I've been fooling around with Microsoft's Virtual PC lately because at home I've one program I use that doesn't run well under XP and not at all under Vista.
So I installed Virtual PC and have a nice Win98 system available on my Vista PC.
It works so well that at work I installed it on our lab PC to run some old programs that work ok under XP, but not super-great. Some won't even install on XP.
So now I can use SolaCalc on our lab computer again, though I prefer the uncluttered GUI of the earlier version.
Since it was a free program, I was wondering if anyone had a copy of SolaCalc Plus V 2.05 since it appears my floppy from Sola is unreadable now by any machine.

Virtual PC is pretty nice, but still a bit limited, since there's no USB support for transferring data via flashdrive, but you can work around that by sharing a folder that you move stuff to from your USB drive on the host OS, the accessing the folder via Virtual PC.
