I just keep all of my music in an NFS share on my NAS and play it with Rhythmbox or VLC. I keep a compressed copy on the SD card in my phone to listen to when I'm not home.
I ran Damn Small Linux on it about 15 years ago. That worked pretty well and it would even run a web browser. It would probably boot Tiny Core Linux, but there wouldn't be much RAM left to run any programs. The motherboard supports 128MB, but it's not really worth the cost to upgrade it though.
I may see about resurrecting that computer. I've got an old Motorola police radio that I would like to reprogram to operate in the 2M ham band and I think that PC will run the programming software.
Don't install their apps either unless it's on an old phone that you've wiped all of your personal data from.
That's what I've been using lately. It prints great at 300 mm/s. It's reasonably strong and doesn't string much as long as it's dry.
It's certainly not an ideal solution, but it's an option that will usually work.
I've used Optar. It works a lot better than just printing some QR codes. It fits 188 KiB on a sheet of letter sized paper after error correction. It does require a laser printer and a flat bed scanner though.
There are HDMI splitter boxes you can get from China that conveniently strip out the HDCP.
He should hook that control panel up to an emulator and make it work again.
I've run Linux on a 166MHz Pentium with 64MB of RAM. There's not much modern software that will run on that hardware though.
Install RetroPie and turn it into a game console. It's got plenty of power to emulate a lot of older consoles. You can even connect some game controllers from old consoles to the GPIO pins.
