PC servicing card

Using a PC is one thing, getting it going again after a serious hardware malfunction quite another. The servicing card presented here, a design by ELV, is aimed at two groups of PC-XT/AT users: first, those bold enough to declare war on defective add-on boards, and second, those engaged in developing application-specific hardware. One remarkable feature of the servicing card is that lt allows the card under test to be removed and inserted without the need of switching the computer on and off.
