You know, with a 8086 onboard, that thing has to have a ROM/PROM on
it somewhere with firmware for the 8086. Why not dump it and see if
Why?
It would be entirely possible to have the software for the 8086 in the
RAM that's on that board. Load the RAM from the ISA bus, then enable the
8086 (say by de-assertign the reset pin) and let it run.
I have at least one DSP card for the ISA bus that had no ROM on it. Just
the (ROMless, I hasetn to add) DSP, a lot of high-speed RAM, the analogue
interface chip and buffer amplifiers and an ISA interface circuit.
