After stating that I expected TSX Plus to be available generally to the collector community this week, I have had a number of folks request access to TSX plus via private FTP. Please be a bit patient and wait for me to post it to a new website I'm in the process of creating. I now have full agreement from S&H to generally release TSX Plus, COBOL, etc., to the collector community via a simple download. BTW: I have converted all of the original documentation, which was in HP print file format to PDFs for easier and more general use. Over time I will likely be able to release some of the utilities, etc. that S&H used internally with TSX plus. Some time ago S&H gave me all of their RL02 packs and a SMD drive with everything they had related to the PDP-11 version of TSX. (They have a current version of TSX for X86 systems which is NOT free and is NOT part of this release). Over time, there may be a project to scan the source listings and recreate TSX Plus source code. (The source listings are available on bitsavers.org (pdf/dec/pdp11/tsxPlus/listings/). Unfortunately, we are missing the MACRO definitions in the source listings. Some of us are working on that issue. (Note: All of the original PDP-11 source code was accidentally lost by S&H). I will also make available any software that other folks submit to me related to TSX on my website. Regards.

Xerox 6085 / daybreak microcode boot issues

by ian.finder＠gmail.com

So I picked up a 6085- When I try and boot it, it gets stuck on 0199, which indicates microcode is getting loaded. It never gets to 0200 or 0201, indicating a success or failure loading microcode. It just hangs. If I boot diagnostics instead, it tells me (in report codes) to replace the MPB first, followed by the IOP/io board. Well, I can't really replace the MPB because I don't have another, and I paid quite a bit for the machine. Anyone seen this issue before? Where should I start on diagnosing the CPU? Better yet, if someone has a 6085 MPB they are willing to sell, I would be eternally grateful. Cheers, - Ian Sent from my iPhone

Applikon Workstation?

by holm＠freibergnet.de

In the nineties I've workes as electronican and system administrator at the institue of geophyics at our local University of Mining and Technology here in Freiberg Germany. Some day I've got a call from Motorola in Munich, they wanted to get rid of some old computers and asked if we had some use for them, I've sayed yes. As far as I know we got 3 Computers, one was an 68000 Unix system from philips, some kind of Microcomputer development system for 8080 or 8085, I've got the system running but since there wasn't much software on the disk we had not much use for this thing. The disk was alsready dying and lived not that long. The next thing was a desktop VME System from Motorola, IMHO equipped with an 68010, some MMUs, an color Monitor ad Harddisk and Floppy.. it run some kind of VDOS (or so) .. or VME-DOS or soemthing.., I remember that we had some documentiation for it and I've reinstalled that VDOS.. but not much use for that thing also. The 3rd Computer was the most interestng one. That thing was labeled "Applikon Workstation" (as far as I remember, may be Applicon..). That was some kind of a microvax made by Schlumberger. It had an CPU that sat in a QBUS Backplane and a QBUS to UNIBUS Bridge. The CPU was only a double sized board (!), an Emulex UC07 conected the disk to the machine and so far as I remember there was some kind of graphics board on the unibus side. I've repaired the CPU Board by changing the RSA232 Drivers for the console and the beast came to live. I've fiddeled around with the TK50 Tapes containing VMS4.6 (if my memory not fails) but could'nt get warm with VMS... Installed NetBSD and failed. NetBSD was'nt booting from the SCSI Drives with the Emulex, someone sent me an UDA50 and I was able to install and boot NetBSD, but had to key in the loader at the chevron every time I had to boot.. I've sent the Emulex to Ragge for diagnostics and never got it back. The Machine ran for years as ftp server at the institute until I've pulled the plug. Have never seen a picture from that graphics board. I've leaved the University in 1989, the machine sat on the garret of the building to this time, I'm pretty sure it's long gone... Now I'm fiddeling with VAXen again and that old thing came to mind, looked with google but could'nt find a machine like this, not even a Microvax with a only doubles sized CPU Board like an KDF-11. The question now is...is someone knowing of a beast like this? Regards, Holm -- Technik Service u.

