Hello!

by scaron＠umich.edu

Hi everyone, I just wanted to send a brief little message out to (re?)introduce myself to the group... I was one of the earlier contributors to the original classiccmp list maybe 15 years ago but I drifted away from the list and computer collecting in general ca. 2001-2002 as I got busier with my university studies and I had accomplished most of my collecting goals. One engineering degree, a successful IT career and a starter home later... I've put down some roots, got a house of my own... perfect time to gather up all my big heavy things and bring them home :) I figured it would be fun to chat with some other folks who are still in the hobby. I left my collection in the hands of some folks that I shouldn't have and it suffered some losses over the years... maybe I can do some wheeling and dealing here to recover some of what I'm missing? My main focus in collecting is mostly old minis and "workstation" class hardware. I like to play with SGI, NeXT, DEC Alpha, DEC VAX, DEC PDP, Motorola MVME boards of all types, 68k Macs and to a lesser extent, Sun SPARC equipment. I'm mostly looking to pick up a few Q-bus and Unibus boards... I'm trying to finish up a complete board set for a KA650-based Qbus VAX (anyone got a few 16 MB MS650s or a Q-bus SCSI card at a reasonable price?), and I need a RX01/02 controller for my PDP-11/34a. I'd love another DEC BA23 at some point to mound said complete KA650-based boardset... I used to have three very nice BA23s in my inventory... one perfectly filled out uVAX III... all were lost :( I'm mostly looking to trade or sell some miscellaneous parts for SGI, NeXT, Apple and maybe to a lesser extent, DEC. Excited to be back! Best, Sean

Pile of Mac G4s

by nospam212-cctalk＠yahoo.com

I have about 12 various models of Mac G4 towers. These were used for audio recording and art production and were being tossed. Before I spend the time to see what all is in each machine and their conditions I wanted to see if there was any interest in the systems. If not I won't bother with them as I have samples in my own collection already. Be aware they are rather heavy for shipping. Systems are located in Houston, TX. David www.trailingedge.com

MFM reader emulator

by djg＠pdp8online.com

I have now completed layouts for a PCB for the MFM disk reader and emulator that I mentioned back in February. I will add to my order boards for others who are interested. I am not planning to kit or assemble. You will have to do that yourself. For information on the board see http://www.pdp8online.com/mfm/ Email me if you have any comments or questions. I did two different layouts, one all through hole and one with 3 surface mount chips that has some minor advantages. See link above for discussion. I plan to only order one version. If you are interested in a PCB's email me with 1) How many you wish 2) If you prefer or are only interested in the through hole or surface mount version. Unless you state I don't need to I will email you back when I get ready to order with the final price for confirmation that you still wish them. I plan to collect money when I am ready to ship them. The cost to make one is: Beaglebone $55 (they increased the flash by 2G and the price by $10) PCB $30 (depends significantly on quantity) Parts $54. Can reduce by $24 if you don't need the holdup capacitors. See the BOM for parts and prices. See description of board for what the holdup capacitors do. TBD Shipping Unless only a few are desired I will likely buy a couple cheap PCB's without the hard gold on the edge fingers to verify I haven't made a serious error. This will delay final order. I tried to get my cat to peer review but it only shredded the paper.

Catch and Halt Fire - Drama set in early days of personal computing

by sellam＠vintagetech.com

I watched about 3 minutes. Pure garbage. Halt and Catch Fire is not a real computer instruction that caused a race condition that made the computer stop working. I imagine a bunch of teenagers are scouring Intel technical manuals looking for the Code 2 Duo equivalent of HCF. No one looked, acted, or talked like that back in the early 1980s (I remember, I was there). Especially not IBM sales people. If you could find a chick anywhere that looked 1/4 as cute as the chick in the opening scene and who knew as much about computers, you were either in the future, watching a bad 2014 television drama, or you were someplace private by yourself with your pants down lost in your imagination. I'm sure I could come up with more criticisms if I could deaden my senses enough without taking out critical life functions to watch the rest. Unfortunately, this program was designed for the braindead, technically illiterate cultural group that comprises television watchers generally. Whoever wrote this knows a computer collector. However, based on the level of comprehension of the subject matter that gets incorporated into the script, the writer probably only likes the computer collector in as much as they can get fodder for their crappy TV scripts. If any Hollywood people are reading this and want to make a good historical computer based drama or movie (it's been all downhill since War Games), you know how to contact me. -- Sellam ibn Abraham VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap.

