professionally hand-assembled and tested EPROM Emulator.And most importantly it's all open source so you can build it yourself, and for those who don't want to DIY - you can get a ready-made device.Ī detailed description on my website: MyGeekyHobby-EPROM-Emulator I just took some of my personal experiences, created a simple to understand architecture, used off-the-shelf components (no GAL or CPLD) with nothing that would require sophisticated tools to test or implement. It's not a new topic, similar projects have been published in electronics magazines many times. It's a must-have for anyone dealing with those old platforms, testing different 'loads' or writing low-level code. This type of tool used to be very popular (and essential) in the days of 8-bit computers (think of you commodore, atari, zx spectrum etc.) It was the fastest way to develop a firmware.
You can plug it into your computer and 'upload' a new version of code in seconds (instead of removing, UV erasing, reprogramming, and re-installing a traditional EPROM chip). EPROM Emulator is a tool that can temporarily replace an EPROM memory chip inside your 'target' device.
