Do you know if these where for any accelerator card with a 286 chip? Also is it possible to upgrade it even more? 586?

AFAIK the Atonce have 80286 8mhz onboard that is enough to run windows 3.1 (not 3.11 !!) with other boards using 8086/8088 compatible processors you can use windows 3.0 (latest version to support xt hardware/real mode operation)

I don't think that 486SX can be used on 286 based motherboard. I think it is the 486SLC produced by Cyrix that was an upgraded 386SX (witch has an external 16bit bus to be used on 286 based boards). The 486SX is a 486DX without math processor.

I had an old 286, don't remember the specs, but it had ms-dos 6.22 and windows 3.1 installed. Not much use for windows back then..
I once tried installing windoze 95 on a 386/16Mhz, way to slow, could not use it for anything :lol:

My (crappy) 486sx laptop with 16mb ram runs win95 fairly.

afaik the ad ons for the 500 which I had one(vortex at-once plus 286) at one point was for 286 compatible software and it was capable of installing ms-dos (9.11) or what ever, also the old radioshack/tandy comp Os.

it did flicker abit as it ran hot and eventually locked up the system from overheating

pc-task 4.x was a better solution but being software based, it was slow and needed at least a 030, I never got it going on my 1200T 060, as it wouldn't default to my drive for whatever reason, but i did install win95 on my sx-32pro 030 which ran sloooow, but did do win applications, and could boot some games, again slooow

The only ones I know about were for 286 to 486 and then only the square chips.

I tried PC Task on an A1200 and as ziphoid said is was so sloooooow that I soon took it of again. As already said get yourself a cheap PeeCee.

You may be right on that.  I'll have to check when I get home from work.  Do know the manufacturer CLAIMED it was a 486.  However, like you pointed out, the Cyrix was just a souped up 386.

Still, it'd be better than a kick in the head!

Got around to checking the 286 to 486.  It's a  TI486SLC, so we're looking at a 486 in 386 clothing.
