To clarify: Firefly is an internal-only device built by DEC research in Palo Alto. It wasn't a product and as far as I remember wasn't the basis of one, either. There are some DEC SRC reports that describe aspects of the Firefly. I think Modula-3 was invented for it, but I may have my research platforms mixed up. paul
