Hi. Got a PDP-11/34 today. It came with a RK05, a Tektronix 4012 + hard copy unit and a Western Peripherals TC-130 9 track tape controller. Unfortunately I had to leave the actual tape drive behind. No space left on /dev/car and way to heavy for my herniated intervertebral disk... The tape drive was some kind of Cipher 800/1600 BPI drive. There was printed "MOD NO 0920640-1250U" on it. I couldn't find anything usefull on the net with this information. Now the problem: I own a Cipher 880 9 track tape with Pertec interface. It works well on my QBus VAXen and the PDP-11/73. So I am used to the 2 x 50 pin cables / connectors found along the Pertec interface. But the TC-130 tape controller has one 50 pin cable labeled "control", a 26 pin cable labeled "read" and a 26 pin cable labeled "write". There are two connector adapters to adapt the 26 pin cables to 36 pin connectors. I found the TC-130 manual on bitsavers. From a quick look at the signal names the interface of the TC-130 is not Pertec. But what else? Is there any way to connect the TC-130 to my Cipher 880? -- \end{Jochen} \ref{http://www.unixag-kl.fh-kl.de/~jkunz/}

MINC-11 boot problems

by james＠machineroom.info

Hi all, I obtained a MINC-11 from Adrians DEC emporium(aka garage) in Cambridge last year (http://www.binarydinosaurs.co.uk/museum/digital/minc/index.php). I've finally got around to taking a look and it appears to be complete and original with a /03 CPU. Taken all the cards out and given it a good clean. Checked for any odd washers etc. in the backplane. Removed the power supply (H786), hooked up to a pair of hard drives as a dummy load and tested. Nothing. Normally at this point I'd scrap it and hook up a PC PSU but I've been reading this group too long and have been persuaded by Tonys component level repair arguments so I got stuck in :) Tracked it down to one of a pair of 1N4004s connected in series after the 7912 12V start-up regulator. So, I now have healthy 5V & 12V supplies and these seem to be stable for a long time with all the cards in place. But - it's not booting. The diag LEDs on the BDV11-YA constantly read 1001 from power on (I'm assuming that on=1). The only table of diag codes that I could find lists 1001 as "DECnet message received" which I believe to be bogus since I don't have any DECnet cards (I'm also wondering if the MINC has different diag codes?). So I started digging further and found that BDCOK H is ~1.7V and BPOK H is ~2V. Now, I believe that these signals are generated directly from the PSU, specifically the power monitor board that calls them DC L and AC L. My assumption is that these should both be at 5V in a healthy system since they are active high - correct? Unlike a regular LSI11 the MINC doesn't have any front panel buttons or LEDs (e.g. for BDCOK status) so I can't easily tell if what I have is good or not... I've not gone too much further yet but thought I'd try and get some knowledgeable input to make sure I'm not going down the wrong path. One thing I have found is the -12V supply that's only used inside the PSU (and feeds the power monitor board) is at ~-15V. Many thanks for any advice! James

Anyone have experience working on Apple 800K drives?

by aek＠bitsavers.org

The top head mechanism seems exceptionally fragile. I went though a stack of drives where most of the metal flexures have bent up so the head no longer makes contact with the media. Sony doesn't seem to have done a very good job of the mechanical design on this.

RD53 Stiction

by robert.jarratt＠ntlworld.com

I have an RD53 which is suffering from the sticky bumper problem. Normally I can resolve this with a sliver of paper placed over the sticky bumper. But in this instance it seems the bumper has practically liquefied and I think it has gummed up some of the mechanism. Is it feasible to dismantle the assembly to clean it up? Has anyone ever done this? Any advice? Thanks Rob

New in collection: HP-85a

by oe5ewl＠gmail.com

Hi folks, today I got a HP-85a for my collection (got it from a workmate whose father died recently). It's in good physical and optical condition, very little signs of use. With the machine came 2 tape carts, one 16k mem-board, a spare roll of thermal paper, the user manual and a BIG carrying-case for the machine and the parts. After a quick check (psu) I turned the whole thing on and - whoopee, it's behaving like as it was new :D Sorry for the spam, but I wanted to share my happyness.

