If you need any help with your PromICE, let me know. I worked with
the founder of Grammar Engine years ago, and I have used their
ROMulator and PromICEs extensively (we used to help them out back
when VMS support was relevant - they would bring their download
code over, and we'd compile it for them).
Theirs was the first EPROM emulator I worked with, and I have to
say the experience was fanstastic. Our first target was a VAXBI
COMBOARD - with EPROMs, we'd have to shut down the VAX and remove
the board *plus* all the usual edit-compile-burn time, then put
it all back and restart the VAX - about an hour cycle time to
fix a bug. With the PromICE, since we booted our target board
anyway as part of the normal use cycle (not common in embedded
boards, but ours used host-bus-downloaded application code, so
we soft-booted our boards *lots*), the makefile handled the
compile-download-boot phase by itself, and our turnaround time
was more like 5 minutes.
It made debugging go really, really smoothly, especially when we
were having problems with one particular sort of VAXBI cycle.
