Altair 8800. Make your own on a budget!
Using a TTGO VGA32 V1.4 I demonstrate an independent Altair 8800 clone that connects via VGA and PS/2 keyboard. The nice thing is you don't need a PC at all once it has been set up. System runs CP/M 2.2.
TTGO VGA32 details here: http://www.lilygo.cn/prod_view.aspx?T...
TGO VGA32 consists of a VGA port, PS/2 keyboard & mouse ports, micro SD slot and 8 GPIO pins.
Check out FABGL on google for firmware etc.
