I am still running several W/98 machines. The software may not be supported at microsoft but that just means they have finally fixed all the bugs

Software never goes bad, you just start getting hardware that won't run on it. (drivers) but before you give up, look at the manufacturer's site. There may be a driver for an older piece of hardware that still works. If you run old hardware, the old software is perfect for it.
New software is just a trap to make you buy new hardware.
Want to see a screaming fast machine? Run W/98 apps on a machine that was made to run XP. (any P4 with a gig or so of RAM).
Bill Gates seems to have dropped that deal about loading XP on another machine too. It used to be that you had to jump through hoops to move the registration from one machine to another. Now it just goes through when you do the register on install option. I haven't tried to run the same S/N on two at the same time tho. I bet it will gripe about the first one the next time you hook into microsoft.com and it runs the verify routine.
I know the last one you registered the software on works tho. (downloading media player or one of the other things that wants to run verify)
