Has anyone had experience dealing with Ironics? We have an Ironics Performer (ha!) 32 running SysV, and it just loooves to crash. It spits out trap 165's seemingly at random. Its MMU faults. The VME bus dies. All Ironics ever tells us is "well, if you updated your boards with this little thing-um-a-jig $900 hardware upgrade, that should fix the problem..." Did these people ever build a board right *the first time*? It seems like they are milking us for their own screwups. Argh.

It seems >like they are milking us for their own screwups. hey, motorola was late with the PMMU, and ironics (and many other companies) had to ship *something*. most other companies don't even offer a PMMU upgrade. curt mayer p.s.: get a third party c compiler. the stock unisoft c compiler is sheer garbage. i suggest gnu C. it's worth the money.
