-
- As one of the people probably most qualified to talk about the Unison, I
- think I should say something. Sure they were slow. But they were the
- fastest machine that would run a pretty good Unix for their price. I think
- the only other Unix "micro" at the time would have been a Sun. Suns were
- not much faster and considerably more expensive.
-
- The Unison used an 8MHz 68000 with as little as 256k bytes of 2-3 wait
- state memory. The original IMI disk drives held 20 - 40 Mb, were heavy
- enough to give you a hernia carrying them, and were so fast that you
- could count the bits as they went past.
-
- Melb Uni did a (very simple) benchmark on various machines and the Unison
- was well down the list but not completely last. In one category (context
- switching), the Unison was the fastest machine by an order of magnitude!!
- Admittedly we cheated but it made the Unison proponents (I'm not sure that
- is the right word) laugh at the time.
-
- Email were definitely the wrong people to market the machine. It could have
- been a great success with the right management. But I'll bet it would never
- have made the sales predictions given to Email when they decided to but it.
-
- I belive that Bruce Paterson has answered the original question of whether
- there are any Unisons still alive. I have a few Unison brochures and PCBs
- that I kept as souvenirs (they also make good cheese boards!!), but I don't
- know of any other running machines.
