Vintage DRAM Tester for 15 different RAM Types
Fast – Precise – Open for many 8-/16-bit systems like C64, C128, Amigas, Atari 800XL, 1040ST and others, Apple IIe, Spectrum and many more
What this project is
A fast, open-source DIY DRAM tester for vintage RAM chips used in C64, Amiga, Atari, and other retro computers. Built around an ATmega328P on a custom PCB, it tests memory thoroughly in seconds and supports a wide range of chip types with optional OLED feedback.
Why this tester?
Most Arduino-based DRAM testers need up to 2 mins or even more for a single 41256 RAM and check only basic functions. This project completes a full memory, address, data-line and retention time test in 15 s or less (or even 2.5 s faster without the display). It is probably the fastest Arduino solution which also covers static-column DRAMs, cell retention time and 20-pin ZIP packages.
