Ok. I'm assuming they can work together then? I have scoured the net and found a
couple of pics of mark-8 boards with a mix of 1101a and 1101a1.. or maybe thats why they
werent working? :)

I have some C1101A RAMs I was planning to use in my Mark-8 project. I'm
having trouble finding more, as previously mentioned because the price has
shot up so much. I'm wondering, I'm finding lots of P1101A1 RAMs with the
correct date codes.. are those compatible with C1101A/P1101A? I don't
understand what the 1 at the end signifies.
According to my TI manual the 1101A is 1500 ns while the A1 is
1000 ns.
