Hallo all,

in case you haven't noticed, I have investigated the VIA shift register
bug together with Dave McMurtrie and Martin Thierer, and got some news
from WDC about it - all published in my latest two YT videos (still have
to write it up...)

Oh, btw. I implemented the Commodore Fast Serial bus with a VIA shift
register as well. Code is here
