Re: recent discussions Found this in section 14.38 of the VMS FAQ: http://h71000.www7.hp.com/wizard/faq/vmsfaq_016.html The protocol definition for the old DIGITAL keyboard and mouse interfaces is buried at the back of the QDSS section in the old VAXstation II manual, specifically, in the back of the VCB02 Video Subsystem Technical Manual (EK-104AA-TM). The keyboard wiring and protocol is in appendix B, and occupies circa 44 pages. The mouse is in appendix C, circa 12 pages. ... in case anyone wants to tackle a protocol converter.
