Thanks Michael! It seems to be "industrial strength" - I'm sure these were priced above the affordability threshold for most hobbyists...

I've acquired an Intel SBC 80/10 and the associated SBC-108 I/O RAM expansion board plus a card cage. These appear to date to '76 and, as I understand it, were the beginning of what eventually became branded as the Intel Multibus (later an IEEE standard). These have ceramic Intel
chips.
Look to be in pretty clean shape. I've found manuals/docs on the internet for the SBC 80/10 but not the expansion board. * Glenn
The manual for the SBC-108 is here: http://bitsavers.trailing- edge.com/pdf/intel/iSBC/980277B_SBC_104_Memory_IO_Module_1976.pdf
Decades ago I ported CP/M 3.0 to that processor board. I had a framebuffer for the console and 128k of RAM. I used the parallel port to control the upper memory address lines for the memory paging.