Catch and Halt Fire - Drama set in early days of personal

by kurt＠hamm.me

I was there in the late 70s and early 80s. I absolutely enjoyed the first episode and looked at it like the beginnings of Compaq. The legal restrictions on reverse engineering were close enough. The sets and wardrobe were obviously well thought out and seemed familiar to me. I enjoyed them immensely. I loved seeing those old computers. This is a great opportunity to engage an audience outside of our close knit community. So many people lived through the time if not as profoundly as we did. How can this show be a bad thing for us? Sellam continues to be a prick about anything related to what he feels is his claim to computer history. I see his post as fishing for some piece of the action. It included a plea for the producers to call him and smacked of sour grapes for not being consulted. For my part, I am disgusted by anyone who would make a value judgement about physical appearance especially related to technical competency. It is a completely subjective evaluation and has no place in this discussion. We should relax and enjoy the first major impetus for remembering and collecting this past. IMHO. Kurt

Ersatz-11 V7.1

by wilson＠dbit.com

V7.1 of Ersatz-11 is done. New features include: - DMP11/DMV11 network ports. - DDCMP over TCP and UDP (as well as serial lines). - Kermit client for transferring files in and out of the PDP-11 over any emulated serial line (KERMIT command and KERMIT: pseudo-driver). - "MOUNT ddcu: BAD: /LIST:badblks.txt ..." adds fake bad blocks (from a list in a file) to any disk (for testing PDP-11 utilities). - "MOUNT ddcu: ... {/NOPAD | /PAD:NULL | /PAD:RAM}" selects how to handle emulating disks with an image file (or physical drive) that's smaller than the drive being emulated. (/PAD:RAM is currently an experimental feature and may have bugs -- it's intended for systems that use the tail end of the drive as swap space.) - DPDISK: and DPTAPE: (BOTH UNSUPPORTED) set up dual-ported disks and tapes. Any disk or tape type can be mounted on one of these pseudo-devices, after which units 0 and 1 of the pseudo-device represent the two ports which may in turn each be mounted on different PDP-11 controllers, presumably on different processors of a multi-processor system. Unsupported, as I said, just like all mP features. - "SET TTu: DL11A" (needed by DOS/BATCH for TT0:). - "SET PCLOG n" enlarges the number of logged PC values that can be shown with SHOW PCLOG. - New native "SYS" utilities for Linux, OS/2, and Windows, for making disks (or flash drives) boot the stand-alone version of E11. The Linux and Windows versions try to notice if a drive (e.g. USB flash card that came pre-partitioned) hasn't been made "active" and/or is missing the MBR bootstrap, and fixes it (may require privs). If anyone can please tell me what sys calls in OS/2 will find out which physical drive owns a FAT volume given the drive letter, I'd appreciate it! - The stand-alone version's bootstrap supports USB drives (including flash). Also there's a bootable CD, but since there's currently no ATAPI dev driver or ISO9660 FS driver, it can't install E11 onto a hard drive, and it requires a FAT volume to hold .DSK files etc. So it's more of a proof of concept than something useful (but it's an easy way to try out the stand-alone version of E11). Bug fixes and tweaks as usual (sorry about that .TAP seeking thing in V7.0!). As usual, the Demo version can be downloaded from: http://www.dbit.com/demo.html Updates have been mailed to commercial users with current subscriptions. John Wilson D Bit

Listing of 60s mainframes/minis with CRT displays?

