The 80 would mean 80ns which is more than fast enough. The other part doesn't
tell me
enough and doesn't mention the whether it's DIP, ZIP, whatever
Here's what the CVT manual has on it
"The memory chips used to populate the GS Memory Board are 1Mb x 1 DRAM memory
chips in a DIP package. The memory chips must be rated with an access speed of
120ns or
faster."
If you want I can email you a PDF of the manual, such as it is. I'd just need
to know which
version you have
