There are a few modded old machines. These range from Case Mod’s to full on emulation of an older system.
From Commodore 64 Computer Using Raspberry Pi
To Apple II
To TI-99 – RaspTI: Convert a Vintage Computer (TI-99/4A) into a RaspPi Workstation (One of my first Computers)
Raspberry Pi in a TRS-80 Model 100 case
Modding keyboards for USB in old devices
Keyrah V2 allows you to connect the keyboards of classic computer systems like the Commodore 64 or the Amiga 1200 to modern computers (e.g. PC, Mac, or the Raspberry Pi***) via USB
Then onto Gaming Systems:
RPi 2600 – Atari 2600 Suitcase Multi-Emulator
Raspberry Pi Sega Mega Drive/Genesis II Case
NeoGeo Arcade Cabinet
Then Custom Emulator OS’s with mini cabs designed around them
Video based on PiPlay
A cabinet with PiPlay (Formerly PiMame) configured for the cabinet and renamed Cupcade OS.
Then we have Emulation Station
And a cabinet that ships with that as a default Porta Pi Arcade (Kickstarter has almost shipped all units should be available on his site eventually)
Then comes the definitive all in one portable system case mod.
Pi2D2 – Wifi, Webcam, Video Projection, R2D2, and You!
Now this is portable gaming:
Emulation on the Pi is so much fun.
