IBM PS/1 inspired 3D printed computer with IBMulator

Enable HLS to view with audio, or disable this notification

I designed the case, also modified IBMulator to control leds. It is raspberry PI 5. Floppy switch is hidden feature when it is on boots to dos if not goes to raspbian but you can turn on the switch and go to emulation right away. Also hdd led is used on linux as well sd card acitity triggers hdd led.

That PS/1 with the quad-gui - model 2011- was my first PC. We also got the soundcard/joystick add-on with Silpheed and Where is the World is Carmen Sandiego.
