My use of old computing technology is really in support of old music synthesizer technology. For instance my Yamaha VL1, one of the first and greatest waveguide physical modeling synthesizers, does not allow full editing of the model parameters from the keyboard itself. Yamaha made a few editors for it that use MIDI SYSEX to edit the models. Unfortunatley those only run on MacOS System 7. So I have to keep an ancient mac for that. Many of my synths use 3.5" floppies. The ones that use FAT formatting can easily be used with a USB floppy on a modern computer, but the ones that have their own proprietary disk formats (most of them) require software with direct access to the floppy that can't be got through a USB connection. So, for those, I have an old Windows laptop with built-in floppy and software like Omniflop to manage those disks. Probably one of the greatest things to make old tech more manageable (for me) is the SCSI2SD project, which makes an SD card into a SCAI device. Since SCSI was hugely popular with classic samplers (synths that can record audio and use the recorded audio as the sound source in the synth sound) I have a half dozen SCSI2SD drives so I don't have to keep ancient parallel SCSI dive alive.
