Type 011 Keypunch, IBM
YEAR: 1950
ITEM: Peripheral Device
COMPANY: IBM
COUNTRY: USA
IN OUR COLLECTION: Yes
The Model 011 electric keypunch was introduced in 1923. We are not sure of the year this particular keypunch was made but it wondrously still had a small paper "IBM SERVICE" agreement still attached. The service agreement indicated that this was installed on 1/25/1950. The Type-Serial-Suffix was given as "001-14358-AM" and indicated that this keypunch was "Customer Owned" and would be service "per call" as opposed to "maintenance agreement". The service agreement
The keypunch also had two metal tags attached to the front. One gave information about the new electric model: VOLTS: 115, CYCLES: 60, CODE: 011, AMPERES: 5, and PHASE: 1. The other metal tag was blue and silver and stated:
Manufactured by International Business Machine Corporation
