So I had a fellow list member show up and trade me an AUI cable for reading some of his old RX01/02 disks to see if there was anything on them. Not a big deal, TALOS (my 11/83) has pretty much everything: 11/83 CPU board with FPJ11 MSV11-QD card with 4mb memory (lots o' disk cache) RXV21 plus RX02 drive RLV12 plus two RL02 drives (and an RL01 in a pinch) TQK70 and TK70 tape drive DELQA Ethernet DZQ11 4 port serial board And the MTI ESDI disk controller with a 330mb half height ESDI disk Overall it's a pretty fast and solid system. I have RT11 on DU4:, RSXM+ on DU0:, and plenty of power to do anything. However when we fired it up we got nothing on the terminal. Great. So I went to TITAN, which is another BA23 equipped 11/73 with: 11/73-B board wo FPJ11 2mb memory (Datamation) TQK70+TK50 (my other TK70 doesn't write properly for some God unknown reason) DEQNA Ethernet (it works) DHV11 8 port serial board That odd little 3016 real time clock board I never seem to get around to loading drivers for RQDX3 jumpered for RD54 running RSX11M+ (not bad with cache) 20mb HH drive with XXDP+ utils 40mb HH drive with RT11 5.4 all drivers (last version that supports the TU58) That worked, we were able to move over the RXV21 and read the disks, but I was wondering what was wrong with my main system. So after he left I pulled it apart. Problem seems to be the MTI card was not booting up properly, and since it holds the Q bus in a frozen state until the disk spins to ready it was blocking the system. Pulled it, cleaned the pins with 1500 grit sandpaper, put it back in, it now works. Great. So every once in awhile I guess I have to check the pins on these old 11's. They run well and are starting to be used more, but they still have weird problems from time to time. CZ
