This weekend, we in MARCH are rescuing a Univac 1219 (early/mid-1960s military version of Univac 418). We're also getting a second parts machine and several teletypes (unknown model) and some spare parts. It's all coming from the Johns Hopkins University Applies Physics Laboratory. We hope to find out what these machines were actually used for .... if that's not secret. We're going to put the full 1219 directly into exhibit, and gradually clean it, etc. .... the parts machine and other stuff will go into storage. There isn't any storage or I/O console with this donation. Whatever .... we're getting some big iron that says "Univac" on it, so I'm happy. It will be displayed right next to our Straight-8. Permission granted to be jealous. ;) - Evan

Attacking NT "through MS-DOS"

by spectre＠floodgap.com

I'm not pointing this out to beat on poor Josh! I'm not! I just think it's an interesting angle that support for legacy 16-bit MS-DOS and Win3.1 apps has apparently lead to the unearthing of a 17-year-old Windows NT security flaw. The really amusing thing would be if something similar existed in Classic on OS X, or Rosetta. http://archives.neohapsis.com/archives/fulldisclosure/2010-01/0346.html -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- This message will self-destruct in five seconds.

A thyristor is a semiconductor version of a thyratron. A triac is something different and has *never* been called a thyristor even though it may be seen as two anti-parallel thyristors (which is not correct).

TU58 Tape Images for 11/750

by david_comley＠yahoo.com

Has anyone imaged the VAX RDM Microdiagnostic tape (tape #1) for the 11/750 ? I'm approaching a point on my 11/750 bringup where it would be useful to run some of the RDM diagnostics. In the absence of the real thing an image for use with a TU58 emulator would be great to have. Thanks, -Dave

Infoton Terminals

by iamvirtual＠gmail.com

I need to repair both of the terminals. :-( I am hoping to find a technical reference and in particular, a schematic. I have not found any information about these terminals yet. The first step is to identify the particular model. The model/serial number is given as an Infoton 1200, but I have not seen any references to this particular model. I am a software guy by trade, but am minimally knowledgeable about hardware. I have access to an oscilloscope as well as a logic analyzer (unknown if either work!).

Infoton Terminals

by iamvirtual＠gmail.com

I am looking for manuals on Infoton terminals. I believe these terminals are from the early 1970's. I searched using Google, but I have not found any documents relating to these machines. Via Google, it appears Infoton changed name to General Terminal. Here is the information I have about the terminals: Infoton Model: 1200/3 09200-G01-0M Serial: 26795 Any leads would be greatly appreciated. Thanks --barrym

C64 power bricks: What to do with.

by derschjo＠mail.msu.edu

Well, in my tenure as a computer-enthusiast/obsessive, I've amassed a number of the original, black Commodore 64 power supplies. (I don't know _how_ this happened, as I own only two C64s and one VIC-20...) I know their reputation as being ticking time bombs as regards reliability, so I don't use them. I assume they're not repairable, being potted power supplies. Is there _any_ reason to hold on to these, would anyone actually be interested in one or more of them, or should I just toss them (or turn them into doorstops, I suppose...) Thanks, Josh

