Urr, I'm not up to making them! I was really hoping for the plug-in replacement ones in white... They used to make replacements in red (we replaced the bulbs in our -11/45 with them, BITD), so I was hoping. Anyone know of a contemporary source for LED replacements for front panel bulbs?

Heh. I had decided that the easiest clean and long-lived fix was to just to do it right, using the long division routine used in the V7 C compiler runtime: http://minnie.tuhs.org/cgi-bin/utree.pl?file=V7/usr/src/libc/crt/ldiv.s and I vaguely recalled reading a DMR story that talked about that, so just for amusement I decided to re-read it, and looked it up: https://www.bell-labs.com/usr/dmr/www/odd.html (the section "Comments I do feel guilty about"), and it's lucky I did, because I found this: Addendum 18 Oct 1998 Amos Shapir of nSOF (and of long memory!) just blackened (or widened) the spot a bit more in a mail message, to wit: 'I gather the "almost" here is because this trick almost worked... It has a nasty bug which I had to find the hard way! The "clever part" relies on the fact that if the "bvc 1f" is not taken, it means that the result could not fit in 16 bits; in that case the long value in r0,r1 is left unchanged. The bug is that this behavior is not documented; in later models (I found this on an 11/34) when the result does fit in 16 bits but not in 15 bits ... which makes this routine provide very strange results!' So this code won't work on an 11/23 either (which bashes the low register of the pair; above). I'd have been groveling in buggy math, again... Caveat Haquur (if you're trying to run stock V7 on a /23 or /34)! Noel

PDP-11 DIV instruction lossage

by jnc＠mercury.lcs.mit.edu

So, I have discovered, to my astonishment, that the double-word version of the DIV instruction on the PDP-11 won't do a divide if the result won't fit into 15 bits. OK, I can understand it bitching if the quotient wouldn't fit into 16 bits - but what's the problem with returning an unsigned quotient? And, just for grins, the results left in the registers which hold the quotient and remainer is different in the -11/23 (KDF11-A) and the -11/73 (KDJ11-A). (Although, to be fair, the PDP-11 Architecture Manual says 'register contents are unpredictable if there's an overflow'.) Oh well, guess I'll have to redo my kludgy fix to gmtime() (the distributed version of which in V6 qhas a problem when the number of 8-hour periods since the epoch overflows 15 bits)! I guess I'll have to fix it for real, instead of my kludgy fix (which extended it to work for 16-bit results). :-) I discovered this when I plugged in an -11/73 to make sure the prototype QSIC (our RK11/etc emulator for the QBUS) worked with the -11/73 as well as the -11/23 (which is what we'd mostly been using - when we first started working on the DMA and interrupts, we did try them both). I noticed that with the -11/73, the date printed incorrectly: Sun Mar 10 93:71:92 EST 1991 After a certain amount of poking and prodding, I discovered the issue - and on further reading, discovered the limitation to 15-bit results. For those who are interested in the details, here's a little test program that displays the problem: r = ldiv(a, b, d); m = ldivr; printf("a: 0%o %d. b: 0%o %d. d: 0%o %d.\n", a, a, b, b, d, d); printf("q: 0%o %d. r: 0%o %d.\n", r, r, m, m); and, for those who don't have V6 source at hand, here's ldiv(): mov 2(sp),r0 mov 4(sp),r1 div 6(sp),r0 mov r1,_ldivr rts pc So here are the results, first from a simulator: tld 055256 0145510 070200 a: 055256 23214. b: 0145510 -13496. d: 070200 28800. q: 0147132 -12710. r: 037110 15944. This is _mathematically_ correct: 055256,0145510 = 1521404744., 070200 = 28800., and 1521404744./28800. = 0147132. And on the -11/23: a: 055256 23214. b: 0145510 -13496. d: 070200 28800. q: 055256 23214. r: 037110 15944. Note that the returned 'quotient' is simply the high part of the dividend. And on the -11/73: a: 055256 23214. b: 0145510 -13496. d: 070200 28800. q: 055256 23214. r: 037110 15944. Note that in addition to the quotient behaviour, as with the /23, the 'remainder' is the low part of the dividend. Noel

