i wasn't supposed to get a 286 board because i didn't know what i can do with it: no 32bit protected mode, no programs for win95, and even in win3.1 there were many programs that demand 386 enhanced mode, accessing over 640kb of ram is inconvenient and slow if possible. but at last i did simply because the board "looks good".
its very similar to this one, except that it has 4 simm slots in the place of the sipp slots:

it has a harris286-20 cpu which is second only to the 25mhz model, but with a crystal of 32mhz, which means it would only run at 16mhz. it has a headland ht12p-16/a chipset which supports ems-emulation, but does that "16" indicate that its rated for up to 16mhz only? i had the idea of swapping in a crystal of 40mhz but remained doubtful on this, also it has a very old version of ami bios with only one page of options and no switchable isa clock so the idea is turned down.
now back to my puzzles:
what can i run on this with 4mb of ram? more than those that can run with 640kb on a 8088.
is support for ems-emulation important if i am looking for another 20mhz-capable board?
is installing a 287 fpu helpful?
