I have a TTi QTS-30 which is TMSCP tape only. No MSCP disk support. If
there are no jumpers (I don't have it front of me to check at the moment)
then it must be soft configurable through the 10-pin serial port interface.
Post a picture of your board or send me one direct and I'll see if it looks
the same as my board. If it is I can dump the EPROM firmware in mine for
you. Maybe two EPROMs for 16-bit wide firmware.
