DEC ADV11-D Analog to Digital converter with DMA

by mark＠matlockfamily.com

Paul, Jerry, Thanks for the suggestion to take a look at DataTranslation! Looking in the bitsavers folder for DataTranslation, I found a 239 page July 1986 Data Translation manual for the DT3362 series of A/Ds. There are 23 sub-models of that board but the DT3362-16SE/8DI specifications matches the ADV11-D (A1008). The best part is that chapter 8 of this manual has 5 programming examples, two of which use the DMA capability.With a bit of research (and some luck) I think this will give me the info I need. Thanks again, Mark Date: Sat, 17 Oct 2020 02:06:25 -0500 From: Paul Anderson <useddec at gmail.com> I think they were made by Data Translation.

Toaster Flyer - proprietary drives?

by jules.richardson99＠gmail.com

I've been talking to the guy in NYC who has the storage portion of what appears to have been part of a Toaster Flyer setup (I forget who, but someone on the list forwarded details a few months ago) - two 5.25" full-height SCSI drives, a 3.5" SCSI drive, passive ISA backplane, and some form of TBC card (made by DPS). I'm not sure who made the 3.5" drive, but the two FH ones appear to be 9GB Seagate Elites (I'm assuming they were the two video stores, and the 3.5" was for audio). The big question is whether in a Flyer environment the drives run custom microcode or will have been LLFed to something other than a "standard" 512 byte block size - I believe that the Flyer was really pushing the boundaries of what was possible when it was current, and the majority of drives on the market just didn't have the necessary throughput (I see a "Newtek approved" sticker on one of the Seagates). I know that the storage was considered "proprietary", but I don't know if that just means that the filesystem was Flyer-specific (i.e. not AFFS), or if there was more to it than that. cheers Jules

S-100 stuff, electronic stuff, model railroad stuff, books and magazines!

by mechanic_2＠charter.net

Hello all. I have 22 S-100 boards for sale. There are two backplanes. One is a 9 slot bare board and the other is a 19 slot fully populated board. Both boards have active termination. There are 8080, Z80, FDC, HDC, Serial, 68030, a Display board, a Front Panel board. There are also 3 Mean Well power supplies supplying the +9VDC and the +_16VDC. There are also voltmeters and amp meters . I want $500 plus shipping for all of it. I can provide a full inventory and pictures for anyone who is truly interested. I probably have cancer and if I do I am dying. I want all of this to go to a good home and not to the landfill. If anyone is interested I have some test equipment, electronic components, and model railroad equipment Please only serious inquires for I tire very easily. GOD Bless and Thanks, rich!

Configuring an MS11-L for an 11/24

by cz＠alembic.crystel.com

So I'm working on this old MS11-L board I have had sitting around forever. M7891 DK. Goal is to use it in my 11/24 with KT24 MMU. I've switched the jumpers so it will run on a +12 supply instead of a +15, and so it will run in an extended Unibus slot as opposed to a normal unibus. However I'm stumped regarding the +5v and +5 BBU supply lines. The problem is the manual says to set the jumper that is above C12 (bottom of board, two capacitors next to each other, pretty easy to spot) so that W3 is in and W7 is out if you just have +5v. On this board, W3 is out, W7 is in, but there are two other jumpers right above them (nothing is labelled on the board). So.... Is it the bottom jumper that is +5 or the bottom and the one above that need to be moved? This might be why this board never worked right, if the memory refresh is expecting power on the BBU line and I don't have that then it's not going to work very much :-) But which jumper is the right one to use? Thanks! Chris

Identifying a Mystery ISA Card

by w9gb＠icloud.com

Sean - You might get lucky, IF Jameco still has documentation & software for the board. I would guess circa 1982-1985 (after IBM XT introduction with 256 kB standard). ? Japan in 1970s and Taiwan in 1980s ... had major production issues with PCB fabrication and assembly (required higher QC in source materials). ?After-sale? (under warranty) Component-level service bench techs ? were frequently heard ?swearing? at the incompetence across the Pacific. ? Thru-hole ?vias? for double-sided boards frequently failed. Solder alloy and Flux formulations (Asia didn?t want to buy Weller or Ersin/Multicore) were especially troublesome. In many instances, the old solder has to be removed (difficult de-soldering due to impurities in Asian solder). These problems continued through 1980s, until the ?bad shops? closed or changed their production operations. ? Using a Quality 63/37 or 60/40 ?RA? solder (like Kester ?44?), resolves most issue, other than copper solder trace failures. greg === From: Sean Ellis <seanellis9 at gmail.com> To: Chuck Guzis <cclist at sydex.com>, "ClassicCMP? <cctalk at classiccmp.org> Subject: Re: Identifying a Mystery ISA Card Well, thanks for all the help guys - Finally narrowed it down to a JE1078 on Stason: https://stason.org/TULARC/pc/io-cards/I-L/JAMECO-ELECTRONIC-COMPONENTS-Mult… I can believe this thing was made in Taiwan - I had to repair probably 1/4 of all the joints on the card because they all had gone dry or had holes in the joints. Have you ever seen solder bubble like boiling water? That's how bad the original solder on this card was. It also absolutely stank the whole way through...

