Do they have a parts list somewhere on the Web?

That bad, huh? :)

For the 1520, for starters, I'd like to know how to get the darn thing
to work without a hard drive connected. And I'd like to know which hard
drives I can use with the thing, and how to get it to recognize the
drive. I'd also like to know what was available for the ROM sockets
located under the trapdoor above the keyboard.
Oh yeah, and while we're at it, what about the "external peripheral"
connector on the back. And the specs for the CMOS battery. And whether
I can still get battery packs for the machine, and how to recharge them.
Regarding the Compass, I'd like to know what the machine expects to talk
to via the GPIB connector, and how it does so (what commands it uses).
Also whether GRiD-OS, GRiDVT100, and GRiDWrite are in ROM, or on the
Bubble device (seems to be the latter for GRiDVT100 and GRiDWrite, but
I'm not sure about the OS). And I'd like to know what the pinouts for
the weird serial connector on the back.
