4164/41256 DRAM Memory Tester for Commodore 64 C64 and others! [NEW]

Description

4164 / 41256 DRAM Tester
for Commodore and others!
Do you have questionable DRAM that you're not sure is good or bad? This tester will help you sort through all that. You'll quickly find out if any of your DRAM chips are bad.
The DRAM tester at its core, utilizes an ATMEGA328P with an Arduino boot loader which means the firmware is written in C.
The construction is such that the ATMEGA328P is socketed so it can be easily removed for firmware updates.
The coolest part about this tester has to be the OLED screen. This gives you a very nice read out of the testing progress. If the tester discovers that a chip is bad it will even display where it found the probem.
You can test both 4164 and 41256 DRAM. Simply move the jumper accordingly. 1-2 for 4164 and 2-3 for 41256.
The DRAM tester is assembled here in the US in Florida. I build these myself. They are not mass produced. Each tester is fully tested and carefully packaged before being shipped out.
