The reason you want the system ROM in 32-bit fast RAM is that it will increase your screen performance dramatically! Your normal screen IO is being handled with ROM running at 16-bit speeds; that redirected to 32-bit FAST RAM will turbo charge your display. I was shocked at the difference in screen updates. I would suggest 4 megs of 32-bit RAM, that will give you enuf to work with most images at 640X480 max (there are some that are too large, mainly due to large amounts of colors), and leave you some space to push your system ROM into RAM for that extra performance boost. I'm not sure, but I believe on the CSA board you can only have it config with either 2, 4, or 8 megs of RAM. 2 megs of RAM is fine, only if you have conventional memory available to you (ie: another memory card). Most folks don't, therefore I'd recomend 4 megs. You should really buy as much memory as you can afford. (And as large a hard drive as you can afford). When talking about memory, accellerators, etc you're bound to get differing stories. That's because different people have different applications, and desires in mind (and some may have other motives in mind, ie: a sales commission if your talking to a salesman). What is it that you are confused about? Is it getting so much memory? Whether or not to get a MMU 030 or a 030 without a MMU (Shall I call it a 030SX :->)? Or getting the CSA board as opposed to an alternate solution.
