I just spotted a Compaq portable 3 in a 1980 "flashback" scene of Psych. A useless observation, it had the expansion bay on the back. "Psych" High Top Fade Out (2009) Season 4 episode 7 There appeared to be something like a Commodore 64 driving a display on camera. the CP3 was not powered on. Not sure if anyone here had anything to do with a loan or elsewhere, or if the film company owned it. Jim

Can you read rx02 or rl02 disks ??

by system11＠bigpond.com

To all, Happy New Year and good luck in 2011. Being new to this site, I have some requests for help. Question 1. Anyone with a working pdp-11 with rx02, I have some diskettes I wish to recover data and programs from for use with Robert Supnik's pdp-11 emulator, can you make a disk image suitable for above to email me. I am happy to pay you to do this and return the floppies to me. Question 2. As above but 4x RL02 cartridges, but if you can get the images, you can keep the disks. If you have both rx02 and rl02 would save time and postage. For those fussy about copyrights I have valid licenses and full documentation for RT-11, TSX+ and S&H Cobol, but unfortunately no longer have a machine to read them. (Hindsight is marvellous) Thanks in anticipation, Royce Smith Southern Highlands, New South Wales Australia system11 at bigbond.com

Where to get VXT software?

by james＠slor.net

I have a DEC VXT 2000 that I would like to try out, but I don't have the software to host for it to load up the X environment across the network. Anyone know where I might still obtain the bits? Looks like the last version *may* have been v2.1g? Thanks! James

Wanted: X/PEX terminals

by legalize＠xmission.com

The recent discussion of VXT2000 reminded me of X/PEX terminals. I'm looking for X Window System terminals, particularly early NCD models before they switched to using PC keyboards. I have several NCD 19s, see right hand side of this photo: <http://manx.classiccmp.org/collections/cgm/sprawl4/dsc_0608.jpg> However, I don't have any of the color X terminals from NCD for that period. Also, I have *no* PEX terminals and this would be a very welcome addition to the collection of the computer graphics history museum. I have a number of small box type X terminals from NCD, Tektronix and IIRC even an HP branded one. They are from late in the X terminal marketplace where they all had become fairly identical: small rectangular boxes to which you attached a PS/2 keyboard and mouse and a VGA monitor. I can post a list of the exact inventory in the museum's collection if that will help avoid duplicates. -- "The Direct3D Graphics Pipeline" -- DirectX 9 version available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

Hi, Good news on the S-100 8086 CPU board. First confirmed working installation "in the field" AFAIK. If we've gotten this far, I think demonstrating a working CP/M-86 will be along shortly. John already has CP/M-86+ running in the lab. http://s100computers.com/My%20System%20Pages/8086%20Board/8086%20CPU%20Board .htm Thanks and have a nice day!

Software wish list

by g-wright＠att.net

Hi, All I'm back at the grind trying to find a few old OS's The first is for my TEK DPO (WP 1210 Digital processing scope ) this is a 7704a scope with a P7001 Digital processor that connects to a DEC PDP 11/05 . It runs on TEK Basic (8" floppy or DEC tape}.. The official name is "TEK SPS Basic V02" There is also a system test disk. This uses a TEK 4010 Terminal for a display. The second is a Pertec Mini ?? coax system 4010 Don't know much about it other than it used coax to the dumb terminals instead of Serial.. (1/4 " Tape) The third is a OMS Zues 4 I beleive it ran cpm or mpm (5 1/4 disk) The forth is a Tek 4051. looking for the Tape images. The fifth is a Tek 4404 computer. Looking for the disks (5 1/4 floppy) I can handle most image files. Or would gladly pay for a Disk or tape. If I missed somewhere online, point me in the right direction Thanks, for reading this Jerry Jerry Wright JLC inc g-wright at att.net

I've for sale a HP-85 with a QIC40/80 modified tape drive including: ROM drawer with : 1 Matrix ROM 1 Mass Storage ROM 1 Input/Output ROM 1 Printer/Plotter ROM 1 Advance programming ROM 16 K RAM module HP-IB module HP 9121 double 3.5 disc drive 2 QIC40/80 tapes (1 empty, 1 containing the Standard software) 2 3.5 inch disc's (NOS) 1 Carrying box (brown skai) If necessary a complete manual set on CD/DVD It is a complete set for who wants to start with the HP-85. I acquired the HP-85 a few weeks ago checked it and converted the tape drive to QIC40/80 replaced the printer timing belts and some elco's. The computer is clean but a bit yellowed, the HP 9121 drive is cleaned and all hardened grease is removed so it is fully functional. I'm open for offers, the items are located in the Netherlands but I ship worldwide, local pickup is also possible. I'm not doing this to get big money but I want to earn a little to acquire other HP-stuff for my collection and find it fun to restore old HP equipment.