DEC ADV11-D Analog to Digital converter with DMA

by mark＠matlockfamily.com

I recently acquired an ADV11-D Qbus A/D board and having been working on a RSX11M+ driver for it. It is similar enough to the ADV11-C that the driver I wrote for the -C works ok, but the -D is DMA capable. It seems to have two extra CSR registers in addition to the CSR, and read buffer. Does anyone have documentation for this board? It is mentioned in the Oct. 88 Microsystems Option Guide and both RSX and VMS supported it. It was also mentioned in the Dec 92 Real Time Products Technical manual. It has a 40 pin IDC connector that appears to have some amount of differences from the ADV11-C and no where have I seen any info on the DMA capability. Does anyone have a ADV11-D user manual or XXDP source code for testing it? Thanks, Mark

Identifying a Mystery ISA Card

by w9gb＠icloud.com

Sean, Fred, and Glen ? Sorry, late to this ISA card thread. I worked in Tech Support for an Apple/IBM/HP/Novell retail computer dealer, during summers in early 1980s, when in Graduate school. So I saw the ?wide selection? of add-in cards for IBM PC/XT and compatibles. == This is a ?Taiwanese generic 6-Pak? Add-In (8-bit ISA) expansion card. RAM 384 kB; Serial port, Parallel port, Game port, AND Real Time Clock ! Glen is CORRECT, the National Semiconductor MM58167 is the RTC IC. Texas Instruments bought out National in 2011, data-sheet still available. The ?solder-in? B1 battery has been cutout (open space below/left of MM58167). Replacement battery (likely ~ 3 to 3.6 Volt) can be acquired from Digi-Key. Take measurements and closeup photo of ?B1? Area, to CONFIRM Model and Size. ? My Quick Guess ?

Firing up the pdt11

by cz＠alembic.crystel.com

I'm back to working on the PDT11/150 again, the bottom floppy is weird: It doesn't read rx01 disks, period. Top one is fine. So I tried swapping all of the connectors on the control board so the top one was PD1: and the bottom was PD0: Sure enough the top drive works fine as PD1: and bottom is still dead so it's a drive issue. Pull the drive, put in a spare, button it up, and sure enough it still doesn't work. Any ideas? Also I recall my MiniMinc/150 (which is in parts in my shed) had EIS and FIS, but this one only reports FIS. Did DEC make pdp11/03 expansion chips that only had FIS? C

PDP 8/L & 8/I G228 warning

by djg＠pdp8online.com

Noticed in another thread an 8L is upcoming on the persons restoration list. Making separate post so more visible. The G228's have a 20 uF 50V electrolytic capacitor on them. I have had two short. When they short its a race between the trace on the board burning up or the backplane 30 AWG wirewrap wire burning up. One was on an 8/I I was restoring where the backplane wire providing the power burnt up at power on. Wasn't shorted before power on. The other was I saw one G228 had a burnt track while I was washing the cards in an 8/L. I had not applied power at that point so that was old damage. Usage history is unknown. As a minimum I would recommend applying current limited 30V to the capacitor on each card out of the machine before initial power on. Low enough limit may allow the capacitor to reform without shorting. The same part # capacitor is still available for protective replacement. The capacitors don't read shorted before power is applied. Unknown if they will short if the machine is powered on periodically. I've head lots of reports of all the failures in 8/L's. I replaced the one G228 and some bulbs but otherwise the machine was fine. It did need a lot of cleaning and I did do my normal power supply reform and checkout.

