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.

I've enjoyed learning about Plan9, how would you say they compare as systems?
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.
