repairing/testing 82161a IL issue using 82162a

[dmh]

Hi, I have a working 82162a printer (slight paper advance issue) and an unrecognised 82161a tape drive that powers on and rewinds the tape but gives "Transmit Err" for anything else (after AUTOIO). The IL module works as I can print to the printer. I powered both devices in the same way and tested them separately as the only device in the loop.

I'm looking at ways to easily verify what is wrong with it and then work out my options and was wondering if it could just be the IL part of the tape drive and whether I can swap it out of the working printer to test.

Any advice appreciated.

TIA, dmh
