Building an IBM PC XT from SCRATCH

Описание

This is part 2, part 3 is already live here: https://youtu.be/Ys7RXkzbXw0

Things are moving along. In this video I'll install a VGA card and somehow get a modern USB keyboard to work with this 40 year old 5160 IBM XT PC motherboard - hint: It required some Arduino code.
After that I finally get some Basic programs running - and we get to see how it compares to Basic on the 6502.

Part 1 of this series is here: https://youtu.be/Faqy23HcPiQ
Part 3 is here: https://youtu.be/Ys7RXkzbXw0

The source and keyboard adapter schematic is here on Github:
