< Yes, but DEC had a strange definition of 'microprocessor'. They sometime < used the term to mean 'microcoded processor' - as in the microprocessor < board for the DMC11, etc which certainly wasn't a single-chip processor < (it was a hex-height card of TTL). Microprocessor... the RX01 disk controller (drive end) is a board of ttl and proms. It is a micro, meaning small, processor, it performs a set procedure of actions "process" upon data or system (disks and the data for them). The RX01 contains a microprogrammed microcontroller as its microprocessor. I'd think that was clear enough. ;) Allison
