<programming job was to upgrade an 11/780 from 2.4 to 3.0. It took most of <weekend, not helped by the fact that you had to install different versions <of the microcode at various points during the upgrade, and it took 30+ Yes, there were a lot of people that suggested the next upgrades should be easier. <minutes to discover that you'd got the wrong one in. The 8" floppy on an <11/78x was not renowned for speed. ISTR that the interface was one bit wide The LSI-11 to vax hardware was wider I think 16bits bt the microcode was some 60-80 bits so it took a long tome to build a few words of uCode. Allison