by dmonnens＠gmail.com

Thank you to everyone who has responded so far. Let me clarify a little - Marty and I are looking for a list of computers >from about 1971 and earlier (1977 at the latest, but the real focus is on the 1960s) that had the capability of playing Spacewar. We've had reports of a few different machines running it, but obviously there are going to be a lot of gaps in oral history. Having a list of machines with displays (CRT, vector, or other) would help identify where some of those gaps might be. Here are all the machines we've had reports of Spacewar on them: 1. PDP-1 2. PDP-4 3. PDP-6 4. PDP-7 5. PDP-8 (probably text-based version) 6. PDP-10 7. PDP-11 8. LINC-8 9. DEC-10 10. HP59825 desktop calculator 11. 544 ARTW/Trajectory Division 12. PLATO 13. DDP-224 14. IBM System/360 (IBM 2250 Model 1 display) or 2250-4 (a 2250/1130 Model 4) 15. CDC-3100 16. Data General NOVA 17. IMLAC PDS-1 18. Virtual Machine Facility/370 (VM/370) Note some of these have multiple versions created in different locations independently. 1972 is a key date because that's when PLATO went on the ARPANET, and software could be more widely distributed. This was also the first year that Spacewar was written for a home computer in BYTE Magazine. 1977 was the release of the arcade version and publication of a version for the Altair 8080. Want to clarify that we're not looking for home computer releases, unless maybe you have examples earlier than 1977. > On Mon, May 26, 2014 at 05:08:41PM +0100, Dave wrote: > > > > If you are talking 1960's I think the real answer is "not much".

A small collection of PDP8's and PDP11's in Adelaide

by bob.willson＠adelaide.edu.au

Hi All, I have a small collection of PDP8's and PDP11's in Adelaide South Australia. The group is made up of a PDP 8/L, 2 X PDP 8/E's, 2 X PDP 8/F's, a PDP 11/10, a PDP 11/20, and a PDP 11/44. The 8/L is bare but the rest have RK05's except the 11/44 and an 8/F with floppies. Their purchase was arranged by me in the 1970's and they have been given to me by the School of Psychology at the University of Adelaide. They have been stored in an air conditioned environment since purchase. A couple of years ago when I began to think about disposing of this equipment my ambitions were quite small and I thought I would just put them up on ebay and see what happened. Since then I have looked at the computers more closely and with the assistance of the former engineer involved at the time we have put 3 of the computers back in operation. As far was we can tell the PDP 8/L runs trivial programs, the PDP 8/F with floppies runs OS/8, and one of the PDP 8/E's runs the processor OK but the Plessey disk (RK05 look alike) didn't boot (but we'll fix that). Currently the former engineer is a lecturer in Computer Science and has expressed an interest in one of the PDP8's in a running state as an exhibit in his office. I may keep the 11/44 but we need to dispose of the rest, eventually, and in a running state. We think we will put up the 8/L for sale first. The package consists of the 4K PDP 8/L, a BA08 Expansion Box containing a KV8/L controller, a Tektronix 611 display and a 1250VA DEC Autotransformer to run the 115V 8/L system in the 230V land of Australia, and associated documentation. The PDP 8/L powers up and the fans and power supplies check out. Memory addresses can be examined by auto incrementing through memory. Data can be deposited in memory. Trivial programs seem to execute and switches seem to perform their intended function (allowing for a little intermittent functioning after 30 years stasis). I believe both the PDP 8/L and the KV8/L controller can be functioning systems. I know there is an international market for this equipment but is there anyone or any group in this country (Australia) that we might give advance notice of an intention to sell this sort computing equipment? Let me know if you are interested or want further information (bob.willson at adelaide.edu.au). Regards, Bob. -- Bob Willson Phone : +61 08 8272 3659 School of Psychology Fax : +61 08 8303 3770 University of Adelaide Email : bob.willson at adelaide.edu.au Adelaide, South Australia 5005 CRICOS: 00123M

