The TD8E can't read LINCtapes without putting an inverter in the clock line.
With it still wasn't great. Code I used depended on the databreak interface
board I made for formerly online PDP-8. Being slowly reworked to get rid of
the obsolete java front end and dependance on a parallel port which my new
server didn't have so will be back online at some point.

Currently I use a beaglebone that connects in place of the TD8E. Works
better but code gets confused at times with errors. Really needs a rewrite.
Also doesn't like most of the LINC-8 tapes I have. Haven't had time to
figure out why.
