It took me a while, but I finally allocated some time to allow creating a video to demonstrate the usage of our TL866 EPROM Programmer Adapter for 27C400/800/160 and 27C322 16bit EPROMS.
If you’d like one of these Adapters, you’ll find a Kitset or a Fully Assembled & Tested option, on Tindie: https://www.tindie.com/stores/DigicoolThings/
Note: We no longer sell on eBay, as their high fees and forced mutiple exchange rate conversions (with exhorbitant fees), meant it was no longer financially viable to offer via eBay.
The video includes a brief introduction, followed by backing-up a 8Mibit FLASH ROM from a Sega game cartridge. Finally, writing a 27C322, the largest 32Mibit MASK ROM pin-out compatible 42 pin EPROM.
