Since it doesn't have the VLB slot, it's not terribly interesting as a hybrid system. It would probably work better as a 386. As it was a budget board, at best it would be a low end 486...which really needs a 32-bit bus for video anyway.

Well you can always solder in the 32bit extension. That board looks like it has cache too. I was thinking slapping a 386 into it anyway, or just ditching it since I have a bunch of 386 systems anyway.

I think I have the same board, but mine says FX3000 not FX30000. It had the same non-populated VESA bus slot, but I soldered one in to see if it worked and ended up burning up an old Cyrix VLB card. I guess it isn't really a VESA slot. Anyway, I run a 486DLC-33 and IIT 4C87DLC-40 at 40Mhz currently with an ATI MACH32 ISA video card in it and running the ISA bus at 40/3 (13.33MHz). This allows it to run DOOM2 reasonably well. Plus I have the ability to try all sorts of 386's up to a full blown 486DX-33 in it. The only drawback is having to have several clock oscillators on hand. Plus it has a full 256K cache on it instead of the more common 128K.

It should be a VLB slot. Perhaps there were some support components that you forgot to solder on with it.

You know how many issues VESA bus has... Perhaps it was planned on the board but when it came to testing the prototype failed and the manufacturer had a lot of empty boards shipped already, so they never soldered any VLB slots on them?

Yeah, I think RacoonRider is right. After I burned up my Cirrus (not Cyrix like I first posted, had Cyrix on the brain when I wrote it) I checked the signal/power pinout on the socket. It is not the same as the VESA VLB standard, some of the pinout is but the important power pins are not. They maybe put it there before the standard was finalized?

Good to know, I won't bother with the mod then. Will try installing a 386 next week and see if it even works. Not sure which speed oscillator it has.
