The Z-100 computer was a great machine for its time.
S-100 slots for things like A/D/A and I/O cards
Harddisk controller (20 MByte
ST-225 - never thought I could fill it!).
Reprogram the video for 640 x 512 interlaced monochrome (of course
you will need to create graphic character set).
Reprogram the Disk Drive for 96 TPI
Use a tether to connect a RAM chip for imaging (remove metal lid on
ceramic package and etch the protective layer - play with the DRAM
256K = 512x512 refresh rate.)
CPM
P-System
DOS
I have a copy of TT-04 rev 03 Zenith Technical Training Manual, which
is a great reference for 8088/86 programming.
Another great reference is the PUP (Programmers Utility Pack) 8088/86
programming.

Well I did get one for a song as Z-100 seems to
ring a bell,about 10 years
ago but I had to toss it since it came with no DOS with it. It
was a nice machine, but with no Internet to get a OS booted for it was useless.
Ben, that's a shame :-((( When I got mine from Joe Rigdon a
few years back it had all of the OS disks except for CP/M-85,
which Don Maslin (MHRIP) was kind enough to provide.
I partitioned the hard drive into thirds, and set it up for
dual-boot (ZDOS and CP/M-86).
Unfortunately, the version of CP/M-85 Don sent me does not
support a hard drive. I've never taken the time to patch it
for hard drive support, since I really like CP/M-86. If I
ever do, I'll install it on the third partition.
I made Teledisk images for all three of the Z-100 CP/M-86
disks, so if anyone out there needs 'em I'll be glad to share.
