They think they will make some money out of them?

We use several 1000 DSP's for front end conditioning of real time data signals.
Our data path basicaly consists of a big 100MHz FADC per channel followed by a
DSP per 16 channels followed by a Tputer network (100 off analysing 4096
channels). The DSP's are good for raw crunching of data, the transputers are
easier to program and also handle message passing better. It's an architechure
that works (well the simulations work anyhow) precisely because the DSP's and
transputers are complimentary.

If we did not need the Transputers for analysis we would still use them for ease
of downloading code.

It went rusty - important lesson *DO NOT* take your Meiko to sea with you.
Even a short dip in the bath with it is inadvisable.
