The PX-8 is a small laptop, kinda similar to the HX-20 or the m100/NEC/m10
crowd, but more in the same class as the NEC Starlet. It's a CP/M machine
with an 8(?) line flip-up display and built-in micro-cassette drive.

The Mac Portable is an odd critter. It seems it runs off the battery, and
the power supply is only there to charge the battery. I'm learning a lot
about them right now, in fact. My current idea is to make a doohickey that
will feed power in from an external power source to the battery contacts so
you don't need the regular power supply at all.
Basically, if you don't have a working battery (or something to fool the mac
portable into thinking you do) then it won't work. The battery is a 6v
lead-acid battery.

The PX-8 runs (iirc -- I only got mine on Wednesday and spent yesterday at a
funeral so I haven't played with it much) on AA batteries. It has no floppy
or hard drive, and the small LCD screen probably doesn't use much juice.
Hence, all you need power for is the RAM and CPU/electronics.
