Dissolving a collection: bits for sale, including books

by joachim.thiemann＠gmail.com

Hello everyone, anticipating a move across the Atlantic in the near future, I decided to start selling a large part of my collection. I'm still adding things on occasion, but I would guess that mostly the books might be of interest to folks here. I've put the list(s) up here: http://sites.google.com/site/oldcomputerbitsforsale/home I would of course prefer is someone local can grab the stuff, but I am willing to mail things.

Machine code riddle

by cclist＠sydex.com

I'm working with an old data sample (ca. 1979) to a piece of equipment that I do not have access to. I've identified some bits and pieces of code and am trying to identify the processor. Here's what I know. The processor is big-endian and appears to be byte-addressable. The opcode for CALL appears to be D3 xx xx, where xxxx is the address of the destination. 2C appears to be load immediate instruction and is also 3 bytes long. The code doesn't look tight enough to be a p-code implementation of any sort. Does this ring any bells to anyone? --Chuck

TRS-80 Model I Power Brick

by alhartman＠yahoo.com

You can indeed open up the Model I bricks and repair them. A frequent failure mode is a fuse inside the case that blows out. My friend had one blow out, and he cracked it open, drilled a hole for a fuse holder and replaced the fuse. It's a pretty simple power supply to build a replacement for. There's a schematic on the Yahoo! TRS-80 group files section for an Australian 240v version which could be adapted to make a 110v version. The service manual is out there (Tandy and SAMS) which should have schematic as well.

OS/2

Apart from Lawrence, who AIUI is a former user - as he just gave me a pile of OS/2 boxes yesterday :?) - are there any other OS/2 users on the list? Or are there any active OS/2 mailing lists still around? I am wondering if I can get a copy of the subscription-only last couple of fixpacks for Warp 4 anywhere.

IBM Model M keyboard repair tip

by ard＠p850ug1.demon.co.uk

I think some of us like the INM type M keyboard... If you are brace enough to take the heatstaked 'sandwich' apart and replace the stkes with screws (I post the method for doign that some years back), it's easy for one or two of the 'flaps' to jump out of position when you're putting the bits together again. You then have a couple of keys that don't work and you have to take the whole thing apart again. What I do now is insert a flap then slightly stretch its spring and press it over the rear of the key plunger housing, forcing the rim of the housing between the coils of the spring. It'll stay like that, and the flap will be held in place. Fit all of them, put the rubber sheet, the membrane sheets and the base plate on, and screw it all together. Then unhook the springs by running a screwdriver along, and fit the keycaps. The plastic keyframe can be cafully cut between rows of keys (it sometimes breaks along these lines anyway). You can then use parts of 2 damaged keyframes to make one good keyboard. I am not sure what the offical sixe of head for the casing screws is. It's often quoted as 7/32", which turns out to be a smidgen more than 5.5mm. I've found both my 7/32" and 5.5mm nutdriver fit fine. Somebody was looking for some tpye M casing screws. Did you find them? I spent the afternoon making a good tpye M from bits of 2 broken ones, and thus I have soem bits over :-). I never thown anything away so I've got a box of flaps, screws, etc. I could probably be persuaded to part wit hthe casing screws... -tony

Kaypro 4 CP/M disks

by elazzerini＠interfree.it

Hi, I'm not unfamiliar with the various versions of the firmware of your Kaypro 4, but the only person that comes to mind is Dave Dunfield. In time he has collected images of boot disks of many machines. I arrange from a few months of a PC configured to be able to read and write disk images 3.5 " and 5.25", but I live in Italy. Once you've got practice on how to use the software to create boot disks is more 'easy to do that to tell it. If there is no one else to may help you I can try. I'll give you references of Dave Dunfield: At the bottom of this page http://www.classiccmp.org/dunfield/kaypro/index.htm for manual. Here for images of boot disks: http://www.classiccmp.org/dunfield/img63549/system.htm Here his contacts: http://www.classiccmp.org/dunfield/contact.htm Greetings Enrico - Pisa (ITALY)

ETH Lilith's on Ebay sold...

by jdr_use＠bluewin.ch

Whoever got that set of Lilith;s that where on ebay.de, if you are on this list that is, please ensure that you write-protect the disks. Medos, the Lilith OS, expects a writable disk, but will boot and run from a write-protected one. Otherwise you run the risk that a slight error in diskdrive or controller will ruin your disk pack. Happened to me more than just once... And don't forget to replace those Keytronic foam pads : Medos expects a keystroke before booting up ! And google for "Emulith" in case you want to try out my Lilith emulator first. Jos Dreesen

[REWARD] Request for documentation

by l4b.bogdan.barbu＠gmail.com

Hi, For quite a while now, I've been trying to get my hands on an old piece of IBM documentation for my collection before it is lost forever. So long, in fact, that I'm offering a reward of 500 USD to anyone that can find it for me. I've tried using my Google ninja skills, I've tried with IBM, I've tried libraries, and I've tried contacting a couple of patent authors that have used this as reference material. Perhaps you can do a better job than me. IBM Personal System/2 Mouse Technical Reference (S68X-2229-00, 2nd ed., Jun. 1989, IBM Corporation) If you are only able to find it at a library, see if you can borrow and scan it for me; that works just as well for me. Know that I already have the first edition of this document so I am not interested in it. Good luck! Cheers, Bogdan

Release 2 represents not merely a software update, but acomplete re-authoring of GNOSIS from beginning to end. GNOSIS provides a CAI authoring language which makes itrelatively easy for any teacher with a basic understanding of ?pro-grammed? textbooks to develop computerized tutorials for his students.Although material already written in such a format can be transformedvirtually as~is by GNOSIS into a form suitable for computer delivery, theteacher would normally be writing his own ?script?. This script. because itsimulates the dialogue one might overhear if that teacher were tutoring astudent in private, can be made to ?come to life" on a computer terminalby the addition of a few simple GNOSIS command words. Thecomputer-driven tutorial is, in reality. a compiled version of the ALGOLprogram GNOSIS writes in response to the script prepared by the teacher.In fact. GNOSIS can be designed in such a way that any of the facilities ofALGOL can be exploited anywhere in the lesson. The fact that GNOSIS has been designed to function as a reachingrather than as a testing system is reflected in program logic at all levels. Inaccord with this design philosophy. GNOSIS tempers negative andpositive feedback according to physchological context, simulates a correctresponse (and the comment which would have accompanied it) when allelse fails, encourages student control through skipping and backsteppingfacilities. and generates teacher reports which are geared to lessonimprovement.

