I know some folks have been trying to get in touch with me for a while and I want to apologize for not getting back in touch with folks before now. The short and long of it has been the fact that first my wife had health issues, then I had health issues and finally in the middle of all of this my ISP decided to move me to a new static IP block which caused my email to be on various black-lists that took a while to get off of (so I could *see* the emails, I just couldn't respond). So, that's why folks haven't heard from me. Up until the above, I had been making steady progress on the MEM11 code. Right now I have most of the forth code written along with a J1 simulator (written in forth). I was in the process of debugging the simulator when all of the above occurred and I haven't been able to get back to it yet. I hope to start on it again in the next few weeks. TTFN - Guy

Front Panel Tech Note 2

by jnc＠mercury.lcs.mit.edu

> From: Pontus Pihlgren >> Seeing the one with the one with the missing toggle switches reminds >> me that I have an enquiry out re getting some made. > I believe many would appreciate that. We probably ought to standardize our terminology to be slightly less confusing. As we've determined, the actual switch is a slide switch, not a toggle. I'm not sure what the official DEC name is for the plastic lever which actuates the slide switch - anyone know? Noel PS: If a way is developed to make the plastic levers, the 11/20 uses the exact same part, just in PDP-11 colours.

Intel MDS-740 hard disk documentation wanted

by spacewar＠gmail.com

Does anyone have documentation for the Intel MDS-740 hard disk system for use with the MDS and Series II, Series III development systems? The drive had one fixed and one removable platter, the removable being a 12-sector 5440-style cartridge. The drive may have been a CDC 9427H, or something similar. The controller was two Multibus boards, a 3000 bit-slice based channel board, and a drive interface board. (Similar organization to the two-board floppy controllers.) I am mostly looking for the schematics and programming information, though if anyone has an actual controller board (or even just the channel board), a dump of the microcode would be useful. The documentation I'm looking for might or might not be contained in the "Model 740 Hard Disk Subsystem Operation and Checkout" manual, order number 9800943A. Note that this is *entirely* different than the iMDX 750 winchester disk subsystem. The 740 was supported by plain ISIS-II 4.x, while the iMDS 750 used a variant of the iSBC 215 controller, and required a special ISIS-II(W). Thanks! Eric

Opening up a TeleVideo TPC-1

by isking＠uw.edu

Hi folks, I was in an antique store today, mostly to humor my wife, and much to her dismay spotted a fairly early luggable: it said TeleVideo on the face and, looking closer, it was a TPC-1 with the keyboard, the carrying bag, the documentation AND a metric butt-ton of floppies. Once I get everything sorted I'll let the list know what software I have, so if you need something maybe I can help.... ...and maybe you can help me. I want to open up the TPC and check power supplies, etc. - OK, I'll come clean. I plugged it in, watched carefully for magic smoke and, seeing none, put a 'working disk' in the drive. I got an endless string of '.' but no boot. I tried a couple of other disks labeled <boot> and, after a couple, I no longer had a display. So no surprise, I really need to open it up and probably replace a bunch of PS capacitors. I have no idea how to get this box open! There's nothing in the documentation, and I found one online reference that suggested TeleVideo kept this information close to the chest because they didn't want any Tom, Dick or Ian opening up their machines. Now if I poke and prod long enough I'll probably get there, but with the collective knowledge on this list I figure there has to be SOME one who worked on these back In The Day, who just knows this off the top of his/her head. So... anyone? Thanks -- Ian -- Ian S.

SS10 console settings

by tmfdmike＠gmail.com

Folks, I'm trying to resurrect a couple of Sparcstation 10 systems. Is there anything 'funny' about the serial console settings on SS10 hardware? I thought they always defaulted to 9600-n-8-1, but I get voluminous gobbledygook at that, and at every other baud rate I've tried. Both systems behave identically, so I can't assume SS10 settings are wrong. And I *am* getting data, so I don't see how it can be the cabling. Something strange about the terminal emulation mode required maybe? Thanks Mike http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother.