Basic Four 410 / Microdata 1600

by ad＠ardiehl.de

Hi, i recently got a MAI Basic Four 210 from the Netherlands. The CPU now powers up, have not yet tried the 14" Piram harddisk. I would like to know if the CPU is working. It seems to be based on a microdata 1600 but equiped with dram and cmos ROMs. The machine has switches were it can be set to boot standard/alternate >from disk, tape or from a serial terminal. Since the tape drive has a capstan roller transformed to liquid and i have not yet tested the disk i would like to know how to boot from a terminal. I have not yet read the microcode proms nor have i checked if they are soldered or on sockets. Does someone out there have access to the cpu manuals that are stated in the service manual ? 1300 CPU Technical Manual, Document No. SM 1200 M1300 Series CPU Organisation and Description Reference Manual Pictures from the machine are here: http://www.ardiehl.de/basicfour/mai210/pics/small/ and the manuals are on bitsavers in pdf/mai, the service manual also contains the cpu schematics, the ones for the tape controller and the disk controller are included in the tape / disk service manuals. What do you think are the chances to get the disk up and running. (since i have no tapes of other software) All seems to be stored dry, no rust, nor a lot of dirt in the machine. Seemd to be powered on the last time more than 15 years ago. ---------------- Gr?sse Armin Diehl ad at ardiehl.de

Listing of 60s mainframes/minis with CRT displays?

by wgungfu＠gmail.com

Hey guys, we're on the next phase of our paper we're presenting at a conference soon and are hoping to collect a listing of 1960s era mainframes and minis that had CRT displays available for them. We're obviously already aware of the various DEC models released in the 60s that had them, but we're looking for other brands now. If you guys would be so kind to help us out (since we're in a bit of a time crunch) and share the following, it would be awesome!

Tools in the Computer Operator's Desk Drawer

by nf6x＠nf6x.net

I have this vague memory that back in the day, any well-equipped computer operator would have a tool in the desk drawer which trims the end of a mangled magtape to a nice, neat curve. Do I actually remember that, or did I make it up? As I get older, my imagination is getting better than my memory, and it's getting a lot easier to vividly remember things that never happened. If such a tool exists, I want one! I recall another little tool (and I think I still have one somewhere) that was a give-away from the Sun User's Group. It was a little pocket-clip screwdriver with a flat blade on one end, a hex key for VME card mounting screws on the other, and "SUGtool" or something like that marked on the side. One of our printers in the computer room that I worked in at UCI in the late 1980s had a tool sitting about for punching the carriage control tapes for one of our old line printers. We had separate printer queues for letter sized and wide format paper, both pointing at the same printer. One of the operator's jobs was to frequently stop one queue, change the control tape loop and the paper in the printer, then enable the other queue. Write rings were littered all over the place, naturally. And then there was the suction-cup tool for lifting the raised floor tiles. What else might be found in the operator's desk drawer or sitting around the computer room? -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/

DEC RC25 repair

by aswood＠t-online.de

Hello all, I got some RC25 drives and a big pile of cartridges. Beside of only some few drives most of them are showing the typical symptoms of these drives, the seal between the tubing on the back side of the drive has gone to goo. There is a now a gap and just powering on the drives would result in a head crash without doubt. Since the drives in question had been powered down in working conditions long ago, the gooeing occurred later on, so there could be a chance to bring back them into life if there would be a solution to fix this issue. Were there any successful attempts by members of this list to solve this issue? Andreas

Tools in the computer operators desk

by wmachacek＠q.com

I still have my Sort Verifier tool. A long slim piece of metal for verifying that all the cards in a card deck had a hole punched in the same place on all the cards. I also have several IBM connectors for the 407 Accounting Machines that allowed a signal from one connection to be sent to two different connections. I have both the grey and orange connectors. The IBM name is on the connectors, but there is no name or markings on the Sort Tool. I should have saved a couple of 407 connection wires (there were many different sizes and colors), but I didn't..