AOL CD and other old PC software...

by wh.sudbrink＠verizon.net

Like most of us, as a result of COVID, I've been mostly stuck at home. Consequently, I've been going through and organizing a lot of boxes of old stuff that just accumulated and I did not consider to be part of my vintage computing collection. However, I have noticed (and chuckled over) the fact that others are collecting computers and software that I "just used". Anyway, I'm finding stuff that I think others may appreciate more than I and I'm wondering about its value. First, I have what I believe is a pretty early AOL CD and I understand that it may be collectable. It includes the original silver, blue and red cardboard sleeve that reads (in part): America Online CD-ROM! IT'S NEW! IT'S FREE! Now with World Wide Web Browser! Any thoughts on this would be appreciated. Most of what I find with Google seems to be related to a boom about five years ago. I have also found boxes full of other software, along with their original packaging. Original DOOM, original Lemmings, Wing Commander, Wing Commander II, Falcon, several old Microsoft Flight Sims, etc., etc. Thanks, Bill Sudbrink -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Ok, with the PDT and the RX02's out of the way I'm running down to the wire on fixing stuff before I tackle the 8/L's. Next up is the 11/24, this is one of the 5.25 inch rack mounts with a CPU, KT24, and no memory. First question: Will ODT respond at all with no memory on the Unibus? Second question: Can a 128kw memory board from an 11/34 work in an 11/24? Or do I need one of the 11/44 boards to make it go?

Identifying a Mystery ISA Card

by seanellis9＠gmail.com

Hey all, I got this (currently exploded) mystery RAM, RTC, and I/O board out of a dead Sanyo luggable the other night, and once I replace the burned up tantalums I'd like to put it in my 5150 so I can get a full 640k of RAM. Question is, does anyone know what this board is? It's a completely anonymous board with not even an FCC ID to go off of. I'm assuming the RAM is at least strapped right; all the banks are full which should be 384k, and the Sanyo was a 256k machine = 640k. Here's a couple pictures; one's an actual picture of the card and the other is a simplified TULARC/TH99-esque vector of what's on the board. https://i.imgur.com/WhO4cco.jpg https://i.imgur.com/uBCkv5G.png

cctalk Digest, Vol 73, Issue 13

by athornton＠gmail.com

I agree that whether a student learns has much more to do with the student than what in particular they're studying. I quit my undergraduate physics degree when I had a moment of clarity that even if I managed to squeak through my Partial Differential Equations class with a C (I did) I'd still be on a trajectory where _solving PDEs was what I would be doing with my life_. My undergrad degree is in Ancient Mediterranean Civilizations. My MA is in History (but, hey, the History of Computing). I dropped out of the Ph.D. program I was in for a variety of reasons, to be honest crushing depression probably chief among them, but also because I was a fairly decent practitioner, and I had more fun playing with computers than I did writing stories about people who'd played with computers a couple generations before I had. It being the late 90s, my job prospects were decidedly better on the Not A Professional Historian side of the fence. That was 22-ish years ago. I'd been making beer money all through college and grad school with IT jobs, and I've stayed in IT-related fields ever since. Consulting, systems administration and engineering, these days software development-but-also-devops. My lack of appropriate degrees probably only didn't hurt because I started a not-unsuccessful consulting business with my mentor after I quit grad school, and by the time I was ready to move on from that, I had enough years of broadly varied experience under my belt that it didn't really matter. But that's tangential. The actual point was: the fuzzy stuff is only contemptible if you've got Physicists' Disease. History is hard, and it has a lot more in common with debugging that is obvious at first glance. In both cases you are presented with "Here's what happened," and it's your job to figure out "why?" In both cases, the ability to break the end-state down into a set of much smaller components which contribute to it is key--and although that ability probably _does_ have a lot to do with innate personality or preference, it's also very, very much a learned (and trained!) skill. The thing with debugging is that you usually are afforded the opportunity the repeat the experiment while changing parameters. With history, you're not so lucky, and thus you never _really_ know the root causes (you also usually don't know "what really happened", but by cross-referencing your sources you may be able to emerge with some sort of decent-consensus guess), but you can make more or less plausible and persuasive hypotheses about them. The idea that you are interrogating a recalcitrant witness is common to both history (and I would guess many of the humanities and social sciences) and creating and maintaining working software. I'll grant that it's _harder_ to surf blithely through an engineering degree than it is through a liberal arts degree, mostly because there are less-subjective metrics (particularly in lab courses) as to whether you actually learned something about what you're supposed to be doing. If I were being snarky, perish the thought, I'd say that the engineers who didn't really want to understand what they were doing were pre-meds. Nevertheless, a degree--and particularly an advanced one--is indeed much more about the discipline to put your head down and swallow what's put in front of you than about smarts. I was told a couple of decades ago I'd regret not having stuck it out for my Ph.D. I'm still waiting for that regret to kick in; in the meantime, many others have come and gone. Adam
