I have two of the PPZs AND (drum roll, please!) THE MANUAL! I have two
different type plug ins. One for standard EPROMs and one for BiPolar PROMs
(and maybe PALs) but I don't remember their model numbers but 2000 and 2200
sound right. It sounds like your 3000 module is made for another machine
and not for the PPZ. I'll have to retrieve the manual from the warehouse
but I don't think it lists the various modules that go with the PPZ.

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!)
