I've reached out to Innovations earlier this week to check the price of a memory tester for testing 30-pin Mac SIMMs. To my surprise, I got a reply that they've permanently closing due to COVID.
I've been having random issues with ram, and it's hard to tell if the Mac's are being too picky or if the ram is actually malfunctioning. To my surprise, there is no one else that makes any hardware to directly test SIMMs. There was a device called CST SP3000, but they also have gone out of business.
I somewhat expected for there to be an adaptor for a TL866II with the capability to test ram modules but that just doesn't exist. You can use the TL866II to test individual DIP chips, but not the RAM module as a whole.
Anyone have any suggestions on how to run an extensive test on 30-pin SIMMs? I recall that one of the Boot Utilities disks had a RAM check, but not sure which one. The ram check Mac's perform during boot doesn't seem sufficient to catch bad or incompatible RAM. We can see this from when we try to use a 3 chip SIMM module; it will boot up but shortly after when launching any application the system will crash.