Imaging a TK50 across the network

by sander.reiche＠gmail.com

Hi all, It is probably asked before, but I can't seem to find it in the archives. I have a MicroPDP up & running 2.11BSD but no spare TK50 tapes to make a backup of it, before I f*ck it all up :) I do have a lot of TK50s which weren't mine and they have data on it of which I do not know the status. They came with a MV3100 with VMS on it, which I am going to use eventually as well. So I'm not really willing to just scrap the data on those tapes. I'd like to make a backup-image of those across the LAN before I write anything else on it. How do you guys usually do it? # tcopy /dev/rmt0 to see what's on it # dd if=/dev/rmt0 bs=??? | rsh other_current_bsdmachine_with_lots_of_diskspace -l <user> dd of=vms_tape_file?.img bs=??? for every file on there? I didn't even know `dd' wouldn't cross EOF boundaries tbh (wasted my youth on C64s and Amigas :)). -- ~ UNIX is basically a simple operating system, ? ? ? ? ? ?but you have to be a genius to understand its simplicity. ~ dmr

CP/M: How to use old dischette?

by elazzerini＠interfree.it

Hi all, The reason why I'm interested in this topic is that I recently restored a Ferguson Bigboard I with its CP/M 60K. I'd like to try different programs that are contained in third parts diskettes, but they are of course in a different formats. I am using ANADISK to identify the format and sequence of sectors on disks and 22disk133 to try to read them correctly. Despite having read the definitions of the FCB manual on CP / M, I am finding difficulty in : 1) to determine the block size chosen for different disks; 2) Identify the value AL0 Unfortunately it seems that any further calculation is dependent on the size of the block that would seem a prior undetectable, and i'd need to try different values (starting from 1024,2048,4096 and 8192). Is it in this way? Some format i'd like to determinate: A xerox SWP diskette: SSDD 9,1024 sectors sequence 1,2,3,4,5,6,7,8,9 A MK-83 diskette: DSDD 8,1024 sectors sequence 1,4,7,2,5,8,3,6 Thanks for any helpful hint.

Tandata TD1100 dialer

by ard＠p850ug1.demon.co.uk

It took me a lot of work to discover this information, and I am not sure why it's so cryptic. But anyway... Some time ago I mentioned I had a Tandata TD1100 viewdata set on the bench. At power-on you get a dialing menu, the numbers for which are clearly stored in the battery-backed RAM. Dialing a number from the menu was easy (<menu number>#, for example 2#). But I could not find out how to stroe numbers in the menu, everything I tried got 'Please Try Again'. I am not suprised I didn't find the right sequesnce by trial and error. It is clearly designed to be impossible to get by accident. I fianlly found it by readign otu the firmware ROM (it is socketed, but I can assure you that desolderign a 24 pin DIL chip would have been trivial compared to the rest of it), writing a quick-and-dirty disassmbler for 6502 code (soemthing that took me most of yesterday (Newtonsday) afternoon [1]), and then going through the lisitng. [1] This would ahev been a lot easier if the 6502 data sheet I'd been workign from handn't been written by a boatie. There's a nice 16*16 table of the nmemonics, the rows and columns being numbered from 0-F. It turns out that the _rows_ are the most significant nybble, in other words you read it across, not down. The lables indicating this are in tiny type in one corner, and I missed them. So I had to move my table of mnemonics aroudn a bit. ARGH! My first guess, which turned out to be correct, is that it would use CMP instructions to identify wheter a typed character was 'acceptable' or not. So I searched the listing for these, and found a sequence of CMPs which seemed to do the right thing. I then spent some time figuring out what that routine does, and I finally got the sequence to load a number into the dialer menu. It is : Turn on 'program mode' with the switch on the back first and type : <menu position>*****<Number to dial># For exxaple 2*****123456# will store 123456 into the second position of the menu. Note that it's 5 '*'s. No fewer (or you get an error), no more (or you get spaces at the start of the number in the menu. If you do not turn on program mode, the entry is ignroed -- no error message. -tony

