DIGITAL READOUT COUNTERS
On the contract for the three 2-axis counters, the first unit
is complete and tested and ready for final tests by recording
the output on magnetic tape.
The second unit is wired except for the control panel which
is in process. Wiring on the third unit is just starting.
All the circuit boards are complete including--the spares and
are being tested in the first unit. On the 4-axis unit,
the engineering is complete-but manufacturing has not started.
The cable length information has been received by lI On STAT
the 2-axis units the cables are various lengths from 8 in,
to 3 ft as required for stacking the counters. For the
4-axis unit the cables will be 15 ft long.

changes were needed and the remaining trouble appears to be

receiving dataphone looked good on the scope. When the two
dataphone chassis are not grounded together, a 60-cycle
noise modulation appears on the transmission as observed by
the scope. It is possible the noise modulation may be the
result of the oscilloscope grounding and will check
this out by making magnetic recordings. He was working on
the magnetic recordings today, Thursday, and expects to have
an answer tomorrow, Friday.