Yet another way is to use BACKUP /NOASSIST - this should avoid issueing OPCOM messages and prompt the issuer of the BACKUP command directly when tapes are to be changed and so on. The standard way of doing backups on VMS is to submit a BACKUP command in a batch job. The operator would normally be logged in interactively and would respond to the OPCOM messages from the batch job and deal with tape mounts. This requires a suitable batch queue to be set up and started. Regards, Peter Coghlan.

John - Ref your 8S below - Happy to add this to the list. any other good background info as to prior users etc? yes if you can get the S/N will add that. I need to get the S/N of the SMECC one too I will have to take 3 helpers over to warehouse to exhume it. I will also get the S/N on the classic 8 in blue cabinet (alas missing its front desk) heck I may just try to fit that in the Mini Room at the museum too with the glassed in cards table top that is there. There is also a spare front panel assembly for a straight 8 there that I remember putting there 20 years ago may have crack in corner way towards edge though and has switches cables etc... No promises but it should be there ( an no promises how log it will be to get it out!).. Is there anyone out there that needs this assembly? something totally off topic from the 8S machines there are some trs80 radio shack things that are huge like the MODEL 2 was but these were later and had a 3 number designator ? there are many as I remember one will be kept another kept for offsite displays but the others will goooooooo........ sorry to do so many messages in the 8S topic thread tonight but I was asleep for a day with massive migraine and am trying to catch up.

Coating on older DEC slides

by jnc＠mercury.lcs.mit.edu

So I have a bunch of older DEC slides (for BA11 boxes, RK05's, etc) which are rusty. No problem, I have a sand-blaster, but.... what's the grey coating on them, and how do I reproduce it once I have them clean? I saw Corey Cohen's really wonderful presentation at VCFE about restoring old computers, and afterwards I asked him if he knew anything, and he said that (from my description - alas, I didn't think to show him one in the display area) it sounded like a powder coat thing, and that people who do brake calipers can do power coating. However, when I went to my car guy for pointers to local people who do brake calipers, he looked at the coating, scraped at it a bit with a knife, and said it didn't look like powder coat to him. (Although maybe this is a very old powder coat, and he's only used to the newer stuff.) He reckoned it was just grey paint {visualize dubious-looking Noel - it sure doesn't look like paint to me}. So, what _is_ that grey coating - and, more important, how (if at all) can it be reproduced these days? Noel

It probably hasn't hit the pagefile yet. > > It appeared to be trying to create or join a > VAXcluster for a while, then said something about loading MSCP disk server. > Before you do anything, make sure the ethernet network is properly connected or terminated appropriately. If configured to form a cluster, VMS will normally wait for a short period for the other cluster member(s) to appear on the cluster interconnect (usually the ethernet network) before continuing to boot. Try leaving it for a few minutes and you may then get something like: "VAXCluster state transition completed. Initialization continuing". Or you might not. In a cluster, each node contributes a number of votes to the cluster. None if the nodes will do anything until a cluster quorum is present (more than half the number of votes usually present in the cluster). If the machine just sits there indefinately after loading the MSCP disk server, you probably don't have enough cluster votes to proceed and the best thing to do is perform a conversational boot which usually involves setting the least significant bit of register R5 to 1 before booting. How exactly to do this varies from processor to processor and I don't know how to do it for an 11/730. When you manage to do this and try booting again, you should get a "SYSBOOT>" prompt and you could: SHOW VAXCLUSTER SHOW VOTES SHOW EXPECTED_VOTES SET VAXCLUSTER 0 SET WRITESYSPARAMS 0 CONTINUE to confirm that the issue is with cluster votes, turn off clustering and proceed with the boot process. > I have plenty more experimentation ahead, including seeing what's on that > RL02 pack labeled something like "VMS53SYS" (if I recall correctly). > > My attempts to boot up the v5.3 standalone backup tape images I downloaded > still haven't succeeded.

