System 370 error, very sorry

by sales＠elecplus.com

The System 370 was an error. What they actually are is 5 legal-size paper boxes of 8" floppies that were used by a company for backup on a System 36. There are also "magazines" that hold 10 of these disks each. There does not appear to be any original system software, just used disks, which are prob of interest to someone who needs 8" floppies. You are welcome to post anything anywhere you want, since I want these things to go to a good home, instead of the scrap pile.

P112 question - what can you run that uses 1MB of RAM?

by jce＠seasip.demon.co.uk

On 11/06/2012 10:53 AM, Ethan Dicks wrote: > it got me wondering... what CP/M software is out > there (except maybe a RAM disk) that can *use* 1MB? There were various packages specific to the Amstrad PCW that could make use of the up to 2Mb it could take. There were task switchers like Network (which allowed switching between multiple CP/M programs) and Flipper (which allowed switching between multiple operating systems). The DTP package MicroDesign used the memory to store the page it was working on. Then there's my contributon: ZXZVM runs an Infocom Z-Code game, using the extra memory to store the game file and the up to 64k of RAM that the virtual machine requires. -- John Elliott

Those TI 1500 machines...

by derschjo＠gmail.com

The TI 1500 series UNIX machines that Isnagged off eBay a couple weeks back finally arrived on my doorstep this morning. Floating in a sea of packing peanuts in very battered boxes. *sigh*. I feared the worst but they appear to have made it more or less in one piece. Only casualty was one of the front plates (plastic) which looks like it'll be fine after some supergluing. These things are built like tanks. As the eBay listing specified, there are no hard drives. The pictures on the auction made it look like there was a drive included in one of the machines, but this was apparently removed before shipping. I was kind of hoping there'd be a drive but oh well. At least it's got a standard SCSI interface. Now to find some actual software for this thing, I'm sure that'll be easy ;). Other than that, the machines are completeand seem to be functioning properly (see the end of this mail for some diagnostic output porn, if you're into that sort of thing.) The larger of the two (it's just slightly taller than the other) has no model designation on the front (the shorter says "TI 1500 Computer", but both of them are labeled as S1505s on the rear, with S1507 processors and differing options installed. The taller POSTs as a 1507, the shorter as a 1505. Dates on EPROMs are from the early 90s. (91 and 92). The taller (1507) has a 68040 CPU (25Mhz), 64mb of RAM (30-pin 4mb simms, parity), a Communications co-processor, ethernet, and a couple of other communications adapters(a "Multidrop\V.35 and some misc "Comm Carrier" boards). Looks like the 68040 is an upgrade of sorts (looks to be official) -- the two machines have the same motherboard, but the 68040 is on a daughterboard that plugs into the 68030 socket. The shorter (1505) has a 68030 (25Mhz) with 68882and only8mb of RAM (30-pin 1mb simms, parity). Aside from a"Comm Carrier" board it also has an 8-channel async serial boardwith 8 MMJ connectors on the rear. Near the bottom on the rear there is a pair of ports (DB-25 and MMJ) labeled "DIAG PORT." I connected a standard DEC MMJ to it and at 9600N7 I get diagnostic output(see below). Other interesting things of note: There are a lot of 68K-series processors in these machines. Aside fromthe main 68040 CPU, there are two 68000 CPUs on the motherboard, one for COMM I/O, the other for SCSI (they're neatly labeled). The Communications coprocessor board contains an additional 68010. Diags indicate that the boards are Nubus, though they don't use the standard connector I'm familiar with. Looks more like PCI/microchannel. That's all for now. I've taken some pictures which I'll post later. If anyone wants more details, let me know. And if anyone knows where to find OS tapes for thisthing, I'm all ears.

A few corrections/additions to the Kerrville inventory

by sales＠elecplus.com

The IBM System 370 software is an error. There are a hundred or more 8" floppy diskettes, some in "magazines" that were used as backups on a System 36. Occupies about 5 legal-size paper boxes. There does not appear to be any original software. AT&T 3B2 software and documentation, 2 legal size paper boxes, much of the documentation is still sealed. Sorry, I do not have any more of the 3B2 machines. Large qty of 360K and 1.2MB floppy drives, and 360kb new blank diskettes in 10-packs. TI 99/4A, 1 still in original box, several out of box, extra AC adapters, small amt of software. Commodore 64, 1 still in box, several out of box, couple of disk drives, etc. Bring software to test. LOTS of color and mono 9-pin monitors, a few still new in box. LOTS of dumb terminals, some kbds. A few Atari game systems, extra AC adapters, etc. Bring games to test. ISA and PCI cards, thousands of them, plus "newer" AGP video cards. Several boxes of CPU chips, from 80386 and 80387 thru P4. Motherboards, new and used, from 386 to Quad core P4. Thousands of cables, etc. Over 10,000 square feet to look through, I look forward to seeing you! Email inquiries welcome.

