Yep. Confirmed. That's them. I hadn't heard of the RomRocket, but I
am familiar with the older stuff. Got one here that's rigged for 16-bit
operation. Great for 68K work.

If it was a genuine "Romulator", it may have been made here in Columbus
by a friend of mine - Grammar Engine produced the Romulator about 15 I had you beat on turnaround time
though, the Apple IIgs running LISA would let me make a change in the
source (30k to 40k lines total), assemble and download ready to reset the
target system and test in less than 2 minutes.
I was assembling on a VAX 8200 and squrting the binary out to the PROMice
over one of the internal console ports - not high speed output. 9600 bps,
but I'm pretty sure that described the bit time, not the bandwidth. We
dropped $13K on the CPU, RAM and disk controller. We did had them pull
the Ethernet and any other I/O to get the price _down_ to that! (later
we got another CPU card and I managed to fiddle around with console media
enough to get the CPU revs to match and, voila, an 8300. The last thing
I got to work in it was a couple of 4Mb VAXBI memory cards I got from a
scrapper for $10 each (he was going to strip the DRAM off of them) I have
a DEBNT but don't know how to install the cab kit).
Grammar Engine has been in the ROM emulation market since about 1988, give
or take a bit. I may be biased, but I can at least recommend their older
products.
