> I liked HP-UX having previously worked on IBM RT systems running AIX, as well as NCR towers with there more vanilla System V. There's very little on the internet about those "NCR Towers." > 1987: https://www.techmonitor.ai/hardware/ncr_marries_its_tower_unix_boxes_with_fault_tolerant_9800 https://www.techmonitor.ai/hardware/ncr_marries_its_tower_un...: "Despite abandoning its effort to implement Unix on its NCR 32 chip set, NCR Corp did not abandon its ambition to bring Unix into the mainstream of its mainframe product offerings, and the company yesterday launched a facility whereby its top-end multiprocessor Series 9800 fault-tolerant mainframes can be used as servers to a network of 68020-based Tower Unix supermicros." > 1988: https://www.techmonitor.ai/hardware/ncr_renews_its_tower_unix_family_with_major_enhancements https://www.techmonitor.ai/hardware/ncr_renews_its_tower_uni...: "When you sell as many machines as NCR does with the Tower, you can’t rush to incorporate a new chip as soon as it arrives because there simply aren’t enough chips to meet your needs. Accordingly the new Tower models use the 25MHz 68020 rather than the 68030."