What is Fast Diagnostic Mode?

by robert.jarratt＠ntlworld.com

I got given a third party (Phillips) 32MB module for my VAX 4000-200 recently. I have just installed it. While it seems to work I get this from the console: >>>sh mem Memory 0: 00000000 to 00FFFFFF, 16MB, 0 bad pages Memory 1: 01000000 to 01FFFFFF, 16MB, 0 bad pages -- FDM (fast diagnostic mode) not working Memory 2: 02000000 to 02FFFFFF, 16MB, 0 bad pages -- FDM (fast diagnostic mode) not working Total of 48MB, 0 bad pages, 120 reserved pages >>> What is FDM exactly? I suppose it is a feature that is not present on this board as it is 3rd party, but I wonder if it can have any impact beyond affecting diagnostics? Thanks Rob

Alphaserver 1000A power supply shutting down

by CCTECH＠beyondthepale.ie

I have an Alphaserver 1000A which began intermittently halting, same as if the halt switch had been pressed. At the time it had a serial console. I thought it might have been picking up noise on the serial line and interpreting it as a break signal so I changed over to a graphics console. It still halted intermittently. This problem either went away or the following problem caused me to not notice it any more. The machine started intermittently powering itself down, requiring it to be switched off and back on again to reset the power supply before it could be run again. The machine might stay running for several hours or it might power down less than a second after switching on, or anything in between. Thinking that the two problems might be related, I investigated the operator control panel on which are mounted the low voltage on/off switch and the halt switch. I found the two switches to have little in common and my theory to be unlikely to be correct. The on/off switch and associated circuitry appear to be working correctly, as does the interlock which cuts power when the lid is removed. I tried a power supply unit from another Alphaserver 1000A and found this did not cure the problem so I replaced the original. Thinking that the power supply might be sensing an overload, I disconnected the power feeds to the disks/cd/floppy and removed all the PCI cards. The problem was still there. When it was failing regularly, I found a line going to the power supply which normally sat at 0V and pulsed high just as the power supply shut down. This line did not pulse the same way when the power was turned off normally. I suspect it is a signal from the system board to the power supply requesting it to shut down, or less likely, a signal from the power supply to the system board signalling it has a problem and is about to shut down. I have a service guide which mentions the possibilty of the power supply shutting down due to a fan failure or high temperature but it doesn't give any details on how this works or even how to find out if it is happening. Does anyone have any detailed information about the power control system in the Alphaserver 1000A or any helpful suggestions? Regards, Peter Coghlan.

Tandy 102 display fault

by jules.richardson99＠gmail.com

I managed to scavenge a Tandy 102 earlier today (1988 build, 32K memory). Physically it's in good condition, and powers up, but the display's a bit unwell, having an entire row of dead pixels 4 up from the bottom, and a 32-pixel high column of dead pixels 22 pixels in from the left (on just the lower half of the screen, the upper 32 in that column are OK). The fault seems a little bit more subtle than that, however; sometimes (depending on which app I'm in, and the angle of the screen, and what I type) I can see some garbage in the first two characters (12 pixels) of the dead row - usually much fainter than normal "on" pixels (barely even visible), and occasionally a fully-on pixel, but at the wrong x-offset for whatever I've typed. Question is, where to point the finger? I've no idea how the 102 addresses the screen, although when I was checking it over inside before powering on I noticed all of the HD44102 ICs - are each of these responsible for a small rectangular area, or is the relationship between them and their pixels more complex? Could a fault with one potentially knock out / corrupt an entire display row? Does anyone have a simple BASIC listing for a main memory check? That could be useful (one particular reason for mentioning that is that when I first powered the machine up, it had a non-default date and showed some files present, but in trying to scroll through the contents of one it reset, lost the files, and set the date back to 1900). I already re-seated the cabling between display and the main logic board; the cable itself looks to be in good condition with no signs of severe distress, but I'll check the individual lines with a meter just to be sure. cheers Jules

But in my experience with dozens of PETs and AIM65s, some working in extrememely hostile environments, I found that a remarkable product called Stabilant-22 almost totally eliminated contact problems (unless there was actual damage), and virtually eliminated frequent socket-related service calls. I don't recall having to replace a single socket; the only issue with certain socket types is that with a lot of vibration or circuit board flexing the chips sometimes migrate out of their socket. It's expensive but it does work and a little goes a long way.

