I don't know of any transputers with on-chip ROM,
which model would that be?
No transputers (AFAIK) have user-programmable ROM, or even mask ROM space
that can be programmed as the user wants if you bought enoguh chips. But
I'd assumed (and I think the data sheets confirm it) that the bootstrap
program that downloads a probram over one of the links was stored in a
ROM in the transputer.
The 801 is the SRAM optimised one (separate address
and data buses); the
805 is the 800 plus the break instruction and the Event Waiting pin.
Thnaks. I have a couple of T801s somewhere...
