I looked in my intel 1990 book and it looks just like the ISBC 80/24A card in
the book with a 8085-2 processor and ISBX connectors for the Mezz card.
Normally the card has edge card connectors on top. It looks like someone
soldered header connectors to the edgecard ones.
I just got an Intel 80-10 rackmount chassis with a 80/10 processor (8080
chip), a National Semiconductor 2 port memory card, an analog devices RTI 1200 and
an intel SBC-108 combination mem & I/O expansion. Looks like it needs some
cleaning to get it fired up.
