"I'm currently creating my own retro 80's/90's gaming sample library..."

That was my first job in the late 70's repairing pinball machines, jukeboxes, early video games then to just later video game machines then that got me into computers, audio gear repair then that got me into recording for musos and websites then Biab/Realband.

You can get all those old game ROMs now and run on MAME (Multi Arcade Machine Emulator), I remember they used to be big logic boards some multi layered that cost $$$ with the same 28 pin JAMMA connector you could change from machine to machine.

Actually I just converted someone's old cathode ray tube arcade machine over to an LCD 600 game MAME.
The last time I was building these machines they had 3 buttons now they gotta have 5.
