I'm toying with putting the "ultimate" classic Mac together, although I'm having a little difficulty pinning down the definition of what the ultimate representation of the type is, so was looking for a little input from Classic CMP'ers. I'm aware that there's a clear divide between Motorola and PowerPC CPU'd variants, so I'm going to plump for a PowerPC based version so that I can get access to newer hardware and use it as a kind of bridge system between my current computers and the more historic versions. In terms of hardware I have a lovely mirror-door G4 PowerMac I'm intending to use. I have the original media that shipped with this, so I can get 9.2.1 on it relatively easily. Are there any add-in cards (PCI) I should be considering? It has a built in Airport Card (possibly Airport Extreme?) although my home Wi-Fi is 802.11n or better with WPA2 so I'll just use Ethernet to connect it to my LAN. Was a gigabit ethernet card ever released with Mac OS 9 drivers? I have a couple of 600GB PATA disks that I can use with it, but has there ever been a SATA implementation that worked with classic Mac OS? Also, I have an Asant? ether bridge tucked away somewhere that I hope to be able to use to connect some of my older Mac OS boxen without Ethernet. In terms of the software - any top-line utilities or System Extensions I should look to get my hands on? What's the state of the art in classic Mac OS browsing nowadays, Mr Kaiser - is Clasilla still maintained? -Austin.

Building the Ultimate Classic Mac.

by COURYHOUSE＠aol.com

Liam, thank you so much for this information! I did not know about all the HACKINTOSH action out there! Good to hear that one system will use SATA drive > I will just have to find some old installable OS for it. The family of the deceased engineer that passed these on to us at the SMECC Museum project tossed most any paperwork or media , so we have what is installed on the system and of course for the diskless one we are empty handed. We we were out scrounging now I wish I had picked up more vintage MAC paperwork and discs now. We saved stuff related to the early MAC and of course ANYTHING we could find for the APPLE II. We do also have something that looks like an APPLE LISA but not the twiggi (sp?) drive model I have heard reference to. it turned on last time I tried but just a bunch of diddle crap all over the screen. (bogus contents of memory mapped video or!?? <this machine is a mystery to me I saw it when it came out but that is abut the only experience I have had with LISA remember I was a HP guy in the business days... I do remember going over to a store in Metrocenter in AZ and seeing one for the first time with a MOUSE on it! I was amazed... Again... thanks for the hints and help now and in the future.

There are very few, this one looks complete, or near complete. That said I'd figure though some of the higher prices such as the current PDP8/I and GT40 are setting for want of bids, they aren't that far from what you have to pay to get said systems on demand. This one may go for around the opportunistic price, and be lower, but $10 to $12k isn't going to be surprising.

DEC boards at recycler

by jules.richardson99＠gmail.com

I found various DEC (Qbus?) boards at my local tame recycler earlier. They're scheduled for preprocessing this evening (e.g. ceramic ICs pulled and diverted into different pile due to higher gold content), but I may be able to get them a stay of execution (as of now I've got about 2 hours in which to let him know before I'm awol for a family event). Anything below strike anyone as being worth saving (vs. common as dirt serial interfaces etc.)? I'm not sure at the moment if I can rescue the lot... M7957 M8189 M8192 M8061 x 2 M8044 x 2 M8190 M8043 x 2 M7961 M8067 x 2 M7856 In addition to those, a board branded Dilog CQ1610, another marked PXX-2 with four SC44077P ics in the center, and a memory board marked 980110014 containing 128 mmc3764 RAM ics. Also several Emulex boards which didn't contain anything that was obviously a part number (from memory a couple that were "full width" and three that were "half width") - I'm guessing they're probably tape controllers, but they might be hard disk. Working status unknown, but cosmetically they looked good. It sounds like the previous owner had complete machines which he split and scrapped at some point in the past, and this box of boards had sat around in his garage since. cheers Jules

Wanted: VT5x roll-around stand

However, the tray is a different story. But I have to admit, that my reference is only the VT55-FB on a roll-around stand. If the stand for the VT55-FB is identical to the one for the VT52, then the tray is not the original one. It is not a tray, but just a plate and significantly smaller, but not flat. I can take pictures on Saturday of my VT55-FB with original stand. Let me know, because I'd have to remove the VT (6 bolts, IIRC). - Henk

The HP150 had HPIB as standard. There was an optional card that added HPIL and a Centronics port. That Centronics port was a mess. HP decided to use female DB25s for the serial ports. So to avoid confusion they used a male DB25 for the Centronics port. Only problem was the PCB was laid out for a female DB25 using IBM PC pinouts. With the result that the male version ended up effectively mirror-reversed, strobe on pin 13, etc. There were, indeed, HP ISA HPIB and HPIL cards. From memory the latter (at least) will not run in any reasonbly fast machine (8MHz CPU clock tops?) There was also an HPIL card for the Integral (portable unix machine) but I have never seen it.

