nerdling couple of questions:
Is that system walters old one he ran at hurstville?
Also with version you are running 98 is very stable to be honourst when I was running that version the system was bullet proof on 98 but when or if you go to 8.3 xp is the better operating system for it, because 8.3 was built in xp so if you don't run it in that operating system you get the problem that Tamworth had and what I had when I used it about two years ago.
