That seems rather low, too. I also get a score of 23 on my Compaq DeskPro 286/12. Could be they ran without the cache enabled as well? BTW, your 80286 is 8 MHz as evidenced by the 16 MHz crystal and benchmark results, not 6 MHz as you labeled it. Not a big deal, I wasn't sure you were aware of it or not.

Hello, you are wright - it sould say amd286-8mhz. :)

..i had to build some socket extensions , but after i firm pressure the Nokia-module did connect to the motherboard ;)

The speed of this "new" (a call it new - i have never used it before :D ) nokia-module is not doubled. But the feeling , when used in PCDOS is better then the MakeIt486 (without cache enabled) !!

I guess this further supports the assertion that a 386sx really isn't any faster than a 286 at the same clock speed. The 486 is really hurt by the lack of cache. Even that early on it's obvious how important it was to keep the CPU fed.

There's always babyAT motherboards. I dropped one into my XT clone back in the day. A tight fit under the A: drive housing, but it worked well.

When going through my stack of boards I happened to find a board that has a 386SX: not soldered but using a socket. Because this board was not of the usual AT format, wrong placed holes and LPT/COM port at the end of board, plus it needed a not-standard riser board to attach cards, which I didn't have, so I decided to use this CPU for my project. To be honest I never paid that much attention to the pins but now I see that they are small, IMHO really to small to solder them using a normal soldering tool :(
Just another challenge, I think....