Ton of PDP-11 Stuff in West LA

by bdamer＠digitalspace.com

CC folks, I just received this note from a Rufus Crosby whose recently passed brother in law has a ton of PDP-11 stuff in the West LA area, I am passing this on to you, feel free to contact Rufus at: RufusRufus at aol.com From: RufusRufus at aol.com Date: Tue, 6 Nov 2012 03:01:59 -0500 (EST) Subject: Re: DigiBarn Computer Museum: Comment submission form. To: bdamer at digitalspace.com panded to false Hi Bruce, My brother in law's estate has a lot of PTP11 stuff, hardware stuff, manuals and literature. That stuff began to become obsolete and he could get it for almost nothing at the swap meets and he would come back with car loads of it. I am not a computer guy, I know nothing, I mean zero, about the products of the Digital Equipment Corporation but I would hate to see stuff going to landfill that somebody would really want or treasure. It would require somebody to inspect all the stuff to find if there was anything of interest in it. None of us have any idea of what he had or where it is. It is a real pig in the poke. Still, if somebody has real interest, have them get in contact with me and maybe we can come up with some plan. I am sorry, but I just don't have an inventory of what he has. Nor has anybody else.

AT&T 3B2/500 needs a new home

by corey＠electricware.com

I have an AT&T 3B2/500 that needs a new home. I've had it since it was pulled from service about 13 years ago. It's in great cosmetic shape and would make a great addition to the right person's collection. I don't know how much memory it has or the size of the hard drive, and I haven't personally fired it up. If interested, please drop me a note, otherwise it's going to get recycled. I live in the Portland, Oregon area and would prefer to have someone pick it up and I'm not really interested in shipping it. Thanks, Corey.

Paging NE-Z80 owners! Paging NE-Z80 owners!

by rrr_lopes＠yahoo.com.br

Hi Alexandre! I did not had a NE-Z80 but an early model TK-82C. It had a SLOW function at the keyboard but it lacks the circuitry to proper respond to it.I can say it used a copy of the ZX-81 EPROM. When later I built a SLOW pig board circuit it worked as expected on original ZX-81. The TK-82C and NE-Z80 circuit was identical to ZX-80. And behave like the ZX-80 if you adapt it's EPROM to those. What Microdigital (TK-82) and Prologica (NE-Z80) did on those time was use standard parts. Copying the ZX-80 circuit to avoid the custom chip used in ZX-81. So , Yes, you can use the ZX-81 ROM image in a NE-Z80 as it had the same and exactly content. The ZX clones started to differ from the original when they started producing TK-85, CP-200 and others. Some licensed by Sinclair, I Believe.

IRIX remote display

One special thing is accelerated 3D with OpenGL vs. IrisGL: Newer SGI applications (=clients) use OpenGL, these have worked without a problem. But older SGI applications use IrisGL, the predecessor of OpenGL. When I tried it last a few years ago, these would only say: "server does not support IrisGL" or the like. There's another issue related to nfs networking between Irix and Linux (needs -o proto=tcp or proto=udp or similar, I always forget it and have to look it up...). Without the option, only minimal transfers will work, whereas even a longer directory listing or - certainly - a file transfer beyond a few KB would cause the connection to stall. But I have no indication that anything similar would apply to X11 as well. Kind regards, Joerg On 11/04/12 19:00, cctalk-request at classiccmp.org wrote: >>>> I figured that as well, and I haven't had any problems with Solaris, HP-UX, >>>> AIX, etc. doing remote displays >>>> to a different "brand" X-server, nor have I had any problems with IRIX -> >>>> IRIX, but mix up IRIX >>>> and others and I have had trouble. -- ------------------------------------------------------------------- Dr. med.

OT: welder conversion for PSUs

I have a Fuji PEX391-30 850W PSU that works with the Sun-4/260, 280, 360, 380 that has been offered several times and no one seems to want. Given the warnings of "capable of welding" on higher-output PSUs, has anyone actually converted one to be a spot welder? I don't think it will do arc.

