Interesting, I don't think we've seen this board before. There's 16K RAM on there so possibly being used as sideways RAM rather than shadow RAM.Photo of the PCB
Are you able to dump the TCL ROM?
If you search the forum for 'Boxford' you'll find other versions of the TCL software that has been archived, but no info on the hardware.
