As IBM FE in early 60s got to see all the old stuff still installed prior to the 1401s. Was supposed to go to 7080 school but cancelled at last minute and sent to fixing EAM stuff. Got to "penny a day" on a 1401 and hands on repair on some 1402s if it was card drive stuff. Amusing stuff was not paying attention to signing with penny a day, comparison for last day failed, the high speed 1403 probably went through 30 pages before I got it stopped.
First owned was 6800 SWTP starting with 1 K, ending with 6800 and 6809 mixed manufacturers, up to 48K and hard drives. Proud of hardware hacking a bitbanging serial port to make it SASI and driving up to 3 hard drives and 4 floppies on a WD controller. And the software hacks to patch in the drivers, most of which I wrote in assembler or machine language. Did the full TRS line as a leasing and service company with some basic programming for quick & dirty jobs, then transitioned into PC stuff when I finally saw the handwriting on the wall. Missed the MCA fiasco because the ISA stuff was still selling.
Jumped into a hardware problem when 3 other companies had failed to fix a machine, had to learn Xenix in the process, and ended up with a life consumed by SCO stuff.
