Hi Guys,
Just a follow up, for anyone curious.
Stewart and I tried placing a mixture of 4164 and 4264 chips into the Apple IIe
and they both worked equally well.
What ever differences there are in these chips is buried in the data sheets,
but for this particular machine they don't matter.
Furthermore, the RAM TEST function works on the memory on the 80column card
first.
That is to say, if you have a bad chip on the mother board AND on the 80 column
card, only the chip in the 80 column card will be reported.
As you may already know, it's always best to remove all cards and start the
testing on the base system, then add cards and test as you go along.
Cheers,
Josh

I'm not sure, but I'll look to see if I have a 4264... strange sounding
chip number. Does it go by any other number?
4464's are 64K by 4 bits, so is the 4264 a 64K by 2 bits?
