Hi Managers,
Thank you very much for your replies and pardon for this later
summary.
My original question was:
> We have some Digital Unix machines running DU 3.2C, some PC's
> connected by Pathworks and some Mac.
>
> We are thinking about intalling a CD-ROM tower and a CD-ROM recorder
> to create CD-ROM masters.
>
> Our Digital representative salesman has told us:
>
> 1. There isn't a DU 3.2C client to access the CD-ROM tower attached
> directly to a network, so we have to attach it to a Unix machine.
>
> 2. The CD recorder can't be attached to a Unix machine, so we have to
> connect it to a PC.

> Are there any other configuration possibilities? Do the DU4.0 solve
> these setbacks?
