Well, this evening I fired up the PDP11/44 machine that I drug to VCF5 and back... it has moved into the house to live in what would have been the dining room, had I not made my office there. I thought of leaving it in the garage and just having the teminals in here, but it's getting regularly down into the teens and below at night, and Winter is hardly here yet... Anyway, after checking things out visually, I powered it on and the monitor immediately trapped to the console and halted. Ah. Schiess/Merde/Caca! Okay, no problem, something shook loose during all the moving and loading/unloading.. I powered down and re-seated the cards. Power back up, same thing. Starts to boot, traps to ODT, proc halts displaying the address it's stumbling over. I paused to give vent to language that is best represented by ASCII line noise. BUT: I have doc! I have Processor Manuals! I have the Technical Manual! And, using ODT, I found that the system was trying to boot the ESDI drives and failing. I'm so proud of myself - decoded the error codes, followed the registers to what was hurting... the Dilog 626 has died... tried to boot from the RL02 - that works fine. Got the other 626 from the other (dead) /44 chassis - now all is well. SO - I'm looking for another Unibus ESDI controller.... as well as all the other Junque. I'm supposed to have a SCSI card on the way - if it works it will have been a Good Deal. If it's trash - oh, well: keep looking. And there you have it. Cheers John
