I bought a VarIO from individual computers and it is a great product. It contains a fast serial and a fast parallele port plus it is zorro or clockport. I had mine first as clockport than plugged it in one slot of my zorro4 board.
Higher transfer rate when using a modem connected to the internet because of the FIFO cache and faster printing plus you can plug a parallele zip drive from the pc world.
What do you want more for 100 euros (AFAIR).
