You are not alone! I ordered 5 cpus from RS yesterday. ;-) For what ? I do not know exactly. Rebuilding my first TRS-80 perhaps when I will be retired ? I spent so many years programming on this machine. As I didn't have enough money to buy floppy disk drives, I did everything on tape, with an oscilloscope in the way, to properly adjust the treble and bass to have a good square signal! During eight years ! Yes, it's definitely nostalgia. Nostalgia for a time when we tried to push technology to the limit to solve small problems, without having to manage dependencies, writing unit tests, doing upgrades ... Time when each computer has its own personality ...
