JiffyDOS Production Unit

After many months of preparation, JiffyDOS production ROM overlays are finally ready for distribution. The system utilizes the ROM-el FLASH-based ROM emulator, allowing the units to be fully assembled before programming.  Units should be available shortly for sale in the online store.  Click on the picture for a larger view.

Based on a customer request, I’ve designed a small adapter card that will allow C64 cartridges to be used in the Commodore VIC-20. The design is not finished, and suggestions are appreciated. Switches allow the IO and BLK select lines to be configured per cartridge. Barring any major changes to the design, I hope to have units available early 2010.

I tried a few, but decided this one was simple enough to meet my needs, yet flexible enough for the items I have to sell. I hope to add my full inventory over the next few weeks.
