Hi folks,
I was recently given a load of QBUS stuff, and among the cards is a TD
Systems TDL-11. I can't find a scrap of information about it anywhere.
I have reason to believe it's a SCSI controller that emulates RL01
drives, based on its similarity to the TDL-12, which is documented
online here:

Do you have access to an EPROM programmer? Before someone turned up the
manual for the TDL-12 I found enough clues to figure out how to start the
onboard DMON configuration utility be examining the contents of the EPROM.
A dump of the EPROM should also show whether or not there is even an
onboard configuration utility.
Are the major ICs a Z-80 CPU, plus a couple of 8255s instead of a more
typical NCR 5380 SCSI controller?
