retroelectronics is a slog and you will not "solve" any of the problems you have with it. you will not get a pentium 3 or a mac or a videotape recorder that you can set down and wire up that will do everything you want and can be trusted to work every time you touch it because that's not the nature of the beast you've chosen to ride. this hobby will exist on a treadmill, always getting a new, slightly-less-janky version of every item, and when you say to yourself "this is now the best one i have," know then that someday you will be saying it again about an item you don't yet know exists. enjoy everything enthusiastically while you have it instead of treating it as simply a tool and a fixture that will follow you through life. this might be a metaphor for more things than just VCRs, there is no way to know