Apple2gs emulation

by dgriffi＠cs.csubak.edu

Does anyone know anyone associated with the xkegs Apple2gs emulator project? The latest version seems nice, but supports only OSS audio, which is a little bit of a pain to deal with on modern Linux systems. There is an SDL fork out there, but it hasn't been updated in nine years. I'd like to figure out how/if the latest xkegs can be patched to do SDL or if there's another Apple2gs emulator worth playing with. Last time I tried MESS for this, I got hopelessly lost. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

John Romero to keynote KansasFest 2012

by pr＠kansasfest.org

SEPTEMBER 30, 2011 -- KansasFest 2012, the Apple II convention scheduled for July 17?22 in Kansas City, Missouri, comes just two months after the twentieth anniversary of Wolfenstein 3D, the first-person shooter that, when released for MS-DOS in 1992, defined a genre that is still popular today. Not only did the game, which was later ported to the Apple IIGS, use as its inspiration the Apple II game Castle Wolfenstein; Wolfenstein 3D's creators got their start working at Apple II disk magazine Softdisk. To commemorate that anniversary and heritage, KansasFest 2012's keynote speech will be delivered by none other than Wolfenstein 3D co-creator John Romero. Romero, whose Apple II credits include Dangerous Dave and Dark Castle, has been a pillar of the electronic entertainment industry for nearly as long as the Apple II has existed. Popular Apple II magazine inCider published Romero's first program in 1984, with many more of his titles to appear in both inCider and Nibble. Romero later joined Origin Systems, publisher of the Ultima and Wing Commander games, as a programmer, after which he co-founded Inside Out Software. At both companies, he ported software to and from the Apple II and Commodore 64. With KansasFest 2008 keynote speaker Lane Roathe, Romero also co-founded software company Ideas From the Deep, where he developed the Apple II game Zappa Roidz as well as the InfoDOS operating system for Infocom's Apple II games. In 1989, Romero joined Softdisk, a stint that introduced him to three important people: John Carmack, Tom Hall, and Adrian Carmack. The four co-workers left Softdisk in 1991 to co-found id Software, which a year later revolutionized electronic gaming and demonstrated the potential of the shareware distribution model when they released Wolfenstein 3D, which sold 100,000 units in its first 18 months. Later id Software blockbusters, including DOOM and Quake, further cemented the company as an industry powerhouse. Romero has since been involved with many additional high-profile games, including Deus Ex, Daikatana, and Gauntlet: Seven Sorrows. He most recently co-founded social games company Loot Drop, developer of the popular Facebook game Ravenwood Fair, which currently has nearly five million users. Despite such overwhelming success and a storied r?sum?, Romero has long celebrated his roots as an Apple II programmer. In 1998, he reunited forty Apple II programmersin celebration of the Apple II turning 20 the year before. So prestigious were Romero's invitations that in attendance was Apple II inventor Steve Wozniak, KansasFest 2003's keynote speaker. It was this event that later inspired Jason Scott, keynote speaker at KansasFest 2009, to begin production on a documentary of the 6502 processor, which powers the Apple II. Romero appeared in Scott's text-adventure documentary, Get Lamp, and will support Scott's upcoming 6502 film as well. >From Commander Keen to DOOM and Quake, Romero's games ? 97 to date ? regularly become household names and spawn countless imitators. Romero's reflection on the role of the Apple II in both his and the industry's successes will captivate KansasFest 2012 attendees. KansasFest is an annual convention offering Apple II users and retrocomputing enthusiasts the opportunity to engage in beginner and technical sessions, programming contests, exhibition halls, and camaraderie. KansasFest was originally hosted by Resource Central and has been brought to you by the KFest Committee since 1995. Any and all Apple II users, fans, and friends are invited to attend this year's event. Registration details will be announced on the KansasFest Web site in early 2012.

Migration from VAX 3100 to SIMH questions and looking for ideas

by trash3＠splab.cas.neu.edu

Hi, Our 3100 is dying. Thinking of running SIMH. Big stumbling block is how to move the OS and files. I've used Kermit when I've done this for RT11, but that seems like torture for 8 Gb on two disks. Can't I just stick in a SCSI controller and use something like ODS2 to read the SCSI drive and put them into the new container? Thinking of using (probably) XP or Windows7. Am I missing something here? And, if I read it correctly, the only device that talks to the outside world is the ethernet connection in SIMH-vax. Well, that will take care of pretty much everything, I guesss, since we only have printers and terminals, and I can switch over to PCs with VT100 software. Anybody been through this already and have some pointers? thanks in advance Joe Heck

Copying in a real TU-58 one virtual TU-58 tape

by will_kranz＠softhome.net

I did a fair amount of research and coding for TU58 emulation over the years, most of that experience and links to utilities for MSDOS and Linux are available at http://www.willsworks.net/pdp11/tu58-emu.htm

I built one years ago, initially for the CoCo, I later used in on an MS-DOS machine. It consists of 16 output lines (notionally address, but could be used for enables/clocks where nexcessoar), 8 input lines (used to read in the data), and +/-5V, +/-12V power lines. The CoCO version used TTL latches and buffers, the PC version used an 8255 PCB from Maplin. A manual toggle swithc tri-states all ouytput lines and turns off the PSU rails so you can safely insert/remove ICs. These signals all go to one row of pins of a 64 pin DIN 41612 socket. The other row of pins is wired ot the 32 pins of a ZIF socket. I then have little boards with a DIN41612 plug wired appropriately to conenct the inputs, outputs, and power lines ot the right pins of the socket. I suspect that for me, soldeirng up wone of those boards takes less time than modifying a configuration file, so it's actually easier for me to do it in hardware than to have thing that's configured in software. -tony ------------------------------ Message: 4 Date: Thu, 29 Sep 2011 16:46:20 -0400 From: Dave McGuire <mcguire at neurotica.com> To: General Discussion: On-Topic and Off-Topic Posts <cctalk at classiccmp.org> Subject: Re: Kanbak-uino Arduino-based KENBAK-1 Recreation Message-ID: <4E84D91C.5080800 at neurotica.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 09/29/2011 04:17 PM, Ethan Dicks wrote: > On Thu, Sep 29, 2011 at 4:09 PM, Dave McGuire<mcguire at neurotica.com> wrote: >> I just landed a big consulting job (one of the reasons I'm in the process >> of moving from FL to PA, there's actual WORK here!) > > Hope to see you at the Pittsburgh Mini Maker Faire next month. Hey, you'll be there?! Yes, I'm thinking Dan Roganti (from whom I now live right up the road) and I, as well as my fiancee' Autumn, will almost definitely be in attendance. We'll have to catch up on that privately before the event so we can find each other. And since you'll be in town, you're welcome to come up to see my new place. It's very much a work in progress, but I have a 4700-square-foot room here filled to the gills with awesome hardware. Most of my old iron is here now, though not quite all. My new place is in New Kensington, about 18mi NE of Pittsburgh proper, right up Route 28. >> that will have me doing a lot of AVR work. I'm looking forward to that. > > Cool.

If you program in assembly, you'll learn to hate the AVR assembler. (Yeah, I know there's one in GCC as well, but it's not the same thing, as a *real* macro assembler). Must have been an assignment for an intern. There are better alternatives, if you're willing to work a bit to keep things updated to the chip you're working on. --Chuck ------------------------------ Message: 9 Date: Thu, 29 Sep 2011 17:01:49 -0400 From: Dave McGuire <mcguire at neurotica.com> To: General Discussion: On-Topic and Off-Topic Posts <cctalk at classiccmp.org> Subject: Re: Copying in a real TU-58 one virtual TU-58 tape Message-ID: <4E84DCBD.7040005 at neurotica.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 09/29/2011 04:35 PM, Alexandre Souza - Listas wrote: >> I believe there's an optical shaft encoder on the spindle motor of the >> TU58.

A DC600 QIC02 style tape uses holes punched into the tape and an optical sensor to determine BOT/EOT. The TU58 is actually closer to a 3M Iotamat drive. Given the cantankerousness of the medium, however, TU58 emulators have been developed. --Chuck ------------------------------ Message: 12 Date: Thu, 29 Sep 2011 17:24:33 -0400 From: Dave McGuire <mcguire at neurotica.com> To: General Discussion: On-Topic and Off-Topic Posts <cctalk at classiccmp.org> Subject: Re: Migration from VAX 3100 to SIMH questions and looking for ideas Message-ID: <4E84E211.6000902 at neurotica.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 09/29/2011 05:00 PM, Gene Buckle wrote: > On Thu, 29 Sep 2011, Dave McGuire wrote: > >> >> Ok, did anyone else spot the little typo just before Brian's mailer's >> reply quote? ;) *snicker* >> >> -Dave >> >> On 09/29/2011 02:06 PM, Brian Wheeler wrote: >>> b duaOn Thu, 2011-09-29 at 17:47 +0100, Rob Jarratt wrote: >>>>> -----Original Message----- >>>>> From: cctalk-bounces at classiccmp.org [mailto:cctalk- > > So many windows, so little time. :) (hears Dave yell "FOCUS!" in the > background) ROFL!! -- Dave McGuire Port Charlotte, FL ------------------------------ Message: 13 Date: Thu, 29 Sep 2011 14:28:08 -0700 From: steve shumaker <shumaker at att.net> To: cctalk at classiccmp.org Subject: Re: Free for the cost of shiping : Altos CPM and MiocroSoft COBOL 8"disc's Message-ID: <4E84E2E8.9040505 at att.net> Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 9/29/2011 1:24 PM, Rik Bos wrote: > Spoken for.. > > >> -----Oorspronkelijk bericht----- >> Van: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org] >> Namens Rik Bos >> Verzonden: donderdag 29 september 2011 22:00 >> Aan: General Discussion: On-Topic and Off-Topic Posts >> Onderwerp: Free for the cost of shiping : Altos CPM and MiocroSoft COBOL >> 8"disc's >> >> Free for the cost of shipping : Altos CPM and Microsoft COBOL 8"disc's >> >> About 10 discs I don't have the hardware anymore, so before I format the >> discs... >> >> >> >> -Rik >> > > oh bummer. would the proud new owner be willing to make copies of the cpm disks..... please.... steve ------------------------------ Message: 14 Date: Thu, 29 Sep 2011 14:29:08 -0700 From: "Chuck Guzis" <cclist at sydex.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: Firmware library was Kaypro 4 CP/M disks Message-ID: <4E8480B4.30161.18FFE9E at cclist.sydex.com> Content-Type: text/plain; charset=US-ASCII On 29 Sep 2011 at 21:31, Tony Duell wrote: > > A worthwhile project might be a cheap "universal PROM/PAL" reader. > > I built one years ago, initially for the CoCo, I later used in on an > MS-DOS machine. > > It consists of 16 output lines (notionally address, but could be used > for enables/clocks where nexcessoar), 8 input lines (used to read in > the data), and +/-5V, +/-12V power lines.

That expands it to 16 outputs, and 20 inputs (from the DUT's perspective) (the low order 4 bits of the first 393 drives the select on the 151s). I've got headers on all of the outputs and inputs as well as on the DUT socket, so it's just a matter of jumpering things how you'd like. With a wirewrap gun, it's literally just a couple of minutes to change the configuration. But a uC has a huge advantage when creating a general solution, as you don't need any sort of pin drivers--just change the programming for the uC pins and you're all set. I was lazy with mine--I knew that counters would work and required no device programming, leaving the smarts on the PC side. --Chuck ------------------------------ Message: 15 Date: Thu, 29 Sep 2011 14:32:20 -0700 From: "Chuck Guzis" <cclist at sydex.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: Machine code riddle (Fairchild Series 70 system) Message-ID: <4E848174.19280.192ECFC at cclist.sydex.com> Content-Type: text/plain; charset=US-ASCII On 29 Sep 2011 at 21:25, Tony Duell wrote: > Is it?

Yes, I've looked into Charon and the cost would probably bankrupt the company. At least that's how I read their price list. Yes, it's the right way to go, but... I suppose the company could take the COBOL code and move it to a real PC environment as well...get away from VMS entirely. Since at least one person suggested staying with the real hardware, perhaps that is the best bet. I'm not even happy about upgrading the OS, since I really don't want to get the license manager into a fit. The hardware seems pretty stable, except for the disks. I had asked about disks a while back and got many excellent responses. However, I went with one which was to buy the new "cheetah"? drive, very big, and unfortunately, 5.5-2 won't support it, along with the firmware. My bad, I forget to say the system is running antiquated software. So, it's back to the 4GB drives. Went with a used drive from a reputable vender, and things are stable for now. You've given me many good options to think about, so now I have to make a recommendation to my friend/client. Just when I was about to retire and get out of the business...

Ya... good idea except, I can measure nice clean tach pulses on the board after the op-amp stage that the photo transistor in the interrupter drives. So, I think I'm getting good tach signal from the interrupter.

Apple 2gs goodies

Has anyone here bought Apple 2gs stuff from 16sector.com? Playing with an emulator got me thinking about pulling out the actual hardware and hopping it up to what I craved the first time round. They have an 8M memory expander and an IDE interface, among other things.

Ontel 8" floppy disc drives cabinet

by spedraja＠ono.com

Hi. Just received one ONTEL (not Intel) 8" floppy disc drives cabinet from the UK. * Reasonable good external aspect. * The drives appear to be Shugart. * The power supply has good aspect in a first visual inspection. * The fuse in the cabinet rear and the fuse cover are lost. I must check for one valid cover. The most interesting thing is the output interface. Every disc unit plugs in a circuit in the cabinet rear. The circuit have the holes needed to put the usual 50-pin interface. BUT the interface really installed is one similar to parallel or DB25. Sure that I can try to install the 50-pin interface. And I shall do more investigations, but any help in all these aspects would be welcome. Regards Sergio

Ontel 8" floppy disc drives cabinet

by tshoppa＠wmata.com

Probably from an Ontel OP-1 system in the late 70's or very early 80's. The OP-1 was somewhere between a configurable terminal and a dedicated word processor depending on firmware and peripherals installed. Peripherals did include 8" floppies in the high end, I saw this being used in car dealerships back in the early 80's as the front end to a central-office PDP-11 system. There are at least a few other manufacturers that used 8" floppies on a DB25 cable. E.g. the RX01 cabinet kit for a WPS-8 system. I would not expect to find any of them using compatible pinouts or even "interface concepts". E.g. the RX01 is a dedicated serial bus with some smarts (or at least a state machine) at the drives. The DSD-440 line used a different dedicated serial bus (26 pin ribbon cable IDC's usually but I think I saw it routed over a DB-25 at least once) and a microprocessor in the drive. I'm guessing your board that sits between 50-pin Shugart and 25-pin connectors, doesn't have much smarts, it probably just drops the many unused signal lines and consolidates many of the grounds.

8" floppies

by jws＠jwsss.com

I just got a box of 8" media which included some boxes with Fairchild Camera logos I usually see on high speed camera equipment I collect. There is something called a Fairchild Series 70 with what appear to be floppies labeled for such a system in one box. There were probably more, but they are full of Tarbell media, which I need as well. Any idea what this is? I will try to rig something or find someone with the means to digitize it and donate it to Bitsavers, of course. I'm in the LA area (California) if there is anyone around. I have a DiscFerret from Phil P. if someone has a clean working 8" setup and some time to get it all running. I have 8" drives, but they are in unknown working condition. For what it's worth, it looks like the person with the Tarbell media had the same problems I had and most other did as there are a number of floppies labeled as to where they were written, since Tarbell controller were notorious about reading a lot of media, but writing media only Tarbell could read. I also have a box with a Dysan reference floppy as well if needed in the same lot. Thanks Jim

Copying in a real TU-58 one virtual TU-58 tape

by spedraja＠ono.com

Hi. I have one TU-58. Doing a resume: * The components work at 115 volts, even when you can change the PS current to 220-240 volts. * In appeareance the Current flows by the main board of the device (the RED led indicates so) * The wire wrapping is the stablished in factory (TU-58 manuals, Bitsavers) * It has not stablished the 'boot' wire wrap for LSI-11 * I have one DEC console serial cable * I have too a couple of Dectape II cartridges With all these stuff, I should like to connect the TU-58 to the Serial Port of my Laptop and manage the TU-58. The objective is: * To put a virtual image in the Dectape II from the Laptop * To dump the content of one Dectape II in the Laptop The unique option similar to this that I want is one MS-DOS driver in SpareTime Gizmos, but to use the TU58 as one MS-DOS storage unit. But, what I have in mind is similar but different at the same time. I want to manage the TU-58 contents in DEC native format. I know, in addition, of the existence of some TU-58 emulators, and in fact I use them from time to time. And I'm not sure if one of these (TU58EM) has this option available, but sure that someone in the list knows it. I suppose then that some analysis of the STGiz MS-DOS driver plus the diverse emulators of the TU-58 would be sufficient to begin to construct some kind of software for this purpose. But it's almost sure that someone has encountered this problem in the past years and encountered one solution for it. Probably even with only one communications software, a good knowledge of the RSP protocol, an one binary image. In the other hand, I am almost sure too that I need a modification (or better a modified plug) of the Serial Port in the Laptop (9-pin) as the realized in the SLUs of the PDP-11 to allow the correct manage of the TU-58 >from the laptop. I have the documentation of modifications to do in the SLUs of the PDP-11, and in fact I did a couple of modified SLUs some time ago. In the cas of the laptop it would be neccesary to one male-to-female plug. The problem is the correct cabling inside it. I assume that I can do the well-known probe-an-error but sure that exists some contrasted information about the cable. Thanks ! SPc.