PDP-11 floating CSRs: 760010, or 760100?

by fritzm＠fritzm.org

Hi folks, I have a question about floating CSR allocation on PDP-11s. Both the 1976 and 1981 versions of the PDP-11 peripherals handbook indicate the floating CSRs are to be allocated starting at address 760010. However, both the XXDP FLOAT program and simh's autoconfig suggest I should set my DZ11 (first floating CSR device in my config) to 760100. Anyone know what gives? thanks, --FritzM.

allocate floating vector for DR11-C in simh pdp11 autoconfig?

by fritzm＠fritzm.org

Hi folks, I have found it very convenient to maintain a simh configuration that parallels the physical hardware configuration of my PDP-11/45. I'm just about to add a DR11-C for a physical interface that I am building -- this will "grab" a floating interrupt ahead of a DZ11 that I already have in the machine. Does anyone here know of convenient way to inform simh's autoconfig that I wish to insert a DR11-C? cheers, --FritzM.

The ones we used in the QSIC indicator panel are, to me, pretty much indistinguishable from the lights as I recall them from BITD.

Sperry Univac UTS-40 Terminal doc anyone?

by curiousmarc3＠gmail.com

I am the temporary caretaker of a Sperry UTS-40 "intelligent" terminal (very green screen, Z-80 based terminal from the late 70's or early 80's) which I grabbed on eBait for sending parts to Dominique Carlier over in Belgium. The CRT, power supply and character generator seem to work (gives a very sharp semi-random geometric display on power-on, sometimes with a few nicely drawn characters interspersed), but the darn thing does not seem to boot on reset. The picture goes away and weird sound is emitted from the speaker after a long beep-of-death. I was wondering if anyone had service documentation. Or a dump of the firmware. Al, anything that crossed your desk? Marc

Does anyone have DEC bus edge connectors they are willing to sell? I would like to do some OMNIBUS interface prototyping and I need a way to connect to the bus back-plane. In my mis-guided youth I resorted so sawing them off perfectly good boards. I would rather not do that again. If anyone has prototype boards they have designed with fingers or dead boards they would part I will take them. My methods are crude, but effective. -chuck

radar history

by jnc＠mercury.lcs.mit.edu

> From: Steven Malikoff > I also have a book 'RADAR How it all began' by Jim Brown ... > incredibly precise recollection of the engineering Wow, thanks for that incredibly valuable pointer. My copy just arrived, and it's fabulous; it documents in great detail a part of the story that's little-known, which is the industrialization of the early radar work. There are a number of books from people on the research side (Watson-Watt, Bowen, etc), but not much on the industrial side. There is an obscure book: Frank Rowlinson, "Contribution to Victory: An Account of Some of the Special Work of the Metropolitan-Vickers Electrical Company Limited in the Second World War", Metropolitan-Vickers Electrical Company, Manshester, 1947 (which covers a lot of stuff, not just the radar work), but it doesn't have a lot of technical detail. What it _does_ have a lot of large, excellent B+W photos of the early CH, CHL etc transmitters (which MetroVick built), but not much technical detail of them. That book, and Brown's book, are a marvellous pairing, since he has the detailed description, but no images! A very complementary pairing. Noel

I am in southern California but would be willing to drive a day or so to anyone who still has an RL02 disk drive on a PDP-11 or VAX and can read it. I can bring a computer with X/Y/Zmodem/Kermit and RS-232 cables if that helps. Thanks, Paul Hardy

XT/370 microcode

by spacewar＠gmail.com

As the most obvious example of the impedance mismatch between 370 architecture and 68000 microarchitecture, the 68000 is hardwired to have eight each data and address registers, not sixteen GPRs, and microcode can't easily paper over that. Similarly, the 8087 microarchitecture has hardwired support for binary floating point normalization, and microcode can't efficiently force that to do radix 16 normalization. Both problems could be surmounted (inefficiently) with enough microcode, but the chips were designed with no significant extra microcode ROM and PLA capacity.