60s Mainframe/Mini Disk File Systems

by t.gardner＠computer.org

IBM famously introduced its CKD disk file format in the 60s; did anyone else (other than IBMs clones including RCA) support such a disk format? Specifically a disk format with a block (record in IBM terms) having a variable length key field (including 0 length) and a variable length data field. To the best of my knowledge everyone else used a fixed block (sector to most) size on a disk volume but my knowledge of most of the BUNCH is limited. Tom

How to create a CF boot DOS

Basic Four 410 / Microdata 1600

by ad＠ardiehl.de

Hi, i recently got a MAI Basic Four 210 from the Netherlands. The CPU now powers up, have not yet tried the 14" Piram harddisk. I would like to know if the CPU is working. It seems to be based on a microdata 1600 but equiped with dram and cmos ROMs. The machine has switches were it can be set to boot standard/alternate >from disk, tape or from a serial terminal. Since the tape drive has a capstan roller transformed to liquid and i have not yet tested the disk i would like to know how to boot from a terminal. I have not yet read the microcode proms nor have i checked if they are soldered or on sockets. Does someone out there have access to the cpu manuals that are stated in the service manual ? 1300 CPU Technical Manual, Document No. SM 1200 M1300 Series CPU Organisation and Description Reference Manual Pictures from the machine are here: http://www.ardiehl.de/basicfour/mai210/pics/small/ and the manuals are on bitsavers in pdf/mai, the service manual also contains the cpu schematics, the ones for the tape controller and the disk controller are included in the tape / disk service manuals. What do you think are the chances to get the disk up and running. (since i have no tapes of other software) All seems to be stored dry, no rust, nor a lot of dirt in the machine. Seemd to be powered on the last time more than 15 years ago. ---------------- Gr?sse Armin Diehl ad at ardiehl.de -- ---------------- Gr?sse Armin Diehl ad at ardiehl.de

Macintosh Basic?

by rob＠bitscience.ca

Does anyone have a copy of the original ?Macintosh Basic? that they?d be willing to share? What I?m looking for is the version of Basic that was written by Donn Denman et al. at Apple in 1985 or so ? have a look at http://www.folklore.org/StoryView.py?story=MacBasic.txt if you don't know the story. Beta copies were widely available in the user-group community at the time, but Apple ?cancelled" the project before it officially shipped; I recall having a copy myself in early 1985, but I can?t find the disk. I?ve done some searching online, but it appears not to be available in the usual places. Feel free to contact me off-list. Thanks very much, Rob Ferguson rob at bitscience.ca

DataGeneral Model 10,20,30

by supervinx＠libero.it

Hi! I acquired a DataGeneral. The label on the back says Model 10,20,30. I powered it up and noticed white smoke. It looks like a RIFA capacitor burn, since the fan kept spinning and the smell was the RIFA one. Do you have a link on some PDF infos? I'd tear it apart without breaking something. I checked the cards and they looks OK, so the HD, floppy drive and tape. The two PSU modules are tied to something on the back. Plastics seem a bit fragile, so I'm acting carefully :) Thanks!

Morse wrote much of the unit-record IO drivers for VMS, and then maintained them for some time. They must have started the VMS project in about 1975 to get the machine ready to sell in 1978. I know Kathleen was there for quite a while before that, I THINK she was on the cover of one of the minicomputer handbooks from DEC. I spent quite some time reading her code when hacking printer drivers and such. If you searched the VMS source code for her initials "KDM" I'm sure they appeared many thousands of times on patch ID lines. Jon

Catch and Halt Fire - Drama set in early days of personal computing

I see this is to be broadcast in the U.S. soon. http://www.stuff.co.nz/technology/digital-living/60069626/pc-tv-series-to-d… In fact if you live in the U.S. you can see the first episode apparently (I can't here in NZ...it's blocked). http://blogs.amctv.com/halt-and-catch-fire/2014/05/watch-a-sneak-preview-of… Anyway, I thought some of this list might not be aware of it and might find it interesting. Will it inspire more people to take a look at earlier personal computing history I wonder? Terry (Tez)

Question about SIMH .TAP files

by rickb＠bensene.com

The username field in the archive is of the form used on CDC Cyber computers running NOS or KRONOS. University of Illinois was big on CDC machines. I bet it is some kind of archive format used on CDC machines to create tapes that could be interchanged with other types of systems, e.g. IBM. I wish I could remember more detail from my Cyber operator days, as I do vaguely remember that there was a utility that we ran to create takes in a format that the big IBM systems on the business side of the company (Tektronix) could read. Please excuse top posting, my phone won't let me post any other way.

