So I doubt the brochure would answer any of the remaining questions; we'd probably need the Engineering Drawings for that. But there's so little on the DM11, it might be interesting to see the brochure. The big issue with the TM is that it has the same erroneous diagram for i) the boards in the DM11-A, and ii) their locations in the backplane, as the one in DEC-11-HDMBA-A-D, "DM11-BB modem control option manual", on pg. 1-5. The diagram there lists: M7245 Transmitter E M7244 Transmitter D M7245 Receiver M7242 Control C M7241 Control B M7240 Control A So two 'M7245's, with different functions listed! And no M7243... The DEC "Spare Module Handbook" shows: M7243 "DM11 transmitter D" M7244 "DM11 transmitter E" M7245 "DM11 receiver" so the M7245 probably _is_ the receiver; but this list shows that the 'transmitter E' card is the M7244, not the M7243 (as would be if the top line from the module diagram had a typo '5' for '3'. Hence my observation that it would probably take takethe ED tostraighten thins out. But as I said recently, no real need; the thing is a total canine, and I doubt very much that there are any left in the world. Noel

I mean, there are no DM11-AA documents of any kind online, so it would be interesting to get some (there are still a few un-answered questions); but there's a good DM11 entry in "pdp11 peripherals and interfacing handbook", 1972 edition, that enabled me to produce a decent entry: https://gunkies.org/wiki/DM11_asynchronous_serial_line_interface which is probably more than good enough - the interface is actually a dog, I doubt any still exist. Noel Yeah, I figured that out later. ;) BTW, I have only the sales brochure for the DM11, near as I can tell. 114X-00871-1715/J .

> From: Al Kossow > Date: Mon Aug 9 14:05:07 CDT 2021 Wow! That was _amazing_ speed, to get that uploaded so quickly (even if you had already scanned it in), considering I only posted my request at 14:32 EDT! Thank you very, very much: that allowed me to complete the DQ11 page on the CHWiki: https://gunkies.org/wiki/DQ11_NPR_Synchronous_Line_Interface The MM was unclear on many points (including the backplanes; the MM says, in 2.3.1.2, "double-system unit", making it sound like the option version uses a 9-slot backplane, but it's actually two 4-slot units). You aren't by any chance sitting any DM11-AA manuals, are you? :-) (The weirdest interface I've ever seen; the shift registers are kept in main memory, resulting in many DMA cycles _per character_.)

Re: DQ11 prints needed
ROTFL - especially given the earlier case, and since Noel knows about you folks quite well.. Typically I search the "mirror" on my drive first (which I update about once/year), then if I come up empty, search the bitsavers site. BTW I hope to scan the Xenix manuals tomorrow. If not, it will have to be next week. JRJ On 8/9/2021 2:05 PM, Al Kossow via cctalk wrote: On 8/9/21 11:32 AM, Noel Chiappa via cctalk wrote: Anyone have a set of DQ11 prints?