Epson QX-10, battery removal

by terry＠webweavers.co.nz

Hi Jules I found removing my QX-10's battery stopped the machines working. I tried replacing it with a lithium battery after disabling the recharging circuit but that didn't work either. The old battery doesn't show any signs of leaking so I just left it in there. I check all my machines with batteries once a year for any battery leakage so I'm comfortable with leaving it there.

VMS stability back in the day (was Re: NuTek Mac comes)

VMS is an enterprise-grade operating system, designed for serious production work. At the time VMS was conceived, Unix was a university product, used for teaching and research, not for heavy production work. In fact those early versions of Unix were completely useless for that kind of application - too limited, unstable, and no useful security features. No accounting at all, no useful batch functionality, nothing but the most basic kind of security and protection functionality etc. VMS was designed to compete with IBM mainframes and System/32-34-36 and the likes. In the early 80s I used both VMS version 4 and 5 and Unix version 7. The Unix system was used for program development, the VMS system for program development and running accounting software. The Unix system was fine for program development in a lab but far too unstable and insecure for running accounting systems in a corporate production environment.

There's a battery in my QX-10; anyone know if it's safe to remove it before it leaks (i.e. it's not responsible for storing any parameters which might be vital to system operation)? I think most of my machines which have batteries just use them for things such as TOD clock and so it's no big deal to remove them (and they'll run happily without), but I do also have various "unknowns" - of which the QX-10 is one. (I don't suppose anyone is working on a big list of machines with batteries in, which ones need consideration before removal, and which ones refuse to function without a battery present, are they?) cheers Jules

eBay MVII BA123 $99 - Buy It Now - Richboro, Pennsylvania

by glen.slick＠gmail.com

Don't see too many complete looking BA123 boxes show up on eBay and this one seems relatively cheap if you happen to be able to pick it up locally in Richboro, Pennsylvania. Plus a few boxes of VMS documentation too. http://www.ebay.com/itm/232013130536 (No personal connection to, or information about, this seller) I would grab this one myself if it was within easy driving distance. Someone should grab it.

The 20-pin connector on the M8190 (KDJ11-B) is configuration management, etc - the console connector is the 10-pin one (which uses the standard DEC later serial pinout, documented here: http://gunkies.org/wiki/DEC_asynchronous_serial_line_pinout if anyone needs it). The 11/44 console (and TU58) seem (from a quick glance at the prints) to use some odd pinout that is sui generis. Time to break out the soldering iron... Noel

ISO HP 2392 terminal and VT100 keytops

by aek＠bitsavers.org

Well, I accidentally ordered two VT100 tubes, so this weekend I tried to restore the one I have, only to discover the keyboard is missing 3 keytops ("</,", PF2, and PF4). If someone has one in their spares pile (missing other keytops..) in the US, I could use them. Also, I'd like to try to find an HP 2392 terminal with or w/o keyboard if someone has a spare.

Seeking RL02 cable transition connector

by ethan.dicks＠gmail.com

Asking for a friend... ;-) An old buddy of mine picked up a PDP-11/73 at auction and we just went over it tonight - cleaned out some spilled toner from some careless stacking in a warehouse, and looked over the RL02 on top and it all seems complete and good to go, except... the connector on the I/O bulkhead was broken off (the ears and screws remain) and the BC06R 40-pin cable is sticking out. The drive-to-drive cable is there and looks intact, but there's nothing at the CPU end to clamp it to. These get brought up from time to time as people refurb 1980s PDP-11s and such - The easiest place to get these from is dead RL02 drives, since there are two off them on the back of each drive. Does anyone have a loose one to sell? Also as mentioned from time to time, the part number seems to be obscure and buried, but it's a component in a C-AD-7012415-0-0 "transition bracket assembly", which appears to be this 40-pin ZIF connector attacked to a rack-mountable metal bracket. All he needs is the plastic bit, but if it comes attached to a bracket, then that's OK too. Yes, I know we can get him operational with a long 40-pin cable. I'd just like to replace the one missing bit. Thanks! -ethan

