Mark is correct, AOX does have a drop in 386SX board for the pc/at, however, when I contacted them concerning it (about three months ago) I was informed that they were only making the board available to OEM's and had no plans to sell it to end users. They also mentioned that Intel had expressed an interest in it. Price quoted was in th $700 - 800 range. If you follow up and discover that AOX has decided to make the board available after all please post an update. Noel -- Noel B.

Well, the quick and dirty answer is that the 386sx allows you to run 386 specific software that is becoming a little more prolific. For example, you could run windows/386 or the Desqview 386 utilities. The '386 architecture has quite a few extra commands and a more powerful mmu. It also has a mode that allows operating systems set up virtual 640k DOS sessions easily (I think Desqview takes advantage of this). What's the downside? It costs more to build a '386sx box than a '286 box because the chip generally costs more. By the way the '387sx is generally used in conjunction with '386sx and not the regular '387 because the '387 requires a bigger databus, like the '386 itself. Cheers, Ron P.S. if anyone finds a decent '386sx replacement module for the '286, let me know. I can't bear to scrap my current system, so will buy a new '386 or RISC box this year, but would love to upgrade anyway. | "This whole right brain, left brain thing is just a plot on the part | | of the humanities depart. to excuse their never having learned any science"| | Roger Dell, Prof. of Mathematics | | Ronald Woan, woan@cory.berkeley.edu | ------------------------------ From: woan@cory.Berkeley.EDU (Ronald S.

Another 1 M daughter board will cost $399 according to the ad. Anyway, I have been interested in upgrading my old Zenith and hope to get your opinions regrading my upgrade. Please help me. Now the questions are: (1) Is Inboard 386 PC compatible with my Zenith PC? I know someone posted a toll-free numbef for Intel Inboard support and wish to have that number so that I can call Intel to verify any myths/facts. If you tried Inboard on your Zenith PC, please let me know your luck or .... (2) Will my Zenith + Inboard 386 turn into an AT machine? I am wondering whether the additional 1 Meg is used for extended or not. I would like to run a large database and may need 1 Meg piggy board. The target software especially requires AT compatible with 1 Meg of exTended memory. I will summarize what I will receive to the net if there are such demands. Thank you in advance. ------------------------------ End of 80386 M/L ****************
