Putting an A1200 board in an A1000...

[Kristian95]

Not really a hardware problem, more like an idea that has been festering in my brain lately
My very first miggy was an A1000, and I really love the A1000 case with the keyboard sliding underneath it and all, my favourite desktop case of all times for sure!!
So I was wondering, would it be possible (and not too hard) to fit an A1200 motherboard in an A1000 case and use the A1000 keyboard and floppydrive with the 1200 mb ??
This far it's just a curious question.... hope you guys don't consider it being a blasphemic one too hehehehe

I do love Hackery....

although this is crazy, i love it too....

now, to take partake in your will need to make sure theres enough width for the mobo, there should be..... just.... but you will have to remove the PSU. fear not, we can replace that with a Pico 120watt PSU or better (or remain with the brick psu out the back.

you will have to make a backplane / panel for the a1200 mobo.. perhaps lead some ports for mouse / joystick to the side or front of the case.

The mountings for the FFD may need to be changed, not to sure on that, and depending on what motherboard revision you may need a keyboard interface.

(rev 2b a1200 has a header you can populate and use like an a500)


tools would be numerious and what you are used to working with, but i would recommend a scroll saw, drill press and or rotary tool (the modders swiss army knife) so HB pencils for marking, 100 grit imperial sanding blocks, wet and dry 800 - 1000 grit sand for final detailing, i would suggest some acrylic under coat.

This sounds like a really intresting project !!! - perhaps it would be possible to add some kind of bus board too? making it a very expandable project? I have never seen a A1000 up close and personal so its just an idea as I dont know if it would fit lol.

[Fingerlickin_B]

Not tall enough to fit Zorro or PCI cards (re. busboard), but this sounds like a cool project...and I mean VERY COOL!

Progress pics as you go please!

if you were willing to purchase or make your own right angled Z2 ports then you could deffiantely get a gfx card in there, something like a CV6432Mk2 or better.

Arguably if you design your own and then have www.futurelec.com build it for you, you could have a left and right angled zorro ports, allowing you to get fast scsi and rtg gfx....

but again.... its all limited to imagination.

[Kristian95]

hehehe this far it is only a dream project... I have never modded any Amiga ever... yet and I'm currently finishing of a moving between continents and looking for a new job, so my finances unfortunately can't justify buying more miggys at the moment
But who knows, maybe I inspired someone to make this "A1100" ??

[Zetr0]

hmmm if you added 1000, and 1200 it would be an A2200 coolies

[Kristian95]

hehehe I figured that the 1200 and the 1000 share space hence you add them and divide by 2 hence A1100

[cosmicfrog]

or how`s about A1020

[Kristian95]

btw if I do end up getting hold of an old A1000 and it is badly yellowed, including the keyboard, is it possible to replace the keys on the keyboard with keys from say a new A1200 keyboard??
Also, what is the colour of an A1000, in case it will need a respray??
Btw, for respraying it is: rinse case, sand case (??), prime case (what kind of primer), sand case (??) and paint case (what kind of paint and what is the Amiga-colour named??)

Going on from this.... I have just bought (but not collected yet) a mint A1500 (mouse, keyboard, discs, manuals, original box 6MB RAM, an unknown processor board with a 25Mhz 040 in it and a 68882, some unknown at present SCSI cards, no other drives than the 2 FDDs) I have some bits from an old Mac lying around so I can give it a HDD and a CDROM. I was thinking about how to ramp it up a bit and was wondering if I should gut it and stick my A1200 motherboard in it and by a Zorro bus board. Can / should I do this, or should I buy a GFX card and a faster CPU for the 1500 and leave the A1200 alone? For that matter, does anyone know if the "empty" processor slot that comes on A1500 / A2000 motherboards is PGA or PLCC and what can I just stick in there?

[Zetr0]

an A1500 is infact a re-badged A2000

heres some more info

http://amiga.resource.cx/mod/a2000.html

personally i would not put an a1200 in there, and in truth i doubt theres enough room at any elevation to be honest.

I do love the A2000 its an awesome bit of kit.... well worth keeping IMHO

the unknown processor board is interesting, with the right bit of hackery, you may well be able to convert it to a 50mhz 060

there are two processor slots on the A1500/2000 motherboard, one is the Fast Slot that accelerators slot into, (like that 040@25mhz) and the 64pin DIP on the motherboard for the 68k moto.

[Zetr0]

if I had (and note this is me) an A1500/2000 i would keep it, get the best accelerator i could, lump on SCSI HDD/ROM and GFX card... prolly internal sound card and network card, perhaps even USB using the thylacine z2 card

i would prolly also use a tft/crt tuner box (theres some great ones on eBay) for around £35 that upscan and flicker fix the screen, combine this with a KVM switch with the gfx card and lump on a nice 22" LCD or 19" CRT sweet!

whdload heaven! music compo heaven and a great little developing box too

[Kristian95]

erhm back to my "paint job questions" can anyone elaborate / confirm on the method I describe ??

Clean in a bath of warm soapy water,
Dry COMPLETELY,
Sand lightly with fine paper (I use carbon paper as opposed to sand)

Prime with a low-medium build primer (plasic primer for plasic parts, metal primer for metal) if you can cover with a single coat that will be fine.
Make sure if you are spraying to the original colour that you use a light coloured primer (white)

Spray the parts with your desired colour, on the first coat pay special attention to hard to reach areas, keep the can nozzle at least a foot away from the surface you are spraying and make nice even side to side motions.

Repeat after each coat has dried until coverage is excellent (I find 3 coats is more than sufficient)

Finally after dry spray with a coat of clear laquer, this may result in the case looking a little more shiney than the original but will protect your new paintwork.

Items I have sprayed with this method (several A1200s and Laptops) are still looking good 5 or 6 years on.

Zetro, can you download your brain for me so I can get the "knowledge?"
Kristian95, sorry for hijacking. I have started a new post in prb.hardwaremods about my new purchase.

AFAIK, the A1000 is hard to get yellowed. All those I saw (3!) was white as snow (and no one pee in it ).

@rkauer:

The main units are usually really nice looking, it's mainly the keyboard case and keys that can yellow.... maybe they used better quality plastics on the original A1000 units ??

Nope!

Simply they don't used anti-flame (fire retardant) in the case! Those anti-flame chemicals are proud to yellow other Amiga's cases.

And back in that time, only titanium dioxide was used as "whitening agent", who don't tend to go yellow when exposed to sunlight. After that time, they add talc (yes, that thing spread in baby's backs) mixed with TiO2 for lowering the costs. Unfortunately, talc tending to yellow when exposed to sunlight, too.

[Kristian95]

can someone who has an A1200 help me out with the actual dimensions of the motherboard, 'cause I'm likely to get my hands on a nice looking A1000 one of these coming days *yay*
Also, what revision A1200 board would be the best (expecting to use the machine mainly for whdload) and would it be better with an accellerator card or just a memory expansion (this rig would mainly be used for older titles).