Texas Instruments Silent 703/707 print head anyone?

by Martin.Hepperle＠MH-AeroTools.de

Hi, last weekend I cleaned and restored a TI Silent 703 printing terminal. A rather common type with its whopping 300 baud transfer rate - nevertheless a piece of history. It was easy to fix a broken trace on the keyboard PCB (corrosion) and to roughen the idler roller for better grip on the paper. Now there is one issue left: The print head is missing one dot (infinite resistance: burnt out) and one dot prints weak (resistor seems to have twice the resistance of the others, which are all around 95 Ohms). As these terminals were produced in large numbers and the printhead/ribbon cable combo was a user serviceable part someone might have some spare parts... So: if you have a new or used part #2310472-0001 printhead, thermal I would be interested. It is a 10 wire ribbon cable with the print head. It was used in the 703 and 707 and probably also in other devices of the TI 700 Silent family. Martin

I note that the Kennedy incremental 7 inch reel drive in the NASA flight case hasn't attracted a lot of interest. That sample tape that I got, however does verify that the parity track on this telemetry stuff is unused. So that explains the 8 data inputs with no parity on the NASA model. --Chuck

Cray Origin 2000 From Indiana University Scaamp Project- Rescued

by phreakshowtelco＠gmail.com

I won an auction down at Indiana University for an SGI Origin 2000 System and 19 racks. Trip was an adventure. Rented a 26ft Penske Truck which was a junkheap in itself. Off we went. My gf and her best friend went along and had a blast. 7 Hour drive down from Michigan to Bloomington Indiana. In a rainstorm at dark. Waffle House outside of Indianapolis made for a very nice night. Got loaded up 9am yesterday morning. And headed home. Here are pics of the SGIs. And my gf's find an IBM Selectric II. Shes a typewriter lover. https://imgur.com/a/XzDXg Plan now is to start rounding up parts to fix it. It seems mostly cosmetic. Goal is to have it fully operational by VCFMW. I also found some historical info on it too https://www.hpcwire.com/1997/05/16/indiana-u-installs-64-node-origin2000/ Eventually this belongs on display somewhere. I plan to get an inventory of everything this week. and Im looking for any extra parts that anyone has for this. Thanks

Last sun3 ask: In search of a SCSI controller (VME) for a 3/260

by ian.finder＠gmail.com

Folks, sorry for the Sun spam. Everything was working in my newly acquired 3/260, and the monitor is even starting to shape up. It was a gorgeous machine until I tried to use the SCSI bus on it. The controller is dead, very dead. No fuses or obvious things. No matter the device or chain... including the original disks. ?getbyte error, phase mismatch? So again I plead- does anyone have a Sun 3 scsi controller, preferably of the internally pinned type, sitting on a shelf somewhere? Thanks, - Ian

Sanyo PHC-3100 (or PHC-3000) ?

by mattislind＠gmail.com

Does anyone have more info on these Japanse machines. I collected the infomation I got from the former owner of a PHC-3100. Interesting machines based on the TMS9900. http://www.datormuseum.se/computers/others/sanyophc3100-1 I have 32 floppies which was dumped using ImageDisk. 40 tracks, double sided, FM encoding. But none of these floppies are original so I am not sure if I have the full OS, whatever that is. I also lack documentation. >From what I understand they were never sold outside Japan.

Picked up a couple 386 machines

by lyokoboy0＠gmail.com

While working at the scrapyard today, i managed to get a couple 386 machines right as they were being dropped off. One is a pakard bell with monitor, in pristine condition. The other is a Tandy 2500 with monitor, in rough looking shape but working too. The monitor is pretty beat up for the tandy but working. I have been on the look ut for a good 386 mahine for a while now, i got kinda lucky and picked up two working systems in one day. The pakard bell is up and running fine, it was a pretty standard machine and just needed a hard drive. The tandy 2500 is pretty nice as well, it has a cdrom and a hard drive installed, although the hard drive is dead and seems to only accept AT hard drives. I am still learning about tandy computers, on my other machines, i was unable to find an 8 bit isa cad that could support newer ide drives. On the machine i just picked up it looks like a 16 bit isa slot is free, if i were to install a 16 bit ide hard drive controller for use with newer ide drives, would it work, or cause some kind of conflict with the onboard hard drive controller? The floppy drive is quite dirty but reads disks sometimes, i need to clean it up. Im hoping to post back with a couple pictures of both the machines running. I do not need them both, I really like the packard bell, but if someone absolutely needs a 386 machine with monitor I am open to offers to get one shipped out and keep the other one. --Devin

