 if you get a parallel port one, you'll need a parallel port at 0x378,
 which means you either need a native port built onto your board or,
 like me, a PCI one and a Windows XP VM which pretends that port is at
 0x378.  
I did that--got a Superpro/L cheap and hooked it up to a HP thin
client (with real serial and parallel ports)  that I got for next to
nothing.  Install DOS with networking or Win9x and you've got a
complete package.
The Wayback machine shows that around 1998 or so, there was a Windows-
GUI programming software for the Superpro/L, but the file isn't
available.  Would anyone have a copy of it?
