Just for who's interested, I have still lots of PCBs and parts lying around 
for the C2N232I, including the matching pre-machined little plastic cases. 
Unfortunately, it is not easy to build (aha, the third problem!), and I 
have no time doing so. Not to mention problems with todays laws regarding 
production and distribution of electronic equipment, which I can't fulfil. 
Those who tried to build it on their own know very well that it is quite 
tricky to assemble it without mixing up some parts.

I justed wanted to answer that I never heard of this device, but after 
reading about it, I remember you talked about such a device long ago.

Nowadays, there is also the Final Expansion 3 and other multi-cartridges 
for the VIC-20. Being very late to follow these developments, I just 
ordered empty PCBs from for the FE3 and found that some 
parts on it became obsolete already. I think I managed to source them and 
I'm curious how it will work for me. The big advantage, in my opinion, is 
the inclusion of a well working SD-card IEC device (SD2IEC) on the cartridge.