Hitachi: NAS 9060 ? Various S/370 emulators All of the information that follows is included in the tar.gz archives available at Bitsavers.org. The D6.0 documentation has also been combined in a single PDF that is available on the MTS Archive at: http://archive.michigan-terminal-system.org/documentation/documents/MTSD6Do… Among other things the file D6.0-MTS-DOC.txt from April 1987 (a year prior to the release of D6.0) says: MTS is currently being run on the following computing systems: Amdahl 5860, 5870, 470V/8, IBM 3090-400 (with vector facility), 3081G, 3081D, 3033N, and 4361. In addition MTS has been tested on or was used for production on the following machines: Amdahl 470V/6, 470V/7, 5890, IBM 3033U, 370/148, 370/168, 370/158, 4341, and NAS 9060, and XL. The same file goes on to say: Machine Requirements MTS requires an IBM 370 compatible machine (including the 30xx machines) with at least two megabytes of memory and the following features: Floating Point Universal Instruction Set CPU-timer and Clock-Comparator Translation with 1M segments and 4K pages Conditional-Swapping PSW-Key-Handling Channel Indirect Addressing on all channels Clear I/O on all channels It will make use of the following features if they are available: Extended precision floating point Vector facility Direct control (limited use) Branch and Save Fast release on channels Invalidate Page Table Entry Common Segment Facility Other features are not used, unless user programs make use of them. The MTS file system normally uses IBM 3330 and/or 3350 compatible disks in any combination although it also supports older types of disks. MTS also provides support for the Xerox 9700 page printer, the Autologic APS-5 phototypesetter, and for both IBM and ANSI standard magnetic tape labeling/blocking and the normal IBM unit record equipment. >From D6.0-NEWSYS.txt: 1. The starter system requires a minimum of one 3270 terminal, one 3380 disk drive, and one 9-track tape drive. >From the D6.0-NOTES.txt: MTS can run under the 370 and 370-XA architectures. Under 370-XA, each task is limited to an address space of sixteen megabytes, but all real storage on the machine will be used to support virtual storage. MTS does not (yet) run run under IBM's ESA-370 architecture. MTS provides Named Address spaces, a facility similar to IBM's Discontiguous Saved Segment support under VM, to allow tasks to share preloaded programs and data. A program may be loaded into a Named Address Space (or NAS) at system IPL-time and then added to or deleted from a task's virtual storage as needed. MTS will use expanded storage as a high-speed cache to minimize I/O to DASDI. The cache is store-through; all writes go immediately to disk. However, disk reads will be satisfied from the cache if possible, thereby cutting down the number of real disk I operations required. Changed DASDI [in D6.0] to use "Read Device Characteristics" command to determine the size of the disk being formated. This gives us support for any disk supporting this command including: 3380s (Ds and Es have been tested; Js and Ks should work but have never been tested) CMS minidisks (untested) The old FBA disk support has been rejuvenated. MTS now supports internal 9370 disks (9335s have been tested; we have not tested 9332 support).

Broken Amiga keyboard

by eivinde＠terraplane.org

I have an Amiga keyboard (pcb says A3000) where the four keys 1, q, a and z doesn't work. The rest of the keyboard functions well. This happened after a longer period where I didn't use the keyboard. Does anybody have any ideas of things to check out to try to get this working again? Regards Eivind

Tons of manual and literature from the 1960s+ in Irvine, CA

by tosteve＠yahoo.com

Hundreds of computer manuals and literature from the 1960s mostly, the golden age of the minicomputer. Most in excellent condition - many probably never opened. Located in Irvine, CA (Orange County) Includes Univac, HP, lots of minicomputer time-share. No list of contents available - there's more literature than manuals. See a few pictures here. http://oldcomputers.net/temp/manuals1.jpg http://oldcomputers.net/temp/manuals3.jpg http://oldcomputers.net/temp/manuals4.jpg http://oldcomputers.net/temp/manuals5.jpg http://oldcomputers.net/temp/manuals6.jpg http://oldcomputers.net/temp/manuals2.jpg Last photo is misleading - only about 12 boxes contain this material.

