this beastie.
It's a National Semiconductor Microcomputer Systems BLC 80/10.
Clone of an Intel iSBC 80/10.
Single board 8080A computer with sockets for PROMs and 1K of RAM
onboard, several parallel ports, one serial port, and Multibus
interface for expansion. As used in this case, it was standalone with
only the power pins on the Multibus connected (and the I/O at the top).
As the only Multibus backplane I have is an IRIS 3000 series
(double-deep), it's available.
I remember vaguely running into some literature that mentioned multibus some
years back, but I never encountered any of the actual equipment. Heck, the
literature didn't even mention prices, though I got the impression that it
was kinda spendy compared to some of the other choices that were around at
the time.
Is there much of this stuff out there?
Any pointers to technical descriptions and such? I really don't know much
about it and I'd like to rectify that...
