- Update! This tester is now discontinued and will, in the next 4 to 6
weeks, be replaced by a newer model. If you're intending to purchase
this tester in the coming weeks I strongly recommend you wait until the
new version is released.
NeoLoch's original budget RAM IC tester, the LCD tester adds
additional RAM tests and more information on each test completed.
Built in 1A voltage regulator, on / off switch, DC power
jack, and a new layout that makes testing a breeze.
you have a PICKit 3 (or compatible programmer) you can
write your own code to use the tester for your specific needs. The
programming port is located above the MCU socket. Code examples for
using the LCD and sampling the switches is included in the datasheet.

NeoLoch will, from time to time, release new firmware versions that
will add new features and correct any reported bugs. This firmware
update will be available in the form of a programmed MCU you can
purchase to replace the existing MCU in the tester and also as a
download available from this page for those that have access to a PIC
4th, 2015 - 2114 & 6514 RAM ICs are no longer on the official
testable list. We've just discovered that some
and 6514 RAM ICs will test bad even though they are good. For this
reason, the 2114 and 6514 RAM ICs are no longer officially supported by