Here's a summary of what I have been able to cull together so far: (1) The Z80 BOOT PROM code (version 1.2 at least, which is the source listing I have) appears to probe the Winchester, for boot e.g. - try to read Winchester - check result - if error, try floppy - if OK, check Winchester label - if bad label, try floppy - if good label load system and boot??? (this part is unclear to me) (2) Not all of the v1050 CP/M BIOS versions appear to support the Winchester. Versions up to 1.1 do not appear to contain the WINCH.ASM module which I am assuming is required for support. I do not have access to version 1.2, but I see this module showing up starting in version 1.3. I would assume that with the 1.2 BOOT PROM and the 1.4 CP/M BIOS I could support the Winchester (barring any bugginess - Bill I believe you have v2.0 of the CP/M BIOS and not sure on the BOOT PROM). What isn't clear to me at this point is how to install CP/M onto the Winchester and get the label setup so that the PROM would boot directly from the hard drive.

HP color crt oscilloscopes

is anyone knowledgeable enough of their product line to give me (us) a rundown of these models, and characteristics (roughly) since their inception (1989 AFAIK). I'm in the market for one, probably an older model, any condition, but not too shabby w/regards to sampling rate (let's say starting at 100mhz, they may not have gone any lower anyway).

rl02 and other disks from ebay

by jzg22＠drexel.edu

If anyone bought any of those rl02 or other dec or classic disk packs and media from ebay, please PLEASE read the contents out before overwriting them! I recently found a bunch of lost unix v5-era source code on erased space on an image of a disk pack image from dennis ritchie, archived unknowingly at tuhs, so who knows what other gems may be on those disks in erased space? dump them with dd, not with dump, since dump ignores or zeroes out blank space. Tar obviously ignores blank space as well. -- Jonathan Gevaryahu jzg22 at drexel.edu

recreating C source from binary

by lehmann＠ans-netz.de

Hi, I'm trying to re-create the source files for the Z8000 UNIX I have on my Z8000 system (it is a S8000+ZEUS clone). Easy programs like sync.c where easy. But when argc/argv is involved, I'm not able to generate 1:1 matching binary code. I'm working on /etc/unlink for now. I tried the following C file: char whatstr[] = "@[$]unlink.c 2.1 07/23/82 21:19:30 - 87wega3.2"; main(argc, argv) int argc; char **argv; { if(argc!=2) { write(2, "Usage: /etc/unlink name\n", 24); exit(1); } unlink(argv[1]); exit(0); } The original ASM code for the beginning of main() until the argc check is: 0042 abf3 dec r15,#4 0044 5df60000 ldl %0000(r15),rr6 0048 0b070002 cp r7,#%0002 The ASM code my C file generates is: 0042 abf3 dec r15,#4 0044 1df6 ldl @r15,rr6 0046 0b070002 cp r7,#%0002 keep in mine, that r15 is considered as the "stack pointer". I wonder how to get the ldl from the original binary. I also tried to declare argv with "char *argv[]" which resulted in the same code. Forcing the compiler to store argv into a register by using the "register" keyword results in completly different code: (sp = stack pointer = r15) #17 adb unlink ADB: P8000 1.6 ? 0x0042/i %0042: dec sp,#6 ? %0044: ld %0004(sp),r14 ? %0048: ld %0002(sp),r7 ? %004c: ld r14,r6 ? %004e: cp r7,#%0002 ? $q #18 Maybe the C compiler used to compile /etc/unlink differs from the C compiler shipped with the system (maybe an older version) but I don't want this to be true for now ;) Anyone with deeper ASM and C knowledge than me sees what could be done here? Before someone asks - yes I'm sure the source file was in C and not ASM based on the whatstr. Symboltable of the original /etc/unlink is empty as well (striped binary). Regards, Oliver