I haven't built or marketed anything myself but i believe if i understood ?correctly from several folks who have that vga was a cheaper choice due to licensing costs for dvi or hdmi at the time.? Not sure if vga is past that point or open but when keeping home brew kits cheap for us hobbyists every dollar counts. It would be interesting maybe as a Wikipedia page (thought there was one) to show which projects were out there and preferably which are still active. ?A shrinking but understandable issue when buying ?im batches with personal money in hopes that theyll sell eventually.

-------- Original message -------- <attempted phone technology snip> The thing about the Amiga was its wow factor -- I remember walking into Compucentre (Canadian chain) in the mid-80s.. and there's all the computers from 8 bit heaven and their 16 color graphics (if you were lucky).. and then there's this one computer on a pedestal featuring a totally real jungle cat prowling onscreen. It just blew the doors off everything else there, and I would go wanting for one for 20 years afterward (now I have 5 :)). Not sure a replica can revive *that*. </snip> Thats an awesome story and experience that unfortunately i agree is hard to relay to people these days. To see how great lots of classics were during their heyday in comparison to what was out is what made so many historic memories. I think its unfortunately harder for younger generation sometimes to put away their cinematic quality vr and experience vintage gaming for what it was. Graphics drawn by programming, music while gaming, going for blocks and blips to fully animated sprites and tracked music playing all while fitting on a floppy disk. Or even the wealth and size of the virtual text world at a terminal or personal computer. Preaching to the choir here but when i did finally get around to showing selections of systems at our past vcf it was a blast and i enjoyed showing some of the comparison of commodore to some pc ascii games but also being fair and switching out to some of my favorite dos games too as well as pointing out the crispness of the pc display for text making it a probable better system out of the box for staring at text all day. I miss closer vcfs :-(

IBM 360/30 in verilog (was: How do they make Verilog code for unknown ICs?)

What you can do (and I?ve seen it done) is define verilog modules that provide the functions of the IC and use that in their designs. I?ve seen at least two interesting classic computer recreations using this approach (re-implemenation of the CADR lisp machine in verilog and an IBM 360/30 in verilog). ROMs are easy (just instantiate a lookup table). PLCs are just combinatorial equations which are relatively easy with the verilog ?assign? statement.

DEC boards at recycler

by jnc＠mercury.lcs.mit.edu

> From: Jules Richardson > I just told the guy to hold off on execution and I'm going back in next > week with a view to just buying everything Good call. Most of those cards are worth something to someone. (E.g. I'd be interested in the CPU's, the RLV12s, the DLV11-Js, and the M8067s - which are MSV11-Ps. But I'll let others grab them all first, they'd only be extra spares, for me.) They usually sell for $30-$100+ (for the rarer ones, like the M8190 - that's the KDJ11-B, used in both the 11/83 and 11/84). If either the M8190 or the M8192 has the optional FPU chip, the FPJ11, that is worth big dineros. The only exception is the M8044 - those are pretty low-value (I use them only as test boards for working on broken systems), since they are Q18 _only_, and can't be mixed with Q22 boards. So maybe $10 each, for those. Noel

DEC items to either pick up, ship or drop off at VCF midwest

by useddec＠gmail.com

I have a big load of DEC items coming in within the next month or two, probably a 24 foot truck packed, and an even larger one one possible this fall. I already have a 25 foot storage unit costing me a small fortune, and will probably need another. I need to sell off as many boxes, boards and terminals, and printers. This includes numerous most Q bus boxes, all vaxes, and a few 8-E boxes without covers and maybe slides. I am trying to keep the weeks before and after VCF free of medical appointments. I should be able to drop off items there, ship most, including overseas. You are always welcome to stop by as long as its pre scheduled, and too many people at once could complicate things.I think the members who have stopped here in the past have had a good time picking and chatting. Please send me any requests off list. Thanks, Paul

