If my own memory serves me correctly, IBM PC's don't actually use the parity bit, it's just there. Seems I remember some people simply leaving the chips out, or moving their flaky/bad chips to the parity bit socket because it didn't matter at all. Did any of the software use the 'extra' bit? I may be mistaken, it's been quite a while since I touched a PC, and I was more into learning about VAXen and UNIX at the time... ----- Leo E.
