QX-10 / terminal software

by jules.richardson99＠gmail.com

Morning all, I thought I'd try and get the ol' Epson QX-10 running as a dumb terminal. AFAIK, there's nothing on the 'standard' set of disks to do this (e.g. valdocs has the 'mail' program which is aware of the serial port and which I think can talk via a direct link rather than a modem - but I think its functionality is all quite high-level and there's no 'terminal' mode). So... MEX looks like a possibility, and an overlay for the QX-10 seems to be available (although I'm not sure how much work is involved in merging them yet). Does anyone know of any other options[1] which will work with the QX-10's serial hardware? Or, does anyone happen to have a QX-10 enabled version of MEX archived already? [1] does CP/M abstract serial hardware into a set of common calls, or is that outside its scope? cheers Jules

Need Kermit for Xerox 820-II in .IMD format

by xmechanic＠landcomp.net

(Think I may have goofed on my earlier post (excess formatting)) Hiya, Just wondering if anyone has a Xerox 820-II with CP/M 2.2C that already has Kermit installed, that could make a Image Disk of it and upload it someplace? I have Dave Dunfield's Image Disk program, and I've successfully transferred several programs to the machine this way, but I'd like to have a comm program to transfer stuff, as I'm using a modified cable from the existing 8" floppy drive to an old win98/DOS PC for transfers, and I don't like to disconnect and connect those 50 pin edge connectors on and off the boards too many times. I actually have the .HEX files for the machine, but I tried to get them transferred with 22disk, and it doesn't seem to like 8" drives too much (ver. 1.42 or 1.44). I also tried the host terminal transfer, but hex files seem to wreak havoc and don't transfer properly. So I'm kind of stuck between a rock and a hard place. If anyone can help out, it would be greatly appreciated! Thanks. Dave Land Land Computer Service

online cross reference?

by sales＠elecplus.com

Is anyone interested in hosting an online cross reference for components both small and major? I have a fairly large (3000+ line items) of cross reference for hard drives, CDROM, CDRW, NIC cards, video cards, etc for computers and servers that I would be willing to contribute in spreadsheet format. Also MANY hard copy sheets of old printouts for parts that go into HP and IBM servers. Cindy Croxton _____ No virus found in this message.

DG Nova repair etc.

by RolexTM＠gmx.de

Hi all, Tony, thanks for your input, we will check the PSU on Thursday when we get to the machine again. as Christian pointed out, the problem is not so much the pure amount of components but the puzzle game of identifying them since they have been relabled. Whats definitely worse when comparing to out old VT100 is that the DEC manual has one complete definitive service manual that covers all schemes and logic. For our NOVA i failed to find a comparable thing. I have constantly to go back an forward through all kinds of docs. Again I may be unable to find a "real" service manual, if you know any let me know ;) Bruce, I am looking forward hearing from you. It would be great if you come up with anything helpful before Thursday so we can check everything out. Dwight, we are currently missing the exact schematics for our machine. I hope thats where Bruce comes into play. The only real schematics i found were for the NOVA 2, and a quick glimpse showed that the machine is different (at least the layout of parts). None the less we will keep our eye on the clock(s), i guess it will do no harm and make our scopes and logic analyzers happy ;)

networking via SCSI

The machines are configured as multiple initiators and can send storage requests over the SCSI bus to shared disks or arrays. You still have to have another connection (usually Ethernet) for machine->machine cluster communication. While I haven't looked into it much beyond pinouts, DEC produced the proprietary DSSI which, in some cases, used SCSI ASICs - indicating that at some level it was similar (HSD-05 used, I think, an Emulex at either side. Can't check now, but can later). The protocol was different, and cluster communications could go over the DSSI bus between machines. I'm not sure whether the lack of a similar setup for SCSI is more because of impossibility or because Fast/Gig Ethernet came about and there was no longer much of a reason to not use the Ethernet for cluster comms.