DEC Permission to Copy Out-Of-Print

by jhfinedp3k＠compsys.to

I need to obtain a link to the DEC Permission to Copy Out-Of-Print manuals. Might it still be at an HP site? Specifically, while just the actual permission itself will be helpful, more important is to be able to show that it still comes from an official source. I saw the Permission Notice in the past a few times, but I never bothered to keep a copy. Did anyone at least keep a copy? I would imagine that bitsavers might have a copy, so that would at least be helpful. Jerome Fine

Connectors: Both contact surfaces must also be the same material?

by pbirkel＠gmail.com

Stated Tothwolf tothwolf at concentric.net: "Both contact surfaces must also be the same material or tin oxide will form on the surface of the gold plating and cause a major headache. This was a serious problem with 486 and earlier Pentium PCs with 30 and 72 pin SIMMs and it led to a number of lawsuits." Almost every DEC System Unit ("backplane") that I've ever seen uses tinned-contacts, yet the Modules all use gold-plated fingers. How does that situation jibe with the SIMM issue/experience? ----- paul

TI Silent 700 print mechanism mechanical issues, and Model 763/765 bubble memory notes

by spacewar＠gmail.com

I've now got a TI Silent 700 Model 763, and it is partially working. The previous owner said that the line advance wasn't working reliably, but that otherwise it was working. As I received it, the thermal print head is only darkening the top scan line of characters, and only partially. The intensity pot is already at maximum. The line advance is working, but carriage return is unreliable, which results in the carriage banging against the right side of the mechanism and getting stuck there. The horizontal carriage positioning is done by stepper motor with an encoder for feedback, so I'm surprised that it isn't smart enough to recognize that it can't home the carriage, and avoid ramming it into the right end of the mechanism. I was worried that the thermal print head might be damaged. I opened it up and found that it uses the solenoid line advance mechansim, probably the same as is documented for the early production of Model 743/745. (Later 743/745 use a stepper motor for line advance.) With power off, the carriage can be manually returned to the left side. There were two loose parts inside, a spring and a small knob. These apparently belong to the solenoid line advance mechanism, belonging on the shaft at the opposite end of the solenoid from the link to the pivot. There are screws on the left and right end of the mechanism, which when loosened, allow the printhead to be moved up and down relative to the mechanism. The Model 743/745 maintenance manual suggests adjusting that if characters aren't fully visible. I tried that, and could see a little bit more of the characters, but couldn't adjust it to get the characters entirely visible. I accidentally discovered that with a small amount of additional pressure against the carriage assembly, toward the paper path, the characters are printed fully formed, and (quite suprisingly to me) the carriage return works properly as well. If I can't get this working reliably, I may start searching for a 743 or 745 with the solenoid line advance mechanism, to try a mechanism transplant. (The mechanism with stepper motor line advance is not interchangeable, and requires a different circuit board. I'm not sure whether that mechanism was used in any model 763/765 units.) The Operating Instructions manual for the Model 763 and 765 gives information on 13 different commands which are accepted in command mode. They mention the TEST command, which performs a self-test, and the TEST INIT subcommand which resets everything to factory defaults. There's a TEST MASK subcommand not documented in the manual which allows examining or altering the bubble memory minor loop masks. When installing or replacing a bubble memory module, it may be necessary to enter this information for the new module, from the mask data printed on the label of the bubble device. Unlike the later Intel bubble memory, the TI parts (at least of the 92Kbit devices) don't have a specified dedicated "boot loop" to store the mask, nor do they have a defined synchronization pattern to provide a detectable home position, so the TMS5502/TMS9916 bubble controller chip has to ensure that the device is rotated to the home position on power down or power fail. The terminal firmware may be using a specific normal minor loop, probably the first or last loop, to store the mask and a sync pattern, but the TMS5502/TMS9916 don't provide any automation for that. The TMS5502/TMS9916 also require that the mask bits be provided in a bit-serial fashion at the precise times needed during data transfers; TI app notes show the mask stored in PROM with a counter for addressing, but the 763/765 terminal doesn't do that. I'm not sure whether they have dedicated logic for the mask, or whether it's being done by firmware. The TEST MASK subcommand is probably documented in the Maintenance Manual, which I don't have; the only reason I know about it is that a technician left a printout showing the TEST MASK output for this terminal between two pages of the Operating Instructions manual. The terminal uses a TMS9980 microprocessor, which is an 8-bit-bus version of the TMS9900, which can only address 16KB of memory. The terminal has five TMS4732 4KB ROMS, as well as some RAM, so there must be some bank-switching going on. The bubble memory modules for the terminal came in two types: 1) A large "discrete" bubble module with one 92Kbit bubble device and a whole lot of non-bubble-specific chips (presumably because the SN753xx bubble memory support chips were not yet available for production). Two large modules are fitted, to provide the terminal's basic rated storage capacity of 20K characters (actually up to 22,860 characters if 18, 36, or 72 character record lengths are used). This leaves no room for additional bubble modules. The modules show up to the TEST MASK command as modules 2 and 6. 2) A small bubble module with two 92Kbit bubble devices and the SN753xx bubble memory support chips. A single module provides the 20K (22860 character) basic rated storage. Up to four of these modules can be fitted, for up to 80K (91,440) characters. My terminal had two large bubble modules installed. A friend gave me three more large modules, which have been treated roughly, so they have bent pins and possibly damaged components. I have one small module that came from eBay some years ago. I haven't tried any of them yet.

