Re: I finally have the parts to complete my Amdahl 470 V5 restoration.
Sometimes it's the journey, not the destination :-)
I restore old shit as a form of meditation. Cars, boats, bikes, cycles, aircraft, computers, farm equipment pre-steam age & steam, name it ... Some stays with me, some is sold, and some gets loaned to museums.
However, my nieces & nephews are learning about the history of programming as a result (so did my daughter) The oldest niece is soaking in assembly language (multiple CPUs, ancient & modern) at a dizzying rate, and she's also pretty good in Cobol & Fortran. My oldest nephew is a whiz in Cobol & Fortran, and getting help from his cousin in assembler. All the kids have to use Windows at school, but I'm slowly teaching them how the clusterfuck came to be, starting with DOS 0.96 beta and all variations through the early world of Windows.
Why? They are interested, that's why. And someone in the next generation is going to make a fortune maintaining the now 40+ year old code that most of the nation's infrastructure runs on ... as my daughter is discovering already :-)
