Finally I will give my 286 a proper house. This one:

I'm trying to identify the homeless in this thread: http://www.vcfed.org/forum/showthrea...this-286-board
The specs:
* 286@12Mhz NMOS Intel processor
* 2MB of RAM (1MB in 80ns DIPs and another one in 256KB 70ns SIMMs). An AMD CMOS 287@10Mhz
* SUNTAC chipset. AFAIK this chipset can work in EMS or Extended memory memory but you cannot have both types of memory. I've configured mine in EMS mode which IMHO it's much more useful on a 286.
* Acer M5105 super I/O chip. It has a 2 COM ports, 1 LPT, 1 floppy and 1 IDE.
These are the cards:

For the OSs I intend to multiboot PC DOS, MS-DOS 3.30 and an DR DOS 3.40 or older if I can find it
I intend to show my progress with this build, get new ideas and ask questions in this thread.
Thanks a lot to everybody
