Early bird: VIC-42?
Added 2021-06-12 23:22:43 +0000 UTCUpdate: And just like that the mystery of the VIC-42 is apparently solved!:
"Mike [Naberezny] determined it's the uC in an AlphaCom VP42 printer (not the 42). Mike scoped out a few pins and it appears to be a 6500/1, same uC in the 1520 plotter, and which can hold a small program: https://e4aws.silverdr.com/hacks/6500_1/ " - Src: Jim Brain, Commodore International History Society Facebook Group, with thanks to David Wood
So there we have it! It seems to be a 6502-core based, single chip computer, printer controller, used by Alphacom! I got close; I had the innards of an Alphacom 42 photographed a week ago and found no VIC, but I couldn't find a VP42. Not quite as exciting as we may have hoped, and strange to me as VIC stands for Video Interface Chip, but very cool to know nonetheless. Well done gents! Mystery solved, and so the VIC-rolling can end! ;-)

Dear Supporters
Earlier this week patron Kevin Gonzalez alerted me to a "VIC-42" chip that had appeared on fleaBay. There was no info about in on Google, so I bought one and it arrived today. I thought I'd bake a very #Shorts little recipode about it. The plot (and recipe) thickens...

I think this might be something we just have to make up a story about. "There I was, wire tying a Commodore 264, when I was attacked by a Spectrum..."
