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": http://bitsavers.informatik.uni-stuttgart.de/pdf/signetics/_dataBooks/1984_Signetics_Bipolar_LSI_Data_Manual.pdf Which gives a pretty good rundown on the whole family. --Chuck
