Microprocessor?

Although it's consistently referred to as a microprocessor, I am now far from sure it's in the usual sense as a (V)LSI device. Larsbrinkhoff (talk) 10:23, 30 July 2024 (CEST)

It's not. If you look in the documentation, Section 3 has a complete set of circuit diagrams for the CPU card (just one card!), and on pg. 9 (of the PDF) there's a list of all the IC's - and it's all SSI, with one MSI (a 4-bit adder).

Which does leave me somewhat curious as to what "microprocessor" meant to them. Some early DEC gear used it to mean 'microcode processor', but there's no microcode here; if you look in Section 2, there's a description of the execution of each instruction, and it all seems to be run by a state machine - i.e. hard-wired logic. I guess it just means 'miniature processor'! Jnc (talk) 13:05, 31 July 2024 (CEST)