Fwd: [alt.sys.pdp8] Another round of PDP-8 kits happening

by legalize＠xmission.com

This message has been forwarded from Usenet. To reply to the original author, use the email address from the forwarded message. Date: Thu, 14 Jan 2010 08:17:54 -0800 Groups: alt.sys.pdp8 From: Steve Gibson <x at x.x> Org: Gibson Research Corporation Subject: Another round of PDP-8 kits happening Id: <hing3n$5i4$1 at news.eternal-september.org> ======== Everyone... I expect that everyone here is aware of Bob Armstrong's really neat PDP-8 single board computer (SBC) kit, and its matching PDP-8 front panel kit. But if not, or to refresh your memory... It's a contemporary single board computer based around the Harris HD6120 single-chip, 12-bit PDP-8 clone microprocessor. It features a PDP-8 compatible RS-232 serial interface with a full BIOS "monitor" that allows the terminal to manage programs running on the PDP-8, single stepping, tracing, breakpoints, etc. It also exports a simple API that allows PDP-8 programs to access the IDE drive and other peripherals. The built-in IDE interface can attach to any IDE/ATA-style drive -- spinning platter, Compact Flash, or other non-volatile solid state drive (I went with small IDE SSDs.) Bob includes the device drivers for the PDP-8's classic operating system, OS/8, and a full OS/8 image is available for easy installation. (I wrote and provide a free Windows utility that installs bootable OS/8 on any drive instantly.) There's also an OS/8 "Games" partition image available that brings a collection of those. Various languages from the era, including FOCAL (Dec's interpreted BASIC-like language) and PAL-8 (the PDP-8 assembler) and editors, etc. are all there. This all means that with an attached drive and terminal, you can be messing around with a PDP-8 in its classic native environment. That's otherwise difficult to do on original DEC equipment. The front panel, which attaches to this board, is nothing less than a work of art and it was designed to copy the original PDP-8/e front panel as closely as made sense. Thanks to an efficient design using lots of CMOS and PALs to reduce chip count, the pair of SBC6120 and FP6120 consume about 150 milliamps when running with all lights illuminated. So it would even be practical to run the system from self-contained batteries. In early 2009 (about this time last year) Bob gathered a "critical mass" of interested classic computer enthusiasts and offered to make his beautiful creations available once again after many years. I purchased, assembled, and programmed three full kits that I'm very pleased with. Although I also own a collection of original DEC PDP-8s and PDP-11s, these kits are nevertheless something special. I recently completed publishing my work -- open-sourcing the PDP-8 software I wrote for Bob's front panel kit (a classic blinkenlights toy and a simple but challenging combinatorial puzzle) and I made flash videos of the results so that people who had not seen them in action could do so. (See link below.) As part of the publication of this work I have been coordinating with Bob Armstrong about the possibility of another round of combined SBC6120/FP6120 kits ... and that effort is underway. If sufficient interest can be generated -- at least 50 purchasers -- Bob has agreed to produce another round of kits containing all of the special, custom & programmed bits required to assemble the combination of an SBC6120 and FP6120. After its first day on the Net, we have about 15 people signed up so far. I am posting this note here, since I didn't want anyone who would WANT to know of this opportunity not to have learned of it in time to participate if they wished to. My web site's tribute to the PDP-8 consists of eight pages, the last one of which explains the details of the kits and provides a web-form for allowing interested people to declare their interest. Yesterday I announced the existence of the kits during my weekly Security Now podcast recording with Leo Laporte. The podcast goes live later today (Thursday, 1/14/2010), when we'll have an audience of about 80,000 receiving it then listening to it over the coming days. From among the few thousand listeners who were watching the recording live yesterday, we immediately received several declarations of interest... and they've been trickling in ever since. So, at the moment, we're looking good for achieving the required critical mass for another round. I have my kits, I don't need more ... but the kits are so nice that Bob and I wanted to help others get one. It seems unlikely that this opportunity will ever present itself again. Here's the page... http://www.grc.com/pdp-8/yourown-sbc.htm And if by some chance you are not familiar with these terrific kits, other pages in that area of my web site, linked at the bottom of that page, contain videos to give you a good idea of the final product. Here's to keeping classic computing alive ... and having a lot of fun doing so. :) -- ________________________________________________________________ Steve Gibson.

Honeywell Level-6

by hachti＠hachti.de

Hi, are here people with intimate knowledge of Honeywell Level-6 (Series 60) computers? Or documentation? I got two Level-6/06 machines. Those seem to be somewhat different from the rest of the line as they should be downwards compatible to the X16 machines. But I have no single manual for them. All I have are some Level-6 manuals talking about other machines. In one of them, the 6/06 is mentioned as special and "Series 700" (WHAT is that?!?) compatible. And that it is explicitly not subject of the manual and that it as its own manual that I do not have. I also don't have any schematics. Best wishes, Philipp :-) -- http://www.hachti.de

There are a couple of CQD-423/TM on eBay now that have been there for a while. Well under $1000, but more than most people would pay. I think it was a list member that recently sold a CQD-220/TM for around $100 on eBay. A couple of months ago I got a CQD-223/T off of eBay for around $60, which I then turned into a CQD-223/TM. An AVIV QSA S-box handle disk/tape SCSI adapter just went for $70 on eBay. Maybe the S-box handle adapters are less valuable to most people as they cannot be directly installed in a BA23 or similar without modification. -Glen

Lack of Posts on alt.sys.pdp11 and vmsnet.pdp-11

I normally watch theses two newsgroups. However, the last post on vmsnet.pdp-11 seems to have been on September 27th, 2009. Even for this low frequency group, that seems like a long time. For alt.sys.pdp11, the last post was on January 4th, 2010. Since there is usually a post every few days, this is also a long time. Has anyone seen any more recent posts? Perhaps the newsgroups server I use is not passing the posts along. Sincerely yours, Jerome Fine