This is likely newer than when the 11/730 was sold but I suspect that many an 11/730 would have been upgraded to this version while in service and ended their days on that version. It was regarded as a good stable place to be with few unaddressed issues and it would be increasingly difficult to get useful items such as a stable TCP/IP stack running on versions earlier than V5.5-2.

Looking for the Tek 465 of Logic Analysers

by seefriek＠gmail.com

Thanks for the input everyone. In summary, I got recommendations for: - HP 16500C (lesser a 16500B, but not a 16500A) (mainframe) - HP 16700/16900/17500 (mainframe, bigger-faster-stronger, still pretty expensive, can use 16500 cards) - HP 166x or 167x (portable, modern, look for hard drive) - HP 165x (portable, older, only buy cheap, look for hard drive) - HP 1630D, 1630G or 1631 (old, HPIB and HPIL interfaces, no special software needed, but you apparently need be able to control it with an external HPIB controller to get the most out of it) - Tek 1240 - Gould Biomation K100D (software in rom, HPIB interface, assuming you need HPIB literacy to use effectively) - Tek DAS9200 (be careful to get the right pods (several variations), etc) - Tek TLA710/TLA720 (PC attached, Linux capable) General advice offered: - Look for hard drives or no special software required for longest life. Floppies required == bad. - Make really sure you get probes, and the right probes, for your kit. They're often not available separately for non-st00pid money. - There's a crazy array of ancillary features to consider: o-scope functions, processor assemblers/disassemblers, pattern generators, specialized inputs/outputs, timebases, embedded Unix machines, etc. Know what you might need. So I've got a lot of manuals to read, but the 16500C sure looks like a ton of bang per US$. You can even get an expansion chassis (10 additional slots) if you need to go to ludicrous speed on the number of probes/features. KJ

TRS80, other than model 1

by COURYHOUSE＠aol.com

Fred and others - I stand corrected these are probably model 12 or maybe model 16... did they network the Xenix ones? maybe that is why there are many of them. I recall one large RS printer was with the group? Guess I should have looked closer last time I was in that area. on another topic we need trs 80 model 100 to give the college to go in the tools of the journalist display need not work just look nice.. reporters used these for field reporting . If you think about it many things are 'a tool of the journalist" gosh! we endowed them with candle stick phones, some various other old phones, old pens, old typewritters, studio and portable video cameras, video recorders in many sizes and formats ... the list goes on!

In addition to the model 1, . . . The model 1 line was converted from a "component" system to a single box. For those not familiar, it resembled a Northstar Dimension. Keyboard, screen, two 5.25" floppies in a terminal like case. That was the model 3. Default disk format was double density. Since the WD 179x controller could not write a truly exact model 1 format single density disk (did not support certain data address marks), there were some kludges and changes in TRS-DOS, so there were minor glitches in the "upgrade path". Radio Shack eventually cut a deal to market L-DOS as TRS-DOS 6. ("And Randy Cook is now finally collecting royalties!") Soon, the model 4 was made available - same basic machine with 80x24 video (V 51x16), green screen, a few missing keys provided, and ability to remap the ROM from the memory map. Finally, CP/M was available without memory remapping hardware, nor software kludge of having TPA not in low RAM. The college got a whole lab full of model 3's converted into model 4's, at a price per each that was only slightly more than buying new model 4's. Model 4P was luggable version, vaguely resembling early Compaq. Model 2 wasn't what I would call "huge", but such is relative. It was completely unrelated to model 1, other than name, and naming it's OS (mutually incompatible with model 1/3) "TRS-DOS". But, CP/M was also available. It had an 8" drive, and "huge" external case if you wanted more than one. Radio Shack came out with a 68000 CPU board! and Xenix It could be used instead of the Z80 CPU, or have BOTH! (12 and 16) In terms of "huge", there were a few other machines that rarely, if ever, actually made it to market, such as the "Tandy 10", built into a desk, and sold exclusively through "Radio Shack Computer Center"s. -- Grumpy Ol' Fred cisin at xenosoft.com

Sorry, I deleted the posts from earlier from someone looking for TVGA software. I have at least the TVGA 8900C Disk 2 Utilities disk, on 5.25" floppy. Disk 1 will probably turn up soon.

