IBM 5155 with modern parts?

[Wibox]

I purchased an IBM 5155 and I am humbled by its awesome monitor, monitor controls, and keyboard.

I'd like to use linux on it without X- just the usual cli tools- ssh and irssi mostly.
I realize linux isn't going to run on this ancient hardware, so I need to figure out how to replace the motherboard in this thing with having the monitor survive.

I know I'll need to also make modifications to the keyboard, replace the power supply, etc..

I'm not familiar with the old monitor technologies here so I need some help if anyone can give it.

The monitor is connected to an RF modulator which is then connected to a 4pin composite connector on the CGA video card. The video card (and this 4pin connector) is described here.

I'm not sure if CGA composite is the same as normal composite or not. If it is, could I just connect the composite output of a video card to the RF modulator?

A friend pointed me in the direction of the Wikipedia page for CGA which states that the composite output is in normal NTSC format.

So.... The pins for the monitor are:

    Pin 1 is +12V
    Pin 2 is not present
    Pin 3 is composite video
    Pin 4 is ground

I could use the +12V from the peripheral connector on a power supply

And then I'm guessing since it is NTSC that the composite out of any video card will work?

someone ban that **** already

 
I guess the spam post was deleted by the time I saw this so it looked like you were replying directly to me. I was so confused

Im not sure if an ATX mobo will fit inside one of those things, would be interesting to fit a small embedded board inside it though.

XT form factor is the same as Baby AT. So, you can get as late as a P4 in there, although I'd recommend something a bit... lower power... (Besides, P4 Baby AT boards aren't exactly common.)

Put a BIG fan in there if you go P4.  Like a GE turbine.

High CFM Delta fans.

you could go with a ITX board. an Atom cpu and board are dirt cheap and would run a text UI just fine and generate little heat. replace the original system board with a metal plate. mount the new system board to the plate with standoffs - leaving room to make connections to the IO ports. extend IO ports to the original slot covers. gut the original PSU case and drop in the internals of a modern PSU. you might also try to mount a floppy faceplate on a slot-load optical drive.

from the outside it would look stock.