Don Maslin (was Re: Collections, was: Be careful handling computer racks)

by vern4wright＠yahoo.com

Al, The short (or long) of it is that 1) I got everyone to stop calling Don's wife Winnie right after his death (8-2004) with the understanding that I would rescue his archive, package it, and make it available for everyone to download gratis (the Computer Museum here in SD was going to provide a platform and a bit of legal protection). 2) Winnie later declined to allow anyone to find, rescue the archive. There was no way to make her understand WHAT the archive was, much less its value. IMHO, she thought Don was just puttering in the garage that served as his shop. When it became clear that she would not keep her side of our agreement, and that my involvement was not going to be helpful, I suggested that Jay West contact her (I don't think he did). 3) A family member (who gave me the photos of Don and Winnie I sent to Sellam for the following VCF) told me that he thought the garage would remain as it was until Winnie died, or had it cleaned out by some junk hauler. I later heard that a lawyer was going to find the archive and rescue it; he supposedly thought it could be done in an afternoon. Rots of ruck, I thought. Don's shop was a physical mess, and the archive was not in just one computer, all nicely organized. Personally, I felt - and still feel sick about it. I OUGHT to have somehow forced Don to put the stuff on CD (I showed him how, but he hated Windoze with a passion and wouldn't play Linux either.) And he was an adult.... You can get all the details in the 2004-2005 ClassicCmp archives. Or write me back.

Fwd: Another possible round of partial SBC6120 & FP6120 Kits!

Hey folks, I'm forwarding this message from the Spartime Gizmos mailing list because I think there may be some interest here. Steve Gibson is trying to assess interest in doing another run of Sparetime Gizmos' PDP-8 clone, the SBC6120. This is a big job. The kit would include all the custom parts for both the SBC6120 single board computer and the (excellent, IMHO) FP6120 front panel kit. If you missed out on the last round of this kit, now would be a very good time to express interest in getting another run done.

Hi! I'd like to install on an old i386SX-16 mainboard. It comes along with 8MB RAM and 387-25 co-processor. My problem is that none of the 42 predefined HDD types fits my HDD, unfortunately not even the heads and sectors settings. (Missing some of the HDD's space due to a too small cylinders value wouldn't be a problem.) So I've got this mainboard. I cannot find a model description somewhere, only "REV 2B" and "COPYRIGHT 1989". Quality assurance sticker displays "HOWTEH Q.A", another sticker has "S/N: H 3204328" on it. During boot-up, "386SX/82335 Modular BIOS Version 3.04 (P24)" and "Copyright(c) 1984-88 Award Software Inc." are displayed, Ctrl+Alt+ESC gives the BIOS settings screen. (A photo can be found at http://lug-owl.de/~jbglaw/i386SX.jpeg .) My problem is that HDD settings 1 to 42 don't fit my HDD in any way. 43 to 47 contain all-zeroes values, so I guess they're all used for user-defined type. However, I cannot figure out any way to enter my correct C/H/S values. The displayed help is correct, but not exactly helpful to enter those numbers :) Maybe anybody recognizes this BIOS and can give me a hint? Thanks, JBG -- Jan-Benedict Glaw jbglaw at lug-owl.de +49-172-7608481 Signature of: http://catb.org/~esr/faqs/smart-questions.html the second :

Not to burst any balloons, but LC IIs are not particularly interesting Macs nor particularly rare. Some people like them for their form factor, but I wouldn't expect it to fetch more than a few dollars unless it has a lot of options installed. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- All science is either physics or stamp collecting. -- Ernest Rutherford ----

desoldering problems and technique (and amiga 2000 mod)

I went out into the garage and grabbed my propane torch (1 quart bottle size). I used it to heat the tip of the desoldering iron. That made the process go much faster since the solder melted instantly. Then when I tried to pull out the part, I heated the solder side of the board. That let the part fall out. Works great when you don't care about ruining the circuit board. :-) The 16-bit part of the isa connector was attached to the 8-bit part. I used a bandsaw to cut through the connectors and free the half I needed. Now it's time to solder the isa connectors to the 2000 motherboard. It's the scary part for me. :-) brian

Now you just need to do the 25 MHz => 33 MHz modification (couple of resistors) <http://homepage.mac.com/schrier/q605.html> or, if you're really ambitious and can find a MC88916DW80 do the 25 MHz => 40 MHz modification. <http://homepage.mac.com/schrier/q605_40.html> The latter may also require 80ns VRAM.