They are probably perfectly good for photometric applications too, where it doesn't matter if it takes some time for the cell to adjust to the illumination. And as far as environmental issues are concerned, it would certainly be much better to get rid of CFLs. There has actually been some coverage in the news here about CFLs being thrown in glass recycling containers instead of being handed in as toxic waste (there are reasonably easily accessible places that accept toxic waste everyhere here as well, but nowhere near as many or as accessible as glass recycling containers) and causing problems at the recycling plants. LED lighting is being promoted instead. So far, there has been no discussion about environmental issues with semiconductor manufacturing... /Jonas

CdS cells have quite a few problems that have made them obsolete for photographic purposes: temperature dependence, slow response and memory effect. They need a significant time to adjust to a different level of illumination to give a normal response. The response becoming non-linear with age has also been reported. For a long time cameras have been using silicon photodiodes instead. As an example of the memory effect, the manual for a Durst darkroom exposure meter, which I have just been given and which uses a CdS cell, says to illuminate the CdS cell immediately beneath the lens of the enlarger for 15-20 seconds before making a measurement. They do work well all the same, most of my cameras that actually have an exposure meter use CdS cells. And they seem to be easily available. /Jonas

Classic Picture

by dj.taylor4＠verizon.net

I was looking on ebay at pictures of Balltimore. Lo and behold I saw something the Classic Computer folks would appreciate. See ebay item 260916992297 It is a picture of an actor, but who cares, it's the background that caught my eye.

wanted: raised flooring for cheap

by legalize＠xmission.com

I figure there are three classes of "cheap" for raised flooring systems: - it's new and on sale - it's used and removed/reclaimed from a decomissioned data center/machine room - it's used and sitting in the existing machine room and you come pull it out so they don't have to deal with it Ideally I'd like to pick up something for free, because this is not a high priority item for the museum. It's more in the "nice to have" category. It would make it much easier to supply power to exhibits in the middle of a large open area because I could run power and data cabling under the floor. -- "The Direct3D Graphics Pipeline" -- DirectX 9 version available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

FS. PDP 11/35 + RK05 units in Yorkshire

by silvercreekvalley＠yahoo.com

I'm thinking of thinning down my PDP 11 collection a bit and have a nice PDP 11/35 unit which may be of interest. This is a collection only item in Yorkshire. This is in good condition and fully functional. It is fitted with the max memory 128KW I think, and the MMU. I also have the incredibly rare FPU for this unit, but its not fitted or tested. Also available with the unit, three RK05 drives with disks, cables and the driver cards (which are fitted to the 11/35). Other spares, parts available too including a spare CPU set (minus the MMU and FPU). This is a very tidy unit and as I say its fully functional, powers up cleanly, and even has its original key. Fitted with a UK plug (European voltage) and can be powered from regular mains. Email if interested. Sorry no postage on these units, I cant even lift them never mind post them :)

Hello. I have a nice DG One portable computer; it's the 2T version, and appears to be fully working. I doesn't have however manuals nor original OS disks for it, so I'm asking if someone has something to share. It would be very interesting to find also copies of the CPM OS disks. Thanks Andrea

Automatic file associations - Re: Unix handles file extensions "very poorly"? - Re: Mac/Mac Programming/Cocoa/HyperTalk

What is so terribly wrong with using the file's _name_ to describe the type of data a file represents, so that those "humans" that you seem to disdain elsewhere can also know and work with its type, not just the computer? Always sad to see that in a community one would expect to be eager and open to explore different and perhaps even better ways of doing things, this sort of discussion so often is mostly just defending the status quo and _arguing_ over DOS *versus* UNIX, Win vs. Linux, Apple vs. PC etc., even sometimes to the point of insulting and name-calling, not to mention the all-pervasive disdain and contempt for those unwashed [L]users 'out there' whom all this is ultimately actually for and who indirectly pay most of our salaries. We are all in the same business/hobby after all and surely there are better ways to spend our precious time... But alas, it has ever been thus... BTW, I think this quote from Ritchie himself sums it up perfectly: "Unix is simple. It just takes a genius to understand its simplicity." m

ISO: Binary editor with bit shift/complement, etc.

