. It would sometimes not initialise at boot up, now its ok :)
Close up, its connected to "Pin 2" of the Subway.
A rough Diagram to show my audio mixer.
Here's my homemade PWM Fan controller for the case fans, it makes them run alot quieter. I also have a thermistor attached to it for automatically increasing fan speed when its needed.
Close shot, Its using a 555 timer.
Here it is in the case next to my AVS.
I put the thermistor over the middle of the Permedia 2 chip on the BV
I've added a Mic and Aux port to the external case.
From the inside
Connected to the Delfina adapter I made
I cut delves in the plastic and run the wires here
Showing a jack plugged in
With the lid on :)
I rolled my own 3.9 ROMS :) No more rebooting on cold boot!
Look at the menu bar to see Kickstart 3.9.
I've added a very discreet toggle switch to manually override my Auto Video Switcher. Good for when performing OS installs with no switching software loaded. Now I can switch to RTG if need be.
I found a nice new fan for my PPC! Here's the BPPC with the old heat sink taken away and the new fan with heatsink built in resting on top.
Looks like it will fit nice!
from the other side, all looks good.
Drilled two holes in the sides here to allow a small amount of air to flow over the two regulators on the BPPC.
And now onto mounting some pillars. Here i'm making new holes and threadding them. I've already mounted two small nylon screws and nuts. The nuts will be super glued down to the BPPC board to allow mounting.
Here's the standoff posts, they need cutting down a tad :)
Cut and filed down to be level with the nuts + 0.5mm for leeway
Here's the new fan next to the old one.
I rested the heatsink onto the board with the screws and nuts in place, then carefully put super glue on the nuts, then unscrewed the screws to leave the nuts in place. I added more glue around the edge, then put a hair dryer over the glue gently, this makes it dry alot harder.
Arctic silver compound! :)
Applied to the PPC
Then a small 1mm thick copper plate placed over the top.
More arctic silver.
And the fan and heatsink combo put over that, then lightly screwed down with the nylon screws.
It fits great. I had to fine tune the standoffs until they held the heatsink around 0.5mm above the nuts. If you look carefully you can see a small gap between nut and heatsink. This allows for a small amount of tightening.
I added some heat shrink to the Custom made Oscillator, just to make it look nice and its more insulated than with the scrappy tape I put on it before this.
You can see the Oscillator in place and also the fan heatsink combo.... but can you notice the side vent? yes, thats going to pour airflow over the oscillators and the 060 :)
But I need to put heatsinks on this controller....
And these two ICs. They both originally sat under the PPC heatsink and enjoyed a dash of air from the old fan. now they get nothing and hit around 66 Deg C!
Over shot just to show how it looks. I ended up taking the small black padding off the fan as it wasn't necessary. I'd put them on to avoid any vibrations on the trapdoor, but they just made it bulge out unecessarily.
So what shall I put on this?
These Copper VGA sinks, very nice they are.
There we go :) Self sticking with thermal pads.
With the trapdoor cover on. I am happy I managed to make a solution that kept within the trapdoor. Now after 1 Hour on, The temps are, 52 Deg C on PPC (was 55), 50 Deg C on 060 (was 62) the controller hits 54 Deg C and the Regulator IC's hit 58 Deg C. Overall alot more evened out. I'm most happy that now my 060 is running MUCH cooler :) The fan is a bit quieter than the old one too so that's a bonus!
heatsinks added to some of the hot IC's on the BPPC.
I put a trimmer on the fan controller, now I can adjust the sensitivity of the thermistor :)
Original PSU.... its not so powerful. I need to retrofit my APOWER into this unit.
Inside with original supply.
I need to cut these wires out
Board removed and only the original wires left.
Extending the sheild wire to earth.
Made a small note to know the voltage on each wire (note that this is different on some PSUs)
Need to cut down the posts a little.
and trim out the sides a bit.
Hot glued a big 12V fan under the top casing.
Heres the APOWER taken out of its casing.
Wiring on the Power cable.
And the switch.
Earth stud added.
Rough fitting into the case.
