I've started scanning a few more of the BHP docs I recovered a while back, and thought this one was interesting. A 1973 gizmo that buffers just enough received data for a relay to close and power up a teleprinter's motor to operating speed before printing, apparently half a second was sufficient it reckons. The buffering is through a pair of 64 x 4-bit Fairchild 3341 FIFO memory chips. https://archive.org/details/utec-bmc-6092-buffered-idle-line-motor-control-for-asr-33-teletype-instruction-manual
One of the other docs mentions they had an ASR33 with this buffered motor control installed connected to PDP-11/10. Steve.