by cclist＠sydex.com

I'm looking for a binary editor (platform doesn't really matter) that can take blocks of bytes (or bits), shift them right (extended shift, carrying bits throughout the entire block, not just shifting things on a byte or word basis), XOR, AND, OR with a repeated value (i.e. 12 means 12 12 12 ...), modulo add or subtract, etc. Anyone know of such a thing? Most binary editors I've seen are very weak in the area of binary data manipulation. --Chuck

Good reference: AN-43: http://cds.linear.com/docs/Application%20Note/an43f.pdf I'm sure Jim Williams thought it was worth it and I really enjoyed reading about it so it was worth it to me for sure :-) A highlight was Note 5: "What else should be expected when trying to replace a single light bulb with a bunch of electronic components? I can hear Figure 39?s #327 lamp laughing." I had previously met Sir Denys Wilkinson and he had mentioned something to me about his pioneering days in nuclear instrumentation (including pinball machine multichannel analyzers). When he had told me that he had invented the D/A converter I didn't really believe him but kinda nodded along. Then I read it in Jim Williams' application note - with an actual reference - I felt a little sheepish in retrospect! Tim.

Tandy Videotex and Office Information System

Hi All. sorry about the quoting - only just re-enabled emails from the list; pasting this out of the web archive: Back in October Kelly Leavitt wrote: >>>In July of 1983 Tandy announced the "Tandy Videotex and Office Information System" that ran under Xenix. It was an early attempt at a hypertext system. It used dialup lines and was hosted on Tandy Model 16b (and later 6000) computers. An 8 port and 16 port multiplexor (that's how they spelled it) were announced. I don't know if either ever shipped. There is some information available in the July 25, 1983 issue of InfoWorld. There is also an article in "TRS-80 Microcomputer News" V5,I 11 (#54 ). I used to run one of these for a local company (that I still work for).

Looking for powerpc and decent graphics card for Apple Quadra 950

by silvercreekvalley＠yahoo.com

I'm dusting off my Quadra 950 and thought it might be good to try and upgrade it a bit if I can. I have a fairly slow TrueColour graphics card installed at the moment, so I'm looking for a better quality/faster NuBus card. I'd also like to put in a PowerPC upgrade if I can find one. I used to have one of these years ago, and it used to work pretty well. The Quadra has a PDS type slot. Anyway - anything considered. I'm in the UK - but shipping this weight of item from overseas wouldnt be too much I think. Contact me off list if you have anything. Thanks Ian. :)

H200 series ID?

I looked at the wikipedia entry for the Honeywell H200 series today, and when I came to the "Pupular Culture" section I remembered that when I was in High School (and our Computer Club got to use my school district's H1200 stand alone one night every week) Lily Tomlin did a "We don't care, we don't have to, we're the phone company" bit that I could swear included an H200 series system. I found the video at: http://vimeo.com/16175616 http://www.movieweb.com/tv/TEbXhcfhdjEkec/HUOVvPTWha0QSW It still looks like a Honeywell to me. Can any one make a solid identifcation of what model? http://snltranscripts.jt.org/76/76aphonecompany.phtml says the skit aired 9/18/76. H200's were over ten years old at the time.. That's 5 computer generations these days! The wikipedia page has some H200 photos: http://en.wikipedia.org/wiki/Honeywell_200 And more at: http://www.feb-patrimoine.com/PROJET/honeywell200/h-200.htm http://starringthecomputer.com/computer.php?c=48 says H200's appeared in several movies, including the original Casino Royale!

Solaris Sparc ZFS sun4u to sun4v migration

by jjacocks＠mac.com

Has anyone successfully migrated a ZFS-hosted Solaris 10 sparc host >from one arch (sun4u) to another (sun4v)? I have found all kinds of docs on how to do it, if your source is UFS-rooted, but nothing, if you're ZFS-rooted. This seems like a _huge_ oversight, to me, but I lost my faith in Oracle, a long time ago. I've tried: 1) root pool regeneration from "zfs send -r" snapshot backups 2) flar/jumpstart (add sun4v arch to flar, when creating) 3) liveupgrade 4) ldomp2v tool None of these have been successful. The closest that I have gotten was by doing a ZFS root pool restore, on the new host, and then manually installing the ".v" versions of all of the missing packages. That got the system booting, but there were a _lot_ of broken libraries. Any help would be greatly appreciated. Thanks! - Alex

