( My apologies to those who have seen a previous article on this
subject in another group, but I received no reply to that posting. If
you know the answer to this, and can't stand the thought of a
smoke-belching mac, please let me know soon...)
I recently purchased 2 SIMM strips from a private party. One of them
is marked 100ns and the other is 120ns. Naturally, I then read the
directions (TN176), and discovered much to my surprise that Apple
specifies that both SIMMS is a row have to be the "same speed."
I had assumed that fast enough would be fast enough, and having
designed hardware myself in the dark ages ( I even designed a board
using dynamic rams,) I can't figure out why there would be such a
restriction.
If anyone can explain why this would be, within the next couple of
days, I could be convinced to try to swap one of my SIMMS. Otherwise,
I'll just find out empirically. (Stand back!)
Thanks