Seagate hard drive for PDP-11/23+

by earl＠retrobits.com

Greetings, I love the dual RL02 drives on my PDP-11/23+. It's great fun to hear them spin up, and they are a neat conversation piece. However, I fear that ongoing operation will eventually lead to their demise (as with all things). I'd like to move to a (slightly) newer technology. My goal is to: 1. Purchase a Seagate ST-225 or ST-251 hard drive in working condition. 2. Build a cable and interface assembly as described at http://home.windstream.net/engdahl/rqdx3.htm, and put the drive in an external case/PSU. 3. Properly insert my RQDX3 (in my stock, but not in the machine) into the PDP, and connect to the drive. 4. Use the ZRQCH0 utility in XXDP (perhaps loaded from a TU58 emulator) to format the drive as a RD31 or RD32 (depending on the Seagate model). 5. Determine how to boot from RT-11, and perhaps TSX-Plus. Is this doable? Will the KDF11-BA built-in bootstrapper ROM boot from a RQDX3? Also, my RQDX3 card is assumed working, but untested. Is there any way to test the controller board functionality without having a drive attached? Thanks for any thoughts! - Earl

IRIX remote display

by saquinn624＠aol.com

What non-IRIX X-servers have people been able to get to work with IRIX? I'm not talking about the DGL problems (where older IRIS-GL programs don't work right with non-IRIX X-servers excluding the IRISVISION because of the absence of Distributed GL), but I'm getting artifacts (Mac OS X 10.4 X11 [incomplete menus], Solaris 10 [boxes]) or, more annoyingly, random X resets (Linux and other X.org derived stuff). This is recent IRIX on the client (6.5.22 and .30).

RS/6000 B50 memory

by saquinn624＠aol.com

I have a RS/6000 B50 (rackmount version of the 43p/150). I know it takes PC100 168-pin ECC Registered DIMMS, as I have one 128MB stick in there now from the parts bin, but that's my only one. I'm trying to get some more memory to make it useful, but local suppliers only have 512 and 1GB sticks, and per IBM 4x256 is the maximum supported memory. Does anyone either have 256MB DIMMS to sell or know if the machine will use larger capacity DIMMS?

New absolute filters for DEC RL01/2 drives -

by jack.rubin＠ameritech.net

I found a cache of NOS RL01/2 absolute filters (equivalent to DEC p/n 1213097) at the Filter Factory in Santa Ynez, California (www.thefilterfactory.com), phone 805.733.2180. They have 47 in stock. Price is $28.60 each, shipping for a single filter to 60091 (Illinois, USA) was $8.27. I ordered one to verify dimensions and construction - perfect match for the original part. The filters were manufactured by HEPA Corporation (still in business) but minimum order quantity >from HEPA is 100 units. Filter Factory will _not_ be ordering after the current stock is gone. Get'em while you can! Jack

Terminal trouble

by saquinn624＠aol.com

I have a Wyse WY-150 that I use as a console for several machines, and it has an odd and irritating behavior on some machines. For SGIs and DECs the text gets messed up. O300 will get garbled, but my suspicion there is that the terminal doesn't really handle 38,400bps right. On all SGIs and DECs there are spacing issues, though - Example: in SGI startup diags and PROM whether I'm in 80 or 132-column mode there will be one letter on the far right and then it wraps around. I'm in VT220 mode, and it does it in both 7-bit and 8-bit. I didn't notice this on my old Altos III-branded Wyse. Anyone fixed this?

CP/.M Floppy Bood Diskette needed...

I recently acquired a Televideo TS-801. It's a typical Z80 CP/M system. I've have it restored to where it is trying to boot. It "says" that it is in the process of "IPLing" the system and the left drive is selected. I couldn't find any TS-801 boot images, but based on CC archives, I saw that Televideo TS-802 floppy images will work as well. I downloaded TS-802(H) images from Dave Dunfield's site - but they expect a HDD - and fail booting... Does someone have an CP/M boot image for the floppy based TS-801 or TS-802? If so, I'd appreciate a copy off list or link to same on or off list. Thanks! Lyle -- Bickley Consulting West Inc. http://bickleywest.com "Black holes are where God is dividing by zero"

Fwd: HP 524B Military Version

by hilpert＠cs.ubc.ca

I have been contacted by a fellow with an FR-38D/U digital counter, I gather he would like to let it go. This is a tube-based digital electronic counter, identical to the HP-524B, but I think the particular unit at issue was actually manufactured by Northeastern Engineering. (I've never understood the relationship, but AIUI Northeastern manufactured/second-sourced some HP designs.) Here is a photo of the unit: http://i142.photobucket.com/albums/r84/onegroovydude/ 62E116DF-2C75-459F-ADE4-44FA2B79B712-285-00000017B3222DC6.jpg For more info about the models, here are my web pages about the 524B and HP-520 instruments: http://www.cs.ubc.ca/~hilpert/e/edte/HP524B/index.html http://www.cs.ubc.ca/~hilpert/e/edte/HP520/index.html These things aren't computers of course, but they are some of the last pieces of tube-based digital electronic instruments, i.e. the same technology as the the 1st generation of electronic computers. Marketing spiel: You're not likely to ever own a digital tube computer, but you can own a digital tube counter. I'm just helping to see it preserved, you can contact Travis below if interested. I get questions and expressions of interest in these instruments every now-and-then due to my web pages, but I have no idea what sort of dollar/market value to assign. The location is Kansas City. They're over 100 lbs and you'd have to be really enthused to have it shipped - so hopefully someone can pick it up. If someone obtains this unit, I can supply the schematic, at least for the HP version. (I have a 524B and 524C that I have repaired.) If someone does obtain it I'd be interested to hear about it.