Microcode on Floppy for MV-2000dc Mod II

by jtpinch-treiff＠usa.net

Hello, We have a MV-2000 Mod II that we still use to manage our business. As time goes by, more and more of our tapes (DC-1000 21mb cartridges) are failing. I do have a copy of microcode (ver 10) from tape that has been saved to a hard drive as a disk image. As tapes fail, I've been able to make "new" copies, but I'm running out of tape cartridges. Would anyone know where I could find microcode for our MV-2000 mod II on 5.25 floppies? Our MV has an internal 5.25 (720kb) diskette dive that could load microcode at boot time. I've already tried copying the tape image to floppy, but it appears not to be enough. I'm guessing DG organized microcode on floppy a little differently then on tape. Does anyone have any ideas?? Thanks for your time. Tom jtpinch-treiff at usa.net

"first" computer on the internet

by dgahling＠hotmail.com

I thought I had posted this, perhaps not. Anyhow, I have what's purported to be the "First" computer on the internet, the one that joined the pieces together and I guess you could say "made" the internet, or conversely, the "last" node, as it were (depending how you count). It's also the system where E-Mail was first created. It's a Sun SLC workstation, owned by Einar Steffard. I have the original box (very slightly torn), and the workstation itself is in very good shape except one cosmetic crack, which I believe can be fixed very easily. I tried the smithsonian, and other computer museums, but basically was told they already had too many of this model, never mind the significance of this particular unit. it still runs, last I checked, and has all the original data still intact on it, such as it is. now, I find myself with a severe lack of space, and need to part with it. I would like a little bit of money for it, it wasn't a donation to me, and shipping maybe expensive. or I would be willing to trade it for a vaxstation 4000, or perhaps a 3100 or two. (I have a need for 2 working vaxen you see) so anyhow, that's how it is, this piece of history sitting in the corner of my office, collecting dust, and not doing much else. I'd like to see it get to a good home, and never scrapped, I think it's too important for that. so anyhow, anyone who wants this piece of history, drop me a note. and yes, I have pics (including the shipping labels from Einar to me) for what it's worth...

LC475 and EDO RAM

by fraveydank＠gmail.com

Here's a rather esoteric question that I suspect at least one person may be able to answer better than the collective urban legendry found on Google. I have a Mac LC475 (same machine as Quadra 605), and I'm looking to max out the memory. None of Apple's tech notes mention anything about EDO memory, and people tend to generally think that it can handle it, but I've been bitten before. Does anyone have a good idea about whether the memory controller can handle it? Also whether it can actually take advantage of it? My gut feeling is yes to the first and no to the second. Secondly, does anyone have experience with Micro Memory Bank? They seem to be offloading piles of newly-manufactured vintage-compatible (5V FPM and EDO) DIMMs and SIMMs on Ebay. The collective common wisdom for the LC475 is that 128MB SIMMs will work, but only if they're single-ranked. The salespeople for the vendor don't seem to know what I'm talking about when I ask, and I'm having a hard time getting photos of the board from them (which should at least let me look at the traces). Anyone know about their 128 MB EDO/FPM SIMMs? Relevant auction number is 350478815002. - Dave

S-100 CPU board PCBs

by LYNCHAJ＠YAHOO.COM

Hi! I have some excess S-100 8086 CPU board PCBs. These are leftover from the recent S100computers.com and N8VEM group buy. They are $20 each plus $3 shipping in the US and $6 elsewhere. Please send a PayPal to LYNCHAJ at YAHOO.COM and I will send your boards right away. Build and test of these boards has verified they work and the hardware is correct although there is a minor top silkscreen error. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=S-100%208086%2 0CPU%20board> &param=S-100%208086%20CPU%20board http://s100computers.com/My%20System%20Pages/8086%20Board/8086%20CPU%20Board .htm Also, if you are interested in an S-100 6502 CPU board, I am getting ready to make a PCB manufacturing order. So far there are 17 boards for builders signed up and I need another 3 to make it economical. Please contact me if interested. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=S-100%206502%2 0CPU%20board> &param=S-100%206502%20CPU%20board Thanks and have a nice day! Andrew Lynch PS, there are some remaining S-100 Serial IO and S-100 buffered prototyping board PCBs left too.

