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. --Tony Addyman
