Hi
I have a working motherboard but no screen and no keyboard
I'm working on an interface to display the cbm 8032 screen on a standard 
flat screen
and on an interface to replace a cbm keyboard by a ps/2 keyboard....

for the screen I made a vga board (it works) but the vga cable is so 
heavy that it has a tendancy
to remove the board from the 6502 socket...

for the keyboard it's also partly working but not fully usable

with the covid I stopped these developments  (no way to order a pcb with 
a decent delai)

(I'm just restarting...)
I restarted with a new approach: convert the video signal to vga with a 
fpga (ice40up5k)
