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.
