Yes I have done a lot of multithreaded code, working on a VAX, Starting on a transputer and then collapsing the nice clean parallel code to multithreaded mush is probably the easiest route to multithreaded.... But do you REALY want multithreaded, CSP is much easier to use. Do you have to use a 386 ? after all a TRAM card with a megabyte of RAM costs around $500, with an onboard FPU. I can't imagine a 386 system being any cheaper.. > The other thing is that I will be doing some image processing. This > implies that floating point work needs to be done.

The Intel chip is basicaly a bodge designed to allow people to make fast IBM pc's which will run a choice of three crummy operating systems equally badly. If you want to play around with parallelism, a T800 network is probably the best option. If you need serious computing power then take a look at the i860, with some communications chip (a Tputer even!). Unless you have a *REALY* huge problem I can't see building your own hardware as a soultion. Even if you get the labour free, by the time you are finished you will almost certainly be able to buy the stuff off the shelf cheaper. Phillip M Hallam-Baker
