[Vic 20 memory]

Yes...I did have problems with the 16K files. But....Wow...this...now it works as two independent 8K blocks that can be assigned to Blocks 1,2,3 or 5. Printing a case now. I saw posts about the VIC-1110 8K modification and adding switches to the VIC -1111  16K  but no details....didn't think it would be this straight forward. In this picture its set for 8K to Block 2 ($4000) and 8K to block 1 ($2000).

 

Any 3K options/additions with this? Still looking through OLD posts, lots of references to long gone pictures.

So, weekend warrior on this but had recently gotten a VIC 20 and with limitation using the SD2IEC as far as loading game cartridges I found a VIC-1111 16K RAM Cartridge. When searching online in 2021, I could only find a picture of an opened but already modded 8K expansion cartridge. Below is the picture of my VIC-1111 16K RAM...as I see it, the 4 pads on to the right middle top of cartridge must the ones that are dipped switched on the 8K version; the red arrow points to the pad that is default jumpered (removed in this picture) on the 16K version (VIC-1111) and the green arrow shows where to jumper (pad/switch 1) for cartridge loading ($A000 RAM/ROM cartridge space). 

 

I had been been loading the cartridge images into basic memory. Now it works fine. When you change this, the space available for basic is once again 3583 bytes, so you have to use FB20 (commodore file browser) not FB20-8K. Then once loaded type "sys 64802" as above to start the game. 

 

I'm still working through the games, so likely to have some issues pop up with the 16K games I guess.
