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.
