If my memory is correct, Commodore created the 6560 with the hope arcade machine companies would buy it and create video games for that circuit.
The VIC-1001 and later on the VIC-20 came into existence when only a few samples were ordered by development labs and Commodore was stuck with a few thousands of these chips they couldn't sell.
It makes sense the first VIC-1001 and VIC-20s would have been equipped with surplus 6560 made in the previous years.
Does anyone have any idea what the last serial numbers were for the PET-keyboard machines?
I just bought serial number V059443, made in USA with PET keyboard. Looks in good cosmetic state - will have to see if it works 'out of the box' when it arrives.
I will pay attention to the fuse holder. I remember having issues with that in my VIC back in the 80s too!
I also have to source a power supply for this machine but since it is just 9VAC it shouldn't be too hard to find something.
The machine was cheap because the PSU is missing. Apparently the vendor tested it for an hour or two with a borrowed power supply (good to have friends with VICs I guess!)
