I'd assume 0.5mhz -- I have a plain 8008 (not 8008-1).

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.
