I had offered before, and then someone posted they were
going to read them via the ROM monitor. Thought it was
all taken care of already... Oh well. My main problem
was that my PROM programmer only has the DIP socket,
but the PROM on the 425e is a PLCC type chip.
But, I do have some PLCC sockets I can wirewrap
up to make a converter... I know I have the pinouts for
both the DIP & PLCC types around here.. should be easy
Let me see what I can come up with... got a PROM the
other day that a friend wanted me to copy for him, so
I have to drag the programmer out anyways. I can also
run it through my disassembler and come up with a basic
disassembly of it (uncommented, of course) for someone
to play with.
