Random ramblings...
Has anyone created a test for these CMOS RAMs? I am not very good at
programming and it would be useful to have this.
The only other way I can think to make a valid test is to make an
adapter that holds a second 5101 that fits onthe5101 under test and run
all the lines except the data in parallel - have a jumper that takes the
extra 4 data lines over to a Eprom/ROM using a glomper clip.
However a proper software test would be more elegant...yet the glomper
easier to make up! If I can find a 22 pin version that is, or simply
bend out the data lines and wedge the5101 onto the one on the
board...hmm, that does sound easier, then one can use the built-in
Fluke RAM test.
I'll let you know if the glomper test gizmo works - have a couple of
irritating Williams boards to try this on.