I shaved a small part of the screw hole in the APOWER board to allow the use of the original mount.
on this side it fits nice as it is :)
Now for the cable to the Amiga. Adding a nice terminal block for easy mounting. I used one of the original screw mounts to hold it down.
With the APOWER in and wiring up the DC voltage lines to the other side of the terminal block.
Wired in the fan to 12V.
Zoomed out to see it all.
I added a PWM fan controller as the noise from the fan was too loud, now its very quiet :)
All back together again, notice how it looks totally original from the outside :)
I bought a Lyra II. I'm gonna try and mount it in my A1200 somehow!
Close up of the Lyra II, the jumper along the top switches between PC and Amiga Keyboard. I'll add a toggle switch to that :)
Got myself a 320GB drive, i'll attempt to put this in the Amiga and replace the 80GB drive.
So there is the keyboard controller the Lyra has to sit on
And i'm gonna take out the Video phono plug and place the PS2 plug there instead.
Hmmm... this needs modding!
EEK! Best not remove the connector then :D
Didn't say anything about soldering wires underneath voiding warranties did it?
The level of destruction needed to take one Video phono connector off.
There it is!
Out you pop me lad!
This is just an experimental 12V to 5V mod I made for the DVD drive. It didn't work so well, the drive wouldn't spin up a disk on a warm reset properly so I eneded up taking it out after the Lyra II mod.
There is the Lyra in place.
But I realised I have to move the wires as they get in the way of the IDE Fix Express.
bit of tape to insulate.
and some tape over the mainboard where the PS2 connector will be.
On goes the Indi and IDE Fix
Took the board out again to solder on the PS2 connector. same methods I used to hold on the Audio mixer, basically soldered the body of the connector to the metal sheilding.
There we go, nice and flush. I had to heat and move the connector a few times to get it in the right place.
Testing the fitting with an Amiga keyboard (well a CDTV keyboard with a CD32 Adapter).
And with a PS2 PC keyboard, both plug in snugly.
Sliding the board back in... ooo, it JUST fits!
1 mm to spare underneath.
roughly drawing where the wires go on the PS2 connector.
And soldered on.
Here's the switch I have connected to the keyboard selector jumper. Shorted = PC keyboard, open = Amiga Keyboard.
from underneath the lip.
Another one of those wide shots of all the shit in my A1200, how it still works baffles me!
The Lyra II just nesting quite tightly in there!
With the top on.
Added some stickers to be sure, don't want to forget and plug the wrong type of KB in!
Did the same for my manual override switch on my Auto Video Switcher. Not as dangerous, but still good to have :)
The keyboard works! :)
CDTV Keyboard with a CD32 (A4000) adapter :)
Added a Yellow LED to my USB NIC adapter so I can see when its active.
Small hole and its just squeezed in (2.5mm) The LED is a flat top so its flush with the casing.
I also decided to add one to the DVD drive.
Here's the USB NIC LED flashing away as it works.
And the DVD LED working.
Just a diagram to show how internal native Sound output is rigged to the Phono sockets. This allows mono sound to pass when R is not connected.
The battery on my BPPC started to fail at 2.5V it wasn't holding date and time correctly. So I decided to replace it and make it easier to replace in future.
Off comes the old one...
And I use the hole from the old fan placement to wedge a standard coin battery socket.
From the otherside wired into the old points (+ is purple). I added some small dabs of super glue to select points just to keep it steady.
Here it is the other side. Ignore the CR2032, I need a rechargeable type (VL or ML2032). this is just to show how it looks :)
Time to replace the caps on my BVPPC. 3 here...
4 on top.
Sorted. 5 106 caps and 2 107 caps to do BV.
Adding 2 fans to BV and ditching my case fans. this is so I can run the machine with the lid off for longer than 10 mins, without fear of frying the Permedia 2 chip.
fixed on with 2mm screws and a small dollop or super glue at the base of each sat in the heat sink. Cut and routed both wires to a header.
I took off the express mode jumpers as sometimes the machine would boot with an exclaimer saying that express mode was off. I suspected the jumpers, and since I wont ever run in non-express I decided to hard solder. No problems now :) I also cleaned up the board a bit and applied some lacquer.