HP 3082A ("Industrial Touch") Terminal service manual or other info?

by derschjo＠gmail.com

Hi all -- The lovely HP 3082A terminal I've been using with my PDP-11/73 has started exhibiting odd/annoying behavior today. The 3082A is also known as the "Industrial Touch" terminal, it's a compact unit in a rugged housing with an EL display, built in keyboard, and a touchscreen. At powerup, it normally gives a few short beeps and starts normal operation. As of today, it gives one continuous beep for 31 seconds (I timed it), after which it works fine -- until the next time it needs to emit a beep (a ^G, for example) and then it beeps for 31 seconds again. This is, to be quite honest, intolerable :). The manuals on hpmuseum.net are limited to configuration/user manuals and the brief troubleshooting it recommends actually *does* mention the continuous beeping symptom, but gives no suggestions for causes, and suggests as a fix to (a) try turning it off and on again (I've done that...) and (b) replace the terminal (can't do that). I've also tried resetting the terminal config (hold down Help + . at powerup) and this has no effect. The terminal passes all built-in self tests. Anyone happen to have any experience with these, or know where a service manual might be found? If I at least knew what the 31-second beep signified I could start looking... Thanks, Josh

Collectors pay big money for old tech

by COURYHOUSE＠aol.com

Well ... some things really are not more expensive... the money is just worth less back when I used to buy pdp-8 computers for 100-200 dollars ... like 24+ years ago cars were a bunch cheaper too by far.... There are some things that went crazy like the Apple I but there is still a lot of interesting things around especially if you are willing to go out to sales and scrap yards etc. Then remember there is the 'art' of anticipating what will be considered a classic or totally cool and grab some on the time line point of near obsolescence and when others finally figure out it is cool... Two computers come to mind on that for us was Cobalt cube ( got a cobalt rack unit to keep it company too) and a Next cube system Ed# _www.smecc.org_ (http://www.smecc.org) In a message dated 6/13/2015 12:24:00 A.M.

Ebay GT-40 in the Netherlands

by jws＠jwsss.com

DEC-Digital-1972-GT40-vector-graphics-system-PDP11-PDP-11 http://www.ebay.com/itm/231477915161 If I could afford it I wouldn't sweat the shipping cost. I think someone had posted what board did the graphics. Has that ever been given consideration for being added to SIMH for the 11? I'd love to run Lander, which I think is running on the system as shown. To Al: There was also a system like this at USL, which I wish had been conveyed to you. I suspect it was not. There was a new in the box replacement CRT because someone had had the system halt and burned the phosphor. You had to watch the system and never let the dot stop. If it stopped at a spot on the phosphor in the on position, you'd etch the phosphor. Ours (USL) never ran anything but Lander, so until someone with a project came along, we were saving the tube. The burn didn't affect lander much at all. thanks Jim

