- Is the 486 a 32 bit bus computer????
-
- If so what is the difference between the busses?? ISA and EISA???
-
- Will it make a lot of difference if I purchase the ISA instead of the EISA
- bus???

- Thanx
- Confused ????

- ----------
- The 486 is a microprocessor with 32 data paths internally and to memory.
- The ISA bus is a 16 bit I/O bus. The EISA bus is a 32 bit I/O bus which,
- in addition to supporting ISA I/O cards, supports a 33 Mbyte/sec burst
- mode. Computer manufacturers build 486 computers with either ISA or EISA
- busses. As has been pointed out, a single user will not notice much
- difference between 486 ISA and EISA machines, everything else being equal,
- especially if the video controller is on a "local bus".
