Denial

Does anyone either have a Cardco Cardboard/3S 3 slot cartridge sport expander manual they could scan and upload here, or better still know where I could find a scan of one? My googling skills have failed me.

I was able to find the dip switch settings, but not a copy of the manual

Dip 1: Slot 1, block 5
Dip 2: Slot 1, block 3
Dip 3: Slot 2, block 5
Dip 4: Slot 2, block 3
Dip 5: Slot 3, block 5
Dip 6: Slot 3, block 3
Dip 7: Blocks 1 & 2 for all 3 slots

My heart sank when I opened the box and manual wasn’t there. Fortunately I found it in my manual drawer. I will scan it in the next week and post it here if you are still looking for it. FYI the 6 manual is very similar and has most of the same material. https://commodore.bombjack.org/vic-20/h ... _6_VIC.pdf

That would be great. I have the 6 manual, and it's available online, but I haven't been able to find the 3manual.

Same here

Could not post the pdf here, so it is available at https://www.mediafire.com/file/qoskqtn8 ... 3.pdf/file

You should send this to David so it is preserved on the Bombjack archive

If you have compared the two, they are mostly the same with the exception of the differences between the 6 and the 3 switches and it's cabling.

And going on a year later, I have to thank @Snogpitch for the scan. I just got my hands on one of these.