Mac IIci's: save or scrap

If not the whole system, there are a couple of 'special' boards in them: - Pro Tools Audiocard - Sound Accelerator II - Radius Accelerated 24-bit Graphics They are located in the Vancouver area, B.C., Canada. I could extract and ship boards, I don't expect they are worth shipping whole units. .. just thought I'd ask/offer, eWaste otherwise.

update and pics of 11/785 and opps... slot machine

by useddec＠gmail.com

The person who owns the 785 finally got it dug out, and I looked at it about a week ago and got a few pics. Unfortunetly, he pulled the main boards and sold them for scrap. I have a spare 780 board set and backplane, and most of the 785 board set. The pics show better detail than I could see because of poor lighting. I couldn't find the flashlight I keep in the car. The expansion cab has the BA11-KE and boards are in it. The 11/03 and RX02 are there. I will be happy to dig into it in more detail if anyone is interested. No tape or disk were seen while there, but he doesn't remember getting rid of them. It might end up getting totally parted out. I just opened a flickr acct, and accidently left on pics of a slot machine. An aquantance passed away and I'm trying to help his daughter to find a home for it. Any gamers? All located in Chanpaign, IL area. Thanks, Paul http://www.flickr.com/photos/useddec/

Kaypro 4 CP/M disks

by percy.walls＠gmail.com

I was given a Kaypro 4 that had belonged to my father-in-law. he died about 6 years ago, and the machine was stored in a unventilated garage in NM, and any disks where either lost or are unusable. I am a retired disabled vet, and only have a newer laptop and with no 5 1/4 drive to be able to recreate the disks from the archives. I would be very great-full if someone could supply me with a set of CP/M OS disks, a basic interpreter and compiler, and maybe some games. I'm more than willing to pay a modest amount for materials and time. Also can anyone know where I can purchase floppy disks for the Kaypro Thanks in advance Percy Walls ETC USN Ret.

C&K Digitast. There are knock-offs by others that look similar and are cheaper... but don't feel the same. http://www.ck-components.com/digitast/key-switch,10465,en.html Most of the C&K switches from the 70's are available almost verbatim (modulo ROHS and whatever) today.

Finding one IBM 2741

by spedraja＠ono.com

I'm doing a review of all the IBM stuff which I took from the Datacenter in the last cleaning. Having one 3279 in working state and one 3278 almost (the logic board needs replacement), plus one 3178 still alive and one 3174 ready to work with Hercules, I should like to get one 2741. As difficult as the lottery, I suppose, but for try it... Regards SPc.

SC Spreadsheet

by david＠thecoolbears.org

Does anyone know where source code is for the SC curses based spreadsheet - specifically, a version that will compile on OpenVMS on VAX? I have sc-7.16, but I'm not having much luck getting it to compile (it compiles OK on Linux). I saw some indications that pre-7.x versions will still compile on VMS, but 7.x and later will not. Executables would be OK, but obviously not as good as source.

NTSC video output from Sinclair ZX81?

by charlesmorris800＠centurytel.net

I'm dusting off my ZX81 with 16k memory pack (the pair cost me $200 in 1981!) and have already discovered that the Z80A chip has definitely gone bad. (The HALT\ output pin sits at an indeterminate-level 1.2 volts even with the logic IC removed, and the CPU is halted). I had a Z80L (good for only 1 MHz and the clock is 3.5 MHz) in the junk box, but even so, swapping it resulted in lots of activity on the address, data, read and write lines, etc. as well as video pulses coming out of the custom logic chip, pin 16. http://www.mainbyte.com/ts1000/good_schematic_hi.jpg I'd like to take the output from that pin, which currently goes to a "canned" RF modulator through a couple of resistors and a diode, and instead convert it to NTSC video, as I also have a 9" monochrome CCTV monitor (75 ohm input) which would make a compact display. Can someone help me with a simple circuit to generate the appropriate RS-170 1 volt p-p video signal? thanks Charles

TMA-11 Read

by iamvirtual＠gmail.com

Hi, I am trying to archive my tapes. I am having difficulty reading the tapes. I tried 2 tapes that are of low importance. I am able to read the first 2 records (the first record is 14 bytes and the second record is 512 bytes). I see the tape move for the read as well as the backspace operations. I setup a simulated environment to test prior to using real hardware. Using a slightly modified version of SIMH along with PDP11GUI and a virtual tape, I successfully read virtual tapes. Now that everything is working on a simulator, I am using the same code on real hardware. The real hardware is a PDP-11/10 with 32kw core memory, TMA-11 controller with TS03 tape drive. I also have a RK-11 controller with an attached RK05j drive which is available, but is not used during this scenario. I don't know the actual format of the tape. My goal is to get a binary copy of the tape suitable for use with SIMH. Now that I am using real hardware, I am getting a Record Length Error. I set the read buffer to 2048 bytes (1024 words). The values I have from the TMA-11 registers is as follows: MTS 001105 MTC 160202 MTBRC 000000 MTCMA 000000 MTD 000000 MTRD 000000 I am looking for some source code to figure out what is going wrong. I have reviewed the simple example in the TMA-11 documentation, but proper error handling is not performed. Thanks! ; +=============================================================== ; | read ; +=============================================================== ; | ; | Read record from tape.

RTE IV-B HP 7920 Grandfather and Primary system disc (NOS)

by hp-fix＠xs4all.nl

I've two HP 7920 RTE IV-B cartridges one Grandfather and a primary system disc for the HP 21MX both seemed to be unused and have been in storage forever..(and should be cleaned for use !) I don't have a HP 7920 drive I do have a HP 7906 in unknown condition and a HP 2113B which I love to see running RTE. So I'm looking for someone willing to : sell or trade me a HP 7920 drive, or someone transfer the data from the packs to tape or disc or any other solution which provides me with the RTE-IV software for the HP 2113. If can't get a HP 7920 then the packs are for trade. I'm living in the Netherlands so picking up a 7920 in Europe is possible, shipping the packs to the US also but only . Please react off-list -Rik

NorthStar stuff for sale

by lynchaj＠yahoo.com

Hi, I have one complete Northstar Dimension and another only missing some parts of the power supply. Northstar Dimension computers are quite rare machines from the era of transition from S-100 to the IBM PC clones. There are also a couple of Northstar Advantages in the original boxes. The Dimensions are also in the original boxes. There are some spare parts for the Dimensions and Advantages including some software and maybe some documentation. One more item is a NorthStar 15MB external hard drive. This is quite a large and rare unit. At least this is the only one I've ever seen or heard of. I am not 100% sure but it looks like it may be a 14" hard drive platter. Seriously, this thing is as big as a full sized S-100 chassis by itself. Due to the nature of these items, they are for local pick up only. I am not interesting in shipping these items. There is also some NorthStar software in original boxes, packing, etc TSS/A HD Horizon Order Entry and Invoicing HD Advantage (2) Inventory Control and Analysis HD Advantage Graphics BASIC DOS PIO Advantage Info Manager II HD Advantage TBS/OS Advantage Enhanced WordStar Advantage CP/M (5) Enhanced WordStar Horizon dBase II Advantage CP/M (3) dBase II Horizon 8/16 Upgrade Advantage Accounts Receivable HD Horizon NorthPlan FD Advantage NorthWord II FD Advantage TurboDOS 1.1.1 Horizon NorthNet Advantage (with board) CP/M 2.2 Rev L1.0 Horizon General Ledger HD version Advantage Accounts Payable HD version Advantage Image Maker Advantage CP/M TurboDOS I am willing to sell but due to size these need to be picked up (Ohio) in person. Please contact me for more details. Thanks! Andrew Lynch

push buttons w/ LED

by chrise＠pobox.com

In Adrian's photo of the Intel MDS225 here, http://img9.imageshack.us/img9/6826/intel2.jpg you can see a row of eight push buttons with LEDs in them just below the CRT. They are a really nice push button that I have a certain affinity for. Does anyone know who made/makes those or have a modern source for them? Chris -- Chris Elmquist