VAX-11/730 %BOOT-F-Unexpected Machine Check

by cctalk＠beyondthepale.ie

> > The issue that I'm having at the moment is that when I try to boot from either > that RL02 pack or the R80, VMB.EXE reports "%BOOT-F-Unable to locate BOOT > file". I don't know yet whether there's something not-right about the > contents of the hard drives, or I need to configure something (?) so VMB.EXE > knows what to look for. There can be more than one system root on a VMS system disk, typically one each for different nodes in a cluster, maybe under [SYS0], [SYS10], [SYS11] etc and standalone backup can sometimes be found under [SYSE], if installed. "Unable to locate BOOT file" may indicate that you are not reading the correct system root or it may indicate that the disk is not bootable or maybe something entirely different. I am not well up on the 11/730 and I hope someone more familiar with their system specific details will chime in. On some other VAX machines but probably not an 11/730, the [SYSE] root would be booted by entering something like: boot /R5:E0000000 <device> or maybe: boot /R5:E000000 <device> or maybe even: boot <device>/E0000000 or boot <device>/E000000 > The boot scripts on the console boot tape appear to set up VMB.EXE by shoving > numbers into some registers prior to loading it, and I have not yet located > any documentation about what the numbers mean. If it is like other VAX variants that I am familar with, the top eight bits (or maybe four bits - I forget which?) of the 32 bit number that ends up in register R5 is what selects the system root you end up attempting to boot. > > I wonder if I might be able to back up the hard drives to an absurd number > of emulated TU58 images, so that I could then examine those on my modern > machine? > That sounds plausable.

Could it be related to me getting delayed second copies of stuff? It happens because there?s some older mail clients being used which incorrectly parse the email address and create the general at classiccmp.org address when replying. The problem with the duplicate messages is because messages from the cctalk list are also relayed to the moderated cctech mailing list, and vice-versa. What happens is the messages from cctalk go over to cctech, get approved, and then get sent back to the cctalk list. From my understanding of the mailing list software being used, it doesn?t have any built-in facility to prevent duplicates by checking for messages with the same Message-ID, and would require someone to spend a little time to cobble a helper script together, but no-one has yet, so the message duplication has continued for a year or so now. -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com

SET DEFAULT SYS$SYSTEM RUN AUTHORIZE MODIFY SYSTEM /PASSWORD=<new password> /NOPWDEXP /NOPWDLIFE EXIT LOGOUT Then login in.

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.

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.

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

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

Alpha 4100 CPU fan

by binarydinosaurs＠gmail.com

Folks, Trying to source a non-DEC fan for a 4100 CPU since getting them in the UK is more and more tricky as time goes on. The originals are 12V 0.17A 60mm 3-wire and I've found some almost-identical-but-not-quite 0.18A variants. Needed to rewire the plugs to match (12V, sense, gnd) but the machine reports 'CPU0 Fan Fail' despite the fact the fan is running at speed. Is +0.01A enough to make the monitor board think the fan's failed? Board itself is fine as it works with its existing fan.

Front Panel Update

by rodsmallwood52＠btinternet.com

Hi All Since I released the picture of the first 8/e panel on Friday there has been a big response. Its 12:45 local on Monday in the UK and I'm of to the silk screeners to collect the rest of the first batch and to arrange for more to be printed as soon as I get the blanks from the plastics supplier. I'll send out what I have to fullfill as many of the orders I have so far as I can. I have learned an awful lot just based on the inquires I have so far. I see the following as requirements 1. Full size reproductions of the original panels useing the same methods. 2. High quality 3. Custom one off service for important restorations. 4. There's more demand than I thought. 5. So far its all been for DEC systems And yes they would look good just hung on the wall Next up an accurate reproduction of the bezel. And after that a lamps and switches board when and if I solve the Stackpole switch levers issue. Please send in your orders so I can allocate production/shipping slots. Regards Rod Smallwood

WTB /WTT DEC TZ30 and/or 1/2" open reel SCSI magtape drives

by nf6x＠nf6x.net

In order to be able to move data between my vintage and modern computers more effectively, I am looking for one or both of these items: 1) DEC TZ30 tape drive. This is a TK50-compatible drive in a 1/2 height form factor with a SCSI interface. 2) 1/2" open reel magtape drive with SCSI interface. Preferably with 6250 BPI capability. Doesn't need to be fast or fancy; just needs to be working-ish. I'm located in Riverside, California, USA. For an open reel magtape drive, a local source would be preferable to avoid the need to ship the beast. Or possibly in Las Vegas, where my folks might sneak it into the moving van later this month... :) eBay and I are now seeing other people, so I'm cut off from that source. Ditto for PayPal, so I'd pay by some other means (or maybe even trade). -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/

Wanted: stand for NeXT monitor

by tosteve＠yahoo.com

Just acquired a NeXT 68040 cube computer. It's way cool, but the responsiveness is unimpressive - I'd call it pokey. All 16 RAM slots are full for 16MB, but sixteen 4MB RAM sticks may help the speed. It has an internal HD, as well as the magneto-optical drive. One things it's missing is the monitor stand - does anyone have a spare stand for a NeXT N4000A monochrome monitor? Thanks- Steve.

