I'm selling my JiffyDOS Commodore 64. And while it pains me to do so, I just don't have the time to use it, nor start a collection.
The C64 itself functions absolutely flawlessly, and switches between JiffyDOS and Basic with no problems.
It comes with its 1541 Disk Drive, Audio and Video cables, an unnamed PSU, and a particularly interesting and rare game called Heatwave, complete in the box with all the macguffins.
I'm using eBay to sell it, here's the link.
I will ship internationally, but you will have to pay actual shipping costs. The free shipping is for the U.S. only, unfortunately.
If you have any questions about it, don't hesitate to ask me here, PM me, or even send a message through eBay.