Microvax II won't boot, hardware error?

Geneb wrote: > >Do the old license PAKs work on newer releases? I've got a few from the >5.x era... > >g. There's the license and then there's the PAK. The PAK will probably work (there are certain limits with capacity and VAX vs Alpha vs I64), but the license may or may not have transferred from the P.O. and may or may not (probably not) be valid for a newer version of VMS. DEC did not tie them to hardware as a matter of policy, and many/most PAKs don't have a version encoded in them. The PAK was a means of encouraging compliance, not a futile attempt to force compliance, and so they didn't trick it out to be as obnoxious as they could have. You should probably get a new hobbyist license from the program (they're cheap), whether you choose to use your PAKs or the hobbyist ones is up to you (but keep in mind that you still do need to renew your license every year for the hobbyist program).

Mac SE/30 restoration

by dgriffi＠cs.csubak.edu

I have a well-treated Macintosh SE/30 that I'd like to fix up. Problem 1) Whenever the CPU is doing something or something is being read or written, faint warbling screeches can be heard coming from inside. The volume control does nothing to quell this noise. Problem 2) The image on the monitor is canted a few degrees clockwise -- enough to be noticable and irritating. Problem 3) I've figured out how to format a Mac floppy under Linux and transfer files by floppy, but I'm unclear how I should get two needed utilities: binhex and unstuff onto a Mac floppy without mangling the resource and data forks.

It's particularly important as with film you are enlarging the 35mm stock by several thousand percent when scanning into the digital domain. A "pixel" in the conversion is considered to be the smallest object that can be resolved and reproduced by the film or sensor. When using that comparison, a 35mm print is roughly 20 megapixels, or 8K resolution, assuming the film was shot and developed under ideal conditions. Scanning at any higher resolution doesn't buy you more detail, as you start getting into the grain at that point.

6 bit encoding

by brian＠quarterbyte.com

Hi all, I'm decyphering an encoding scheme that was used to compress source code decks. It's from an old obscure IBM 1130 program (CMXP, written by Wil Baden, part of set of enhancements that let source code be stored, edited, and compiled directly from disk. Radical! Visionary!) The compressed format uses 6 bits to encode each character, but it's not any of the standard IBM 6-bit EBCD schemes I've found through Google. It *might* be unique to this compression/decompression program, whose source I haven't found yet. (And if the source does turn up it'll likely be compressed using this format -- so unless the character codes are in the source as hex constants, the source may not help). Here is what I've been able to map out so far, from a small fragment of an encoded source deck: Hex value 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 00 sp A B C D E F G H I . ) 10 + J K L M N O P Q R * 20 - / S T U V W X Y Z , ( 30 0 1 2 3 4 5 6 7 8 9 = where "sp" is space. I am absolutely certain of the encoding of the space, alphabet, digits, slash, comma, period, parentheses, and asterisk. I'm pretty sure of the plus, minus, and equals. For the ones I've left blank, I have no idea yet; either the codes aren't in the sample I examined or I can't guess what the character is from the context. If I read in more cards they might become clear. I've found some CDC codes where / precedes S, but the row ordering is different. Does this encoding ring any bells for anyone? (Again, it might not belong to any standard). Thanks Brian

Writing an AST in VAX-Pascal

by jonas＠otter.se

I did this in the '80s and it worked very well, I used it as a kind of software interrupt in a communications handler that had to handle both input and output at the same time from the same terminal. Unfortunately I don't rememver exactly how I did it, and I no longer have access to the source code. But I did find this in the HP Pascal for OpenVMS User manual, section 5.1.4 on page 5-6: Asynchronous system trap routines (ASTs) and RMS completion routines must have both the ASYNCHRONOUS and UNBOUND attributes. Because they are asynchronous, such routines can access only volatile variables, predeclared routines, and other asynchronous routines. The Language Reference mentions the User manual near the end in conjunction with volatile variables. You might also need to declare the variable p as volatile somewhere. The User manual is here: http://h71000.www7.hp.com/doc/82final/6140/aa-pxsnd-tk.pdf You would probably want to read chapter 5 in there. Hope this helps. /Jonas

dead sca scsi hard disk

by teoz＠neo.rr.com

I have a Seagate ST336706LC (10KRPM 36GB SCA-2) HD that quit working one day (doesn't light up, isn't detected, no humming or spinning). Was wondering if there is a fuse or something fixable on this drive (I kept my hardware drivers on it and not all of them are backed up). Mostly just want to get the data back before I toss it if possible. Any ideas?

