Both ran cp/m... I'd forgotten about these older boxes. Yes, there are some parallel- port interface boxes around, which could hook a hard drive, CD-ROM, or other nifty device to a parallel port. In my recollections, though, drivers were always a problem - getting the driver loaded and having it stay resident often took some tinkering. <SNIP> >While we're on this subject, I have a couple of external cdrom drives here >that use the same style of connector.

If these are the external parallel port-connection CD-ROM drives, I don't think you'll be able to operate them chained together, anyway. There will likely be driver conflicts, as well as (likely) outright hardware conflicts. I think what you'll want to do is add another parallel port, instead - DOS supports two easily, three with some care and attention to interrupts. Anthony J.
