The revival process of the 11/750 continues. The power supplies is working good and then I started testing the actual machine. But that was not a very smooth journey to success. I have in total at least three complete CPU board sets and just after quite a lot of board swapping it got running (I think).
I had error like: * Bright red error light * No response at all on the console * %C microverify error * %O microverify error * An hexdump prompt which non like above bot still not correct. * etc Finally I had the %% which meant that it passed microverify. Then I used the (second) RDM module (the first one had RAM error) to run the DPM and MIC test which passed. The I ran the "Hardcore VAX instruction test" / TU58#7 which also passed fine. BUT the Cache / TB diag, TU58#5, give me this: %% 00000000 16 >>>B %% @?ECKAL -- VAX 11/750 Cache/TB Diagnostic 00003488 06 >>> I am running a BE-S198Q-DE tape image. Anyone has a listing or description for the ECKAL diagnostic? Is there any know incompatibilities with certain revisions of boards? Or known bugs? The machine manage to boot the console tape so I get the BOOT58> prompt. But I am not sure if that indicate that it is indeed working or not. So, some help with the Cache/TB diagnostic would be very much appreciated. /Mattis