PLCC extraction tool

I may need to do this a few times, but I generally don't find the need to do it. Is a specialized PLCC extraction tool really required/much easier/safer/etc? There seem to be a ton of tools online starting around $2 US a piece. If I'm going to spend the time/shipping to order one, I may as well get a decent one. Can anyone recommend a specific model/US source for it? Warning, levering them out with a tool can easily crack the socket, then you will get poor contact. I've got a $10 tool that easily fits the larger sockets, but the first time I used it on a 68-pin PLCC, the pulling hooks broke off. I filed new hooks out of decent steel and brazed them to the existing tool's arms, and it works great, now. So, I can't recommend an off-the shelf tool that actually works well right out of the box.

searching for Unibus disk controllers

by shadoooo＠gmail.com

Hello, I'm searching for Unibus disk controllers for my 11/24 and 11/730 machines. It could be ESDI, SMD or better SCSI, of course the price will change. Also an RL02 or RX02 interface could be interesting, if somebody has one to rid of. I already have an SDI interface, but no SDI working disk, unfortunately... Preferred location is within EU.

B6700 story from Sharktank

by jws＠jwsss.com

From the Computerworld Sharktank. I think this also the system with the B in the lights as well. Flashback to the mid-1960s, when the Control Data 6600 computer was the fastest thing going, according to this IT pilot fish who remembers it well. "It was about 1 megaFLOPS," says fish. "The operator console, manned 24/7 of course, had two large, circular CRT screens, side-by-side, that almost always displayed operator messages scrolling up the screens. As long as those messages were scrolling, the operator seldom had to pay attention to them. "But the CRTs were actually vector displays, capable of more, under program control. "It's 2 o'clock in the morning. Halloween. Suddenly, the two screens go blank. Then two closed eyes appear. Slowly open. Eyeballs look slowly to the left, then slowly to the right -- then slowly stare straight ahead. Then eyelids slowly close, the two displays blank, and go back to scrolling plain text.

DSO / logic analyzer buying advice

by keithvz＠verizon.net

I currently have a dual-channel 30mhz analog scope, the Intronix 34-channel 500mhz 2k samples max logic analyzer, a Saleae Logic 8-channel 24mhz unlimited samples and a (much) older 60mhz DSO on it's last legs. The 30 & 60 mhz analog scopes are simply too big and cumbersome to use. These new scopes are much smaller and more convenient. For logic analyzers, I have FAST, WIDE, but short buffer. And a slow, narrow, mega-long buffer(limited by PC RAM more or less). These both have their good points but to round out my tools, I need something that ballparks 200mhz, 32-channels, and decent buffer. What's a decent buffer? I don't know exactly. I know 2k isn't even close. And that a million+ is really nice. These are both PC-based logic analyzers and I'm fine with that. The software is sufficient with both and gets me the measurements I need. Of course, I'd prefer standalone units but still would like to export data to a PC (say via USB or serial). This would simplify the process and the UIs of dedicated devices have usually been thought out a little more than the PC software..... I was seriously looking at a Rigol DS1102D which is 100mhz, 16-channel LA + 2 analog channels. My only real beef is that it's 16-channels and not 32. Could really use 32 to do a 16-bit data bus and other stuff (partial address, etc) I can't easily tell looking at the specs what the depth of the LA would be. Would I simply divide the 1 million point memory by the 16 channels? http://www.rigolna.com/products/digital-oscilloscopes/ds1000d/ds1102d/ Rigol's have gotten great reviews. Or do I get a scope only, and then use something cheap like this http://dangerousprototypes.com/docs/Open_Bench_Logic_Sniffer and solder another 16-pin header onto that and go 32-channels, 200mhz, 6k depth. Or buy a kickass eval board and hack SUMP onto it, and get a deeper solution..... While I'm a huge fan of HP and Tektronix, and I know there is old hardware at reasonable prices --- I don't want to mess with trying to piece parts a large mainframe together from untrusted sources, and spend time trying to fix something like that. Plus, the specs are normally not even close to that of modern equipment. I'd rather invest time hacking verilog onto a new eval board that has plenty of fast memory............... Any discussion would be helpful. Thanks, Keith

Apparently this is the 2nd revision which does correct some errors. From the chapter previews I'm surprised how much information is in the book. I haven't bought or read it but it's certainly tempting and definitely seems like enough to get someone with the equipment up and running these days.

