The Rs value is dependent on your X-tal; you'll need it only if yor
X-tal gets overdriven. Look at the signal with an oscilloscope and if
it's distorted try 100R (or higher) until you get an nice sinewave.
Then decrease the resistor value until you get back the distortion.
The correct Rs value should be somewhere in the middle.

Oops, I meant to say that I was looking for the resistor value for a 20MHz
crystal for my 16c64.

Nope, I haven't heard of any other EEPROM products, but it sure would be nice
if they produced one with more memory.

Yours,

Such things are being discussed, but nothing's out yet (any or all of
the options above) - what do you want (and how many?)?

1) No, or at least not yet. Eventual progression of the 16C84 to
  0.9u/6" wafer process will allow this, but not before mid 1995.
2) It is