TV -> D-Sub converter possible?

by alhartman＠yahoo.com

Listen fellows... I worked for two of the major hardware/software suppliers for the Radio Shack Color Computers. I have 10 of them in the next room, as well as a Tano Dragon 64k. A stock Color Computer or Color Computer 2 has no Composite output. It only has an RF Modulator that tunes to channels 3 or 4 VHF (U.S. Models, I have no experience with other versions). You cannot GET a composite signal without cracking the case and soldering a few wires to a simple circuit to clean up the signal. Several companies sold a tiny board with a few components that provided composite video and standard audio for use with a regular composite monitor (Mark Data Products, Dennis Bathory Kitsz, and a few others. I liked the MDP product best as it used little spring loaded clips and was basically solderless.). You can easily build one with parts in your junk box, or maybe $5 in parts from a local Radio Shack. I will track down the schematic and find a way to post it. The next best solution is the idea of using a VHS Player to capture the RF signal and convert it to Composite internally. There are several Coco Emulators that one could just use on a PC and bypass the whole thing. Jeff Vavasour's (?http://www.vavasour.ca/jeff/trs80.html#coco2?) is supposed to be one of the best. I really like the Coco system, and I wish I had room to set one of mine up. I co-wrote The Coco Greeting Card Designer, which was similar to the greeting card version of Print Shop. I have the rights to sell the follow-on, The Coco Graphics Designer which has all the different things with a Mac-like GUI frontend. I just need to make the manuals up and duplicate the disks from my master copies. I also have the rights to the Car Sign Designer on the IBM-PC (DOS), C-64, and Coco. I have the disks, manuals, and car sign holders but need a working C-64 to test the disks. I got a c64 AND 1541 in trade, but the 1541 doesn't work and I haven't fixed it yet. Al

well-written, concise man pages

From: Josh Dersch Sent: Tuesday, December 13, 2011 9:08 PM > I just wish UNIX man pages were as well written and as > all-encompassing as the online documentation available on my > Lisp machine.

CPU Wars card game

by pontus＠update.uu.se

Hi all I just found this little card game which looks kind of neat: http://www.kickstarter.com/projects/harrymylo/cpu-wars-volume-10-the-card-g… Quite x86 centric, I think the J11 would fit pretty nicely in there. What CPU would you add? /P

cctalk Digest, Vol 100, Issue 34

by alhartman＠yahoo.com

Ok, I dug up the schematic. This is for the Video Only. You'll have to get a copy of the Coco Schematics to find out where to tap the audio (Probably at the input to the RF Modulator, but I don' t know what you'd have to do to make it sound good)... http://img190.imageshack.us/img190/8801/23fa5940.gif (The "New Board" mentioned in the GIF means the Coco 2 logic board) Here is a link to a repository that has the service manuals: http://goyim.dyndns.org:8080/coco/Documents/Manuals/Hardware/ That's the best I can do now, as my Cocos are on a top shelf I can't reach anymore and can't pull one down to look at the installed adapter. Hope this helps. Al

last call for AT & T 7300 UNIX PC docs

by chrism3667＠yahoo.com

big box but cheap via media mail. Philip expressed interest in the tech manual. I'll joyfully send it to him if he still wants it. Let me know Phillip. I'll just chuck the rest I guess. Have the Wordstar manual/s too, but no disks.

At one time I was given the task of evaluating the optimum location for a knock sensor. I had an engine fitted with a number of knock sensors in various locations on a dynamometer test bench, and a device connected to the ignition which allowed me to advance the ignition from TDC in increments of a few degrees. This thing was provided as an official test device from a large US manufacturer, I have forgotten which one - RCA? GE? GM? It was built with CMOS 4000-series ICs IIRC, and constructed on - solderless plugboard... Changing the amount of ignition advance was done by moving a wire between different holes in the plugboard. Using this kind of thing in an engine test cell, with an engine running under heavy load close by and me standing next to it, struck me as rather shaky to say the least. Especially as a bad connection, or plugging the wire in the wrong hole, could make the engine produce "interesting" noises. Had something serious happened to the engine there might well have suddenly been large parts of metal flying around and plenty of hot oil and water spraying about. It did actually work OK though. /Jonas
