ga24-3231-7, 360-30 functional characteristics pg14 (from bitsavers) c30 8kbytes d30 16kbytes dc30 24kbytes e30 32kbytes f30 64kbytes .... univ had 709/1401 and was sold 360/67 replacement (for tss/360) ... pending delivery of 360/67, transition replaced 1401 with 64kbytes 360/30 ... gave univ. chance to get acquated with 360 ... but 360/30 could be also be run in 1401 hardware emulation mode. tss/360 never quite came to production fruition ... so 360/67 ran most of the time as 360/65 with os/360. IBM offered 2361 large capacity storage https://en.wikipedia.org/wiki/IBM_2361_Large_Capacity_Storage models came in 1mbyte and 2mbyte for models 50, 65, and 75. i also remember ampex (and other vendors) offering LCS up to 8mbytes, also additional memory for 30s & 40s. search engine turns up other vendors offering addon semiconductor/monolithic memory for 360s in the 70s with larger sizes at cheaper prices. -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
