Oi, I thought it was funny. Hillarious, even. Sheesh, I
would pay real money for a few "programmers" on Tony's
level of competence...

OBclassiccmp:

I'm playing with various bits of hardware as time permits. If
anyone has info, please forward, it will help me re-reverse-engineer
the wheel...

(1) Osborne 1.

 - Keyboard is shorted internally. Screen reads "insert disk
   and press Enter" or whatever, then refreshes / redraws
   all the time. This stops when I unplug the keyboard. I
   think I know which two pins connect to the Enter key,
   when I short those two pins same thing happens. I'm
   suspecting the 8877 FDC chip.

   Does anyone have:
   -- Memory (I/O) map
   -- Schematic (ja sure :-)
   -- BIOS disassembly
   -- tips on fixing the keyboard?

(2) Apollo DN3000 and DN3500

 -- Looks like the monitor/BIOS rom for the 3000 was written
    in C. Anybody know anything more than this?

 -- Memory map?
 -- Schematics? (I kill myself, I know :-)

(3) WPC (checks, youch, well, the system is 10 years old, even
    though my Addams Family will only get there in 2002...)

    Bank switched 6809. Figured out the memory map and most
    of what I need to know of the ASIC from the MAME source.
    How *they* figured it out is anyone's guess, but there's
    a bunch of hackers worth admiring.

    -- Generic question... anyone else messing around with
       WPC? Or Sys80 for that matter? (Haunted House, for
       those who are still reading :-)

Seeya all
