The above mentioned solution seems promising (i.e. inexpensive) and I would like, if possible, a more detailed description of the process of piggybacking(?) the drams. Since I am no expert (but learning :-) on this sort of thing, perhaps one kind soul could mail me either a reference or "walk-through" instructions on the installation of the drams. thanks mark enriquez acs60222@zach.UUCP
