Building an Epyx FastLoad Cartridge & Finding MORE AliExpress Faked Chips! SD2IEC SPEED TEST!

This video is kindly sponsored by PCBWay – https://www.PCBWay.com​ and we’re making an Epyx FastLoad Cartridge for the Commodore 64 8 bit microcomputer! We do a full build of the project from PCBWay, including EPROM programming with my Minipro.

We discover that the EPROMs I was sold by AliExpress are fake chips, having been skimmed and remarked by the seller, so we find a way around that issue. Finally we perform a Speed Test between an SD2IEC with and without the Epyx Fastload cartridge and see if it makes a difference!
