Subject: Basis 108/Apple II CP/M
I recently picked up a old system called a Basis 108. It apparently
is a West-German manufactured Apple II clone with a built in Z80.
This system will boot AppleDOS and Microsoft Softcard CP/M (CP/M
for the Apple II with a Z80 "softcard".)
The motherboard in this beast has built in serial/parallel connectors.
However, booting under Microsoft Softcard CP/M does not recognize the
existence of these ports. I assume that this version of CP/M is looking
for serial/parallel ports in the general Apple card slots (which are empty)
and not wherever in memory the built-in ports are located. The only
solution I can come up with is to either A) find a Basis-specific CP/M
boot disk or B) to come up with some schematics and try and hack the
Microsoft CP/M that I have.
So, has anyone ever seen or heard of this machine? Do you have a boot
disk or schematics, or know where I can get them? Any other general clues?
While this system will run some Apple II software, it seems much more
well suited to running CP/M.

Also, I have a real Apple II with a Z80 card that I am planning to use
to run CP/M (this system works fine - serial and parallel ports all
work.) Does anyone have any general advice about this type of system?
For people who want to get mess around with CP/M hacking, the AppleII/Z80
combo seems like a very cheap system. I've seen Apples priced as low
as $25-$50, and Z80 cards as low as $3-$10.
