I have to say that the Crappy Keyboard works quite well on the #vickytwenty, and seems it is wired correctly too!
Of course it's crap to type on (hence the name), but great as a test device, and I can use the schematic to build a custom mechanical one in the future.
The only thing I wanted to improve is debouncing of the caps lock key, so I bodged an RC network for this purpose. I've integrated it in rev.1 of the board, so no need to do the same on the version I'll release.
#vickytwenty board finally booting! With a sovietic 6502 clone in it, a ridiculous stack of sockets for the ROMs (waiting for my adapters from JLCPCB to arrive to fix this) and a B/W image (I did the #svideo mod, but connected only the luma signal for testing).
The character rom has a bodge wire on it for the second /CS signal. I totally forgot this one was a 2332 and required both select signals to be handled by the VIC.
So many ZIFs!
Waiting for a package from #mouser tomorrow. Should contain some more 40pin sockets, so I can build a raised one for the VIC, and two W65C22N to use as CIAs.
Thinking if it's worth placing ZIFs for the CIAs too. I'm expecting to test those less frequently, but at this point might just go all the way, right?

The S-Video mod of the #VickyTwenty worked out. It is not so visible here, but it is sharper and the colors are less blurred. First, the retroTINK was set to the wrong mode and it looked shitty… phewww… VIC-20 A/V-Adapter Rev. 1 #Commodore #VIC20 #SVideo
