Oh my that is amazing. I have not seen one of those since the early '90s. I worked on the hardware side of a project written in Ada developed on one of those boxes. The FACIT terminals are nice, I ended up with one for many years after the Ada box was switched off. > It just occurred to me that RTEMS might have been a target for > cross-compilation > from the Rational R1000-400 back in the '80-90s. I remember Rational provided their own run-time. The target hardware we had was a DY4 68020 processor with hardware floating point. > The R1000-400 is a machine intended for team development and maintenance of > large Ada systems: > https://en.wikipedia.org/wiki/Rational_R1000 > https://datamuseum.dk/wiki/Rational/R1000s400 > > A log of our efforts to get it running, with some picture can be found here: > https://datamuseum.dk/wiki/Rational/R1000s400/Logbook > > If there is anyone here that may have some history, stories or knowledge > related > to the R1000-400, we would be very interested to hear about it.

The run-time parts I saw had a tick and basic tasking and I think an interrupt pragma but I seem to remember the software had a lot of sleeps and polls. All best with project.
