For a time, in the late 70s, I used a Lanier word processor based on an 8080 chip. The whole shebang cost about 25 grand.
25 Grand. I think that was the downfall of the single vendor suppliers. They had customers over a barrel. I remember my billable rate for hardware repairs at the time was $300 per Hr. with a 2 hour minimum plus travel time charges. They would also rip off customers for telephone support, supplies, etc. That may have been the impetus for the move toward PC clones.
