What information on the Z-100 are you looking for.
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.)
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
