Dosbox has basically unlimited bus speed, too, so you're not getting the delay from writing to a real VGA.

- aidenn0 4y agoThough as long as your 286 was 8MHz or greater, that speed would be the same on any 386 (or 486 lacking a VL or PCI bus), I don't think PCs with ISA running faster than 8.33MHz were common.
- dragonwriter 4y agoBoth the 286 and 386 PS/2s on which VGA was introduced had 10MHz bus speed, not 8.
- actionfromafar 4y agoI want to say I have seen 16MHz ISA bus somewhere but that in reality you could not use any ISA cards except some VGA cards at that speed.
- hakfoo 4y agoXT class machines generally kept the bud speed coupled with the CPU speed; 10MHz and the very occasional 12MHz one are out there. I'd suspect they might be finicky about expansion cards that expect to be ran no faster than 8MHz.