If you leave them on, the tapes at 58C, will often just fall right out the seal--the coefficient of expansion is much larger for the seals than for the tape reels. After the seal has had a chance to cool off, it fits fine. This is particularly a problem with the smaller size reels. --Chuck

We put some heat-shrink tubing on to stop further damage. Warren repaired and tested the M706 Teletype receiver. We put it back in the PDP-12 and put the borrowed M706 back in the PDP-8/I. The donor brought another M706/M707 pair, so we tested them and then installed them. We have two working serial ports in the PDP-12. Warren is making an Arduino based programmable baud rate generator for this system. We ran more diags. The 8/I Instruction Test #1 & #2, and the random JMP, JMP-JMS, ISZ tests work OK. The LINC Tape-Quickie test and the Memory Address test fail after running OK for a few minutes. We tested all of the G221 Memory Selectors, and they are OK, so the memory address decoding is probably working OK. This may be a case where the processor is sometimes doing the wrong thing when comparing numbers, and the rest of the hardware is actually OK. Debugging this will be the project for next week. The donor dropped off more documentation, spare parts, LINC tapes containing the DIAL operating system, and an RK05 disk pack that likely contains OS/8. We will make image copies of the LINC tapes and the disk pack. -- Michael Thompson

Worse, some of the ones I've fished out have utterly crumbled over the years, leaving bits of themselves inside the reel. I am curious: NOS tapes that I bought in the last year or so came with the foam blocks, but I don't recall ever encountering either a foam block or the magic plastic tape "back in the day" on tapes from the rack that I handled as a backup operator. I presume that if they came with blocks, they were discarded when the tapes were unpacked. Is it really necessary to secure the tape end in normal use, or is it just needed during shipping to keep the tape from getting loose on the reel during transport? -- Mark J.

Varian is a microwave equipment company; I have one of their TWTs sitting on my H960 at home. Vacuum equipment, I could believe that. But yes, Varian made a 16 bit minicomputer; I had a handbook for it at one time (now lost, I suspect). And if memory serves, the reason is that there was one in the Computer Science department at the University of Illinois where I studied. I remember nothing about the architecture, other than the fact it supported user microprogramming. Possibly the OEM PDP8 predates that device. Or possibly it wasn?t enough of a competitor for DEC to stop doing OEM business with Varian. paul

Blue tape retainers

by cclist＠sydex.com

I'm getting a little tired of replacing old dried-out foam blocks to hold down the ends of 1/2" tapes. Worse, some of the ones I've fished out have utterly crumbled over the years, leaving bits of themselves inside the reel. One thing that I recall is that many tape manufacturers used a blue, sort of "sticky silicon" tape to hold ends in place. This stuff never seems to degrade. Does anyone know what the stuff is and where one might get a roll of it? --Chuck

VAX-11/730 %BOOT-F-Unexpected Machine Check

by nf6x＠nf6x.net

I finally got the excellent AK6DN tu58em emulator working as my VAX-11/730's console drive, as discussed on VCF. The trouble appears to have been a simple timing issue: tu58em includes some time delays which run afoul of the 730 console's very aggressive timeout checking. After patching in a command line flag to disable them, my 730 console seems to be happy with tu58em running on my MacBook Air over an FTDI USB/RS-232 converter. I've also tweaked the FTDI's driver settings to make sure that latency is minimized, but I'm not sure if I changed it significantly from the default. But the console appears to time out if the tape drive takes 20ms or more to respond to the initialization sequence, so every millisecond might impact reliability. With the console working and loading up a version 57 11/730 console tape image that I found online, I've been trying to boot the machine up. When I try to boot from either the R80 or RL02, I get error message "%BOOT-F-Unexpected Machine Check". Does that error message mean anything to the VAX experts out there? This machine was believe to be working before time + transport, and I'm trying to bring it up for the first time since I got it. I still have a lot of learning curve to climb, but I'm excited to have made more progress. -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/

