It would be called something like an imp11. Also, >are there any Unix drivers written for it? Be aware that DEC CSS made two different IMP interfaces. The first, the IMP11-A, was based on a pair of DR11-B interfaces. The second, the IMP11-B, was based on the KMC-11 microprocessor. The css driver in BSD 4.2 was for the IMP11-A and I doubt it will talk to an IMP11-B given the difference in base hardware. "Art Berggreen" ------
