I tried it and at first it seemd to work fine. After a while however the keyboard got an hickup and switched to CAPS, or NUM-LOCK or SCROLL LOCK or thinks ALT is depressed or RIGTH-SHIFT or CONTROL or... If one of those toggle keys was stuck than I could read the bios-flags and see that the flag for the offending key was set. After resetting the flag the keybloard was normal again, for the time beiing that is. I put back my 8088 and the problem was gone. Note that the problem is of sporadic nature, sometimes it was ok the whole day, sometimes it was wrong over and over again. Which key seemd to be depressed was random although the alt-key and numlock-key seem to be favorit. If the numlock was stuck than the indication light stayed off and the function of the numlock seemed to be reversed (on=off and off=on). I think it's an interfacing problem between my PC and my keyboard, and I want to solve it because i like to use the V20. I don't think its a design fault because with the original 8088 it works flawlesly (sp?). My keybloard is an XT type with the function-keys on the lefthand-side. I have the following questions: - Did someone have an simular problem and found a solution. - How does the PC talk to my keyboard (hardware-wise). - Could it have someting to do with the increased CPU-speed. - Would an AT-type keyboard solve my problem - Any other suggestions?
