- Another point is that C= never saw a viable market for transputer
- products. They built a working prototype, but as one of the C= engineers
- pointed out last week, it was dropped because C= didn't see much of a
- market for transputers (transputers aren't cheap). Atari developed a
- machine called the ABAQ which was basically an ST providing the user
- interface and front end, and an array of transputers as the heavy iron
- hanging off the ST. It wasn't a big success.
-
- I have one of the CSA Transputer Education Kits at home and I for
- one would *love* to be able to add a transputer card to an Amiga. As it
- is, the closest option is to by an A2000, 3000 or 4000 and a bridgeboard,
- then plug the transputer card into the PC bus and drive it from the
- bridgeboard (not quite the same thing as being directly on the Zorro
- bus). Perhaps we aught to ask CSA to make an Amiga version, they make
- other Amiga stuff (such as accelerator cards). The first thing I'd do
- with it is port Rayshade. 8-)
