I haven't used one recently (duh) but IIRC the keyboard was similar to
those on LISP machines -- remember those? I think the industry prefers
special software tools on general-purpose machines, rather than having
a box for every tool.
I think moving to a Unix-based box was the right move for Rational.
Having a separate box required them to be a hardware and OS vendor,
in addition to an Ada tool vendor. And, any advances in Unix would
not be reflected in the R1000 -- they'd always be trailing the OS pack.
It also required you to buy (or rent, I suppose) a box in order to
try out their tools. They had to bring a box just to show you a demo.
As a customer, you'd have to get a really amazing advantage to
justify buying a bunch of new hardware, making your people learn
a new OS, and settting up support for the new hardware and OS.
The R1000 was a nice development environment, but it wasn't THAT
good. (I don't know how it COULD have been.)
Besides, their current tool, Apex, which runs under a normal OS,
gives many (non-embedded) projects the luxury of hosting their
development on an instance of the target machine. This can make
early testing a LOT faster and easier.
