Looking for info on Controlware

I have a customer with a system that has an open controller in an Allenbradley SLC rack. It appears to be a computer that is sitting in the first 4 slots of a rack and has the p/N 1747OC-EDAAA In the first slot which I believe is the actual PCU and RAM unit.

Next to it are a VGA slot, a PMCIA slot and an IDE slot.

The thing programs in somethign called Controlware but I'm having difficulty finding anything about it online.

I found an AB press release from 1999 about it but not much else on if anyone took it over or if there is a migration path to newer technology.

Any insights appreciated.

Thanks,

It might pay to call AB tech support and talk to their SLC guys on something obsolete like this.

AB sold an "engine" that enabled programming the OC using IsaGraf. I can't recall whether that was called ControlWare.
There's a company in Montreal (forget the name) that took over IsaGraf and did some systems using the OC.