Connectors: Both contact surfaces must also be the same material?

'Bounces'

by vintagecomputer＠bettercomputing.net

Just re-subscribed to cc-talk. I'm wondering if anyone has an answer on this - every now and again I get these warning emails about 'excessive bounces'. I have to click a link and then they go away for a while. But sometimes I get busy and forget.. and then the list unsubscribes me. No idea what 'excessive bounces' means or what I can do to prevent it from unsubscribing. Any thoughts? Brad

TV Typewriter reproduction

by vintagecomputer＠bettercomputing.net

Hey guys, Getting closer to the 'construction' phase of my TVT replica. I already built a mockup the case and reconfigured and painted the MDS keyboard I found to match the prototypes. I also got some 'natural' colored PCB stock and etched some boards. Pretty happy with the results. Hard to tell if I got the right color or not.. I notice in photos my boards look closer to the color of the original than they appear to me 'in person'. Anyway, I remember Nick Allen was kind enough to post that photo of his TVT unit - I meant to ask at the time, are there any more pictures of it, especially from underneath? Or is there anyone else out there with photos of original TVTs (not to be confused with the later CT1024)? I'm finding the few pictures I can find of assembled TVTs very valuable in answering assembly and part questions. The blog of my progress on my TVT is here for those interested: http://bradhodge.ca/blog/?cat=11 Thanks again! Brad

Even in a reasonably good atmospheric environment weird issues can crop up. I once evaluated an air handler controller which had worked perfectly in product testing, but once field deployed, had a very high failure rate. It was made up of two pc boards with a pair of .100" pin and socket board to board interconnects. The two boards were physically held together with 4 nylon snap-in standoffs. The lower board contained terminal blocks, modular connectors, and the power supply circuitry and the upper board contained the microcontroller, network circuitry, etc. The cause of the failures turned out to be fretting corrosion of the board to board connectors caused by vibration. Another contributing factor was that many installers were not installing all 4 mounting screws when mounting the controller inside the unit (these were field retrofitted controllers) but were instead only installing 2 screws in opposite corners. The fix was to replace all of the existing board to board interconnects, both the header and socket with parts that had 30 microinches of hard gold over nickel (the original parts had 15 microinches of gold) and to use a contact lubricant during assembly. Repaired boards were also to be installed using all 4 mounting screws. The vendor later redesigned the controller so it was all on a single board (while still admitting no fault, of course).