Xerox 820-II's available

by shaunhalstead＠gmail.com

Note: I've moved my ccmp stuff to my personal email account. I was formerly with Microfilm Services, Inc, which is now shuttered. I still have a pair of Xerox 820-II computers available, in Wichita, Ks. Two computers, with keyboards, and a single dual 8" floppy unit. I also have a few books and manuals for them, in original Xerox binders. Price: Make offer. PLEASE. After Labor Day weekend, they will probably be destroyed by the building owner. Shipping is in 4 large boxes from Wichita, Ks, and will not exactly be cheap. You can figure $100 minimum for shipping. Alternatively, I'm heading north along I-35 from Wichita, Ks to north Iowa Thursday 9/3 and Friday 9/4, if you wish to arrange a meeting along that route. (It must be at a location directly long I-35, such as a truck stop or other major, easily accessible location.) --Shaun

IBM 1620 / IBM 1401.

by geremin＠iprimus.com.au

Here in Australia, the Australian Computer Museum Society has an IBM 1401 - just the big CPU unit. We know of an IBM 1620 CPU unit in Computer Sciences at the University of NSW. I worked on a 1620 in the 1960s - and thought that it was 'magic'. Sadly, we don't have enough sponsors to put either on public display.

Announcing TCP/IP for RSX-11M-PLUS

by bqt＠softjar.se

I'm happy to announce a new release of TCP/IP for RSX-11M-PLUS. Since I'm broadening the scope of the announcement slightly, a more complete list of features is included, and not just what changed since last. For anyone who is currently running TCP/IP for RSX, I strongly encourage you to update to this latest version. Several improvements have gone in in the last couple of weeks. Most important change is that there now is telnet support, both client and server side. The TCP/IP for RSX that I've written is sometimes referred to as BQTCP/IP, just to make clear that it is a different product than Process Software's TCPWARE, or JSA's TCP/IP. BQTCP/IP is a rather feature rich TCP/IP implementation, which also comes with libraries for various high level languages. The API is not compatible, even at the source level, with Unix, but on the other hand, if people write some code, they will see that it is a very easy API to work with. The reasons for the incompatibilities are several, including both resource concerns and differences between how RSX works and Unix like operating systems. BQTCP/IP has tried to comply with all relevant RFCs, but I'm sure there are corners where it does not do things right. It also does not demand much resources. It do require RSX-11M-PLUS with split I/D space, and it has only been tested properly on RSX-11M-PLUS V4.6. It should work on any version 4 release of RSX-11M-PLUS, but there might be a couple of tweaks or fixes needed. BQTCP/IP is distributed in binary form, so very little compilation is required to get it up and running. However, pretty much all utilities do come with sources. The actual TCP/IP stack sources are not included. I do not have a good setup for distributing them in a sane way, and it has had a low priority on my list of things to do. But I do not mind distributing the sources as a general principle. All that said, BQTCP/IP current supports the following protocols: o Ethernet and loopback interfaces. o ARP. BQTCP/IP can use Ethernet in co-existance with DECnet, or standalone using the provided Unibus ethernet device driver. o IP. The largest IP packets supported are approximately 8KB. o ICMP. o UDP. The largest UDP packets supported are approximately 8KB. o TCP. The window is approximately 8KB in size, and TCP do manage out of order packets in an efficient way. BQTCP/IP supports the following applications: o DHCP. DHCP can be used to configure interface addresses, network masks, default gateways, DNS servers and NTP servers dynamically. o NTP. NTP can be used to set the local time. o TELNET. The TELNET server hooks in to the standard TT: terminal driver, and the number of terminals to create is configurable. The TELNET client can be used to connect to other systems. o FTP. The FTP server can serve all kind of files to other RSX systems, and can serve text and binary files to any system. The FTP client can retrieve RSX format files from RSX servers, and text, binary and block format files from any system. o TFTP. The TFTP server and client can be used for simpler file transfer operations. o RWHOD. RWHOD is a program that reports current users and uptime from RSX, for other systems to collect. o IRC. IRC is a program to communicate with other users around the world. o IRCBOT. IRCBOT is a small example robot program connecting to IRC and performing a service for IRC users. o PCL. PCL is a protocol for printing, used by HP (and other) printers over a network. The PCL implementation in BQTCP/IP appears as a print symbiont, which you can create a printer queue for. o WWW. WWW (or World Wide Web) is a service that can present hypertext information to clients. The WWW server in BQTCP/IP also supports CGI, which makes it possible to create dynamic content. o DNS. BQTCP/IP have DNS implemented as an ACP, that anyone can query to get translations between IP addresses and domain names. It also supports different users using different name servers, or private translations. o SINK. A standard TCP service. o ECHO. A standard TCP service. o DAYTIME. A standard TCP service. o QUOTD. A standard TCP service. o IDENTD. A standard TCP service. BQTCP/IP also have automatic IP spoof detection and prevention. Additional tools are IFCONFIG, PING, TRACEROUTE, NETSTAT as well as two new pages for RMD. High level language libraries exists for BASIC+2, PDP-11 C and FORTRAN-77. I'm sure I have forgotten a thing or three, but that's a fairly comprehensive list. The documentation is a weak point, but there is hopefully enough documentation to get people running, and I am happy to answer any questions, or give support if needed. BQTCP/IP is already running on the internet, and have been for a while. People who are curious to check it out can ether look at http://madame.update.uu.se/, or telnet to telnet://madame.update.uu.se and login as user GUEST with password GUEST, or use ftp against ftp://madame.update.uu.se. Anonymous ftp account exist. As usual, the distribution is available from: ftp://madame.update.uu.se/bqtcp.dsk ftp://madame.update.uu.se/bqtcp.tap ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk The .tap file is an RSX virtual tape. It is only possible to download and use if you are using FTP from anther RSX system and fetch the file. The .dsk files are virtual RL02 images that are useful both from within RSX as well as through emulators. The documentation is also available through ftp on Madame, or also at http://madame.update.uu.se/tcpipdoc Johnny