[TRS-80] Reviews of TRS-80 and compatible computers in magazines of the 1970s & 80s (fwd)

by geneb＠deltasoft.com

[This showed up on the TRS-80 list that I'm on. I figured many of you here would enjoy it. -g.] ---------- Forwarded message ---------- Date: Sat, 16 Jul 2011 09:01:17 -0000 From: Rainer <fredrich at .......de> Reply-To: TRS-80 at yahoogroups.com To: TRS-80 at yahoogroups.com Subject: [TRS-80] Reviews of TRS-80 and compatible computers in magazines of the 1970s & 80s For some TRS-80 fans it may be interesting to have a view on the editor's judgements from the earlier times when these computers were displayed in computer shop's display windows for sale. The technical details of the reviewed computers are more precise and meaningful than the shorthand technical specifications found on modern computer museum internet sites. Some of the reviews are more well disposed and other less. Because of the different views of the various editors the reader can make himself a pretty good overview about the desired computer model. Since some of the reviews are difficult to obtain nowadays I think it might be useful to make them available in this manner. Beside the elder TRS-80 computer enthusiasts (I'm 51 years old) which are familiar with most of the TRS-80 models since the late 1970s there may be younger ones who could be supported in their decision to obtain a specific model. The containing information of the reviews might bring some light in the beginner's lack of knowlegde of the different types of TRS-80 and compatible computers. BTW, are there any younger TRS-80 users among us (born after ~1980) or do the group members consist only of survivers of the former 8-bit times? The reviews are taken almost all from independent magazines like Byte or 80micro and similar printed publications. The pages from the magazine 'Microcomputer News' should more seen like an introduction and advertisment than real reviews because this magazine was published by Radio Shack. Nevertheless I have added for completeness a few of the overviews from this magazine too. Some of the models have more reviews than others. That's because my access is limited to only a small fraction of all ever printed issues of the various computer magazines. For example: the Model III which is represented only by one review is accidently the least recognized computer in this collection despite the fact that this model is one of the most spread ones. Does someone have another review of the Model III? I've collected all the reviews found in magazines that I have (had) personally on paper or that are (were) accessible in digitized formats (PDF, JPG or plain text) on the internet. Regardless of the original data format all the reviews are now in PDF. Featured Tandy Radio Shack computers: - TRS-80 Model I - TRS-80 Model II - TRS-80 Model III - TRS-80 Model 4 - TRS-80 Model 4P - TRS-80 Model 12 - TRS-80 Model 16 - TRS-80 Model 16B - TRS-80 DT-1 - TRS-80 Color Computer Featured TRS-80 compatible computers: - PMC-80 - Dick Smith System 80 - Video Genie - Lobo Max-80 - LNW80 - Trommelschlaeger TCS GENIE IIIS - Trommelschlaeger Speedmaster The examined magazines (nearly all in English language exept the mentioned German magazines): - 80micro - Byte - 80-US - Microcomputer News - Creative Computing - Infoworld - Micro-80 - CHIP (German language) - c't (German language) - Computer Persoenlich (German language) The reviews of the specific models are integrated to sets of PDF files and packed in RAR archive files. To unpack the desired file you can use the program Winrar for example. Other packing programs like Winzip may work as well. For more information look at: http://en.wikipedia.org/wiki/RAR_(file_format) The sets are named: TRS-80_Model_I_Reviews_(Version_YYYY-MM-DD).rar TRS-80_Model_II-12_Reviews_(Version_YYYY-MM-DD).rar TRS-80_Model_III_Reviews_(Version_YYYY-MM-DD).rar TRS-80_Model_4_Reviews_(Version_YYYY-MM-DD).rar TRS-80_Model_16_and_Terminal_DT-1_(Version_YYYY-MM-DD).rar TRS-80_Compatibles_Reviews_(Version_YYYY-MM-DD).rar Color_Computer_Reviews_(Version_YYYY-MM-DD).rar Additionally for the interested party that like to have all reviews a RAR file is available that includes the whole collection: Tandy_Radio_Shack_and_Compatible_Computers_Reviews_(whole_collection)_(Version_YYYY-MM-DD).rar A set's version date (Version_YYYY-MM-DD) is updated every time a new review is added to the set. The first version date of all sets is 2011-07-12. Coming updates will be published here. Each archive file is stored on two different file hosting services for downloading. You can choose your preferred file hoster. The files are usually deleted by the services after a period of 30-60 days without a download. Please let me know if a file isn't accessible anymore. See below for the download links. Have fun with reading. Additional contributions of reviews and any comments are welcome.

