This is one of the machines that meant a mile stone product for NCR
The Post Tronic was developed from the NCR
Class 2000, with a magnetic card reader/writer, and a coupled
paper tape recorder. This machine meant a technological breakthrough
for all banking institutions. It eliminated double bookings that generated
many mistakes, because mutations were put separately on the accountslip
and the customer card.
In one of the pictures of the Post-Tronic an NCR 461 papertape recorder
is shown. This recorder was equipped with a parity check for each
character. The machine stopped immediately when an error occured.
This parity check could be set to even or uneven parity check. Seldom
have I experienced that this error occured, which proves how well
this papertape machine was constructed
When the Post Tronic was developed allmost the entire company was
against the machine They believed that this machine would become obsolete
by the computer. But when Owen B. Gardner, head of sales for the accounting
machine department and later vice president, demonstrated the NCR
Post-Tronic to the banking industry, they became so enthiousiastic
that Stanley C. Allyn, then CEO re-activated the development of the
NCR Post-Tronic. That this was a good decision shown by the fact that
the machine stayed in use untill the end of 1970 at banking institutions
Some 4000 Post-Tronic were sold in 1959, 6000 in 1960 By 1960 the
Post-Tronic had been installed in 50 states in the USA and 20 different
countries, totalling a value of USD 100 million. Because of this success
NCR had quite some money to invest in the development of computers.
Experience gained with the Post Tronic was used with the development
of the NCR 390 computer.
The first Post-Tronic was installed on 22 April 1957 at Passaic-Clifton National Bank of Passaic in New Jersey. For the occasion 15 reporters were flown in from New York per helicopter to report on this newest NCR product. This demonstration was also seen by some 300 bankers and business people.
This memorable day ended with a big gala dinner and resulted in 800 orders.
