Anyone need 486 motherboards?

Hmmm, are you sure about this?

A 'real' DX-50 will clean the clock of a DX2-66, due to the true 50 Mhz bus.

If your seeing a DX2-66 beat a DX-50, then the DX-50 is not being run at
full (local bus) speed.

I've got a (large) pile of NEC EISA servers that take plug-in CPU cards,
so its easy to swap between
the DX2-66 and DX-50 while keeping the same BIOS and chipset. The DX-50
is clearly faster.

(I'd love to not have this pile of servers, NEC PowerMate Express A7x's,
in both desktop and tower chassis)
