I have a fine old Stag PPZ modular EPROM programmer:
It takes plug-in EPROM (model Zm2000) and PAL (Zm2200) modules, called
Z-modules by Stag. I've recently acquired a new module, Zm3000, which
looks like a more recent EPROM module. The chips in the Zm3000 are
date coded in 1993, whereas the Zm2000 is nearer 1988. The PPZ main
unit contains a 6809 CPU and a small CRT display.
Does anyone know anything about this system? What about other Z-module
types? In particular, should the Zm3000 work with the PPZ, because I
currently get an error message "Incorrect Mainframe"?
Thanks in advance for any clues! (Virtually all I get from Google is a
link back to my own web page!)
