GENERAL INFORMATION
1.2.1
CUTS Description
CUTS, The Computer Users Tape System is a high speed, simple
to use audio cassette interface that operates at 300 and 1200 bps
data rates under program control.
The recording technique used is
asynchronously Manchester coded at 1200 or 2400 Hz and is CUTS/Byte/
Kansas City Standard compatible.
Two separate tape transport control outputs and two cornmon
audio inputs and outputs are provided to drive one or two recorders.
In addition, CUTS has 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 out-
put for driving a digital recorder.
A fully automatic gain control
operates in the read mode.
Unlike other cassette interfaces, CUTS
has absolutely no critical adjustments that must be preset or
adjusted during operation.
1.2.2
All Processor Technology software is
available on CUTS cassettes at lower
cost than equivalent paper tapes.
Receiving Inspection
When your kit arrives, examine shipping container for signs
of possible damage to the contents during transit.
Then inspect the
contents for damage. (We suggest you save the shipping materials for
use in returning the module to Processor Technology should it become
necessary to do so.) If your CUTS kit is damaged, please write us at
once describing the condition so that we can take appropriate action.