Lots of Amiga stuff available

by dbetz＠xlisper.com

I recently acquired a bunch of Amiga equipment that I'm not sure I'm ever going to get a chance to use. I'm currently looking for someone who might want this equipment. I got it for free so I will pass it on at no charge as well. Just briefly, the main items are: 1) Two Amiga 500 computers 2) A sidecar style hard drive for one Amiga 500 3) an Amiga CD32 game machine 4) a Paravision SX-1 attachment for the CD32 with lots of additional ports to allow the CD32 to be used as a computer 5) two 1084s monitors 6) numerous floppy drives including a number of 3.5" drive and one 5.25" drive 7) software and manuals for most if not all of the hardware I've seen one Amiga 500 boot from the hard drive into Workbench. I've also seen the CD32+Paravision unit boot into Workbench from a floppy. I don't know the state of the second Amiga 500 but it appears to be in good condition. I'm in southern NH and would like someone to take all of this equipment. Thanks, David Betz

Microcolour terminal

by ard＠p850ug1.demon.co.uk

Has anyone ever come across a 'Microcolour' terminal? It was made in the UK by Microvitec, who were better known for monitors (often BBC micros were used iwth Microvitec Cub monitors). I have a couple of the Microcolour base units here, no monitors or keyboards. Here's what I've discovered so far... On the rear are connectors for 'Host' (DB25 plug), 'Printer 1' (DB25 socket), 'Printer 2' (DB25 socket), Monitor (DB25 plug), Keyboard (DE9 socket), mains in/out (mormal IEC connectors, a couple of fuses and the on/off switch. The only feature on the front is a green power-on LED. Insdie is a PSU (the 2 units I have differ in the PSU design, but that's not vert important at the momnet0 nd a crdcage containg 3 PCBs (with aslot for a 4th). These plug into a backplane at the front fo the machine using 64 pin A+B DIN41612 connectors. The loweremost PCB carries the Host, Printer 1 and Keyboard connectors. On this board are the processor (6809), EPROMs, RAM (some of which is battery-backed -- I have removed the leaking NiCdsm there is no other damage), 4 6551 serial chips (for the printer 1 port, which is RS232 DTE, even though it's on a socket :-(), the keyboard port (TTL level), and the host port (it uses 2 6551s for this so yuo can have split baud rates I guess), a 6821 (used at least for the Printer 2 port which is thus a parallel interface, a cable rund from a SIL header on the PCB to the DB25 socket o nthe chassis), etc. One of the EPROMs has a label 'Regis' which seems to suggest what protocol it may use. The other 2 boards are video-relates. One seems to be text video (6845, several 6116 RAMs in a row on one edge, another couple of 6116s which may well be programmable character generator, there's no EPROM on this board), and lots of TTL. There's a 10 pin header which is linked ot part of the monitor connector. The last PCB seems to be graphics related. It contains 128K of DRAM, some 74S189 SRAMs for a oolour palette and again lots of TTL. There's a 15 pin header that links to the montior conecetor. Now for the monitor connector. It's a DB25 plug. One pin is not fitted, one is wired to chassis ground. 9 of the remainder go to the text PCB (one pin on the header is not used), the remaining 14 go to the graphics board (again one pin on the header is not used). Now fo the odd thing. All those signals are TTL level. The output of the graphics board (12 pins on the header) are the outputs of those palette RAMs. In other words 12 bits digital (I asusme 4 bits each for R,G,B). The otuput fo the text board is similarly a 4 bit value (I think). And of course there are 2 sync signals, which I could identify. Vsync is 50Hz (not too suprising), HSync is 21.8kHz. In other words, EGA rates .Sothis thing used a specail EGA-like monitor with many more input bits. I suspect I am goign to start by hooking up a normal EGA monitor (assuming I can find one, I think I have a 5154 around here) to see if I can get some output, albiet with fewer colours than I should have and then try modifying such a montiro t oincrease the numebr of bits on the DACs. As for the keyhoard, at least it's synchronous serial (of the pins on the DE9, there's TTL level TxD and RxD, ground, +5V, +12V, -12V). I have no idea of the baud rate, etc, but if necesary I cna use a logic analyser to see how it initialises the appropriate 6551. -tony

Floodgap back up

by spectre＠floodgap.com

As shocked to see that I haven't been bounced off the list by now, Floodgap and all of its hosted projects are back in full operation on a new T1 from AT&T/DSL Extreme. Do not ever do business with Time Warner Cable Business Class. They took six weeks to do nothing, culminating in fairly nasty threats to their legal office to get them to release me from the contract. AT&T took almost four weeks, but at least they got the NIU in, and the router got activated today. Reverse DNS is pending. Sorry about the downtime. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- ** COMMODORE 64 BASIC V2 ** 64K RAM SYSTEM 38911 BASIC BYTES FREE ----------

RK05

by cc＠informatik.uni-stuttgart.de

Hi, I'm trying to repair my RK05 drive. It seems that it doesn't find track 0 when loading the heads, thus moving the heads to the inner limit, forcing a return-to-zero and starting all over again. I think the fault is on the M7681 card (cylinder address and difference), the output of E16 pin 8 (CAD3 zero detect H) doesn't change, nor does the input on pin 10. And here comes the problem: the M7681 isn't described in any DEC documentation I've found so far (apart from the schematics), only the older M7702 card (the function is practically the same, but they are completely different designs). The new card contains several undocumented TTL ROMs (8223). The output of pin 6 of E1 goes to the input pin 10 of E16, probably a difference==zero bit. So here comes my question: does anyone have a ROM listing of these ROMs, especially of E1? I'd like to know what exactly that ROM is doing. Christian

intel mds 225

by jzg22＠drexel.edu

... I've never seen one of those mds computers before, but as soon as I saw it I realized that it is what the Speech Plus/Telesensory Prose 2000 Speech Synth card which I have was originally meant for/designed for. The card I have is in a special speech plus 'prose 2020' metal case with its own power supply, and the two 'multibus'? edge connectors of the card are unused, power and serial and audio come from/go to special secondary connectors on the board. But clearly, without the special prose 2020 case, the prose 2000 card would be used in one of those computers with 'multibus'. Any chance you can dump the roms from the computer? Given that there don't appear to be any multibus cards installed, are there even any roms to dump?

