I beelive a lot ot Tektronix storage tiube devices, not just terminals,
ahd this interface. So your printer controller would hav wider applications.

I thought it was partially photographic, which a 1-line CRT (a very odd
looking tube) pointing at light sensitive paper. But it's been a long
time since I was inside one.

I was very happy with this project until I read that part. I am totlaly
in favour iof making modern peripherals for old machines. But I really
don;t like stripping classic hardware for no good reason.Sure the paper
for the 631 is unobtainable now. But I still feel the design of said
printer is interesting, and they should be preserved if possible.
