I have a one, designed by Charles (?) Cook, and first
implemented by John Molnar, which I've reimplemented
for the Sol, some Z-80-based machines, and the 8051
embedded systems I've developed. But I never got around
to porting it to DOS...

Our Dell servers shipped with a program called "Dell
Diagnostics" which includes a comprehensive memory
test that can check for stuck bits, shorts between
address bits, short between address and data bits,
etc.

It complains when I run it on non-Dell equipment,
but usually works, and it's so far caught problems
nothing else would catch.
