CAPS0ff writes: In a previous post we described some early attempts to analyze the Taito C-Chip. See Haze’s forum post for some background on the C-Chip itself. In particular we’re interested in the EPROM. Previous efforts focused on less invasive techniques with the goal of keeping the C-Chip alive after dumping. Unfortunately, we’ve been unable […]

Arduino Mega EPROM programmer
An Arduino Mega Eprom Programmer project from Robson Couto, that is available on github: Recently, I acquired a SNES, but it only came with a bootleg Mortal Kombat cartridge. In my search for additional games, I stumbled upon a growing trend of repro cartridges being sold on various second-hand websites. These cartridges, which often have […]
From the comments: EPROM Programmer
Chuck shares his experience programming 1702 EPROMs for the 8008 with an Pro-Log M900 EPROM Programmer: I thought I’d share a little known thing about [the 1702 EPROM]. When you erase most eproms they go to FF and the the process of programming discharges the bits that you want to be ’0′ The 1702 worked […]
Programmable memory guide
EPROMs are old-school data storage chips with a little window that exposes the silicon inside. Once these chips are programmed, they can only be erased by shining ultraviolet light through the window. The EPROM help page is a guide to identifying and working with these devices. It also covers more modern programmable memory like EEPROM, […]
