Luckily the 'fried' part turned out to be a fusible link on the motherboard and was easily repaired. This was an old board, though, and I've certainly not had any problems with more recent boards. I'm not sure why fusible links were thought to be necessary. Possibly it was the early days of PS/2 and there was uncertainty about what people would be plugging in to those connectors. Wayne