There is also a RAM chip siting with it too, don't have the specs at the moment. Includes 3 toner carts, all in various states of used. HP JetDirect external printer server - LPT, RJ-45, BNC Black IBM Model M type keyboard with trackpoint. PS/2 mechanical keyboard with AT connector. Shipping is unfortunately something I can't do at this time. Monetary donation would be nice, but I just need these to go. Some good lager or ale wouldn't be turned down either... :) -- --- Dave Woyciesjes --- CompTIA A+ Certified IT Tech - http://certification.comptia.org/ --- HDI Certified Support Center Analyst - http://www.ThinkHDI.com/ Registered Linux user number 464583 "Computers have lots of memory but no imagination."

Pre-VCFMW Sales and Free Stuff

by silent700＠gmail.com

It's a bit late but I may as well post my list of stuff I'd like to see go away this weekend. Small items can be delivered to you at VCF Midwest. Large items you'll have to pick up from my home or storage, both of which are <10 miles from the show, either during the week before or on Sunday evening after. (Or Monday mid-day if you're still in town.) The list at present: FREE (for pickup or +shipping) DEC TS05 9-track tape drive. Pertec interface, rail kit should be around here somewhere. Very clean, assumed working. DEC RL02 Drive. Once a home to mice, now a real "fixer-upper." Hey, they're tough drives. IBM MagStar MP 3570 tape library. Missing its tape cartridge but drive should be OK. SCSI interface. Heavy. FOR SALE Digital DECWriter III printing terminal. Repainted top, badge bent and poorly glued on. Was working when last tried. Cost is helping me get it out of the basement and another DECwriter down there to replace it. Digital DECWriter II printing terminal. Not sure about this one. Looks clean but untested. Will trade for something significantly smaller. I'll keep a running list here: http://chiclassiccomp.org/forsale.html If it's no longer on that list, it's gone.

