It works from a mini USB (not included) connected to 5 volts. This unit will transform the voltage into the required 5, -5 and 12 volts for the unit to operate and will test each address of the RAM. If each address returns no errors the RAM will show as being good. You can also run a stress test which will continue the test indefinitely until it is manually stopped.

I have several vintage Commodore PET computers that I am upgrading. I saw an article about modifying 4164 (64K) chips to work as 4116 (16K) chips. I wanted to try this and needed some way to test them. I purchased this device and it tested my chip with modification - and it tested good! This is a great tool for vintage computer enthusiasts for systems with 6502 processors that need RAM upgrades and want to try test 4116 memory chips. Very similar to memtest for x86 windows based PCs. I have a plethora of chips and now I can test them with confidence.