Anyone have the service guide for a Sanyo VM4209 monitor?

Hi, I'm trying to repair this monitor, but unfortunately I can't find any service manual or guide with schematics for it. I found something on www.electronic-circuitry.com<http://www.electronic-circuitry.com>, but it's impossible to download. Thanks in advance, Janek Sochaczewski

Dec-10 Day announcement from Living Computers: Museum + Labs

by RichA＠livingcomputers.org

Happy DEC-10 Day! It is my honor to announce that we at Living Computers: Museum + Labs are releasing to the computing community our Massbus Disk Emulator and all the associated software. This device connects via Massbus cables to the RH10 and RH20 interfaces on KI-10 and KL-10 systems, to the RH11 interface on KS-10 and small PDP-11 systems (including the front end 11/40 on the KL-10), and to the RH70 on the PDP-11/70. The MDE provides up to 8 emulated RP06 or RP07 disks (represented by disk files in the format used by the SimH emulation of these systems). We expect that it will also work with the RH780 on the VAX-11/780 and VAX-11/785 although we have not yet tested it in this configuration. The original MDE was designed by Keith Perez in 2005, and emulated up to four RP06 drives connected to a KL-10. The current generation was a redesign by Bruce Sherry in conjunction with the restoration of our DECsystem-1070 in 2012, and initially provided eight RP06 drives on the RH10. It has undergone continual development, with associated software created for us by Bob Armstrong, and is now being opened up for the use of the relevant communities. To this end, we have placed the design files for the hardware and the source files for the software to interface with it, along with our library of Universal Peripheral Emulator routines, on public access repositories at Github. The URLs for these repositories are https://github.com/livingcomputermuseum/MDE2 https://github.com/livingcomputermuseum/MBS https://github.com/livingcomputermuseum/UPELIB These are released under a very liberal license which will allow for free use of the MDE by any interested party. Happy Dec-10 Day! Rich Richard Alderson, Sr. Systems Engineer Living Computers: Museum + Labs 2245 1st Avenue S Seattle, WA 98134 Cell: (206) 465-2916 Desk: (206) 342-2239 http://www.livingcomputerss.org/

AlphaCom Terminal

by billdegnan＠gmail.com

The 1969-71 AlphaCom terminal is a candidate for https://terminals-wiki.org/ Here are some photos http://www.vintagecomputer.net/browse_thread.cfm?id=502 I got this from the inventor's son. I am unsure how many of these were made or put into production. The terminal kind-of worked for a while, it saves forms in core memory and transmits them like a glass teletype (i.e. datapoint 3300) and would have been a competitor machine. Unfortunately it's too complex for me to decipher, there are no schematics and I am unable to get it running again. The Sanyo TV adapted as a display is also dysfunctional now. Perhaps someone here would like to help me make progress. I have a ton of photos on my site, linked from the above thread, but doubtless more research is necessary. I am located in Landenberg, PA USA near Philadelphia due west of Newark Delaware. BIll

DEC compatible boards

by useddec＠gmail.com

I have well over 100, maybe 200 DEC compatible boards which I have no plans to use. Maybe 20 or so EMULEX, DILOG, ADAC, DATA TRANSLATIONS, and dozens or other manufacturers. Also the ones that have no company name on them. They range from a few PDP-8 boards, to Q-bus. Unibus, to VAX. I hope to have a complete list sometime later this year, bur feel free to send a wish list (off list)and I will dig through them. Thanks, Paul