HP-UX 10.20 or less for series 800

by saquinn624＠aol.com

I have an old G70 that's currently running HP-UX 11 (I had 11i v1 on it for a while - bit slow for that, and the patches would break it if you weren't careful). Anyway, I have a workstation for all my HP-UX 11 needs and was kicking around the idea of putting 10.20 or 9.04 on the beast to give it a bit more vintage flair, but all of the CDs I have and have seen have been 10.20 for the 700s. Anyone seen a 10.20 for 800 around?

Data General Nova

by RolexTM＠gmx.de

Hi Bruce, thanks for taking your time to answer my mail! Sorry to leave out details, i know how frustrating it is if people forget the important bits of their problems ;) I have (at least sighted) all documentation from bitsavers: http://bitsavers.informatik.uni-stuttgart.de/pdf/dg/ and read a good amount of code and documentation of the simh project (because i would like to build a media emulator for this machine later....maybe) My main problem is that most of the stuff from bitsavers seems to be for newer machines that have a builtin ROM? My machine does not have the program load option (at least theres no switch for it) and i was under the impression that all documentation i found somehow just loaded a stored program for the check procedures. Am i wrong with this? So, in short i did not find any checkout procedure that looked adequate for my machine so i just hacked in some small asm programs that at least ran on the simulator. Actually, the machine runs simple nop jumps at least 1: jmp 2 2: jmp 3 3: jmp 1 If i remember right when running this program it did not even hang itself up (aka you could "stop" the machine). But i prepared the popular "Hello World" asm example to run without RDOS, and it obviously failed at least because of the stuck ACs. I mean, how can you write anything meaningful without using an AC? ;) By "Reset" i mean pushing the reset switch up when pressing down for "stop" does nothing. Again i may be subject to interpret the meaning of STOP and RESET wrong. Clearly this machine is confusing me ;) We will examine the power supply for sure! It bugs me that we did not think of that, since for now we only get to the machine once per week. We may also have the option to take it home though.... Also a friend of mine (which should be registering here soon, too - and is more experienced than me when it comes to electronics) said that the machine was acting strange when he first powered it up after it sat for a week (aka cold). Maybe that points to another aging/heat related/power supply problem. Thanks for clarifying the internal structure of the machine. I was not aware of that although i looked at alot bus pinouts, transfer timings, signal descriptions etc. See above, confusing! The third party board is unidentified for now. We tried to run without it but saw the same error. We also already noticed that the machine runs only with 2 CPU boards and nothing else, at least the PC counts and the ACs still deposit and load. I promise to take quality photos of anything you like once we get back to the machine. I apologize for the bad photos my phone makes. best regards Alex On 02/15/13 18:03, Bruce Ray wrote: > G'day Alex - > > Your e.mail begs many question. > What documentation do you have? > Are you following the checkout procedures in the DG hardware manual? > What "simple programs" can be run? > What does "reset the machine" mean?

3B2 Winchester (ST4376N/CDC Wren)

by saquinn624＠aol.com

Pulled it out, reseated the cables, checked the connections, plugged it into a big enough power supply, and gave it another go. Spun up, head load or lock solenoid clicked, waited about 4 seconds (no sound of seeking), spin down. Sounds like the problem might be somewhere in the head positioning or voice coil/drive.

I vaguely seem to recall I had a DG equivalence list in the 90's. Or maybe confusing it with something else and my memory is just a red herring. Maybe Carl Friend has it? Poly Paks always had lots of house-numbered TTL, I'm guessing floor sweepings from DG :-) When I had to read DG schematics, if the part didn't have a standard number on it, it was usually pretty obvious from pinout or other parameters, what the standard part was. By the time the Eclipse came along, those were just chock full with bipolar PROM's. Tim