AT&T system V 386 Software needed

by g-wright＠att.net

Hi, Does anyone have a complete Package of AT&T SYS V UNIX for a the 386. I Have a AT&T 386/20 WGS computer that came with the software but when I looked closer, it does not have the boot disk (set up) or the license if it needs one. It has all of the rest of the floppies. I also have a few QIC tapes but with the same problem, no boot floppy. ESDI drive finally died so I need to start over. - Jerry

Floppy drive track-0 issues

by classiccmp＠philpem.me.uk

Hi guys, I've got a Citizen Z1DE-55A (3.5" 1.44MB PC) floppy drive hooked up to the disc analyser (it seems my Sony MPF520 has a duff head; it's reading garbage for one side of the disc). Here's the problem... - When the drive is selected, irrespective of head position, TRK00 is always inactive. - If the drive is given a seek command, it will seek to track 0, assert TRK00, but the INDEX and READ DATA outputs will go idle (float high). - The drive remains stuck in this state until power-cycled. Has anyone seen this kind of thing before? The MPF520 had a head-step lockout (if track0_sensor == active, then ignore STEP commands) but didn't crash out if you asked it to step. For what it's worth, the drive works fine in my PC... I just can't see why it's locking up like this. Also, am I right in thinking that pins 12 (DS1) and 16 (MOTEN) are the two I need to pull low to select the drive, if it's connected before the twist in the cable? And that DS0 and DS2 would be the select and motor enable pins (respectively) if the drive was located after the twist? Citizen are, as always, their usual "helpful" selves: "We don't make floppy drives, we never made floppy drives. LA-LA-LA, NOT LISTENING!"

FIDONET Node List 1986 #164 (June 13 1986)

by billdeg＠degnanco.com

I found an old FIDONET nodelist from June 13 1986 in my files today. This list is missing from any online archives I could locate, but I assume that there *must* be a comprehensive list from the 1980's, right? I have uploaded the nodelist here: http://www.vintagecomputer.net/fidonet/ 1986 #164 Here is the best archive I could find in a brief search of the web: http://ambrosia60.dnsalias.net/fidonet/nodelist.php Does anyone have any nodelists they'd like to share? If so send to me and I will post on my site. It's a shame that there is not more of a comprehensive nodelist archive. Bill

RAM for a VAXstation 4000 VLC

by jbglaw＠lug-owl.de

Hi! I've got my hands on a VAXstation 4000 VLC, unfortunately with no RAM. Though I'm not 100% sure, it seems it would work with fast page 72pin SIMM modules (FPM), as long as it is with parity. Does anybody of you have some spare (up to 6) 4MB FP-SIMM modules (= 24MB total) with parity for me?

OS/2-related stuff, low-$

by classiccmp＠crash.com

At work we're clearing out half my floor to consolidate office space. What we don't set aside or spirit away by EOD today will be cleared out by some contractor next week. We've been told repeatedly that the stuff will be trashed, not salvaged, and they don't use open/untended dumpsters. We also have /assinine/ [sic] rules about removal of anything and everything from the office - I can't haul out plain boxes of stuff, but if it fits in a bag or backpack I can slowly remove it. It's enough of a pain that I'm asking for a couple bucks more than just S&H, but if it will be useful to somebody I'll do it - just buy me a beer per item. PayPal preferred. There are two different boxed editions of C++ Set dev tools for OS/2, numbers 2.1 are in there somewhere. Don't have them in front of me or I'd provide details, but they both included media and some books. I can grab at least a half dozen shrink-wrapped boxes of Sytos Premium backup/recovery software for OS/2 by Arcada/Seagate ("Supports OS/2 Warp & Lan Server 4.0! Includes Graham Utilities Light!"). Have a genuine IBM box of "OS/2 Programming Tools & Information Version 1.2/1.3 Technical Upgrade 3.5'' Diskettes" with diskettes and manuals, mentions PM/2 and "C2, COBOL/2, FORTRAN/2 and Macro Assembler/2" bindings. Unboxed, I have the following developer bits in front of me: Collection 1: IBM Developer's Toolkit for OS/2 2.0 media kit on 3.5" floppy IBM C/C++ Tools/2 2.0 media kit on 3.5" floppy (these appear complete, but I cannot verify) - Dev Toolkit Getting Started guide - C/C++ Tools 2.0 Class Libraries Reference Summary - " " " UI Class Library User's Guide - " " " Programming Guide Collection 2: IBM Developer's Toolkit for OS/2 2.1 media kit on CD & 3.5" floppy still bagged IBM C/C++ FirstStep Tools 2.01 media kit on 3.5" floppy still bagged - Developer's Toolkit 2.1 Getting Started Guide - FirstStep Tools Programming Guide - " " " Debugger Introduction & Reference Summary If you're willing to cover shipping and a couple bucks for an item, let me know. First come, first served. I'll try shipping outside the US up until the paperwork becomes a pain, but will let you know and return funds if it falls through. For reference I'm in California, shipping >from ZIP code 94596 or I can arrange to meet in the East (SF) Bay. --Steve.
