We Have two copies of employment applications  Form ED 1033 Would date this in the late 1950's as it refers to 1960 in a future sense in the text which is reprinted below.
(Editors note: We were always taught to take  three applications when we were filling them out, perhaps we can assume Jack got the first one right and the other 2 copies went into his file cabinet)

A pin pack button issued at the launch of the 'Head-per-Track' disc system. Unlike today's disc drives that had moving head systems, each track on this old disc system had a fixed head.... one per track! The platter was huge! We have one on display at the museum!

What Bank or S&L in Arizona were these shot?

2BC1-1 Board

I can positively identify the 2BC1-1 PC as a channel card from the first
B-100 Sorter-Reader developed in Paoli in the late 50's. In addition, it
had a small plug-in "piggyback" card containing a set of resistors
representing one of the "signature" for the 14 different characters in
the original MICR character set. The character recognition system
consisted of a read head , pre-amplifier, power amplifier, delay line, 14
channel cards and summing amplifier. The program was led by Walt Hanstein and I was a junior engineer who worked on the system development. - Ralph Parris

Thanks Ralph! tell us some more! Fascinating!  Any one want to add some more info? Does anyone have prints for this card or other docs? - Ed Sharpe Archivist for SMECC

Readers additions - The 3 vacuum tube may have been made at the Plainfield NJ plant. As I remember, there was a firm named Haydu (sp?) Brothers which was absorbed by Burroughs in the 50's time frame.

I worked for Burroughs/Unisys from 1955
until 1991 at the Paoli Research Center, 2nd Ave Detroit Engineering,
Plymouth Michigan Manufacturing, and Rancho Bernardo CA Semiconductor
operations. - Ralph Parris
