i used to have two et4000ax cards, one generic and one everex vram, but both are from year 1990 without 0wait mode or hicolor ramdac.
and now, i finally got another et4000ax with both 0wait mode and truecolor ramdac. while its not the fastest isa card due to lacking bitblt(w32i is much better but still could not match the cirrus5434 and mach64vram), it was so influencial that its worth remembering.
