Yes, I had noticed that it appeared to be made out of standard looking
parts, though the PSU was different than the XT's, as I have an extra XT PSU
here I was keeping around just in case I ever had a project, such as external
drives or such, that needed one. I had forgotten how much the very early XT
keyboards left to be desired though!
The PSU is very similar electrically (although I think it's 114W, not
135W, or something). Mechanically it's very different.
If you want 640K without wasting a slot,
here's what to do :
Thanks for the info on the MOD! It likely won't be done anytime soon, but
it's a good thing to know about. About the only thing I plan on doing right
away is adding a serial port to it.
It's worth doing - 41256's are trivial to obtain (off old 286 memory
boards if nothing else!), and it takes about 5 minutes. I did it to my
portable the day I got it...
Since you seem rather knowledgable of the system, do you know why it won't
boot into CP/M-86 ver 1.1, but continues into the BASIC ROM after it checks
the drive?
No idea, I'm afraid. Does CP/M 86 run on an XT? (I beleive a few things
wouldn't) - the portable is really an XT (and not a PC) system.
