I did a small amount of work with ISIS, but after I had used CP/M. I
used an Intel PDS development system for the 8051 to debug some
firmware; I think it was for DEC's SCSI floppy controller.

The PDS was interesting in that it was a portable system about the size
of a Kaypro and had *two* 8085s. ISIS gave you an A> or B> prompt, but
it indicated to which processor you were speaking rather than which
drive was the default.