PDP-9 Restoration at the RICM

by michael.99.thompson＠gmail.com

Warren Stearns and I have been working on the PDP-9 at the RICM. Yesterday we got the core memory working and started debugging the processor. Quite a milestone for a 44 year old system. All of the operate instructions seem to work. The JMP and ISZ instructions are flakey, even when single stepping. This could be a microcode problem, or a problem with the data multiplexers. It is an interesting machine because it is microcoded with read-only core memory. I am not sure why they used core for the microcode. Maybe just a board with a bunch of diodes would have done the same thing and would have been a lot simpler? I am finding the schematics a challenge because they were created before ANSI or IEC standard logic symbols were invented. Eventually I will understand the symbology. Some of the design is a little strange because you can abuse DTL logic in ways that TTL will not tolerate. Lots of delay lines where you can adjust the delay by changing wire-wrap on the backplane. Lots of pulse amplifiers to improve fan-out and reshape signals. You can read about our debugging progress here. http://www.ricomputermuseum.org/Home/equipment/dec-pdp-9/pdp-9-restoration We need to fix the paper tape reader so we can load some of the diags. We are a long way from connecting the TC-59 and the TU20. I suspect that getting the TU20 working will be a challenge. -- Michael Thompson

by rampaginggreenhulk＠yahoo.com

I disagree. By comparison it lacks features compared to the Tandy. As does the Sanyo. They share enough to make the comparison. I wouldn't for instance make the same comparisons between the 1000 and 2000. They're just too different, but in many respects the model 2000 is a more powerful machine.

Wang VS7150, VS7010 and 3270s on eBay (London, UK)

Main processor is a VS7150. This was attached to another large cabinet which houses three large and heavy hard drives (believed to be 454MB). There is also a VS7010 and a VS75E, the latter of which seems to be missing some covers. There are also somewhere between 4 and 6 3270 terminals (see photo of single unit). There are also a quantity of the removeable disk-packs, which, if my memory serves me correctly, used to be 300MB. There is also an old line-printer with acoustic hood and some boxes of the flowline paper. ... Current price is GBP 950 and it's available for collection in London (UK) - seller is also willing to ship it anywhere in the UK. http://www.ebay.co.uk/itm/221183449983 Not affiliated with the seller in any way. -mj -- Michael-John Turner mj at mjturner.net <> http://mjturner.net/

I think what broke the Jr has more to do with people coding to specific BIOS locations, which broke any "near" clone. In 1983 when the PCjr was introduced that practice was rampant.

It would seem his point is since it was offered as a PC substitute, it should have been more "clone" then it was. While nowhere near a clone in the purest sense, an nearly exact copy, like a generic Taiwanese clone, it still should have been a more workable substitute for a PC. The AT for instance, while could be considered something of a steroidal clone, was worlds more compatible then the Jr. And add to that company's willingness to work around the AT's minor incompatibilities you had a ready upgrade solution to the PC. I'm not that familiar with the JX but something like that should have been the Jr. Or the model 25s. Some expandability, in reality could have been a good secretary's unit (strangely the model 30 seems to have been used more along those lines).

RGB analog, sync on G to VGA or HDMI?

by chrise＠pobox.com

Are there any recomendations for a converter that can take RGB with sync on GREEN as input and produce a VGA (or HDMI) output suitable for driving a modern LCD? I seem to be accumulating numerous older pieces of gear that produce RGB output and space and reliability of the old tubes to which they connect is becoming more and more premium. Would like to be able to use an LCD as an alternative. A couple DEC VT240 came my way this weekend and they will need some TLC to restore but the VR240 that came along with them is in even worse shape. I'll give it my best shot but ability to use an LCD as Plan B would be nice. Any recomendations from success? Chris -- Chris Elmquist

