I'll remember that, thanks for the info.

I've found the info at Intel site thanks to David.

I've found some 8031's and used 8051's as well. Add an EPROM and let's
go....

Yep. They were throwing a whole load of emultors away. I collected some and
managed two make two working emulators out of it. But I stopped using the
8051 some years ago. I offered the emulators to some people for free but
nobody wanted them. So I took out the POD's and scrapped the rest.