PDP-11 on an S-100 Card

by lynchaj＠yahoo.com

PDP-11 on an S-100 Card Steven M Jones classiccmp at crash.com Thu Jul 14 19:00:45 CDT 2011 Previous message: Seeking Morrow MPZ80 rev3a PALs Next message: PDP-11 on an S-100 Card Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] There was a thread here or on the N8VEM-S100 list about putting different vintage CPUs on a newly designed S-100 boards. I happen to be cleaning up my office and came across something done back in the day worth noting on that theme... In the May 1984 issue of Microsystems, /The Journal for Advanced Microcomputing/ (Vol 5, Num 5), there is a directory of S-100 products. ABACUS Technology Systems, Inc is among the vendors listed, and on page 67 they have a 1/4 page ad for their PC11 product - right next to a similar ad for the Lattice C compiler. This board features a T11 with 32KW of RAM, and runs RT-11 v5.0 with compatible I/O devices emulated somehow by a CP/M program (presumably running on an 808x/Z80 card in the same chassis). Here's the full text of the ad: [snip] -----REPLY----- Hi! It was on CCTALK mailing list the S-100 PDP-11 was discussed a few weeks ago by the people here. My offer to build a board still stands but it will take some effort of someone(s) who can design the schematic and write the software for whatever free/open source software is necessary. As I recall, the project fizzled since the obstacles to overcome were simply too enormous. That's a shame however if someone gets ambitious and wants to take this on please let me know since I'll volunteer to make the PCB, get some prototypes, etc. Thanks and have a nice day! Andrew Lynch

Terminal server advice

by bdwheele＠indiana.edu

Hey all! I'm planning to upgrade my home network at some point in the not-too-distant future and I'm trying to figure out what to do with my serial-terminal-console machines. Right now I'm using a decserver 200/mc to connect to them, but its always been a little fragile: It doesn't seem that most switches understand MOP (so it won't boot) and requiring a lat client leaves a lot to be desired. The connected serial terminal works great but parts of me are wanting to move to something that takes up less space and is more tcp/ip friendly. What is everyone else doing for this? Just a back of the envelope count looks like there are around 8 serial-consoled machines. I've thought about using usb-to-serial adapters but that seemed kind of hacky. The machines are a mix of OSes, and some of them are Suns, so the break/disconnect signal is always...amusing. If I can ditch the mop requirement I should be able to get rid of my aging (and noisy) hub and move everything to switches (since I don't use decnet either) Anyone have any suggestions? If I can get a reasonable solution I'll probably get rid of the pair of ds200's I have (one with skins and the other without). Brian

Disc for "The SCSI Bus and IDE Interface" (Schmidt)

by classiccmp＠philpem.me.uk

Hi guys, Does anyone have a copy of the floppy disc (or possibly CD) which accompanies the Second Edition of "The SCSI Bus and IDE Interface" by Friedhelm Schmidt? I just bought an ex-library copy of this, and the disc is naturally missing. The local library is showing their copy as "Sold/disposed, content no longer relevant"... Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