DOS (PC) FTP server testing needed

by mbbrutman-cctalk＠brutman.com

Hi, I made some changes in my TCP/IP code to make it behave better when packets are lost and it has to retransmit. The old code used to wait a fixed amount of time before retrying, which was painfully slow on a local connection. The new code is adaptive and should work much better on a wide range of connections. If you'd like to help me test it I have my PCjr running the mTCP FTP server with some old computer pictures, some software, and some text files. (I'll add more during the day to keep it interesting.) You can connect by going to the following address: ftp://96.42.84.69:2021/ That URL should work in most browsers (Firefox, IE and Chrome). Chrome tends to be a bit of a pig and it tries to preload the content that it finds, so if you see it going slowly it is probably due to multiple connections. The poor PCjr is only setup for 9 simultaneous connections. If you use an FTP client anonymous FTP should work fine. Note the non-standard control port - 2021. Which also means that if you are using a real FTP client (and not a browser) you should be using PASSIVE mode. (Port mode with a non-standard control port confuses most firewalls, and they won't pick it up. Most browsers use PASSIVE mode by default.) Uploading is not turned on for this test, but if you are dying to upload contact me and I'll give you the password. Fun facts: - The machine is a PCjr with a jrIDE sidecar, 20GB IDE hard drive, WD8003 ISA Ethernet adapter, NEC V20 CPU, and an IBM PC 5150 keyboard. Yes, this is the same machine that was recently maligned on the list. ;-0 - If you want to see how the TCP/IP code is holding up you can get statistics by using the "SITE STATS" command in a suitable FTP client. - This is a DOS machine - you have to use DOS filenames and paths, except for the directory delimiter - that uses the standard forward slash. (Using the DOS backslash was too difficult for most clients and browsers.) Also, if you use MGET remember that you have to use *.* and not just * for a filespec. Comments and bug reports are welcome. Use good judgement to avoid cluttering up the list too much ... Mike

Introduction and IBM 1130 replica project

That one has a soft spot in my heart to the extent that I can still remember the numeric opcodes for many instructions. The 1401 occupies a similar place in my memories. Little IBM boxes were really cute. > > --Chuck At the moment, I use a high speed stream protocol over USB, via the brilliant fpgalink library by Bruce McClelland ( http://www.makestuff.eu/wordpress/software/fpgalink/ ) to a bit of python code on a PC which takes files and sends them as card column signals to my 2501 reader emulation logic in the fpga. I am mapping all the signals from the 2501 to the adapter circuits in the 1130, timing everything and modeling state as close to a real 2501 as I can determine, so that it appears that the photocells are detecting holes at the right time as the card virtually slides through the emulated transport, but the content of the columns that get turned into lights are stuffed into a FIFO by the link from the PC. However, someone has offered a small card reader that I will be gratefully accepting and utilizing. I plan to map the real reader as the 2501 and use my alternate 1442 reader/punch emulation over the fpgalink channels so that I can both read real cards and read files on the PC as virtual cards. Yes, the 2501 just delivered to the 1130 one bit for each of the 12 card rows, exactly what was punched in that column. The 1130 programmer would convert the Hollerith coded characters into whatever other coding they wanted in their program. Boot mode wired the signals a bit differently to provide a 16 bit result to the 1130 that was usable as initial program load instructions, that is done in the 1130 adapter logic, not in the 2501. Finally, various forms of binary coding were used in the 1130, such as the user program format and a special binary mode used by diagnostic programs, but all of those are just the status of holes in a column sent as 12 bits plus 0000 to form an 1130 word. My python program converts ascii files to Hollerith, as well as delivering binary mode files directly as card hole images. I don't personally know of any fpga emulations of 1620 machines, but there are excellent simulators available.

Cyclone CVME961

by seefriek＠gmail.com

From: Benjamin Huntsman <BHuntsman at mail2.cu-portland.edu> > > Here's an odd one... > Anyone here ever seen, heard of, or have a Cyclone CVME961 board? > > > I have. The 961 was a pretty nice i960-based general purpose embedded controller that got a lot of use in real time systems and, as I understand, a lot of military stuff. i960CA of various speeds, memory, 2 serial ports and a mezzanine expansion scheme Cyclone called "Squall" that had a few options (I know there was an async serial card, think there was a SCSI card and ethernet card, but can't recall anything else). Not sure what specifically you want to know, but there is a good bit of info out there still at Google reach. Unfortunately, I decided i960 wasn't something I had time to play with, so all of mine are long gone. BTW...what you really want to find if this sort of thing is your kink is a CVME-965. 960HA, VME64, private and shared memory and 2 x Squall 2 mezzanine slots. The Squall 2 slots were much more useful, as Cyclone made all sorts of interesting options for it. I had, at least, SCSI, 2-port ethernet, various serial cards, some digitial input cards, etc. I sorta-kinda remember there was an ATM card; I didn't have one. Made whipping up a router on a card pretty easy, even if the preferred dev environment was Ada.

