- Whoops,
-
- Michael caught my misleading statement. I never meant to quote Intel
- as saying the 386sx was a glorified 286. I meant to say that the 486sx
- was a 486dx less the coprocessor according to Intel. And now I know that
- the 386sx is NOT a glorified 286. I was told that by someone who I obvious
- just took at face value. But now that I'm on the subject, there is a PC
- here at work (IBM model PS/2 386/70) that is so slow when it comes to
- windows applications, it makes me wonder how this machine could have
- been released. When I want to run EXTREMELY small Excel data plots, access
- the hard drive, anything but input data to the screen, there are very
- irritating delays. Now, I'm not a computer speed demon, but it seems like
- I trip over myself using this machine. Does anyone know what the deal with
- this machine is? Since I'm in the market for a 486 machine, I do not want
- to get a new machine and run into a similar problem.
