For technicians maintaining legacy industrial control systems or other hardware to the retro-computing enthusiasts, the RAMCHECK INN-8668-2-A 30 & 72pin SIMM Adapter<\/b> is the holy grail of diagnostic hardware LOL, Not Really holy grail but highly sought after. This adapter is Capable of testing both 30-pin and 72-pin SIMM modules, this rare adapter is essential for verifying legacy (Vintage) RAM, but acquiring one today is a major hurdle. Single Adapters are virtually unobtainable, typically locked behind complete RAMCHECK bundles (As This Was) These bundles are priced anywhere from $1000 to $1,500 or More.<\/p>\n

Don’t Forget to See My RamCheck Teardown, Firmware and Software Archive<\/a><\/p>\n

Ramcheck is No Longer in Business they no longer sell these so To bridge this gap for the repair community, I am taking a complete hardware reverse-engineering approach tracing the pinouts, X-rays help with that I will be creating a modern open reproduction adapter.<\/p>\n
