I was an undergrad during the early '90s. Although I had plenty of access to computers on the campus network, I always lusted after real hardware of my own that I could run at home. Spent years at junk shops, auctions, and swap meets. Came really close to getting a number of systems working...except for that one part I could never find. Or software that was unobtainable. Or RD52s that last just about long enough to find out that my install media is corrupt. Little bitty disks, slow CPUs, not enough memory. Eventually gave up and donated most of my hardware to others who might carry the torch farther than I did.
But now, SIMH is like the promised land! Not just one machine brimming with tasty hardware, but as many as I want to instantiate! And between all of them, they occupy zero volume and have no mass. Moving a KL10B in the middle of the night was fun, but virtual machines that I can spin up and play with without becoming an equipment roadie and amateur plumber...Priceless.