ASR-33 differences

by cramcram＠gmail.com

Hi, I've finally gotten a hold of a restored ASR-33. One question I have concerns the paper tape reader. My recollection of using this TTY in the 70's was that the reader switch lever had 4 positions; on this tty there are 3. I know that for I have to add a reader control relay to interface to my PDP-8. So the question is: does having the 3 vs. 4 position reader lever affect using this with a PDP-8? Thanks, Marc

Larry Niven's Altair

by dave＠661.org

An Altair 8800 that once belonged to Larry Niven is up for auction. Larry Niven has long been a member of the Los Angeles Science Fantasy Society (www.lasfs.org). This group has existed since 1934 and was the starting point for many science fiction and fantasy authors. Larry Niven is one of them. This computer was purchased by him, but mainly used by his wife. In time, she got a newer computer and this one was made the club computer. It served in that capacity for many years until it too was replaced and was taken in by another club member who didn't want to see it parted out or thrown away. Fast-forward to 2008. I was contacted by that other club member to liquidate his collection. We went to Larry Niven's house whereupon he autographed this computer on the lid and the rear. I don't know if the drive unit was used by the Nivens with this computer, but it matches and is from the same collection. I also don't know where the client went. I haven't heard from him in years. You can see pictures in high resolution at https://www.flickr.com/photos/32548582 at N02/sets/72157653950476154/with/19938469936/ The auction is here (will be live July 25 at 3pm pacific) http://www.ebay.com/itm/231632418798 -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text.

Many Manuals - Also Boxes of Fan Fold Paper

by jhfinedp3k＠compsys.to

Since the topic of hard copy manuals is at least on a few minds, I thought I would mention that I have at least 20 feet of mostly DEC PDP-11 related manuals which will have to be tossed if a home can't be found. While I estimate that at least 90% of the DEC manuals are on bitsavers, some individuals may still wish to have hard copy manuals. Most of the manuals are either RT-11 software for many versions or manuals for specific hardware modules with regard to usage. There are no print sets. If you want a hard copy set of RT-11 Docs for V05.07 or TSX-Plus for V6.5, then you could reserve them for when I no longer will need them! Since I just turned 77, the wait might not be that long. I also have over 6 boxes of Fan Fold Paper (with sprocket holes), mostly 8 1/2" x 11", but maybe some 9 1/2" x 11" with tear off. The paper is available immediately. I will probably hold the manuals for at least 6 to 12 months. But I can't see anyone else bothering and it would all be tossed immediately. There is also PDP-11 Qbus hardware, but that is another matter. I am in Toronto, Ontario. Pickup ONLY since this stuff is much too heavy to ship! Jerome Fine

VMS 5.4 AUTHORIZE issues

by kylevowen＠gmail.com

Just picked up a very complete MicroVAX 3800. I have very little experience with VMS as this is my first VAX. Mostly a PDP-8 guy, I suppose. I'm running through the change password procedure, which I had seen mentioned previously on this list: SET VAXCLUSTER 0 SET /STARTUP OPA0: SET WRITESYSPARAMS 0 CONTINUE SET NOON SPAWN /NOWAIT SYS$SYSTEM:STARTUP.COM SET DEFAULT SYS$SYSTEM RUN AUTHORIZE At this point, I get this: %DCL-W-ACTIMAGE, error activating image SECURESHRP -CLI-E-IMGNAME, image file R7CY2A$DIA0:[SYS0.SYSCOMMON.][SYSLIB]SECURESHRP.EXE;2 -SYSTEM-F-PROTINSTALL, protected images must be installed $ What would I need to do to correct it to login? The eventual goal is to get this online, which should be feasible. I have an AUI-to-10Base-T adapter (several, actually). I think that'll be a little while away for now, though. Here are some pictures: http://imgur.com/a/WYGra Thanks, Kyle

Origin of "second system effect" before 1975?

by tshoppa＠wmata.com

I know of two publications in 1975 that used the term "second system effect" or "second-systemitis". 1: Brooks' _Mythical Man-Month_. 2: Bell's and Streeker's "What We Learned From the PDP-11". Does anyone know of earlier usage of this term or earlier names for this effect, possibly outside of computers? Tim.

