- I am seriously thinking about getting a high-end 486 system; however, the Local Bus
- hype has me a little worried. Many reviewers regard it as the best thing since sliced bread,
- but many competent dealers I have talked to told me to stay away from Local Bus sytems at this point in time,
- even though they are selling such systems themselves. The so called VESA Standard seems
- to contain a lot of lose ends (and few people have actually seen the specs).
-
- Here is my concrete question. I have heard the VESA Standard specifies the clock to be max. 40Mhz.
- On the other hand a lot of machines are advertised as true (486DX-50) 50Mhz machines with
- VESA Local Bus. Do they just run the Local Bus at a higher than spec frequency, or do they half the clock?
- Many of the big mailorder houses sell 486DX-33 or 486DX2-66 machines with Local Bus, but no 486DX-50.
- Is the potential incompatibility at 50Mhz the reason they don't offer such systems?
- Anybody out there who knows what's going on?
