If it had the keyboard, at least, I'd be interested; the monitor I'm sure I could work around (there's ways of getting a VGA card to work, I'm sure) though I would miss seeing all the old 6300 modes.

Actually, ChuckG found out you can make a 1:1 6300-to-VGA adapter with only wires. It pumps out VGA-compatible signals (who knew?), so you get to see 640x400 after all. I don't remember where Chuck's post was, but here's the info: ftp://ftp.oldskool.org/pub/misc/Hardware/ATT/Documentation/video_converter_output_to_VGA.pdf

Well, it should be possible use a standard PS/2 or AT keyboard driving a small MCU to generate appropriate keycodes if the appropriate keyboard couldn't be located.

I thought it was possible to build an AT&T PC6300-to-normal-XT keyboard adapter? I know I've seen the schematics for one, posted many years ago on CompuServe.

In my experience even if you have an M24/6300 keyboard that isn't the end of the problem as they seem to suffer without fail from needing a new set of capacitive discs which are a pain to make anyway!

If the codes are similar to an PC XT keyboard, addition of a voltage regulator and the XTAT adapter board might just do the trick with perhaps a little tweaking and a PS/2 keyboard.

Those discs are easy to make. I turned out enough for a TRS-80 model 16 in about 30 minutes. The trick is to just twist the punch through the material, not drive it through.

Back in 2005, my wife & I were moving and I was faced with doing a little downsizing. Most of what I got rid of wasn't a big deal...but I had an AT&T 6300 that I parted with...wish I'd known there were folks interested in them. I didn't have the keyboard, etc, so it wasn't much good to me. The other thing I really regret was that plain old NEC CGA monitor...the one that said "Multisync" on the front. Yeah...I didn't know what I had.

Salvation Army store wouldn't take it...gave it all to Goodwill...shortly after that I heard from somewhere they Goodwill was no longer taking computer donations...they probably pitched all my donations in the dumpster and grumbled about it the whole time. I still get a sinking feeling every time I think about it...

Heavy sigh...

Wesley