Looking for old connectors

by lehmann＠ans-netz.de

Hi, for rebuilding a circuit, I'm in need of 3 old connectors used on the original board. ###################### One is easy - J3 is a 2x10 pin 2.54mm connector which is still common today. But it is higher than the usual connectors. It has a hight of 1.5cm. If you search for the printed A-MP number (1-87456-6), you'll find the housing, but not the soldered clips used inside this housing.... http://pics.pofo.de/gallery3/index.php/S8000/S8000_boards/FINCH-Adapter-Boa… ###################### The next one is a power plug used on a CDC FINCH harddisk. The manual states, that the Connectors AMP 1-87270-1 or 3-87025-3 can be used. I guess this where connectors used with cables - but I need a connector which can be placed on a circuit board like this one: http://pics.pofo.de/gallery3/index.php/S8000/S8000_boards/FINCH-Adapter-Boa… ###################### The next one is also a power plug - but I have no idea about its AMP number or something: http://pics.pofo.de/gallery3/index.php/S8000/S8000_boards/FINCH-Adapter-Boa… http://pics.pofo.de/gallery3/index.php/S8000/S8000_boards/FINCH-Adapter-Boa… http://pics.pofo.de/gallery3/index.php/S8000/S8000_boards/FINCH-Adapter-Boa… Its counterpart is shown here and labled with AMP, but no number: http://pics.pofo.de/gallery3/index.php/S8000/S8000_case/Disk-Tape-Component… Any info on any of this connectors would be great...

server maintenance

by jwest＠classiccmp.org

The classiccmp VM will go down tonight around 10pm-ish CST. There is nothing wrong with the VM, but the NAS it's disks are on is having some issues. We've live-migrated all VDI's off that NAS except classiccmp's. Due to the size of those drives, they will migrate a lot faster if that VM is shut down so that's the route we're taking. I would expect it to be back up in the wee hours of the morning - at least that's what the guy doing the work tells me. Just fyi.. J

Besides the need to channel it in small quantities through "consignment", I know that I can't manage even that level of physical exertion. So, I'll probably just fill a couple of boxes with IBM Technical References, Windows Resource kits, etc. and end up with most of the rest eventually going to paper recycling.

word processor history -- interesting article (Evan Koblentz)

by c.murray.mccullough＠gmail.com

My first word processor was from Wang called ?Word Processor? and then IBM?s ?Displaywriter?. I tried ?Wordstar? originally called ?Wordmaster? but way too complicated. When desktop publishing came along WYSIWYG printing was made possible - the writer?s true handmaiden! In the microcomputer world, classic computing, it was ?Smartwriter? on the Coleco ADAM. Those were the days! Happy computing. Murray

HP 8510 network analyser

by hilpert＠cs.ubc.ca

So a friend tells me there's a maybe-abandoned HP 8510 Network Analyzer in the hallway of the engineering building of the univ. he works at. I presume it's a unit like this, as he says it's over a metre tall: http://www.ece.lsu.edu/emdl/facilities/network%20analyser.html I figure its a little too far large and too far away from my needs to take it on, but out of curiousity does anyone know offhand what processor they used in these? (I haven't looked in depth online). Cursory guess is its mid-90s technology.

Second release of the HP 3000 Series III simulator

by jdbryan＠acm.org

The second release of the HP 3000 Series III simulator is now available >from the Computer History Simulation Project (SIMH) site: https://github.com/simh/simh This release adds a simulation of the HP 2607, 2613, 2617, and 2618 line printers and supports the use of custom VFU tape images, as well as the built-in HP-standard VFU tape. The full set of configurable options is detailed in a new section of the HP 3000 Simulator User's Guide that is provided in Microsoft Word format in the "doc" subdirectory of the code base snapshot downloaded from the github site. A PDF version of the updated manual is also available at: http://alum.mit.edu/www/jdbryan/hp3000_doc.pdf In addition, the preconfigured MPE-V/R disc image available from Bitsavers: http://www.bitsavers.org/bits/HP/HP_3000/ ...has been updated to add the following features: - The MPE cold load command files attach the line printer to the "lp.txt" output file and specify the "-n" option to clear the file before use. - Preinstalled User-Defined Commands (UDCs) provide access to the COBOL 74 compiler with the MPE-V/E :COBOLII, :COBOLIIPREP, and :COBOLIIGO commands, and to the COBOL 85 compiler with :COBOLIIX, :COBOLIIXPREP, and :COBOLIIXGO. However, note that the simulator currently does not provide the HP 32234A COBOL II firmware instructions, so programs generated by the COBOLII compiler will abort at run time with "ILLEGAL INSTRUCTION" errors, limiting the current utility of the compilers to syntax checking. Thanks once again go to Frank McConnell for providing the HP line printer subsystems manuals that facilitated development of the new simulation, and to Robert Mills for providing the COBOLII UDCs. -- Dave

