It wouldn't suprise me if it got confused when you hooked a RM03 (real or emulated) to a system and tried to access it with the "DP:" driver, but that's "operator error". There are several DECUS-distributed RM03 device drivers for RT-11, and there were also a couple of commercial ones sold by third parties in the 1980's. The most likely DECUS driver is library entry 11-517, "System Device Handler For RM02, RM03, RP04, RP05, RP06 and RT-11 V4". -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
