Subject: Z-system and the Epson PX-8
Last year when I bought my ZCPR3 and ZCOM for my desktop micro I tried it
out on my PX8 as an interesting exercise - it crashed the system. I have
decided that this is probably due to the VBIOS which only provides the usual
BIOS jump table and the PX-8 has an extended set of BIOS functions. With
only a 128K RAM disk it did not really matter, so I terminated the experiment
after deciding that I could always patch the VBIOS and move one of the other
segments if it was actually needed. My curiosity has been re-awakened by a
TCAP file which includes one for the PX-8. So the question is this - did
others patch the VBIOS? Have I mistakenly diagnosed the problem? I don't
think you can do a manual install on the PX-8 as the CP/M is held in a ROM -
or did some clever person do a manual install and blow a new ROM? Does anyone
out there know? Thanks in anticipation.
