For the OMTI 5000 series boards, there were actually data sheets for the
3 custom chips (IIRC they were a buffer memory controller, the actual
data encoder/decoder and a VFO/PLL/data separator thein). Those data
sheets did (IIRC) document the various registers in the chips. So it
should be possible to completely understand the firmware.
