God I'm tired of "vBulletin's Expired Tokens". Lost another post just now because of it. The advice to hit the "Back" button to recover your post doesn't work, and there is no indication it auto-saved. I'll try to reconstruct...
On ODT:
I still wonder if there was a missing card in J4B, and what it might have been.
The idea of re-seating socketed parts on the Disk Controller board is risky, but if you have the confidence to try, it may help. Could we put that idea in abeyance until we get a little further along?
My non-DEC documentation is limited to only a few vendors. Unfortunately, none of yours are on my list.
We can stumble along on this road without documentation and probably get somewhere, but it's going to take a little time. Correct documentation will be the best way to speed things along. I suggest we continue trying to find some. A good start would be the memory board, with the Disk Control being a good second.
- Glen - I apologize to you. I didn't mean to be contradictory, only to indicate my feelings that DEC documentation may not apply to this backplane. I now see we are in agreement.
- On the Drive cables - Again I agree, I don't see them. This is why I asked about the board from J2B, which I'm guessing is an RQDXE like board, possibly to break out cables for drives. All this is supposition on my part till we see pics.
- BOOT - yes, I'm going to assume there's a courtesy boot ROM in the set somewhere. You seemed more familiar with this vendor [SMS] than I, and I thought you might have more specific knowledge on this.
- SEgamer - yes, thank you - that is the CPU. I'll research it. I see it has the MMU installed.
On ODT:
- Please perform a little experiment for me: Get the system to the ODT prompt ["@"] and enter "0/" then <LF> [which is CTL-J on a PC keyboard in Hyperterm]. Post the entire sequence here.
- When you did that test on address 17773000 and 17772150, was the QUAD board installed in SLOT 0 at the time?
