Yes it is possible. No have no pinouts/schematics. Wish I could find the website of the guy that used an old 286 mobo for exact same thing. In his case was easy IIRC because his board chipset was all socketed so he just removed all the chipset, ram, KB controller, rom, etc. (and maybe the crystals …
use old mainboard as backplain isa… pinout?
Posted on 2023-09-02, 23:53
I have an SBC that I should test but I don't have a backplain, since their price is not cheap, I thought I'd recycle an old 486 mainboard as a backplain by literally pulling all the pins except the power ones from the pin on the mainboard. Which pins should I keep in your opinion? clearly all those …
Re: IBM 386DX40...exists?

It almost seems that IBM wanted to switch from the 386 to the 486 as soon as possible by making the switch before the 386s were offered at their maximum speed and relegating the 386 file to budget computers with the SX chips. Yet the period in which the 386 was the fastest cpu I think lasted at …

This one… is the fastest “genuine” 486 ever made? By genuine you mean what exactly? 486 non pentium core is Am5x86, https://en.wikipedia.org/wiki/Am5x86 Intel stopped at DX4-100 (and others too). https://en.wikipedia.org/wiki/Cyrix_5x86 , was based on 686 design. Don't take this as canon though ;) …

Yes but it will be somewhat wasted (XT-IDE the card is designed for 8-bit slots after all), the controller is usually not the cause of size limits (especially if it's a traditional non-accelerated not-really-controller) and you can get better value by using only the XTIDE Universal Bios using a ROM …

and using a xt-cf card? can solve bypass totally the onboard controller of the ps/2 (286) and ps/1 (386)? can allow me to use a 1gb cf card? (the maximum the pc330 dx4 486 can see).
