Processor Technology - CUTS
Board
This was a very popular cassette data
storage board. CUTS stands for "Computer Users Tape System".
CUTS was a high speed (then), simple to
use audio cassette interface that operated at 300 and 1200 bps data rates under
program control. The recording technique used was asynchronously
Manchester coded at 1200 or 2400 Hz and is CUTS/Byte/ Kansas City Standard
compatible.
Two separate tape transport control
outputs and two common audio inputs and outputs were provided to drive one or
two recorders with this board. In addition, CUTS had provision for selecting 1)
a low level audio output signal for driving the microphone input to an audio
recorder, 2) a high level audio output signal for driving the auxiliary input to
an audio recorder, and 3) a 5-volt peak-to-peak square save output for driving
a digital recorder. A fully automatic gain control operated in the read
mode. Unlike other cassette interfaces, CUTS had absolutely no critical
adjustments that must be preset or adjusted during operation.
Processor Technology sold all their
software in CUTS format on cassettes (as well as on paper tape). The
format was widely used in the early S-100 days. However later the faster and more
reliable Tarbell controller dominated.
The manual for this board can be seen