John @ CPUShack?

by drlegendre＠gmail.com

Wonder if anyone here has ever dealt with John Culver, who works from the address john at cpushack.com? He operates a site at the same URL. Among other things, he's a buyer, seller & collector of vintage CPUs, and associated chips. I've done several deals with him, with goods & money moving both directions at various times, and have nothing but good memories. In my experience, the guy is a real mensch, so I wanted to give him a plug here - May I suggest that anyone who might be looking for a specific vintage chip give him a holler and see what he can turn up? IMO, you could do a whole heck of a lot worse! -Bill

RT-11 on a PDP-11/10

by bqt＠softjar.se

Hi all. Update have an 11/10, that was recently powered on again for the first time in I don't know when. After some fiddling with the RX01 disks, we put an RL11 and an RL02 on it. Lots of space, I know. :-) Also, we have RT-11 running on it. And for fun, we wanted to run the original Tetris. But here is the catch - Tetris is using some instructions that the 11/10 don't have. (I would guess EIS stuff.) Do anyone know if there is some software emulation of these instructions that can be added to RT-11 in order to be able to run such programs? RT-11 V5.5 by the way, if anyone wants to know. And no, I am not sitting by the machine, or trying to play with it personally. It's other people at Update. But an 11/10 is cute. And we did boot the RL02 on Magica (11/70) to check that there is nothing wrong with the binary, and it runs fine on that large machine.

ColourPET

by echristopherson＠gmail.com

I just noticed the September 2015 issue of Nuts & Volts has, right on its cover, a project to outfit a Commodore PET with color (digital RGBI) output. It requires a PET with the Universal Dynamic PET motherboard, the one that could be switched between 40 and 80 columns via jumpers; the actual output is only in 40 because of memory limitations. The specific project in the magazine allows four 16 foreground and 16 background colors per pixel, but it says the author has also made it output 8-bit analog RGB foregrounds with one fixed background color. -- Eric Christopherson

by ian.finder＠gmail.com

Hey all- I've always wondered about this. Their website hasn't seen a proper update in years, and it looks like they have a lot of choice hardware donated to them that they may not be maintaining... Is it open to the public? Are people actively volunteering there to make sure this stuff is shown some love and not falling into disrepair? Keeping leaky batteries, capacitors, rust at bay, and doing repairs? Imaging disks? They have some very worthwhile examples of machines but I haven't seen much >from them as an organization in years! I'm sure lots of people would be willing to help if they are under-resourced. Thanks, - Ian -- Ian Finder ian.finder at gmail.com

Osborne O1 Keyboard issues

by drlegendre＠gmail.com

Howdy gents, Working away on the recently acquired Osborne 1. Seems there's something wrong with the KB - and if I didn't know better, I'd say it's a case of shorted contacts. The KB connector is 24 pins, double row header like a short floppy or IDE header. On the KB side, there are two "shorted" groups of pins. Group one is 2X shortred pins, group two is 5X shorted pins. Thing is, this KB is not really built to be serviced, best as I can tell. The switch matrix is made of two layered flexible circuits, and the key assys are 'riveted' in place, by melting over the plastic pins. So I see no way to disassemble it and give it a clean.. and then, even so. With such limited access, I don't see many avenues other than flushing with solvent(s) and hoping for the best. What's to be done? Is this one.. done already?

Side issue Bevatron PDP-8 Classic & teletype control? and great print/scan cheap

by COURYHOUSE＠aol.com

Any Northern Calif folk (current or Ex) that might have been around the BEVATRON - Ok this thing had pdp-8 computers ( the classic first model rack mounted) and teletypes hooked to it I am finding very little info on it... Just scanning stuff on Crocker's Cracker (the 60 incher) here tonight and putting together blueprints. if you want a from the store solution try the hp 7612 scans and prints in excess of 11x17 on sale less then 200 bucks! I highly recommend the Microsoft labs stitcher program. I have had some scans with some pretty crappy alignment and I made one giant beauty of a blueprint. The 7612 also prints beautiful 11x17 color prints to go in displays here for the museum.

