thank you for your nice feedback!
I have quite a few retro-items that I'll repair one day (beeing all my
stuff, I don't feel the pressure to do it "now").
I'm studying the possibility to build modern replacements for the MOS 8701
IC which failed on one of my C64, but I'd rather not build a complete PLL
circuit like the old clock generator pre-8701 (for some reasons that I'll
gladly explain to the ones interested if they drop me an email).
If someone has a good experience with VHDL or CUPL and feels like helping,
just contact me :-)
MOS 6522 and 6526 are even easier to "re-implement" on a modern programmable
logic, but I think there's plenty of these chips at the moment.
