  SC/MP single board computer by Bill Degnan - 03/28/2024 13:07

National Semiconductor started selling a CPU called the Simple Cost-effective Micro Processor, or "SC/MP". This image shows the SC/MP microprocessor at the heart of a simple system and current loop to RS232 converter. Click image for larger view.



Here is a closeup of the SC/MP-1. This is the first gen version, part number ISP-8A/500. It's clocked at 1 MHz and uses P Channel MOS technology. Note the silkscreen date.
This microprocessor was first available in April 1976. Click image for larger view.


More to come on this one. The builder of this SBC followed a magazine's design, working to track down the article, scan it, provide additional details, testing, etc.
