Heathkit H-89

Finally in 1980 my father was awarded a generous bonus for his role in the creation of special radio equipment for use on aircraft carriers. He used this bonus to buy an H-89 kit for Heathkit. http://www.old-computers.com/museum/computer.asp?c=135

We finally had a real computer in the house! It ran CP/M and H-DOS (we use mostly this OS) and we had a couple of different versions of BASIC for it. We had something called Benton Harbor BASIC. The computer had no graphics modes, but it had graphics characters and I remember my brother Ernie was working on a version of Galaxians for it. We wrote a bunch of games. I remember my father also did some assembly language programming for it (or perhaps he just typed in straight machine code).

One thing I remember about the machine was that it used hard sector diskettes, and the floppy drive was loud. It would make clunking sounds. Ka-chunk, ka-chunk!
