NOTE: my problems are at the end of this message, got carried away to the extent someone might find this to have some useful info :^) I'm trying to run some tests on my /44 and have been having loads of fun with my lack of doc's on XXDP+. Note, for people in the same boat, I'd recommend Pete Turnbull's notes http://www.dunnington.u-net.com/public/XXDP.ps Though the best help I've found is having the doc's on the hardware I've tried to test. The /44 Tech Manual says to run 1-11 of the following tests in order (NOTE: I added the XXDP+ column). MAINDEC Operating Title XXDP+ 2.5 Diagnostic Sequence --------------- ------- ------------------------------- ----------- CKK FA <xy> 1 11/44 Diagnostic ROM* CKK AA <xy> 2 11/44 CPU/EIS KKAAB0.BIC CKK AB <xy> 3 11/44 Traps KKABD1.BIC CKK TA <xy> 4 11/44 Mem.

"C" indicates a PDP-11 diagnositic (not used on diagnostic disk pack or magnetic tape). <xy> = x = Revision Character (alpha) y = Patch Number (0-9) My single biggest problem seems to be stopping a diagnostic once I've started it. So far I've been resorting to stopping the CPU and rebooting, but one would think that there must be a better way, and that I've missed it. My second problem is the first test, I can't find a KKFA*.* test. Is there another test I can run on the diagnostic ROM? #3 is #3, but I think this is proper behavior CKKABD0 11/44 TRAPS NO FLOATING POINT OPTION PRESENT NO CIS OPTION PRESENT CONSOLE 17777707 023252 Problem #4 isn't that big a deal, the "M9312/11/44 UBI Boot" diagnostic complains that the DD and DL ROMS are in as DL and DD, while it wants DD and DL. #5 may or may not be a problem with the cache (real problem is my not knowing how to interpret it). CKKKAC0 11-44 KK11B CACHE RMI REGISTER (G5179) NOT USED-SKIP HI ORDER BIT ADDRESS TEST UNIBUS EXERCISER NOT USED-DMA TESTS NOT PERFORMED END OF PASS # 1 END OF PASS # 2 END OF PASS # 3 <etc,etc,etc> I solved #6 by finding and substituting the ZMSPC0 memory test for ZMSDD0. Opps, guess I didn't try step 11, and 12-14 can't be done at the moment as the FP11 isn't installed, and I don't have a CIS for #15, 16&17 both complained. Zane | Zane H.