(PDP-8) RK05 problems. Anyone have the source to RKUTIL?

by cramcram＠gmail.com

My RK05's are acting up again. They first acted like this when I was bringing them up after a 30 year nap. The symptom then was that one of the Maindecs for disk testing would complain that it couldn't write because a CE disk was in the drive! (Which brings up the quesiton: Why would it think that? Is there a wire on the disk interface bus that is pulled down when a either a CE disk (how??) or else the disk alignment suitcase is plugged in?) Anyway, now that I can run RKUTIL I have a new problem that just happened this weekend. I can no longer select option 4 (read/write test). It simply reprints the prompt, no error message at all! I assume this is the CE present problem rearing it's ugly head again. RKTUTIL worked fine up until this weekend. Anyway, I'd like to look at the RKUTIL source but can't find it anywhere. Does anyone have a pointer to this? Also, if anyone knows what triggers the CE present condition I'd like to know about that too. Thanks, Marc

We had a very attractive young woman who did programming on the business stuff, and we insensitive males referred to her (out of her earshot) as "software". She dressed well, she was sweet and friendly (and obviously, tolerant!) and she could code. Back further, in the 1970s there was a young woman in my FORTRAN class I dated briefly. She was also on the high school swim team, and I started attending meets. :-) Yes, things were more gender-imbalanced than they are today, but making any gender-based assumptions (appearance, fashion sense, etc.) about the women who *were* involved in the industry is not particularly useful, meaningful or accurate.

Question about SIMH .TAP files

by cclist＠sydex.com

I've been reading the SIMH TAP file specification and there's something that's not clear to me. Perhaps someone can volunteer their knowledge. I've got a tape where about half the records (blocks) are an odd number of bytes long. The SIMH document says that a block is padded to an even number of bytes in this case. However, it doesn't say if the record length (32-bit) word is adjusted to reflect this--or if the byte count is rounded up to the nearest even byte. It seems to me that the former would be the way to go, but I'm not sure. If the latter course is taken, the information that the block is an odd number of bytes long is gone. Does anyone know for certain? Thanks, Chuck

> Interesting Minis with displays... There are a lot listed in the Communications of the ACM journals. Taking a random May 1967.....NCR 315 family, SDS (Sigma 7,5), Burroughs 500, Univac 1108...at least to get an idea of what systems look like so you can hunt down the terminal/vector/display types. Don't forget plotters and terminal printers. What percent used these as the primary display? Or is that not what you want? Bill

The LINC, LINC-8 and PDP-12 at least had character generators that would draw a 2 x 6 grid of dots from a 12-bit word. Two of those grids would draw a 4x6 dot matrix character on the screen. So, a character could be drawn with a small number of instructions. Jon

Listing of 60s mainframes/minis with CRT displays?

by elson＠pico-systems.com

From: Martin Goldberg<wgungfu at gmail.com> Hey guys, we're on the next phase of our paper we're presenting at a conference soon and are hoping to collect a listing of 1960s era mainframes and minis that had CRT displays available for them. We're obviously already aware of the various DEC models released in the 60s that had them, but we're looking for other brands now. Don't forget the LINC, a major feature was the character display. It could also display limited graphics (due to CPU speed) and waveforms. The early LINCs were made with DEC parts, but were assembled by grad students at a summer session. We had a PDP-5 which had a very similar system on it that was apparently made by DEC, or at least it seemed to be factory-made. Jon
