Very likely one of the Western Digital products. They were the first to take UCSD Pascal and burned the p-code interpreter into the ROM. Made for a blindingly fast system. I worked with the folks who did the port and make it all play together. Fun days.

I worked on the OS and various utility programs those days. Nothing to do with the interpreters.

When the 68000 came out SofTech did a port of the system to it. Worked very well; you could take code compiled on the 6502 system write it to a floppy, take the floppy to the 68k system and just execute the binary. It worked amazingly well.
