Indeed. I use it with only one single gpib slave device attached. Also you may or may not have to fiddle with the parport settings. Either by writing to the superio registers, or by changing settings in the bios.

Take care that you need the correct line drivers. Before the 82357B,
the E5810A I used an Atmel AT89C55 to develop a GPIB-serial adapter
but only one GPIB device I was able to drive...
