The midseventies SHARE survey 71

one of the issues of applying scarce resources to bldg new stuff or niche markets of retrofitting current stuff to old iron aka nominally 360-65s or above, you had to have a customer with reasonably large operation, and they need to buy large amounts of additional dasd and weren't going to migrate to faster, bigger, cheaper 370 to go along with the operation. memory on 360s was much more expensive than 370 memory ... typical 360-65 was 512kbytes ... you could at least migrate to 2-4mbyte 370-155 ... which had much less expensive real memory. However, a growing 360-65 shop that needed a lot more disk space was likely to also need a lot more real storage and memory and was likely to also migrate to 370-165.

note also a lot of the primary 3330 crew ... were part of the 200 disk engineers that migrated with shugart in '68 plus 1 ... leaving san jose with real shortage of people in the early 70s (it really was scarce disk engineering resources). even in the late 70s, i was being conned into going to high level disk meetings. the excuse they gave was that they still hadn't backfilled all the high-level "system" expertise that they lost in the large shugart exit.
