I just bought 2 1M SIMM strips for my mac plus. Since they were the last two in stock ( I bought from a private party), one is a 100ns and 120ns. Now I see the fine print in TN 176 that says not to mix SIMM speeds in a row. This is quite unexpected and, frankly unbelievable. Having designed a microprocessor board with dynamic RAM way back in the dark ages, I can't imagine a reasonable technical justification. If there is one, can someone please explain it to me? And if the hardware does rely on this, what are tolerances? (i.e., what does "same speed" mean?) Thanks in advance... Chet Wood ~ (408)727-3357 arc!chet@apple.COM .