You mix the binder and oxide together in a thick paste and spread them on the sheet. I suspect that the thickness of the coating is regulated by a "doctor blade" setup. The coating is cured and then round disks are punched--the result is called a "cookie" for obvious reasons. It's then verified and inserted into the jacketing medium, sealed and packaged. Not so fast bucko. Got to flip the blankee over and coat that side. >The oxide coating on a 5.25" DD floppy is not much different from that of VHS videotape. I suspect that the demise of floppy manufacturing to more a case of video- and audiotape dying off. I would think what put the kybosh on both were advances in optical media, which became a solution for computer storage earlier then video. Both useful.posts though. Anyone think this can't be done? Is choice of substrate that critical? Question in my mind is how to control the thickness. This is why I had thought spraying would be appropriate. Maybe it is.

DG Nova repair etc.

by RolexTM＠gmx.de

> The original Nova has a 4 bit ALU What do you mean? I think i did not get your answer. >> When I got my Nicolet, I had a similar sounding problem.It turned out to be a missing clock.Of course, yours may be soemthing different but you aregoing to need some schematics and a scope to track down.( I did mine without a schematic but I was lucky ).Dwight We already sighted most of the pdfs and schematics at bitsavers and simh. We have a scope and logic analyzer and some experience in component level repairs of electronics. This machine is just a bit harder to diagnose than for say our old VT100...the documentation is overwhelming and my brain has not adapted to it well atm ;) so i just hope to get somebody that has intimate knowledge of the machine.... The problem of the machine only running on single step and not on "run" may well be related to a missing clock, although i wonder if even single instruction stepping would work without clock since it also needs some form of clock to single step through one asm instruction...although i might be on the wrong train since there may well be more than one clock inside the machine.

It inspired me to learn hardware design and electronics and to aim for my project. Richard designed his machine by designing hardware that would match the Functional Characteristics manual, analogous to how Amdahl designed an IBM compatible system by adhering to the Principles of Operations but adopting their own unique design within the machine. He did not have a goal to emulate the hardware console functions such as Single Step, Single Memory Cycle, Interrupt Run, Load, and so forth. Since I first got hands on experience with computers on an 1130, learning by using those controls and watching what my code was causing to happen, I wanted to recreate to that level. My machine is built to map almost exactly onto the logic gates of the 1130, as I used the ALDs (automated logic diagrams) to recreate the system. It is designed to run at the same speed as the physical 1130. It is therefore a cycle by cycle faithful recreation, allowing someone to see what changes when releasing the Start key in Single Step mode at cycle T4 of instruction phase E1, which is phase B of the clock. Certain conditions change or actions take place on specific phases of those cycles - this recreates them. I also mapped all the hardware adapter logic faithfully and built hardware to emulate all the signals that came into the 1130 from the peripherals. As a final step, I adapt real hardware I have, an Electronic Typewriter 50 (selectric ball type machine), to link to my hardware emulation so that it behaves the same. My keyboard is a photocell driven partially mechanical unit from a keypunch of the era, interfaced to link to the 1130 adapter circuits and present the exact signals that would come from the real 1130 keyboard hardware. I built the display light pedestal above the console printer to scale, as another example of my obsessiveness. My aim is to replicate the experience of running an 1130 hands on. This certainly is no denigration of the emulator built by Richard Stofer - it provides higher performance than a real 1130 and from a programmers standpoint is a truly faithful replica. For most people, that is all the recreation they want. Beyond that, there are software simulators such as the one hosted by Brian Knittel at http://www.ibm1130.org with a full set of 1130 software at the same site - highly recommended. This project has allowed me to meet a number of great people who have offered advice, aid and a supportive ear as I toiled away - I try to credit them all in my blog, but it is possible I haven't mentioned all of them. I am also indebted to Al Kossow and the Bitsavers archive for availability of ALDs and other documentation sufficient to produce this hardware level recreation. > But for the 1620 nothing so far. There is Java based emulator but the only software thats been converted is the diagnostics. Al did load up the other stuff he has to bit savers , but I havn't had time to look at it, as I got distracted by a project to connect some Creed equipment from a Ferranti Pegasus to a software emulator.... > Sounds like you are having some fun yourself.

