WTB: Amiga 2000 486 Bridgeboard

[Zac67]

There are no 486 class bridgeboards or even Pentium ones. Period.

The best you can get are 386SX class boards (16 bit bus). Many can be upgraded with a 486SLC but that's far below a 386DX or even a 486. It's got a 486 instruction set (no FPU), a small cache and is faster than the 386SX but that's dog slow anyway.

If you abandon the 'bridge' concept you can use most CPU boards intended for passive backplanes - you'll have a completely separated PC running inside your Amiga and have to provide the communication yourself (NICs, serial/parallel, whatever).

I've run a 100 MHz Pentium board in my 3000 for a while but it failed to make a point with an Athlon Thunderbird sitting right next to it.

Compaq 386 also stands for the first 386 PC made, which i believe was running a 386 sx 16 MHz.

Nope - the DX predates the SX by several years(!) and started out as low as 12 MHz. The first common machines were 16 MHz though IIRC. The SX was added to increase 386 software support by enabling entry level systems.