DEC GIGI - Power Supply Replacement Success

by mark＠wickensonline.co.uk

Folks, Always nice when you've got a piece of good news ;) I replaced all the mains filtering capacitors in the original DEC GIGI power supply when one blew only to find that the power supply lasted another 10 minutes before losing power completely. At this point I decided given the relatively standard power outputs (5V 3A, 12V 1A, -12V 0.3A) I would source a replacement power supply. This arrived and was installed yesterday. It I guess unsurprisingly is substantially smaller and lighter than the original. The original cooling fan was removed as it was basically transformed directly from either the mains directly or one of the windings of the main transformer. I used the fan out of an external SCSI enclosure as a replacement, although I look to source a high quality brand new one. To me it looks like the fan primarily is for cooling the PSU only - given the fan location and the location of the plate that the PSU is mounted on it looks unlikely that the main circuit board would benefit much. The machine now happily powers on and I had an hours playtime last night with the local BASIC monitor. The GIGI now only exhibits one minor trait, and I'm yet to determine whether this is down to the LCD panel it is driving being at limits or whether there is a slight issue with the video generation circuit. Once in a while, every couple of minutes or so the LCD looses sync and the picture is dropped. This only happens for a fraction of a second, then the picture is restored as was. If anyone has any ideas I'm all ears. For reference I'm using a Iiyama AS4637UT, an old but extremely capable 18.1" 1280x1024 native panel. If anyone is interested I can post the horizontal and vertical frequencies it is being driven at. I plan on scanning the GIGI brochures I have for inclusion on bitsavers shortly. Regards, Mark

EDA Electronics cards??? got a bag of them duno what they're from

by tshoppa＠wmata.com

The form factor matches up to the Vector 22/44 0.156" card edge physical form factor standard. Which doesn't narrow it down at all. Millions of custom industrial systems (some micro-based, but most not) were built using these plugboard style systems from the 60's through the 80's. Vector sold card cages and proto cards; the one-offs usually used the proto cards but something that was made in small to medium quantity might have used a Vector card cage (perhaps hand-wired) and etched PCB's. Sometimes the backplane was a simple bus in the computer sense but usually not. Looking at the chip logos and mix of analog/digital I'd suggest this is from the late 70's/early 80's and is some kind of DAQ front end or perhaps digital-math servo system. You can narrow the date range down from looking at the date codes on the chips.

Well, I suppose it depends on your usage. To me, an 80G drive is huge; I can't generate relevant content fast enough. To someone who stores movies on their hard drive, it's unbelievably small.

Installing OpenVMS Software

by cool1＠thecoolbears.org

I have a VAX that I like to play around with. I don't know VMS very well, and it's fun to learn new (well ok, maybe VMS is old now) things. There's an application that I would like to compile, but it depends on bison. I'm trying to compile bison, but that process seems to depend on MMS. I'm assuming that MMS works like "make makefile" and you do "mms whatever.mms" to make the app. MMS doesn't seem to be installed, so I registered and loaded the license. The SHOW LICENSE command says that the license is there. Now I need to install the application. I have the Montagar CD mounted and I can browse it's tree structure, but I can't find the kit that includes MMS. I thought maybe the C language kit and I tried: @SYS$UPDATE:VMSINSTAL CC064 DUA2:[CC064.KIT] ...which reinstalled C, but no joy on MMS. Any suggestions?

seeking ExperLisp by Expertelligence for Macintosh

by nigel.d.williams＠gmail.com

I used this in the 1980s and would like to get a replacement copy for the one I lost - thanks. Last year on eBay someone purchased a large collection of Macintosh diskettes, one of which was an ExperLisp diskette, so if that person is a cctalk-er I would appreciate a reply. It was released for the Mac 512K and later Macintosh.

TTI 8510 Manual and/or switch settings...

by lbickley＠bickleywest.com

I recently acquired a clean TTI (Transitional Technology) 8510 8mm SCSI tape drive. I've searched Google extensively - but have found no manual or even a switch settings guide. It emulates an Exabyte EXB-8200/EXB-8500, a DEC TK50Z, an IBM 2.3 GB or the native TTI 8510 (from Google). It has twelve dip switches, three of which I've found to be the SCSI address - the others are a mystery. Does anyone have a manual or guide to the switch settings for this tape drive?

Interesting email addresses of old...

by mark＠wickensonline.co.uk

I was just trawling through some of my file archives and found my old email address when at University: mwickens at vax2.luton.ac.uk - from 1993 to 1996 At the time I wasn't really into VAXen, but subsequently have wondered about the VAX that handled my emails during that time. In the last year a new Alpha system came online, and new email accounts were set up on that box. Anyone had interested email addresses in the past, or an email address which represented a nostalgic time in their life. The fluidity of email addresses interests me academically and professionally - I work on systems which traditionally have involved postal communication, but are moving over to email based communication. This represents a challenge due to the fluidity of email addresses over the course of the years. Regards, Mark.

