When upgrading the 464plus to 128K, do 150ns 41464 chips work (as in the old CPC) or does it really require 120ns as fitted in the plus?
I didn't think access was required to be any faster than 250ns, to be honest.
I would appreciate it if someone knows... :)
Yes you can put 150ns, as some PLUS use that.
But, the best is to add sockets in case of it was not good to mix them.
Excellent, thanks! :D
150s are fine and mixing 120s with 150s is also fine.
