Keep an eye out for the Bug Trap Dynamic Ram tester then, it will check those from around 250 ns to 80ns. I use it regularly... John :-#)#
I'd certainly like to see 4116 and 4164 at needd Williams game speed being able to be tested.

How is the project going?
Speed of testing seems to be the biggest issue as many RAMs will work fine under slow testing but when run at their rated speed they then fail.
I've been thinking about this RAM tester for the past number of years and was wondering which RAM people would like to be able to test.
For example, my needs are to be able to test 2114, and 5101 ram as I have dynamic testers for the others and a couple of static ram testers for later RAM.
Soooo I'm thinking more in line of a simple free standing circuit board that one can plug these into and with an adjustable calibrated speed control, much like the StarTek Dynamic Ram tester from the early 90's. The schematic for this is on the web site...
One other project involves making a socket that I can drop into one of my old dynamic RAM testers (Bug Trap's late 70's unit) and see if I can fool it into testing the 4-bit static RAMs.

Gentleman !
I'm facing a problem building the software that makes the pattern test. I only have Windows XP machines, and the way that this OS works on Parallel port is pretty different than the Windows 9x version. (Thanks to Microsoft !!!)
On the Christmas holidays, my wife forced me to paint my house... Ohhh yes... you see right... And as I'm very busy on my job, I just have holidays to work on my hobbies.
Is Carnaval in Brazil next week, and I'll try to make this software during theses days - Yes man... I'll trade the Carnaval by build one test Pattern Software for you guys ;)
ANY HELP AND COMMENTS IS APPRECIATED !!!
I'll keep you guys up to speed.
Take care,