I remember a PDP11 (11/45 probably) at the University of Illinois, around 1975. It was used as a terminal controller for ARPAnet.

ARPA Network Terminal System. I've got an ANTS logo panel on the wall at home.

History of portable computers book -- pre-orders

by evan＠snarc.net

Hi all, I'm going to release "version 1.0" of my book in a PDF edition this Friday night. Then in a couple of weeks from now I'll release a Kindle e-book version and a print edition. The PDF version is only $8 and can be ordered right now at the very primitive web site: http://www.abacustosmartphone.com. There's nothing to stop people from sharing or posting the PDF, other than me asking nicely: please do not do that. I am releasing the book early because I need the money. So what's in the book? It is the story of the evolution of mobile/portable computers -- how we got from the abacus to the smartphone. I wrote it in plain English for general and mildly technical readers. There aren't a lot of tech speeds-and-feeds; it doesn't explain how the computers worked or how to program them. It is almost entirely about who made them, why, and how they all improved on each other to incrementally move the ball forward. I think it's interesting. Some parts are very funny. Most of all, it's a story that until never was never told. - Evan

PDP8

by useddec＠gmail.com

With all the traffic on 8 front panels, which sounds great, I was asked about letting a few of mine go a while ago. The plan was to test and configure to order. A few list members inquired about selling a few as is making it cheaper for them, and more educational. I thought about it, looked at some of my projects, my piles of junk, thought about it some more and said yes. I"m not sure who dropped the ball. Contact me off list if you are interested. I'll think about overseas. Thanks, Paul

I don't have an 11/20 (yet!), but I had a look at the KY11-A manual (no print set online, alas), and it does seem to show (pg. 19) a slide switch. Like I said, the 11/20 switch array looks exactly the the 8/E and 8/M ones (except for colour, of course), which seems to support that the actual switch is a slide. Anyone out there have an 11/20, and can give us definitive info? Noel

According to RFC-597, Illinois had both an 11/20 and an 11/50 (11/45 variant) running ANTS; other sites also ran it on an 11/40. > it had a custom logo panel for the top of the H960 racks, in red and > yellow, showing large ants crawling all along the cabinets. That could have been a local thing. At MIT, the first MIT-built LISP Machines, also housed in H960 racks, had custom logo panels reading "LISP Machine", with an illustration of a LISP two-part cell, with pointers (to other, un-shown, cells). I still have one... (the panel, not the CADR). Noel PS: In a previous message, I wrote "KA-11"; I meant, of course, 'KA-10'. Got -11's on the brain.. ;-)

> From: Rod Smallwood > The switches were made by a company in the US called Stackpole > ... > They are a normal slide type modified with a U bracket to allow the > attachment of a lever arm to operate the switch when toggled up and > down. Ah; the 11/05's (which is what I need switches for) use toggle switches (like I said, pretty much standard micro toggle switches, excepts for the front plate). I'm pretty sure the later 11's with complete front panels (40's, 45's, etc) used the same kind of switch. I was assuming all the PDP-x's of that era used the same front panel switch design, but apparently not. Or perhaps I'm mixing my eras a bit, and the slightly earlier ones all used the slide switch stuff (I just checked my KA-11 panel, and it uses slide switches). I think the 11/20 might have used the slide switches (its switch register looks just like the one on the -8M). Anyway, it seems like we all need both kinds! :-) Noel