Surplus DE9F to 8P8C adapters available

by tothwolf＠concentric.net

I have a large number of surplus DE9F to 8P8C (RJ45) adapters available if someone can use some. I counted at least 350, but I'm not sure of the exact number. When I bought them many years ago, I was expecting to get adapters that had all 8 wires present (based on the photo the seller provided) but what he sent me were pre-wired and three of the wires are clipped away down inside the adapter body. (It might be possible to extend those three wires, but I didn't want to spend the time on it.) The adapters are labeled with a "PC" sticker, so I have to assume they were originally used to connect to a PC serial port of some sort. (Mixed in with these were a handful of DE9M to 8P8C adapters labeled "UPS" that have 5 wires similarly clipped away). These are located on the US side of the pond, and whoever might want some will have to cover the postage. I don't think these adapters are really worth very much, although I certainly won't complain if someone wants to pay something for some of them and help offset my original purchase cost. I didn't pay /too/ much for them, although I doubt I'd have bought them at all had the seller been up front about what he had. If these adapters sound useful at all I can see about taking some photos and a work up the pinout. I just really can't see me ever using ~350 of these things :)

Writing an AST in VAX-Pascal

by robert.jarratt＠ntlworld.com

It has been many years since I wrote any VAX-Pascal and I find myself needing to write an AST. I have looked around in various documentation but can't find any examples. The AST I want to write is in response to the completion of a QIO. The QIO call looks like this: Stat := $QIO(0, Channel, IO$_WRITEVBLK, , %IMMED SendCompleted, 0, Buf, Len); And the AST itself looks like this (no body at the moment, just want to make it work first): [ASYNCHRONOUS] PROCEDURE SendCompleted( P : UNSIGNED); BEGIN END; When I run the code though I get a runtime error: %SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual address=00000000, PC =000008C1, PSL=03C00000 %TRACE-F-TRACEBACK, symbolic stack dump follows module name routine name line rel PC abs PC DMC11SEND SENDCOMPLETED 67 00000009 000008C1 801D58F3 801D58F3 0001E893 0001E893 DMC11SEND SEND 77 00000070 00000938 DMC11SEND DMC11SEND 111 00000179 000006BD I am not sure what I have done wrong, anyone know?

> Wait... That Ken Rockwell article says *nothing* about film > grain. I even searched it for the word grain. How on earth > can you write an article about the relative resolution of film > without a word regarding grain?! That's right. If anyone starts believing that "no grain" is the same as "high resolution" then we end up back in the mushy microdol-X era where every photo is just... blah. I far prefer a nice roll/sheet of Tri-X or HP5 developed in a high-acutance developer that really makes for obvious sharp snappy grain. Oh it's so beautiful. For fans of color... the 1600 color slide films available in the late 80's/early 90's, when push processed a few stops, are amazing. Astoundingly huge and sharp color grain. I love it. Tim.

Diagnosing and Reparing Commodore 64s

by ark72axow＠msn.com

Hello everyone, I was hoping for some definite direction in my endless quest to fix my C64. I don't have a lot of free time to work on this. So it is ongoing in many ways. Plus I am cautious about doing things that I know little about. Which can be good especially when you get people that give you conflicting advice. I do find a lot of helpful people on IRC, but you have to sort out what they are all telling you. I won't want to go and start buying all sorts of stuff and equipment without knowing why or then finding that I should have bought Y, when I bought X. I know a little. Bits and pieces here and there, but nothing that will give me confidence to just dive in. This is my quest to learn how to repair my C64: I started with my original C64 which I bought in 1987. I had left it in a garage for two years and then tried to use it and it didn't work. First I was told that I should clean my C64 with regular dish detergent and a hair dryer. I was told that this would solve many problems. Sounds unsafe, but I guess I will try it. Then I was told that I should buy another C64 since it isn't worth repairing them, since they are so plentifully available and cheap. So now I have many non-working ones. Then I need to replace chips that are bad, so I need to know how to solder and de-solder. Which kind of device to get ? There are different wattages and if you do it wrong then you burn up your boards (as a friend of mine did with more soldering experience did). Do I get a combination desolder sucker ? Or a little squeeze one ? Or a push and suck stick ? Do I get a soldering station ? A braider ? Too many different choices and combinations. I prefer something that will work and not damage my boards, and for desoldering, something that won't give me repetitive stress injury. Then I'm told to get a diagnostic cartridge for C64, which works well expect when the PLA chip is bad and there you can't see video. Then I should get a diagnostic harness, which works better, but again you need video. Then I find a Diagnose 64 cartridge which tells you which chips are bad very simply with LED lights, but they are hard to find. I'm borrowing one right now from a friend and figuring out how to use now. Then I'm told to get a multimeter, how do I use ? Which one to get ? I get one, then I'm told there is a better that could have been gotten for a little more money. Then I'm told to get a logic probe. Which one ? Again, how to use ? Then I'm told a logic probe is not as good as an oscilloscope. Which one ? How to use ? Then I'm told that I don't need an oscilloscope. Then I'm told to go to Ray Carlsen's site and that will have everything I need. http://personalpages.tds.net/~rcarlsen/cbm.html. Which is very nice, but I'm a beginner and I don't need just a bunch of schematics and reference material. I need step by step method which explains which tools, techniques etc. that I need to do. Then I'm told that going to the Rob Clarke and Bil Herd workshop would give me everything that I need to know. It is good information, but not hands on. Jeff B

