My A1200

[8bitbubsy]

Time to show the world my boring little A1200! :laughing
Sorry for bad pictures, I only have my mobile phone for taking pictures! :crying

The A1200 (1GB CF + Indivision AGA 1200) opened, in glory and blurriness:

The floppy drive (and floppy drive connector on mobo) is modded by me so that it acts like a normal Amiga floppy drive - brand new and even boots the Sanity demos!
The black thick wire under the floppy drive is for connecting the VGA connector's metal to the Amiga's internal ground.
(I need a 4GB CF and something to isolate the CF adapter pins...)



It's indeed a rev 2B mobo (new old stock from Amigakit):

Look, it's non-polarized capacitors! (22µF 100v, glued with hot glue and not glued to the metal shielding for practical reasons)

(Don't get alarmed, the capacitor pins do NOT short onto the serial connector's ground!)



Here's my VGA bracket mount:

My lovely Microbotics M1230 XA (68030 50MHz, 32MB RAM):

The electrolytic caps are changed for new ones, and the CPU/FPU crystals are directly soldered for more stability:

(Again, don't worry, there's no short from the yellow cap pins to the crystals - I've checked that)



It has got an old MC68030RC50B in it that gets too warm, but I've ordered a new MC68030RC50C and an MC68882RC40A FPU for it!

More pictures to come! Especially when I get my new CPU and FPU (+ 64 MB RAM)

@8BitBubsy

thats shaping up to be quite a tasty little A1200 indeed!

so whats happened to your Apollo 040?

It's barely alive... It was just as you said: Don't play too much with it, it'll die :(
I think it kind of works (a lot of bridge wires), but I need a new 040 as the one I had is broken now.
I tried another 040 earlier and it didn't want to accept it.

I don't want to use it because:
1) It doesn't fit with the trapdoor on
2) It needs a heatsink (or the rare "late mask" 040)

It could be good for a tower, though.

Nice

as u have a 2b Mobo are you going to solder a ps2 or 5pin din conector to it so that you can use an A2000 or A4000 keyboard ?? Ive just done that to my 2b Mobo and it works a treat. Pic will be sorted some time this week I hope

Bubsy, what are those capacitors? For audio? Why are they so BIG? :D

Yes, they are for the audio - there's supposed to be non-polarized/bi-directional capacitors in the audio out circuit, not polarized as Commodore used (to save money :mad).
I have no idea why they are so big, I guess it's because of 100v rating + some more mystic stuff -- I couldn't find any smaller. :laughing

They add nice colour to the board. Stick some LED's under the vents and those red beasts will shine through :) The yellow socket looks awesome under blue LED's.

Very nice and for a camera phone those pictures are brilliant.

The keyboard connector can be soldered direct to a 2B board? Do you have more information on this??

[Anemos]

Nice, clear and no so terrible mods,is keeping the classic style..
i like it.
congrats ;)

Look at this post from good friend Zetr0. (http://eab.abime.net/showpost.php?p=452708&postcount=16)

Ignore the A500 wire up: you need only the motherboard pinout and a female PS/2 (for A4000/CD32/CDTV keyboards) or normal DIN for all others.
