I have used skype v 1.0.0.106 in 98SE since its introduction. It
works well for skype<->skype calls and for outgoing prepaid L/D calls
but it does not support incoming calls, voice mail, or the newer
features such as plugins, etc. Dunno, but you may find it here:

I attempted unsuccessfully to upgrade to the next version after
1.0... but, although it worked, it left video artifacts on the screen.
That phenomenon may have been local but I have no interest in sorting it
out and have tried no later versions of Skype.