I got a new PLCC socket for my Indivision from Cosoms. Sometimes my system would have no screen from cold boot. This better quality connector should hopefully solve this problem.
Taken off the plastic bits with a dremel
here's the old socket (in all its sanded down from new glory)
Out ya come old chap
Added a spacer to make the Indi sit level once in the miggy
The new socket is on now. You can see how the spacer helps here. (The Ide Fix express is on top).
Finished off with a bit of a clean and laquer :)
Now to replace the caps on BPPC.
Off they come on one side.
And new ones added.
Fan and heatsink off PPC some are under that. But there is also one under the oscillators.
Oscillators off too. Here's a zoom out view. (Notice I have the correct ML2032 Rechargeable Batt now too)
If you look closely, I have a job with the two caps near the glued on nuts. they are half covered in glue :D
No probs, here's most of the other side done....
But I looked between the pins of the 060 and saw what looked like more caps, after cosmos confirmed there are 3 more there, I took off the 060 and lo behold!
New ones in :) As you can see, Oscillators, heatsinks and fan are back on. all in all for non SCSI its 33 106 caps and 5 107 caps. you need 5 more 106 for SCSI.
I've re-routed the power lines under the board. No need for the top mounted wires as i've finished the tests I needed to perform with them connected and disconnected.
I added a connector to the CF adapter. This just makes things a bit easier when working in the machine.
I hard soldered the Mouse port to the board. This gives more room for the VGA cables to go under the floppy without getting too squashed.
I removed the connector on my Lyra! OOPS! :O
But put a new connector on top, much neater. And easier when having to dismantle.
Here it is connected up.
My new peripheral power cable! :) floppy, fans, VGA switcher and 2x +5V for Subway and Delfina.
A little bit neater inside now the big power cable is out. Also more room for the BV fans.
Much needed fan grill, looks nice now :)
I changed my Auto VGA switch to include a manual AGA feature. I've discovered that some programs don't auto switch to AGA from RTG as the RTG screen gets left open! so for them few programs (mainly Mega Demos) I can manually flick over to AGA. All I did was basically add an on off on toggle and lead +5V for AGA. Red is signal (when open in middle position its ground so stays RTG), black is +5v (for AGA) and yellow is to the parallel port pin 13 for auto control.
Slimmed down my PWM controller.
And placed it on my keyboard! Why? well under the floppy was awkward to access, and it seemed to interfere a little with the VGA output (the 555 timer was directly under the cables) so the screen would shimmer sometimes.
I put a hole in the trapdoor. The fan on the PPC chip was sometimes scraping on it and making a nasty noise!
Nice bit of room for the fan now :)
Decided to take off the PLCC socket and exchange for a better quality one.
Take off the posts to allow snug fit
Old one off and new one ready to go on
I shaved some of the plastic where it meets the PCB too, this gives a ½mm extra space for the DVD drive sitting ontop of the chip when installed in my machine
Coated and finished
Here's some nice 29F800 custom flash chips from Poland (thanks stachu100 helping me get these). I've labelled them so I don't get confused when programming etc.
I put new sockets into the Mainboard so the new Flash chips will fit better. also labelled them
Setup in the good old Willem
The Willem software
First programming attempt is a success!
Little labels just incase :)
And my desktop :)
I've added direct power lines to IDE Fix express. This helps with stability.
I added some screening over the Indivision cable. This eliminated some noise I was getting on AGA Output
And here's the BVision cable resting over it. Just enough space for the floppy drive to fit
My Flash Kicks holding 3.9 and 3.1 Kickstarts. Selectable by a switch connected to pin 1 of each Chip.
The switch selects 3.9 with HDD powered or 3.1 with HDD turned off (so my A1200 can go into vanilla mode) If I hold key "2" on bootup I can disable my PPC also. This is so I can play Floppy games or Demos that only like 020 2MB chip.
The HDD power cable
Newly adapted power connector for HDD. It will turn off when I select 3.1 rom Switch
Here it is with 3.1 Active
And here's 3.9 :) (I just unplugged the HDD to show this screen)
