A plug in module for PALASM? What would give you that
idea?
Well, as I recall, that's what written on the module :-)
I've seen only
one place on a model 29 for anything to plug in, and that's the programming
site. (there are several different ones)
That's right, it's a huge plug-in module to go in the
programming site socket. It has another plug-in module on
top to accept the PALs that are being programmed.
The data was typically fed to the
Model 29 via a serial port, and in JEDEC form. The model 29 translated the
jedec file into whatever signals were needed to program the device.
As I have no manual, I can't tell how this thing was
supposed to work.
The last time I used a model 29 was in '85. They
were already pretty old
back then and wouldn't program the then new Altera parts and Lattice parts I
was using. That was later fixed, but too late for me. I bought a cheapie
that still works . . .
I've since acquired a Stag PPZ Universal Programmer.
6809-based machine with built-in CRT.
Is there a feature that plugs in the intelligence to
compile Palasm files
into the JEDEC? I'd be VERY surprised to learn that.
I'll have to pop up into the loft and fetch this thing down
for a closer look (info in this e-mail is from memory).
I'll post model numbers, etc, in case anybody can identify
the module and tell me I've got it all wrong :-)
