I'll have to open up my PDP-11/83 tonight. Its

writing, as long as what's being written can be read reasonably fast
from (RQDX3/RD54) disk. The TQK controller is sitting right up at the
top end of the Q-bus, to get high priority -- but I don't know if it's a
TQK70. I've really just assumed it's a TQK50 without thinking too much
about it...
Turns out it's an M7546; a TQK50. I guess I'll get streaming writes
more often with an M7559 (TQK70) than I do at the moment, then. :)
