More specifically, I am comparing between the SIMMS/SIPPS used by 32 bit Amiga system against the 030 Macs or 386's. From what I know, they can get perfectly reasonable performance by using the normal 70/80ns 1x8 SIMMS which are CHEAP, but why the heck does all 32bit Amiga uses more expensive chips? Is it not possible to design them to use the standard SIMMS, like what 386's use ? A guy who owns Mac SE/30 claims that you can get 32bit fetches from memory by arranging the 1x8 SIMMS appropriately.... Any explanations would be appreciated. +-----------------------------------------------------------+-------------+ | Yeo-Hoon Bae tinyguy@homer.cs.mcgill.ca | Amiga /// | | Dept.
