Remember there's no hard disk - and in fact IBM state that the portable
doesn't support a hard disk - which may account for the lower power PSU.
Mind you, I've seen 5155's where one of the floppy drives had been
replaced by a 1/2 height winchester, with a short-length controller card
in one of the expansion slots. It seemed OK, but then such drives took a
lot less power than the original full-height 10Mbyte unit.
The PSU is very similar electrically (although I
think it's 114W, not
135W, or something). Mechanically it's very different.
That's certainly not much to be running everything including the monitor
off of. One would think that with the addition of that CRT that they'd have
upped the power a little. 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...
What about the other chip you said needed to be put in...how hard is it to
locate? It doesn't sound like the process would be terribly hard. Jeff jeffh(a)eleventh.com
