Another option would be to spin the data onto

I think he used a custom controller.
I have several TD8E controllers, but the TU56s are wired for the TC08, and
one unit for the TC11.
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.