Latest addition: A bondi-blue iMac

by terry＠webweavers.co.nz

My classic/vintage computer activity has taken a back seat lately but I did find a machine I had on the "classic" list for some time. It's now part of the collection. http://www.classic-computers.org.nz/collection/imac.htm Some would say this is not vintage, classic or collectible (and so shouldn't be discussed here). However, these are all subjected terms which can be (and are!) argued about at length. To me it's a noteworthy model which had some impact on personal computing (notably by helping put Apple back in the game). Vintage? At only 18 years old perhaps not but a classic and collectible? As time goes by I would say yes. Terry (Tez)

They got a good result first time. That seemed too easy. Then I remembered that when I went through the molding and casting process they said is that it? It just dawned on me. Screen printing is all about handling gloopy liquids. They have all of the knowledge of mixing and all of the measuring pots and stirring sticks you will ever need. Cost? Well that's interesting. Usually in a small run/custom situation its the labor cost that's the major element. Here it seems to be the cost of the materials to get the right result. I should know soon. Regards Rod

BASIC challenge on RetroBattlestations

by fozztexx＠fozztexx.com

July is BASIC Month and there's another challenge happening on RetroBattlestations. The type-in program for this challenge borrows a little bit of code from the very first BASIC challenge that I did. I've created a little "turtle graphics" type program that uses a stack based command interpreter. Right now the commands are very simple, pen up & down, move forward and turn. There's also looping to make it easy to create that spirograph effect that everyone loves to do! This time around there's more than just the random winners for typing in the program as-is. I'll also be choosing two people who can add the most interesting features or port it to the most exotic hardware. So far there are not too many platforms that have been ported to, and the only features that anyone has added has just been random colorization. You can check it out here: https://redd.it/4qs0f3 -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com

word processor history -- interesting article (Evan Koblentz)

by jnc＠mercury.lcs.mit.edu

> From: Mouse > "The most amazing achievement of the computer software industry is its > continuing cancellation of the steady and staggering gains made by the > computer hardware industry." - credited to Henry Petroski There's a reason I run considerably older software (which I prefer because it's less bloated) on somewhat older hardware (which is cheap, used) - i.e. hardware that's considerably newer than the software running on it - and your quotation nails it. The response time I get with Epsilon V8.0 (circa 1996) on an Athlon XP is scintillating - my finger has barely started to come up on the key before the screen reflects the command (e.g. to switch buffers). The response time is blindingly fast. Now, admittedly, Epsilon was fast to start with (i.e. on contemporanous hardware), so perhaps it's not the best example. But the same is true for other things, albeit to a lesser degree; e.g. switching windows to different applications. Older software on newer hardware provides a sparkling user experience, in terms of responsiveness. Noel

Repairing a Supermicro P6DLF motherboard

by tothwolf＠concentric.net

I'm currently in the process of repairing a Supermicro P6DLF motherboard which suffered shipping damage and I'm trying to find anyone else who might have one. I can't find any photos of one of these boards online (except for the one I recently purchased) and the board I have shows possible signs of prior rework that I'm trying figure out. The electrolytic capacitors on this particular board at locations CE1 and CE6 have Sanyo OS-CON 220uF 10V polymer parts (purple sleeve and appear to be 10SA220M) fitted and the solder work was done by hand. The joints were completely defluxed/cleaned, but the leads were hand sheared down into the solder joint. All of the other electrolytic capacitors on this board are Sanyo CG series 1000uF 16V (green) that were wave soldered. I suspect two of the Sanyo CG series parts were replaced at some point by a prior owner with the SA series polymer parts. According to the SA series datasheet, the largest 10mm diameter part is 220uF 10V, which may be why those were installed. I haven't used one of these boards since the late '90s when I built a workstation with one, and I can't remember with 100% certainty that Supermicro didn't use a few polymer parts on these boards. If anyone else has one of these boards and can physically check it to see what parts are installed, it would be really helpful. Many of the original Sanyo CG series parts were trashed on my board when it was shipped in one of those thin USPS Priority boxes, so I'm going to end up replacing all of them. If the two OS-CON parts turn out to be not original, I'll fit the correct value parts in those two locations while I'm at it.

