| May 12, 2022 at 3:23 | comment | added | HABO | I went to High School in the mid 70's. They managed to upgrade to an Alpha Interactive Computing Environment (ALICE) system for the students while the administration went on about business using Unit Record Equipment. (It's hard to calculate payroll when your plugboard can't handle multiplication.) A favorite feature was that even with the console locked you could set the switches to 136310 octal (IIRC) and the O/S would halt the machine shortly thereafter. That effectively unlocked the console and you could "correct" your privileges before hitting Continue. BZUP anyone? | |

| Nov 14, 2018 at 8:48 | comment | added | Ira Baxter | @paxdiablo: Data General was a damn funny place. It spun out of DEC, the Nova being a DEC-internal competing design for their planned 16 bit computer product, for which the PDP-11 design won. The Nova was spectacularly successful because it was cheap, cheap because it was incredibly simple internally. Because of this it was easy to copy so was cloned several times, including by EDS itself. One of the clone makers, Keronix (I helped them design a clone!), had a plant burn down, and fingers were pointed at DG's president DiCastro but nothing was ever proven. | |