RISC OS for Raspberry Pi released

by lproven＠gmail.com

Don't know if this is "classic" enough, but it might interest some people... https://www.riscosopen.org/news/articles/2012/10/26/risc-os-pi-released-ris… There is a final, complete, stable version of Acorn's classic Archimedes OS now for the Raspberry Pi, making the RPi the cheapest Acorn-compatible there's ever been by a long way. It's based on ROOL's RISC OS 5.19, the latest version of the shared-source fork of RO, based off Pace's version. (That's Pace the satellite-TV/set-top-box/modem company.) RISC OS Ltd is still developing its closed proprietary version based off Acorn's unfinished betas of what was to become RISC OS 4 and still claims that Pace/Castle's version is unauthorised and not legitimately licenced. However, nobody much cares any more. ROL hasn't released a new version in several years and doesn't support modern and recent ARM hardware such as the Iyonix, BeagleBoard, PandaBoard and now Raspberry Pi - it basically just sells (quite expensive) updates of RISC OS 4 for classic Acorn hardware and directly hardware-compatible machines.

For any earlier version ask around (also give location). HP has said in the past that they have no problems with hobbyists borrowing media, but they continually reiterate that they would not like to have it posted for public download. There are probably people on here who have it (I have 5.5-something, 7.2 and 7.3) , or you can ask on the OpenVMS Hobbyist fora.

Maybe something is hanging up the Q-bus, or you have failing memory. If you have diagnostics, running a memory test for a while may get you somewhere. Otherwise, I'd look into trying to pinpoint the problem by removing memory modules and see if the system becomes more stable (assuming you have multiple memory cards, of course). -Rick Memory is NOT on the Q-bus, it has it's own dedicated bus on the C-D connector rows (how many slots are memory only in the CD rows depends on the specific backplane.) Possibly you might have a Q-bus board in a memory-only slot, that is certainly something to check. Otherwise, you may have a bad memory card, a bad or dirty slot, or possibly a bad CPU board. Hmm, I've never seen this error, but I think if a peripheral board is bad, it does not cause a machine check, but maybe I've never had the specific error. Can you tell what the physical address was? or, at this point, might virtual=physical? If so, is 7FF3xxxx in the Q-bus I/O space? Jon

Wanted: DEC Rxxx module photos

by v.slyngstad＠frontier.com

Hi, Today I have finished documenting the Rxxx "flipchip" modules in my possession. These are the modules from which most straight-8 and PDP-8/S gear was constructed: http://www.so-much-stuff.com/pdp8/flipchip/flipchip.php http://www.so-much-stuff.com/pdp8/flipchip/Rxxx.htm The Rxxx modules are a smallish subset of the larger DEC modules space: http://www.so-much-stuff.com/pdp8/flipchip/modules.htm Unfortunately, there are several Rxxx modules for which I have neither example or picture: Module Versions Description R211 K* L* MB, PC, MA, (PDP8) R212 A* J* MQ (PDP8), 2 FFs, SR, SL, Read-in, Clear R220 F* L* 3-Bit SR, Parallel Read-in, Diodes out for detecting all 0s in R111 node R284 A* Quadraflop, PDP8, 4 stable states R450 D* E* Clock for use with TTY, first pulse comes 1/2 period late R451 E* Teletype Clock, for faster teletype think R450 R601 B* F* H* Pulse Amplifier, 6 DCD Gates, 100 or 400 ns pulses R613 B* R603 that cannot be triggered from output, with 5 mA loads R650 E* Bus Driver, 2 circuits, 2 Inputs & Node (* just means I don't have a board drawing for it yet) There are also some more exotic modules for which I lack even a schematic: R012, R1110, R1130, R152, R200, R406, R407, R408, R623 and I don't expect to be able to locate or do much about those. Anyway, what I'm looking for is some help with the former list. If anyone has examples of these, would it be possible to photograph the component and solder sides with decent resolution and forward the photos to me? (You are welcome to forward the whole module, but I don't expect that :-).) The version information just refers to versions that I have schematics for. Any version you have is fine. I am particularly interested in the R2xx, as those are key modules for the straight-8. Thanks in advance for any help anyone can provide. (Meanwhile, I'll start drawing Sxxx modules.)

