The T414 was the first useful but affordable Transputer.
It was 32 bit but lacked the floating point hardware of the more expensive T8xx series. Later on there were even cheaper T4xx chips, which were relatively easy to get on a PC expansion card with slightly crippled tool chains for occam.
I still have a couple of T414 boards. I mostly run Helios on them: a parallel universe version of Plan9.
- bear8642 4y agoJust to check - by Helios you mean <https://en.wikipedia.org/wiki/HeliOS https://en.wikipedia.org/wiki/HeliOS>? I've not heard of it before. > a parallel universe version of Plan9 I've enjoyed learning about Plan9, how would you say they compare as systems?
- __d 4y agoYes, that Wikipedia link is the one I mean. It was sold independently but was also the native OS of the Atari Transputer Workstation. Like Plan9, Helios has servers that export a namespace into a common tree. The Helios server protocol is very similar to 9p. They appear to have evolved independently though. Plan9 allows each user to manage their own namespace by mounting stuff into it. In Helios, there’s a shared global tree that spans all the Transputers in the system. Both are Unix-like, although Helios probably tried harder to maintain a POSIX-like API.
