Some time in early/mid-1970s, I did a competitive procurement of quarter-meg upgrade for 370/145 going from 0.5MB to 0.75MB. Evaluated several vendors, checked specs/references, etc. Spent about (as I remember) $30,000. A while later did the same for 370/148 1MB upgrade from 2MB to 3 MB, same price.

In the early 1970s when I was working at Wayne State, we had a model 65 that was later converted to (or replaced by, I don't remember) a model 67. At some time during its life, we bought a few megabytes of Fairchild semiconductor memory that came 256K bytes per box with a price of about $250,000 per box. My understanding was that it was less expensive than the core memory that came before it. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
