> From: Paul Anderson > OK, I have 10+ of the M3106 and M3107 boards The M3106 is the DZQ11; the M3107 is the DHQ11, a completely different beast (a sister to the DHV11, the quad version of the DHQ11, the dual version). We already have complete documents online for the DHQ11 (UG, TM and FMPS), so no great need for them. Just to recap, what is missing online from the complete set of 4 (DZV11, DZQ11, DHZ11, and DHQ11) is: - DZV11 Tech Man (EK-DZV11-TM) - you have this - DZQ11 FMPS (MP-01795) - still missing, and the thing I'm looking for - A DHV11 User Guide, _if such a thing exists_ (I have no definite proof that it does) > if the print sets are filed under M3106 and M3107 instead of the option > name they might take while to get to. > ... > I'm slowly getting everything, prints, manuals,boards,etc. in order but > it will take time. Understood. Don't push your recovery! :-) > Noel, you are more than welcome to use any documentation. Talk to Al > figure out who needs it first then ship it to the other and back to me. For the DZV11 Tech Manual, that might be best going to Al? I don't have a page-feed scanner, just the manual one (albeit it is large format, and can swallow prints at a gulp), and since TM's are usually lengthy, probably best if someone with a page-feed scanner tackles that one. (I assume Al has access to a page-feed scanner.. :-) Noel

PDP-8/e Panel Differences

by rodsmallwood52＠btinternet.com

Hi Guy's The current debate has produced a growing list of differences between the front panels of just one model viz and towit the PDP-8/e Here's my list so far 1. Angle of selector switch positions 1 and 6 can change (change of switch detent angle) 2. The line around the switch position area can be present or missing 3. The lines splitting the lamps into groups of three may or may not be present. 4. Diffences in colour from machine to machine (not verified yet) These could be related to 1. Date of manufacture 2. Place of manufacture 3. Serial No 4. Option fitted ie programmers console change of switch type It would be nice to be able to correlate the one list with the other Suggestions plese gentlemen The current shipping panel has the line around the switch area and the lines in switch positions 1 and 6 are vertical Regards Rod

SVR4 tape "mount xx"?

by cclist＠sydex.com

I'm fooling with some AT&T tapes for System V, Rel. 4.0 and I see, along with the various "proprietary" and "copyright" stuff on the tape (paper) label and the description of the contents, the notation "mount xx"; e.g. "mount D5" or "mount E2". Exactly what does this mean? --Chuck

Need DZQ11 (M3106) Print Set

by jnc＠mercury.lcs.mit.edu

> From: Paul Anderson > DZV11 FIELD MAINT PRINT SET MP00462 > USERS GUIDE DZV11-UG-002 > TECH MANUAL DZV11-TM-001 Err, sorry to be the bearer of bad news, but it's a _DZQ11_ FMPS I needed (MP01795), not a _DZV11_ - the two are programming and interface identical, but other than that, totally different boards (the DZV11 is a quad, the DZQ11 is a dual). Sorry! However, the DZV11 TM is not yet available online, so it's definitely a Big Win, finding that; so your effort was not in vain! Noel

9T TU80-family in Wichita, Ks

by microfilm＠microfilm.kscoxmail.com

I've done some more research on the LMSI tape drive I have here, and it appears to be a TU80 family drive. It has touch pad controls, 2-digit LED display, vertical mount, pertec interface (I don't know if it's buffered or not), runs well and passes diagnostics. Layout and diagnostic controls match up to information from the TU80 manual on bitsavers. The drive has a dual-voltage power supply, presently set up for 110V operation, and is mounted in a cage which could be easily bolted to a pallet for shipping. I can throw in an ISA interface card, though I don't know what brand/models I have on hand, or whether I have software and drivers for them. If anyone is interested, photos are here: http://microfilmks.com/LMSI/ and I can get an operational video if necessary. It's available now, in Wichita, Ks. Asking $150, but I'm flexible. You pay freight. --Shaun Halstead Microfilm Services, Inc. Wichita, Ks 316.269.2203

Need DZQ11 (M3106) Print Set

by jnc＠mercury.lcs.mit.edu

So I'm working with a group of 'busted' DZQ11's (the symptom is that Master Clear - 020 - bit in the CSR stays set, even if I write a 0 to the CSR), and so I need access to a set of prints for this card; they are MP-01795. They don't seem to be online anywhere, though. (They may not be fixable, because a lot of the circuitry is in a large custom chip, which is of course now unobtainium, but I'm hoping it's something simple.) This is a relatively recent card, so I'm hoping someone out there has a set. If not, I can probably dope out how it works from the Maintainence Manual (which _is_ available), but it would be _much_ easier if I have some prints to look at too... I would gladly scan them in for general distribution/use, if someone has a set they can loan me. I do have an A3 professional level scanner on a SCSI, so it's a snap for me to scan prints. (Or if someone wants to scan them themselves, that's of course fine too!) Thanks in advance, and I'm crossing my fingers! :-) Noel

Michael - Many thanks for the great start! Lyle ok added yours.. neat you have it working! what is the status of his other unit that was sold? ok here starts the registry ! Have started on for classic 8 and one for 8S It would be good to have some assistance in figuring out want fields we want for data. Do we want the list to be ordered by S/N or owner? ( I vote for S/N) Of course if we also have things an excel work sheet we can sort in any way we wish. http://www.smecc.org/pdp-8.htm is page of what we have so far.

Looking for docs / schematics for MITS 88-HDSK and its associated Pertec drive

by derschjo＠gmail.com

Hey all -- I'm assisting in the restoration of an Altair 8800 system which includes the MITS 88-HDSK ("Altair Hard Drive Controller") and Pertec D-3422 removable pack/fixed platter drive and after cleaning everything up, rebuilding supplies, etc, the drive spins up and goes Ready but all attempts to boot end in "LOAD ERROR: 1" which I have been told indicates that the Altair doesn't think the drive is ready. I can't find any substantial documentation on the controller (the D-3400 series is covered on bitsavers); I've checked with the Altair Computer Club and they don't have any docs posted (and the one guy who might have a copy of the docs is on vacation until the 12th, which wouldn't normally be a big deal but we're trying (perhaps in vain) to get this thing ready for an event on Saturday...). Anyone have any docs or any other information for the 88-HDISK controller? Thanks! Josh
