I never saw Computing Today.. However the apnotes and the databook for SC/MP

an 8A-600(Nmos sc/mpII) and the 8072 (third version with NIBBLE in internal
rom). Turns out that a few inverters sorts it all out and I went for a dual
processor version and using one cpu to report on the other in a crude debug
monitor. I later used the 8a600 as an IO processor for the 8072 nibble chip
as a unique system to explore the useful techniques for multi cpu systems.

Hi there
folks. I just got a sweet NS LCDS (low cost dev system) with
a SC/MP II processor card and nice set of docs on the chip itself, the
lcds,appnotes,and assembly programming It looks pretty easy to add
more than one scamp to the same bus and I was wondering if there are
I rememebr an article in 'Computing Today' magazine _many_ years ago, I
would guess around 1980. It was to add a second SC/MP to the Science of
Cambridge MK14, so that you could, for example, run the monitor program
on one chip and a user program on the other.
