DIGITAL READOUT COUNTERS
There is some confusion as to which Model Counter I uis
to provide on the current order. There were two models
made on the previous order. They were:
Previous Order for Two 2-axis Counters
1. One each Model 2825A Control Panel
One each Model 2827A Synchronizer
Two each Model 2826A Counter with input amplifier,
with 5-volt lamp power output connector, and with a
multipin output connector for 15EL44 amplifier power
for the sensing head.
2. One each Model 2825A Control Panel
One each Model 2827A Synchronizer
Two each Model 2826B Counter with input amplifier
for the sensing head and with no
extra p nectors.
The Present Contract for Three 2-axis Counters
One each Model 2825A Control Panel
One each Model 2827A Synchronizer
Two each Model 2826B Counter with input amplifier for
the sensing head and with no extra
power output connectors.
This is what is being built and this is what
requires, however, the contract calls for Model 2826A
counters. A contract change is required and I understand
is preparing to issue a change.
The present contract for one 4-axis counter is denoted
the Model 2826C with input amplifier, with 5-volt lamp
power connector, and with a multipin connector for 15EL44
amplifier power for the head. The Model C is
the same as the Model A but is configured differently due
to the different physical arrangement. Also, the zero
reset and preset reset pushbuttons have been deleted.
The functions will be controlled remotely by customer
equipment.

Digital Readout Counters 17 August 1964
I believe the above information correctly indicates what
Dis building and what John wants delivered.
The situation was hopelessly confounded last week when
erroneously told me the opposite. He had said
on August 10 that the 2-axis was being built for the
heads and the 4-axis was being built for the
head. This information naturally confused
o n w en reported it in my last report.

cannot tell as yet what the interlock problem is. They
may, however, find the answer when they get the data
phones. They can undoubtedly find the problem when they
operate the 2-axis system now being com leted with a
data phone. Sending the data phones to was a sound
action in my opinion.
For the first 2-axis system, the counters were completed
is completely assembled and wired. The synchronizer
wiring is nearly done and will be completed by tomorrow.
Checkout of the chassis will continue through the week.