Question about NeXT 17" B/W monitor

by IanK＠vulcan.com

Does anyone know the part number for the CRT in a 17" NeXT monochrome monitor? I've cast about for a schematic that shows it to no avail. I've opened up the monitor (N4000A), and the number is not evident. The internal frame bears a Sony name and number, SMC-311A. I fear the number may be hidden under the yoke - which I'd rather not pull free, for obvious reasons. Before I start getting dramatic with this thing, does anyone know the part number? I'm going to try rejuvenating the CRT, per a comment by Ethan a little while back (I acquired a B&K for $9 on ePay). Nearly all of the 17" CRTs have the same switch settings, but count on Jobs to have picked an off one. :-) So it seems wise to tap the collective wisdom before just crossing my fingers. Thanks -- Ian

Silver-oxide cells lifetime

by cclist＠sydex.com

For the third time, I've had to replace the three 357 silver-oxide cells in my HP16C calculator. That's probably very close to 15 years on average between sets--not bad. What surprised me was that one day, the thing was working nicely and the next, it was dead--no display, nothing. A voltmeter confirmed the power failure. I suspect the cells get pretty near their shelf life in this application. Is it usual for them to reach the end of their shelf life so suddenly? --Chuck

It's probably the original disk, as it has AT&T stickers on it. Plugged into multiple computers and external drive enclosures it spins up, head load click, then spins down. I've tried reseating connectors and checking jumpers, no change. I don't know what the jumper on the bottom side of the lowest PCB near the SCSI connector does, and there are two empty DIP sockets on the bottom of the drive that could possbly be a part of the problem. I haven't taken a scope to it to trace out the signals yet and see if an amp died.

Gold (WAS Re; 3B2 floppies)

Gold plating usually uses cyanide compounds, which many people consider "nasty chemicals" (certainly chemicals that one needs to work with carefully, but pretty common for both plating and case hardening). If you're using cyanide anyway, you might as well go ahead and use a modified MacArthur-Forrest process and not bother with the electricity. Pour your gold-containing objects in a dilute cyanide solution, recover the gold by either electrowinning or single-replacement with zinc. At the end of the day either way is a lot of work for little gold.

reasons to keep a Turbo XT clone.

by saquinn624＠aol.com

There was a question about what manufacturer made it. It looks like a generic Taiwanese whitebox, sticker on the back says "Mega 4000", sticker on the front says "AT Light" (+1 for them getting the spelling right instead of using "Lite", -100 for their marketing department appearing to have no idea what "AT" means). I guess I'll hang onto it for a bit, anyway. I have a SCSI card that will work in it and an old VGA card.

WANTED: TM8E magtape controller for Omnibus

by hachti＠hachti.de

Hi folks, I already have lots of stuff - but there's always something missing! Is there anybody out there who 1. owns a TM8E magtape controller? and 2. who can imagine to give it away? I have a few TU10 drives that dropped in with a PDP11 some time ago. It would be awsome to get one of them running on a 8/e system. I know that there was a magtape controller. But I'be never seen one. And I don't know anyone who has one. At one point in newer history I found a H960 containing a 8/e and a TU10. But when opening the 8/e, it was empty - no TM11 controller :-( Any hints appreciated. Kind regards Philipp (I'm currently getting my collection reassembled and rearranged. Most of it will be tied together in the place where I'm living. Therefore I have begun to play with minicomputers again - after a few years of very low activity and a widely spread nearly inaccessible collection. And I will sell some stuff!) -- Dipl.-Inf.