Front Panel Progress - 8/e (type A & B) e/f and 8/m Update

by rodsmallwood52＠btinternet.com

Hi Guys! I now have the (hopefully) final artwork for all four PDP-8 front panel variations. I have made up a display file. The file shows the combined black positive master for white lines, white text and logos for all four designs. There can be up to five layers and hence screens for each panel. The file is in .svg format because I use Inkscape to do most of the work. Let me know who would like a copy Regards Rod

9-Track 1/2" Tape Drive Recommendations?

by cctalk＠fahimi.net

Hello All, Recently I came across a complete Pertec interface (card, manual, software, and, cables) thanks to list-member Shaun. Of course what is the point of having an interface if you have nothing to interface it to! So I've been looking at, and learning a bit, about 1/2" tape drives. I've also looked into acquiring one. But before going down this path I wanted to see what pitfalls, warning signs, etc. I should be on the lookout for. I am looking for a unit mostly to experience the tech and to play around with. I do not plan on recovering data from any particular system or format. However, it would be nice if I could setup a system that actually worked for backups of say an IBM AT for demonstration purposes. Having read some old InfoWorld and PC Mag articles I can see there were a number of tape drive manufacturers well into the early 90s. Based on the reviews the Cipher and Qualstar units seem to be well suited for my purposes. Any other brand/models I should keep an eye out for. I know IBM also had some 1/2" 9 track tape drives (9437 and 9438) but neither was a Pertec interface from what I have gleaned. The 9347 used a proprietary interface and the 9348 used HVD SCSI which is atypical. There was apparently a 9348-012 model which used narrow SCSI so should interface with a standard Adaptec card. However, I have not been able to determine if it used standard SCSI commands and could be accessed say with a tape backup program under Windows 9x/NT or DOS. Of course the biggest problem is finding one locally in the LA area. Unfortunately my only resource is eBay and prices there are definitely not hobbyist friendly (not to mention shipping). If anyone has a line on a working drive in the LA area (to save on S&H and avoid the dangers of shipping) or a reasonably priced one elsewhere I'd appreciate it. TIA for any help.

(OT?) Copyright and IP

by thrashbarg＠kaput.homeunix.org

Hi List, This relates to the ongoing discussion about vintage computer software copyright. A year or so ago I did some Beta videotape backups for the Australian Computer Society. They're of keynote speeches at the 10th Australian Computer Conference in 1983. One that I'd like to mention is by Tania Amochev from (then) Control Data Corporation, titled Information Services of the Future. In it, things we now call data mining and Google AdSense are discussed, and the potential of data services in general (this is in 1983). One thing that struck me was the contrast between traditional copyright of material items, and how such ideas don't apply very well to non-material information. I was left with the impression that the idea of "Intellectual Property" is in some ways an attempt to force information to be treated like materials, which is an easy way to put a value information, but also allows it to be hoarded. This goes directly against how information behaves, which is to flow freely. This free-flow of information allows more information to be derived or generated, enhancing productivity and overall knowledge. To quote: "Information is diffusive - it leaks. The more it leaks, the more of it there is. Information is aggressive, even imperialistic. It simply breaks out of its unnatural bonds, the bonds of secrecy in which 'thing minded' people try to lock it. So secrecy, property rights, confidentiality, all enshrined in Western thought and law, are not particularly effective restraints on information." This is not a cry to abolish copyright and intellectual property laws, but to highlight some of the inadequacies of the thought process behind these laws when dealing with high speed, global information. Does anyone have any thoughts? If there was a massive shift in the fundamental philosophy of how information should be valued, where would you like that shift to go? For example, is there a way to pay programmers and similar professions by the quality of their work, rather than just the number of lines of code they write. How do you measure the quality of information? I'll see if I can get permission to have the six keynote addresses put online, because they're all fascinating. Cheers, Alexis. P.S., if this is way off topic, my apologies.

