The interresting thing is that this page states clearly: ".R ZKDJ?? SWR = 000000 NEW =" ..and other programms are behaving exactly like that, but not that ZKDJB2.BIC test I have: .R ZKDJB2.BIC ZKDJB2.BIC CZKDJ-B-0 KDJ11 CPU DIAGNOSTIC CZKDJB END PASS # 1 CZKDJB END PASS # 2 CZKDJB END PASS # 3 CZKDJB END PASS # 4 CZKDJB END PASS # 5 CZKDJB END PASS # 6 CZKDJB END PASS # 7 CZKDJB END PASS # 8 CZKDJB END PASS # 9 ... CZKDJ-B-0 ^ Huh? If the line clock is disabled I get the error like this: BOOTING UP XXDP-XM EXTENDED MONITOR XXDP-XM EXTENDED MONITOR - XXDP V2.5 REVISION: F0 BOOTED FROM DL3 124KW OF MEMORY NON-UNIBUS SYSTEM RESTART ADDRESS: 152000 TYPE "H" FOR HELP ! .R ZKDJB2.BIC ZKDJB2.BIC ERROR WHILE TESTING BOARD FUNCTIONS ERROR # =001166 ERROR PC =040662 043632 @ ..regardless how exactly it is disabled. Here I have done this trough switching the clock off with the DIP Switch on the front Panel PCB. Exactly the same occurs if I put the Jumper W9 on the pins and let the Switch in the On position. At the bottom of the description page: "New revision of DCJ11 (J11 CPU Chip) chip has a change to fix a problem found with ASH and ASHC instructions. The old diagnostics (REV B1) will fail with the new DCJ11 chip set installed. You need a patch." ....??$&/#%*/?? What is an old chip an what is a new one? There are several revisions of J11 Chips out there... So the question is: Was the writer of the test description drunk? All other tests I've tried (MMU, FP, Memory) are ok, regardless wich J11 I'm inserting and if the board is running with 15.2 or 18Mhz Clock. Regards, Holm -- Technik Service u.
