Hello, Thankyou to those who responded to my query about the PS/2 Keyboard and mouse. I have found a motherboard which fits the case and has all the right bits working. Another I/O problem. If the bios reports the comm port addresses, does that mean that it has detected them and the ports are active? I am having more trouble with mice, trying to attach a serial mouse to a motherboard, via the comm port adapter. I have never experienced a ribbon failure before but wonder if this is the case. Cheers Nicki (who has been fiddling with computers for years and all of a sudden can't get things sorted!!)
