- Well, I looked at the literature and considered it for my model 80-071 and
- decided to go with AOX. BTW Kingston just anounced a similar board but
- somewhat cheaper.
-
- The reason I'm getting the AOX is the recent price reduction. The 486-33DX
- is now $1095 (education price) Last time I checked it was $2700! AND the
- fact that it has on board memory of up to 16MB. THe Sigma is $925 and is
- stuck with the memory on the bus. Even though this may be 80ns I've been
- told this acts like 300ns becuase of the bus.
-
- AOX is a busmaster board. The original 386 is utilized for I/O. The AOX
- memory can be accessed by other busmasters and the original 386. Its
- compatible with OS/2.
-
- I think the performance on the AOX will be much higher than the SIGMA or
- Kingston for that matter.
-
- AOX wants $285 for 8MB SIMMS.