DG Nova repair etc.

by RolexTM＠gmx.de

Hi all, my Name is Alex, me and a friend of mine have been actively participating in a computer collection, mostly repairing stuff and bringing it back to life. We have numerous old apples, vaxes, decstations, suns, next etc and some real weird old stuff ;) Lately we discovered a DG nova standing in a dark corner of a storeroom. We have absolutely no peripherals, just the bare machine. It has 2 CPU boards, a general IO card, 2 Memory boards and some unknown third party controller. The Machine as it sits now has 2-3 problems (at least): 1: Somehow the "desposit next" switch does not work as expected by not incrementing the adress sometimes. Doing a deposit-examine next-deposit works, so thats a minor problem. 2: Simple programs run fine in single step mode. Press RUN and the machine seems to hang. You can not even STOP anymore, you have to reset the machine. Annonying, but to test the simple stuff single stepping also works.... 3: The biggest problem is: The ACs have numerous bits stuck on 1. It is the same bit pattern for all ACs. We can store and deposit the non-stuck bits, but all others remain a 1. With this behaviour its really really hard to write any meaningful asm to test the machine ;) Please see the attached Link for pictures of the machine and the bit-pattern of the AC. Since the AC Deposit works as expected and the error shows only when examining we are positive that the error is not in the AC Registers itself but somewhere where the switch location is actually shifted into the AC....or something like that. We are also struggling a bit to get all the documentation in a meaningful relation. So if you have any pointers on what to do or check, please chime in. If the machine gets back to life i have plans on emulating a storage device to run one of the available os-es. Should be doable with a microcontroller and some logic glue.....but it looks like a long way ;) See actual pictures of the machine here http://bigalpha.ath.cx/nova/pics/ori/index.html where you can also see the bit Pattern of the AC. I kinda wonder why its 1 11X 111 X11 1X1 11X I guess this should point us nearer to the point of failure. best regards Alex

Introduction and IBM 1130 replica project

by Carl.Claunch＠gartner.com

I just joined the group, although I have had a long time appreciation of vintage computing technology. I spent most of my career on the software, marketing and most other aspects of computers but not hardware. I have put together systems, hacked at things, but at a light level, until recently. I decided to really learn how to design and engineer, choosing a project that would expose me to many aspects and be a forcing function for developing quite a few skills. Not that this makes me a full bore EE or able to design at a current technology professional level, but enough so I could envision, design and make hobby items of pretty much any scope I wanted. The project is a replica of an IBM 1130, a low end mainframe contemporaneous with S/360 and sharing the same logic and other technology. My aim is to build one that is an experiential replica - one that brings me as close as I can get to the experiences and behavior I had sitting in front of the console hand stepping through code back at the end of the 1960s. The internals are based on modern FPGA but producing a cycle by cycle accurate system, faithful to the timing on the real machine. I have a blog detailing the work, my current state and goals, if anyone is interested, at ibm1130.blogspot.com Currently I am adapting an IBM Electronic Typewriter model 50 - a late model of the Selectrics - to serve as the console printer since the 1130 used a 1053 (Selectric based printer). The keyboard is being adapted from a keypunch keyboard, since the 1130 used the keyboard from an IBM 029 punch, and even where I am using more modern devices (a streaming link over USB to a PC to present card images to the peripheral adapter logic, I have made it timing and behavior faithful. The processor itself is working quite well, which is why I have moved the focus to peripherals. It is a very similar effort to that of Lawrence Wilkinson who has built a 360 model 30 and is also building peripherals at this time. You can read about the 360/30 project at http://www.ljw.me.uk/ibm360/vhdl/ I am hoping that members of this group will be able to share advice and information as I look to adapt something like an RK-05 disk drive, since it is very similar to the IBM 1130 drive, in a later phase. It is a truly quixotic project with no clear end, but will give me the excuse to dabble in all manner of old technology along the way. Hopefully many of you will have fascinating projects and experiences that I can enjoy.

