[GreenKeys] OT: CNC Paper Tape Readers

[Jeff G]

Ok, not teletype related per se, but figured your knowledge may cross over
here. I posted in a vintage computer email list as well, but figured I'd
ping this group.

Has anyone ever worked on one of the paper tape readers readily available
on ebay that likely have come from CNC machines. I was just wondering if
anyone has actually made these work?

It seems many of these have a standard pinout/spec depending on what CNC
controller they were connected to.I had one I bought some time ago, a
Sanyo-Denki 2401 model, and it seems this was often used on a Yasnac 2000G
controller, and has a 40pin ribbon cable connection, whereas others use a
50pin ribbon cable (on Fanuc controllers).

Just wondering if anyone has ever gotten one of these running, or perhaps
knows anything about them? I spent a couple hours with mine yesterday and
determined most of the pinout, but I don't know what voltages the power
input should be.

I have a bunch of notes and the data side is relatively simple, its the
control side I'm struggling to sort out.
