Hi everyone.
After installing an Intel 8087 in my IBM 5150, and setting the jumpers to reflect this upgrade, my computer constantly posts with a 131 POST error, before continuing like nothing was afoot.
Has anyone had similar issues? I'll try and open the 5150 up tonight, and post specs on my 8087. Perhaps it's a too fast processor for my machine?
Please note, that no software test have been done on the 8087, except the "8087.exe"-utility from my IBM Pascal 2.0 disks. This utility detects the processor, and is seemingly able to dis- and re-enable it.
Any thoughts on this issue are most welcome!
Cheers,
Anders

Seems I must have inadvertently knocked one of the PSU cables loose, when installing the 8087... Once properly reseated, everything works like before...(!)
Well, apologies all around to those of you, who's spent time working on a solution to this man-made error of mine. One good thing came of it, though; I got to purchase new tools!
Cheers, and thanks again!
