Greetings, I am interested in buying the CSA 68020/68881 External board and am trying to get in contact with any or all people who have it or have worked with it. I need to know things like: How fast is the systems? How Software/Hardware compatible is it? Did you use the internal (7Mhz) or external (14Mhz) board? Anything I should watch out for? Thanks. Any comments are welcome. Todd Weiss Triangle Business Systems

I had one for a while. Unless you are mainly concerned with speeding up floating point, DONT get it without the 32 bit wide fast ram. I had one w/o it, and running flight simulator (very integer arithmetic intensive), with the cache enabled, only got a 2% speedup. This was with one of the old 14mhz internal boards. As an aside, has anyone out there run FS on a 68020 machine with the 32 bit RAM? How much smoother did the graphics look? I made sure that it would work with one.

2% Speedup!!! Jeez. Well, I ain't gonna spend $1500 for 2 lousy percent! They sell a 512K static board (I assume it's 32 bits wide) but it costs another $1500 bucks and I ain't gonna spend $1500 bucks for 512K!!! Oh well, CSA claims a 1000% speedup. Somehow, somethings gotta be going on here. Any more is appreciated. Thanks again. Todd Weiss Triangle Business Systems
