Sounds like you have things well-in-hand, Joe! (Just curious, have you changed any caps on either board yet?) - OGM While I'm not a fan of gratuitously replacing the caps I've had two boards now that have suffered "delayed booting" because the cap in the reset circuit was defective. Have ...

I'm really looking forward to playing this, it looks a real cracker.

I've generated a Final Expansion loader file, if you add this to the .d64 named "LOADER" then it's easy to run it on the FE3, including burning it to flash.

Cheers

I would opt for a newer "CR"-model with the 7-pin DIN-plug for power as then you can use C64-power supplies as well. Having had two C64 PSUs die on me this week I would not recommend a CR model. While the original model does run a bit hot the transformers are bullet-proof. You can always ...

The Vic-20 was the first computer I ever owned back when it originally released. I've been looking into getting one recently. However, I've looked on Ebay and the quality of the cases is pretty poor which is understandable for a device that is over 40 years old. I'm also slightly put off by the fac...

There's an appendix in the User Guide I wrote. The code in VICE is also a useful reference.

I came across this design which replaces the voltage conversion stage in the old wedge-shaped PSUs

Thank you very much.

Thanks for doing this. Is there any chance you can produce an SVF file that is compatible with OpenOCD?

Not that I'm aware of. I keep toying with the idea of building a batch, but I'm the wrong side of the Atlantic for you.

Glad to see you back. Will follow with interest.

The Final Expansion 3 card has a super ROM mode that does this.

Edit: I missed you want to bank $A000 and $B000 separately. The FE3 can't do this.

Can you post your cart setup code?

Hi. I have a VIC 20 CR board with a bodge wire on the back that appears to connect the audio pin of the VIC chip to pin Y on the expansion port via a 1K resistor. What does this actually do? Are there any cartidges that use this? Do you have a picture? Somewhere I've seen a schematic this this labe...

I assume you've isolated the keyboard as a cause by trying to switch by software?
Check continuity on A11 between the character ROM socket and the 74LS245.
