bad6502 update 9 - now as a Raspberry Pi 4 Hat

The chip shortage is upon us - nothing can fix that for now. So let's build a vintage style computer from parts that are available - and as little of them as possible. Impossible ? OpenSource ?

Update 8:

• I updated the PCB layout to a Pi 3/4 Hat, but kept the 5V in and power switch

About the bad6502: Presenting the bad6502, the 35 Dollar 6502 based computer that has needs no chips. Features (subject to change):

• HDMI
• USB keyboard / Mouse
• 1+ MHz WDC65C02

Ok, honestly: ... its a 65C02 with emulated hardware on a Raspberry Pi Zero 2W. But it's cheap and fun and available now. Still fiddling with the hard and software a lot.

More soon !
