Seeing Howard Nurse's name here awhile ago made me think about his first genealogy program (I think) that he came up with. It was the first program I ever bought and was back in about 1982, I believe, to run on my Heath H-89 that I had just built. There were 2 versions of the program, Roots/89 which ran on Heath's version of MSDOS for the H-89, and Roots/CPM which ran on CP/M for the H-89, Wish I still had them, just for sentimental reasons. But, then, that's the LAST thing I need now is something ELSE to have around "for sentimental reasons" only!