That is what the Air and Space Museum has done for a while - a very thin wax coat covers the original, untouched finish, and a new paint job is applied onto the wax. Apparently it is easy to strip off, thus a reversible portion of a restoration, but I think the paint is not durable at all (which is why you should not touch things in museums unless given permission). I am not a fan of the Retrobrite process, although I have never tried it out. In my mind it just seems wrong. -- Will

Hi, I've managed to relaocate the pagefile.sys of my VMS7.3 to the secondary disk disk1$dia1 because of space considerations of the first disk (380MB total, free blocks 228672 now). I've seen complaints of the system that the disk wasn't properly dismounted after each reboot and would be rebuild. A hint from my friend Vaxman was, to mount the disk with the option /NOREBUILD in SYPAGSWPFILES.COM so it looks like this now: $ MOUNT/SYSTEM/NOASSIST/NOREBUILD DISK1$DIA1: DATA1 $ RUN SYS$SYSTEM:SYSGEN INSTALL DISK1$DIA1:[SYSEXE]PAGEFILE1.SYS/PAGEFILE EXIT $ EXIT Is there an other way to properly dismount the drive at the shutdown? My home directory lives on the 2nd disk too..and I think /NOREBUILD supresses the warning message, but not the problem at all.. Regards, Holm -- Technik Service u.

Sign magnitude, one's complement, two's complement

by spc＠conman.org

For my own morbid curiosity, and because it came up on another mailing list I'm on [1], what machines commercially avaialble were sign magnitude and one's complement? Every machine I've encountered was two's complement (okay, IEEE 754 [2] is a sign magnitude format but I'm talking about integer implementations here, not floating point). I've only found reference to one sign magnitude computer (the IBM 7090, release in 1959) and a few one's complement machines (mostly the PDP series from DEC). Where there others? And honestly, are there any machines that use anything other than two's complement today? -spc [1] http://lua-users.org/lists/lua-l/2015-08/msg00386.html [2] AKA floating point.

Indianapolis: More classic computing equipment than I can shake a stick at.

by maxxtw＠gmail.com

Anyone who's passing through, or lives near Indianapolis, feel free to give me a shout to set up a time to peruse what I have. I have amassed enough machines to take on their own gravitational pull. Most are in various states of disrepair, in need of attention, but quite a few still work or don't need much work to be functional. A number of machines I intend on keeping for their "neat" factor (like an Olivetti M20) but might be persuaded to part with. Apple (bunch of IIc's, IIe's, IIgs's) Macintosh (40 or so compact Macs - 512, Plus, SE, 'splodey-battery-SE/30's -, a big 'ol stack of 68k and PPC desktops, PowerBooks, a stack of DuoDock II's) Kaypro (maybe 6?) Osborne Compaq Portables (luggable and plasma) Epson QX-10 (2 machines, 1 monitor, pretty certain I have the Valdocs disk somewhere) IBM (5150's, 5160's, and a 5170 with box, and a few monitors) Wang (PC S1-2 with keyboard/monitor(s)) Franklin 8000 with keyboard A few 386/486 machines ADM 3A terminal (doesn't power on, but it's cute) Amiga 2000HD (boots, but I don't have a keyboard or mouse, and the floppy drives continuously seek) Amiga 500 (untested, no power supply) C64's (definitely for parts!) and some drives Tandy 1000 EX (untested) NeXT 21" Color Monitor (too huge and heavy for me to keep, I'll be happy with a VGA converter when I find one) And probably a few other things I'm forgetting about. Price-wise, basically make me an offer. Scrap metal prices are fine with me for a lot of machines so long as they're not actually getting scrapped (hence the post here!). If you're looking for something specific, let me know and I'll see what I have. Thanks! Kind regards, -Maxx
