my mini a1200

jimbob005 · 19 July 2008, 22:37

hi all i started talking about this in my other thread but i think it needs its own one .
So heres my a1200 in an a600 case every thing is working and running well

heres the pics

jimbob005 · 19 July 2008, 22:39

and some more

jimbob005 · 19 July 2008, 22:47

as you can see the board was a bit to big and needed a trim to fit. then the fun began we working the to ports but it can be done. and now iv put an dvd/rom in and a 2.5" 4gb hd it like a holiday suitcase to close but its all in there.

so now i have an a600 running 020@14mhz, 2mb chip ram, aga, ks 3.0, 4gb hdd (will go cf when adapter comes), dvd/rom

next job is upgrade card zetr0 has some ideas on this just waiting to see what comes up and what i can fit in 030 be nice

thanks for looking
james

any one wants any info on this just post and i will help

Graham Humphrey · 19 July 2008, 22:48

That looks really good, great work.

rkauer · 19 July 2008, 22:50

Where is Zetr0? Why he isn't here drooling?

jimbob005 · 19 July 2008, 22:54

he has as i said iv all ready posted about this but in another thread and on amibay. But it needs its own thread on here. so ppl can see the hard work iv put into the and the long hours soldering and working out and help from paul over in the wirral. this is on the rev 2b board

Really nice work!

I would like to make one myself if only it was possible to run turbo card.

Maybe not a turbo card. I'm uncertain if a memory expansion can be installed...

Anyway, a 1/2/4Mb SRAM card can be connected to the PCMCIA...

jimbob005 · 20 July 2008, 00:05

trying to get an 030 in there at the moment

Leffmann · 20 July 2008, 00:31

Really neat looking machine! Doesn't it get a bit too warm with the DVD (running) and the HD crammed up in there?

I never used the PCMCIA myself but I think I've read the interface is only 16-bit so I have to ask, how does a RAM expansion there appear in the system and how does it perform? As slow or fast RAM or as a storage device?

mfilos · 20 July 2008, 01:18

Outstanding work you did there mate! Congratulations! Zetr0 will be thrilled

SRAM PCMCIA Memory card acts as Fast RAM but can act also as a Storage device via PrepCard utility.
AFAIK it's slower than accelerator Fast RAM but since I have no experience I can't be sure of that.
I'm looking forward for the next exciting 030 if you ever do it! I thought of it in the past by doing reversed connector and attaching one via ribbon cable but the case+keyboard won't fit it (at least I guess so).

Well done my friend

Zetr0 · 20 July 2008, 02:22

@jimbob005

indeed... I am amazed at this, more so you had the dedication to see this all the way through, I have some ideas on helping you to get an accelerator in there, i have some sketched on paper, I shall draw them up on the computer a bit later today (Sunday) for you.

@all

Oh yes... I have seen this

Ooo a word to mention, about the SRAM memory addition to an A1200, this will actually slow the machine down around 10%

dword · 20 July 2008, 02:32

Thats superb Jimbob, I remember speaking to you on msn about it, man its funny comming from PCs and knowing a fair bit(about PCs) and seeing what you people are up to and lets be honest setting up PC mobos compared to amigas is childsplay , especially considering the PC boards well most modern ones dont need jumpers altered.

In a little while once I am more familiar with the amiga Im going to start getting some tech books on it , but I could never see myself managing to mod the things in the way you have, just dont know enough about electronics but seriously seeing projects like this makes me want to learn electronics to some degree at some point. (As mentioned on msn Im going through the indispensable PC hardware book and the only things I can say Im kinda lost at thus far is the electronics terminology)

Anyway great job Im glad it turned out alright! in fact very dam well

Nice Going

alphonsus · 20 July 2008, 03:03

That's beautiful!

Wish I had the balls to cut a mobo like that!

What did you use to make the cut?

Fingerlickin_B · 20 July 2008, 06:29

Wow, I had no idea it had gotten this far already...super-nice man!

PZ.

jimbob005 · 20 July 2008, 08:24

@alphonsus
i cut it with the dremal it wasn't to hard to do

@ all
thanks for the kind word . do you thinks this would sell well?? not thinking of selling it yet but was thinking in time to come?

thanks james

Charlie · 20 July 2008, 10:02

Ahhh, now there's some fine butchering!
Great work old chap.

Hmmm, getting an accelerator in there could be fun.
I guess one way would be to make up an adapter with two sockets & some ribbon cable in between...
...I wonder how far you can stretch expansion port signals before instability creeps in...
...also; where to get the edge connector sockets??

I wonder if something like this:

Might be adapted for the job

There's LinITX.com too for other such options.

Arnie · 20 July 2008, 13:34

Wow, great work Jimbob. It takes some bottle to butcher an A1200 board like that.

Yoto · 20 July 2008, 13:51

That's probably the baldest mod i´ve ever seen!!!

The thought of selling a Miggy makes me cry...and to sell such a custom job?

Just make sure the buyer is a keen Amiga freak!
