VLB does work on a pure 386 CPU. I had a board based on OPTI495SX that did it. However, it wasn't a whole lot faster than ISA, and only certain cards would function with it (ATi Mach64 was one of them). I have also seen Trident, Cirrus Logic and Tseng cards that have jumpers for 386/486 mode. Hell, I've even seen a 386SX board with VLB slots (used an ALD chipset), and Alaris made 16-bit 486SLC motherboards with VLB slots too....I think that was using an OPTi 295 chipset. What it all comes down to is how much effort was made by the chipset vendor and board designer to get it working.

I just built maybe a fastet 386sx, and isnt based on 486 SXLC - SLC, its an ALi M1386SX 40MHz, 128K L1 cache and VLB!

Nice built. Speedsys shows the great vesa thruput. Is nearly double as on my overclocked SX with your ~ 11500kb/s.

Would be interesting to see yours compared to an IBM 386SLC which is more or less a 386sx with internal! cache.
