Well a genre of music I used to listen to was called Chiptune
it's mainly made using Gameboys but it can also be made using Commodore 64, ZX Spectrum, and many other things that I can't name off the top of my head because I've been out of the scene for quite a while now
but a few chiptune musicians I enjoyed were:
• Dubmood
• Chipzel
• Zabutom
• Gem Tos
• Fighter X
• Sabrepulse
• Wiklund
• Zalza
and if you want to listen to some stuff I have made,
here you go
