I was just reading about 1103's in The History of the Advanced Scientific
Computer (aka, TI ASC), here,
There was strong evidence that semiconductor memory would
replace all other forms of memory then in use. Thus, a project
was set up under George Quimby to investigate memory alternatives
(Appendix G). Two memories were finally developed, high speed
bipolar main memory (first installed in May 1972), and a lower
speed MOS attached memory (first installed in mid 1972).
We were one of the earliest users of the 1K Intel 1103 device.
We had a contract with a firm in Canada who had government
money to get into the semiconductor business and had an agreement
with Intel to produce the 1103. I remember this firm never made
it and folded in the mid 70's.
