that CP/M could have possibly been our main stream OS.. How could so ma < great ideas get lost in the big shuffle..? Yes I ahve a lot of the 8bit stuff like DRGRAPH. < I know everyone has been talking about GUI's, and according to this arti < Digital Research did alot of work in this area. And real product for both 8 and 16 bit systems. < Also Digital Research back in 1989 released a very good DOS called DRDOS < used this for awhile back in 1990 and was very impressed with its featur < then MS came out with a clone of it called MSDOS ver 6.0.. I still own < several original copies of DRDOS in unopened packages.. What you missed is MPM-86 and CCPM that DRI did before DRDOS! Btoh of wich were a significant advancement over DOS. Allison
