out the book - is the 8X300 the 'unusual', proto-DSP device discussed
in a chapter of the Osborne book?
I don't know if I'd call it a proto-DSP device, but it is/was a bipolar
microcontroller type of device. The Osborne book does a very poor job
at explaining its functioning--and then tries to fit the book's standard
"move bytes" benchmark to it.
Better is the Signetics "Bipolar LSI Data Manual":

Which gives a pretty good rundown on the whole family.
