The 286/386SX/486SLC could address 16MB, the full 24 bit address space. > the ISA bus was only 16-bits wide, which limited the utility of the 32-bit bus for fast graphics transfers. Not only that, it was 8MHz to match the speed of the fastest IBM AT. VLB on a 486/33 or 66 ran at 33 MHz and was a godsend, 8x the bandwidth of 16-bit ISA. |