3B2 floppies

by saquinn624＠aol.com

I have a 3B2/1000 that I'm trying to resurrect. The main Winchester drive is dead-ish (haven't written it off, but it's doing spinup-click-spindown so there's something big wrong), so I need to label a new drive. 3B2s are DSQD floppies, and I'm trying to figure out my best approach. I have the utility software in a disk image, but PCs usually don't ship with DSQD drives. I've found three possible options, but don't know if anyone's used any of them (or one that I haven't come across). (1) Mount the 3B2's DSQD floppy in a PC and try to write out the disk using it. Don't know if the PC's disk controller supports DSQD- I have a Compaq Deskpro 386/25 and a whitebox Pentium that I can try (2) modify one of the above machine's stock 1.2MB drives to spin at 300RPM. Don't know if it will write out the disk this way, but found mod. instructions here: http://www.oldskool.org/disk2fdi/525HDMOD.htm . May work, may not -I'm not sure how QD and HD head widths compare. (3) Replace the 3B2's 5.25 DSQD drive with a 3.5" drive and use 720K 3.5" disks to load it. Don't know how well 3B2 hardware would like this mod. I do have the proper DSDD media to use, so that's not an issue. I'd probably write the disk out with "dd" on Linux or xBSD if possble, as the network support makes getting the image to the writing machine much easier. Anyone been in this position before?

Tandy was questionable, but in reality not as bad as their rep. Cordat, Corona? Can't say. There were gujillions of Taiwanese boxes in those days. There were kit computers. I know I'll get egged for.this, but personally I think people were stupid to not build a clone from parts they mail ordered from the back of BYTE. I was in fact too stupid. Heard all the bed rap about evil vicious clones and their problems. I did return my Tandy 1000 once I found out I could get top of the line graphics and screen for the same price. But I waited over a year to buy a Multisync II then some months later a pernicious Tandy 2000. It would have held up longer if I wasn't constantly tearing it apart. Then I bought an Itt Xtra XP 286 hybrid. Wasn't bad at all, but once again I conxtantly twiddled with it's innards. Terry Yaeger once had a Hacker XT luggable. Maybe you should talk to him about it. And I'm telling you right now one of the rarest things in the universe are the later vga luggables that seemingly were churned out in the trillions.

One of the worst PC-compatibles/non-compatibles ever. Used a WD17xx floppy controller and ran (by CPU clock) slower than the 5150. Has a sort of VCR-look to it. No BIOS, except for a very simple bootloader--the BIOS had to be loaded from your boot floppy. > >One wonders what possessed Sanyo to make the thing. > >--Chuck I thought you liked the Silver Fox. Yes it had a 3.58 mhz clock, a hybrid digital-linear power supply, one red key and the largest return key you'll ever need. My dookey machine don't work currently. It may look like a vcr because it's so compact. Warez are available on the Tandy 2000 yahoo group or at least there's a recent threadc telling you where to find them. They had a following back in the day. Had better color graphics then cga if you could imagine.

I have been instructed in the mysteries and now know the proper terms to use. I have heard on good authority that even the priests and priestesses, Fred, Chuck, Allison,... utter such blasphemies in secretive chambers. So just don't swet it. Everybody's doing it.

And I'll have you know my Leading Edge/Sperry Model M runs rings around that Big Pyew. Supports 8" drives even maybe.

I AM UNWORTHY! I have recited the proper names of the D-shells 10 times through as penance. Scrub out That Which Shall Not Be Named Again and insert whatever descriptive term you prefer. Some marketer got to the manuals and put in That Which Shall Not Be Named Again, and the 3B2 is my first introduction to that particular format. I have been instructed in the mysteries and now know the proper terms to use.
