The Alpha was started by DEC in 1988 as a replacement for the VAX, it extends the address space to 64 bits and switches from a CISC architecture to a RISC architecture. I've got a copy the Alpha Architecture Reference Manual (AARM) and the Alpha Architecture Handbook (AAH) which combined give you everything you need to know about the Alpha. They're extras. I'd like to offer them in trade to anyone who has EITHER: KA640 Technical Manual KA680 Technical Manual Also published by Digital. --Chuck