PERQ monitor problem (was HP 9845 power supply diagnostics)

DomainOS and Domain Keyboard for one HP9000/400

by spedraja＠ono.com

Just today installed in my computer room my HP9000/400. It's an Apollo compatible machine, as far as I can see (Domain keyboard support in back, etc). It comes with NetBSD installed (1.9.2 version, very limited), and it works, but I should like to get a copy of DomainOS (and the keyboard, I suppose) and UP-UX (...9.xx version perhaps ?). Oh, and one transceiver from AUI to RJ45 would be fine too... I gor one but for I can't locate it. If someone can offer this bunch of items I should like to talk privately about a trade. Thanks !

Computermuseum der Fakultät Informatik at the Universität Stuttgart

by michael.99.thompson＠gmail.com

Klemens Krause and Christian Corti, the caretakers of the Computer Museum at the University of Stuttgart, opened their museum on a Sunday so I could have a short visit. Well, the short visit was so fascinating that it lasted for over six hours. I really appreciated them giving up a large part of their weekend for my visit. I primarily wanted to see their collection of DEC PDP-8 systems because of my current restoration projects. They have a very nice looking and functional Classic PDP-8 system with a Tennecomp tape drive that is very similar to an 8-track cartridge. Their LAB 8/E has lots of peripherals, including a Votrax voice synthesizer and X-Y scope display. We also got to see their IBM 1130 and the Librascope LGP-30 running. That was the first time I have seen a vacuum tube computer running. It was quickly apparent from the demonstrations that just about everything in the room was interconnected so almost all of the peripherals could be connected to a system with the flip of a switch. They have extensive demonstrations that they run to demonstrate the capabilities of both the systems and the peripherals. If you are in Germany you really need to make an effort to visit the Computermuseum der Fakult?t Informatik. Klemens and Christian are very capable and very enthusiastic about their preservation, restoration, and demonstration work. http://computermuseum.informatik.uni-stuttgart.de -- Michael Thompson

Digital / DEC RGB cable

by hollobon＠gmail.com

Hi, I have a Digital RGB cable here if anyone wants it for the cost of postage. It's got a D-sub shaped connector on one end with three circular connectors inside marked A1, A2 and A3, and 3 RGB BNC plugs on the other end. Says BC29H-2E REV-BOI 47746 on the d-sub shaped plug. I'm in the UK. Cheers, Pete.

Blue screen of Basic

I >>> >> desperately need a shutter speed tester for some of my older gear. >> > >> >Make one! Although there is a trap for the unwary that most comemrical >> >testers get erogn too. > I plan to. Several years ago I built a simple shutter speed tester with two phototransistors on a piece of perfboard. It is meant for 35mm cameras and has the phototransistors spaced 18mm apart, 9mm from the edges of the frame, so that they are equally spaced from the centre of the frame, half the frame width apart. The transistors have 10k collector resistors and are fed from a 4.5V battery supply. The collectors go to the tip and ring of a 3.5mm stereo plug, which plugs into the line (or microphone) input of my laptop. I strap the perfboard behind the shutter of my camera with rubber bands and point the camera at a lamp. I then use Audacity to record the output of the tester when I fire the shutter. If you display the recorded waveform from a focal plane shutter, the two channels will show when the shutter curtains pass each phototransistor and you can then easily work out the shutter speed. IIRC it will also show if a curtain is slow near one end of its travel. Obviously, it also works for blade shutters, both traces will then show the same. Also obviously, the transistors are fitted behind holes in the perfboard so as not to foul the shutter curtains :) You can find several versions of this design on the net by Googling. It works quite well. You will probably find that speeds down to about 1/250 are correct, and 1/1000 will be quite badly off and cannot be made correct. /Jonas

amusing google image search results

I noticed that doing a google image search on the string {kaypro 2/84} yields an interesting array of pictures that have nothing to do with Kaypro.