New rsync mirroring at trailing-edge.com

by shoppa＠trailing-edge.com

Last weekend I promised to enable rsync access to the archives (and mirrors) here. I've set up the following rsync (no password required) archive sets here: ftp : Public rsync access to ftp://ftp.trailing-edge.com/ area pdp-10-tape-images : public rsync access to the PDP-10 tape images, i.e. http://pdp-10.trailing-edge.com/ bitsavers-mirror : public rsync access to my local bitsavers mirror, i.e. http://bitsavers.trailing-edge.com/ Suggested rsync commands would be, for example: mkdir ./pdp-10-tape-images rsync -rlptu -v www.trailing-edge.com::pdp-10-tape-images ./pdp-10-tape-images mkdir ./ftp.trailing-edge.com rsync -rlptu -v www.trailing-edge.com::ftp ./ftp.trailing-edge.com mkdir ./bitsavers-mirror rsync -rlptu -v www.trailing-edge.com::bitsavers-mirror ./bitsavers-mirror Realistically the pdp-10-tape-images and ftp sites don't change often, butm my bitsavers mirror is kept up to date. I like to think my outgoing bandwidth (20 Mbit) is pretty much infinite, this looks like a good way to find out :-) ftp racks up to 3.5 Gbytes. PDP-10 tapes racks up to 2.2 Gbytes. And bitsavers-mirror racks up to 126 Gbytes. Tim.

Somebody I know had a Volvo V70 that just refused to start one morning. Nothing obviously wrong, it just would not start. It had to be towed to a Volvo dealer. IIRC the problem turned out to be that two of the car's computers decided they didn't want to talk to each other. A software upgrade fixed the problem. It may even have been the case that none of the computers had to do with engine management. The owner of the car is very clueful about hardware, software and cars, but it would still have been a major undertaking for him to even find the problem, let alone obtain the software upgrades. > And I realyl don't understnad why service information is not supplied > with (or at least available for) devices that are almost cetainly > goign > to be owned and used by people with eelectroncis knowledge -- > soldering > stations , mutlimeters, 'scopes, etc. I've still not bougth a new DMM > after my Fluke failed last year because I've yet to find a > manuafactuer > who will supply a service manual. > Because they want you to either buy a new unit, or send the unit to one of their own facilities to be repaired? In case of car manufacturers I believe a significant portion of their profits comes from spare parts and service. Do you have a mobile phone? Modern ones seem to be designed to break down slowly after about 18 months, they are full of custom parts, and the people who repair them do their best to drive you mad. My work phone is (hopefully) being repaired right now. It is 17 months old, the display went permanently blank around August 6th, and the repair people have most likely not started working on it yet. I shall probably have to wait another 2 weeks for it. /Jonas

More DEC Bad luck.

by bdwheele＠indiana.edu

I'm convinced that my house was built over an Indian burial ground. Or it was owned by someone heavily invested in everything but DEC... I powered up my AlphaServer 1000A last night and it looks like it has problems too. It powers up and the drives & fans spin up. The lcd showed 'ec.' only once, every other time it is blank. Nothing out of serial port 1 and the onboard VGA never initializes. I tried setting the 'failsafe boot' jumper and I put a blank floppy in the drive just to see if it would try to read the floppy and it didn't even try :( Any ideas at all? So now it looks like both of my alphas are shot (the PWS500au never initializes video, does anything with serial, and turns off all diag lights) and my DECStation 5000/120 has a bad power supply. On the plus side, all of my terminals still work and both of my vaxes (MicroVAX 3100/90 and VAXStation 4000/90) boot to VMS without problems. It brings me to a question: are the alpha systems inherently fragile? The dead DECStation is an obvious hardware issue due to (probably) a leaked capacitor which is understandable due to its age, but the Alphas are just hosed in a software kind of way. Brian

WTD: 0.156in 2x10 or 1x10 edge connector for Motorola/Displaytek M1000-355 CRT

by classiccmp＠philpem.me.uk

Hi guys, I just picked up a Motorola M1000-355 CRT monitor (5in diagonal open-frame industrial "thing", circa Jan 1987 so almost as old as I am!) at the hamfest today.. Problem is, I don't have a suitable mating connector for the card edge connector... It's a 10-pin single-row card edge connector, with a 0.156in pin pitch, although I suspect a dual-row (20 pins total, 10x2 layout) would work fine too. These are listed as "US stock only" or "Discontinued, obsolete" by every supplier I've tried... Does anyone have one squirrelled away in a box somewhere which I could buy or have (he says with a cheeky grin) ? Or possibly a lead on a source for one or two of these, ideally with keypins (but the latter isn't essential)? I'd also rather like a copy of the datasheet for the monitor module if anyone has it... I have a pinout (it's the standard 10pin pinout as posted by Tony Duell quite a while ago -- IIRC either the Kaypro or Osborne monitor uses the same pinout) and a sneaking suspicion that it's CGA-spec, but no hard proof. I do know that it pulls 12V DC at about an amp -- the first value is printed on the PCB, the second was provided by the meter on my bench supply!

Soldering stations - OKi-Metcal, Pace or something else?

by classiccmp＠philpem.me.uk

Hi guys, Well, we've got a thread on desoldering kit, so I'm going to start one on soldering stations... :) It seems my love-hate relationship with my Antex 660TC soldering station has finally become one of almost pure hate. I sat down to assemble a couple of DiscFerret boards tonight, and after about 40 minutes the handle of the iron was too hot to hold. Tried again with the other iron, same story. If I hold it any further back, then the whole thing is completely out of balance... So I figure it's time for a change. Hopefully to something which won't try and roast my fingers. I've narrowed my choices down to two manufacturers -- OKi-Metcal and Pace. This is basically because they're the only two "professional" brands Farnell carry (I did look at some of the Weller soldering stations but they don't look much better than the Antex). I'm looking for something that'll suit SMD work -- ideally one which has "mini-wave" soldering iron bits (aka "hoof" bits) easily available, and is designed for lead-free work. I do run an SnPb line as well, though I'm slowly phasing it out (once I run out of 60-40 solder, which might take a while...!) At the moment the front-runners are: - Pace WJS100 (with TD-100 and Instant Set-Back aka auto-standby). Not overly keen on this one, seems overpriced when compared to other Pace kit (especially when you consider that the WJS only works with certain soldering bits and one type of handpiece) - Pace ST50 + TD100. Seems about the same as the WJS100, but will run the tweezer handpiece and a wider variety of bits. Catch is, I'd have to special-order this from Pace UK if I wanted the ISB option (Farnell don't stock the ISB "cubby" / iron stand). - Metcal MFR-1110. Cheaper than the Pace (or so it would seem), cheaper tips. Also seems to have "auto standby" as standard. What concerns me is that it seems to run at a fixed temperature, though OKi/Metcal claim that SmartHeat makes this a non-issue... I'm not convinced... Has anyone used any of the above, or anything similar? Are there any other brands (or other soldering stations from the above manufacturers) that I should look at? Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
