Joe, You might be referring to the Ming Microsystems HT-28 IC tester. They are now Rayming Corp, and apparently no longer make the tester.
From one of their ads:
"The Data Genie HT-28 is a convenient way of testing Logic ICís and DRAMís Tests most TTL 74, CMOS 40145 and DRAMís 414000,44164 -441 000 ICíS. The HT-28 can also identify Logic Kís when a non-standard part number is used or if the product ID has been removed. The HT-28 is compact in size, 6-W 6îx4-5/16îx 2-t/8î, and can be operated from an AC adaptor or up to 600 hours on 4-ìAAî alkaline batteries." Joe wrote:
In about 1985 I remember seeing a PC based IC tester that someone was making. IIRC it tested CMOS, TTL and memory ICs and had a disk based library of IC functions. The nice thing about it was that you could add new functions (IC definitions) to the library. It would also try to identify unknown ICs by comparing them to the functions in the library. I can't remember who made the thing but it was a small company and I THINK they were based here in Orlando. I've been wondering for years what ever became of them and their testers. Does anyone remember who they were or what happened to them? I THINK the tester was just a socket hung on the end of a ribbon cable and that it used a 1/2 length adapter board inside the PC. The whole thing looked about like one of the PC=based EPROM burners.

The Fluke can test these but it has a couple of issues, namely speed, as it is not able to test these at fully rated speeds.
It also would be nice if someone would develop a cyclic testing of these.

Can someone recommend a descent RAM tester for testing 4116's, 2101's, 2114's, etc. (Basically your typical video game/pinball rams)
