1. On 1 October 1959 a visit was made to 25X1
to discuss Contract 146-192 - ersons con? acte 25X1
nt the contract side of the house and
are the project engineers.

2. The discussion was centered around the specifications 25X1
for the printer. Several problems have arisen in regards to our re-
quirements for this rioter of which some of the solutions should have
been evident to engineers. The printer in general will 25X1
have the following specifications. It will accept 5 bit parallel code
up to 300 characters per second. The input signals required for the
Burroughs printer are 0 and -12 volts. The power requirements have
been set at 105 to 125 volts and 210 to 250 volts. Both voltages will
work at 50 or 60 cycles ?5~0.
3. The printer was originally supposed to acce t standard teletype
code and be capable of single and double spacing. can accept 25X1
standard teletype code at 1600 wpm, which we required, but only with
single spacing. The highest s ed that can be reached with double
spacing is 900 wpm. The engineers will look into the double 25X1
spacing problem and see it cannot be solved. It seems that the
printer cannot accept normal teletype functions at the end 25X1
of a line, i.e., the carriage return and line feed functions. It will
be necessary for the printer to recognize the carriage return and line
feed at the same time. Carriage return is made automatically by elec-
tronic means on the ~ printer. Twenty milliseconds is required 25X1
for the printer to space to the next line. This means that approximately
three of our teletype characters (6.25 rr.~ts~character) are required
to give them this 20 milliseconds. It will be possible for the printer
to recognize a carriage return and line feed as separate functions
when these functions are sent other than at the end of a line.
~+. The delivery of the printer may be slightly later than scheduled.
The original delivery date was 1 April 1960. This is due to the fact
that the Air Force may have greater priority than we do. It appears
that it may be worthwhile to pusY~f~ eater priority on our part. The

Air Force is presently conducting severe tests on the printer. This
first article type of testing is naturally worthwhile for us so that
ve may get a reliable printer.
