95b and c support for usb isn't worth it's weight in salt, better go for 98 if you want usb. And like Fred said, PS2 should do as well to free up the comm ports. Hard to find a sun station under $10
Now as far as the windows proggy, not having seeing either, I would respectfully argue that the dos program may be as good and be more stable. Since W9x does not offer real multi-user/multi-tasking functionality, the only real improvement in the program itself may be graphical. True the G has been added to the UI, but to many, that's just overhead
The drawback is stability. As far as I know, in this case, the win version is 100X better and should be considered, so ignore my rambling
I have a 386 with ps2 sitting idle in the garage, with maxed out memory (16MB)
