Tried my M7838 EIS this morning. It is bad or there is a config/jumper issue to investigate. With the EIS installed I cannot boot RT-11 5.3 nor UNIX 6.
The good news is that when I attempt to boot UNIX 6 I get a different error than before. Now, when I run rlunix at the ! prompt, the system responds with all data lights and address light 1 ON. The system still freezes, but it's less "dead" than before, seems like it gets farther along indicating the bootstrap at least starts before the EIS board fails somehow. Now I have XXDP+ on a disk pack and I can run diagnostics on the EIS board, if the system allows me to boot XXDP, see what happens. Bill