"FIRST"??!? (Was: word processor history -- interesting article

by jnc＠mercury.lcs.mit.edu

> From: Fred Cisin > the first person to use a word processor was probably typing business > letters and/or legal documents, which is what they were developed for. Depends what you mean by "word processor". If you mean 'software intended to format text', you need to look back to things like TJ2: https://en.wikipedia.org/wiki/TJ-2 and 'runoff', both circa 1963. Much earlier than any of the 'word processors' this person wrote about. Noel

M7237 KJ11-A Stack Limit Register scans

by jnc＠mercury.lcs.mit.edu

There was some recent discussion of the need for M7237 (KJ11-A Stack Limit Register) boards, and I said I had one, and could scan it (for the PCB traces - they aren't in the FMPS) if someone wanted to duplicate it; I had a request for same, so scans are now online, here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/PDP-11_Stuff.html It will be a little bit of work to produce PCB artwork, since some of the traces dive under chips (and I'm not about to lift the chips :-), but from the prints (in the 11/40 print set, page 112) it should be easy to work them out.

> Googling "user server lift" didn't produce anything Oops, typo: "user" -> "used". (The prices I was seeing for these things was high, so I was wondering if used ones might be a bargain.) I also should have mentioned that I'm looking to put heavy assemblies (disk drives) up high in a 6' rack - say at the 5' level, counting the raised floor section the racks are one -q so the engine hoists aren't an option. (By an odd coincidence, I happen to have one of those Harbour Freight units in my garage, and it's a great engine hoist; not high enough for this, though.) And I was hoping for something in the $200 or so range, and even the cheaper manual units are more than that, new. Noel

harbor freight has some excellent platform lift things... worth checking.... we like things like this as large TV studio cameras weigh 100 to 200 <<and one here is 300 (tk42)>> when we get a caucus in and want to clean it up and make it presentable for display we like to work on it at bench height... (once in a while it is good to raise a tape drive up in the air too...) << I can't believe I used to grab a 7970E out of a rack... walk it across the computer room and put in another rack by my self......no more.... I just look at it in the rack and get tired now!!>>> ED# In a message dated 7/4/2016 4:12:07 P.M.

It has an extendable beam and a bottle jack to raise it. It folds up into a pretty small package when not in use. These can often be had pretty cheaply. Jon

Disc Imaging / Kryoflux - Acorn ADFS 800KB

by austinpass＠gmail.com

I'm trying to preserve my Acorn ADFS 3.5" discs. To this end, I've purchased a KryoFlux "Pro" board and a new-old-stock ALPS floppy drive. I've hooked it all up to a Windows 8.1 VM and everything *seems* to be working. However, the .adl images I create are all 0KB in size. I've created a profile to match the discs I'm reading (256byte sector size, tracks 0-79, MFM encoding, interleaved sides). Recording the flux transitions captures data, but when I run the resultant data back through DTC I get the same. Any ideas? -Austin. Sent from my iPad

Edinburgh folks heading for TNMoC, BP in Aug

by gtoal＠gtoal.com

Hi folks - if any of the folks I used to know are still on this list (Tony Duell? Pete Turnbull? Jim Doran? Jules Richardson?), I just wanted to let you know I'll be visiting TNMoC for the first time on 11th Aug. I mentioned this on the Edinburgh Computer History Project list and a few of the old Edinburgh hands will be coming along to make a day trip of it. If anyone is going to be in the neighbourhood and wants to say hello while we're there, let me know (or subscribe to our Yahoo group for updates) We had an Edinburgh connection with BP through Donald Michie, and I believe a bunch of our old computer center hardware (2976?) ended up in a shed at TNMoC. Best regards, Graham (PS I was never gone, I just don't post much.)

Early PDP-11/45 backplane SPC power

by fritzm＠fritzm.org

So, after finding that a DL11-E wasn't working in the backplane SPC slots (26-28) on my 11/45, I took a closer look. The problem isn't exactly what I had expected -- -15V seems to be distributed there, but +15 is not. Looking closely at the print sets, the listed configurations only mention DL11-A, the 20ma current loop model, which wouldn't require +15 to work. I wonder if some +15 distribution wires were added in an ECO, or maybe EIA console from the backplane SPC slots was never supported for these early 11/45s (mine is serial 152). There's one other oddity -- the power distribution table in EK-11045-MM-007, page 510, implies that +15 should be distributed to the SPC slots on CA1. I'm wondering if this is a typo, since I'd expect that pin to be NPG? The DL11-E looks to be expecting +15 on UA1 in any case.
