KE11-E M7238 EIS Diagnostics |

 industrial/11 with frozen front panel after attempting to load UNIX without a working EIS controller card. The KE11-E Extended Instruction Set (EIS) is required for UNIX 6.
Up to this point I had not messed with using the optional EIS card, M7238, KE11-E in my 11/40 system testing. UNIX 6 requires this card, so I am going to test the card. Not sure if it works. Here is the basic info for the controller: KE11-E M7238 Extended Instruction Set EK-KE11E-OP-001 EK-KE11 E-OP KE11-E/F USER MANUAL EK-KE11E-TM KE11-E/F TECHNICAL MANUAL MP-KE11-B KE11-E MAINTENANCE PRINTS The manual says to cut the W1 jumper on the M7233 Decode card, which I did, as part of installation, plus attach the three ribbon cables between the M7238 and M7232. When I run the system with the EIS card installed and the related jumpers, the system goes DC LO AC LO and I cannot do anything. I may not be able to boot into XXDP+ to diagnose the problem. But I can try again. I could not find any XXDP tests, so I put out a request on CCTECH and I was tipped to this page by Chuck Dickman: http://www.chdickman.com...tes/my_diagnostics.html In particular: KE11-E (EIS) Option Tests PDP-11/40 Basic CP Test ASH CKBI PDP-11/40 Basic CP Test ASHC CKBJ PDP-11/40 Basic CP Test MUL CKBK PDP-11/40 Basic CP Test DIV CKBL MUL-DIV Random Exerciser CQKA NEXT: Put the card on a riser and test the components electrically (caps, etc).
