I have just been given an old IBM PS2 machine without a mouse.
When I first plugged it in I got a windows 3.1 dialogue box.
I could not shut it down properly so I swithched off.
I plugged in a mouse, probably not a ps2 mouse, and switched on but now all I get on the scrren is :-
I see it counting up to 8064 Kb ok it does this twice then puts up the number 305 which I assume is an error code gives 2 beeps , clears the screen and then writes 305 = " draws a red circle with OK in it but a line thru it" and an arrow pointing to a representation of some pages of paper with IBM written on them.
It will not respond to the keyboard nor the mouse--I now have a ps2 mouse connected but it makes no difference.
Can any body suggest what to do? Thanks Keith
