Summary
[edit]
| Description |
This vintage photo portrays the previous paradigm shift in electronic memory… This is a 64 bit (not KB, MB or GB) memory chip from the mid 60s on top of the industry standard at the time – core memory (hand woven iron rings that store a 1 or a 0 magnetically). One of the original IBM engineers, who first put memory chips into a computer, sent me this print. The chip is a SP95 Phase 2 Buffer Memory (The Phase 1 chip was 16 bits), produced at IBM Essex Junction, VT. SP95 was the first commercial application of IC memories in a computer (the IBM S-360, model 95 scientific computer that shipped to NASA in 1966). The IC grabbed the proverbial brass ring, and had its day in the sun. |
