I don't think I missed the beginning, and there was nothing about Woz, Cap'n Crunch, etc. It started off with a camera following some PHB through security checkpoints. It was mostly hype, glorifying the "white hats" like Internet Security Systems (www.iss.net) and making their NOC look like the next best thing to 007 and Q. Their handling of the "black hats" wasn't as shrill or alarmist as I'd have expected after the first bit covering ISS' NOC and "AlertCon." The production value was high - they used lots of flashy visual gimickry to let you know how cool this topic and the production team is/was. Didn't do squat for content, but someone had fun inverting color maps, solarizing and posterizing images, making lots of jump cuts, etc. But don't worry, they harped on the potential for an "electronic Pearl Harbor" quite a bit. They had a very touching bit about how the top-level hackers cherish their anonymity because, when they achieve underworld fame, they would be harassed by the hordes of wannabees and ankle-biters... I felt so sorry for them. :^/ I really disliked how they lumped Eric Raymond, John Perry Barlow, and the EFF in as somehow defending these "black hats" and their desire to commit real, traditional crime. They did let ESR get in a couple words expressing the difference between cracker and hacker, but I wouldn't expect my mother to have understood it and they quickly moved on. And then they made his guest accomodations, described as they walked into his office, sound like a stop on some sort of hacker underground railroad... The worst part? They had a guy from the MPAA on describing piracy, and the response from the other side was clearly aimed at the strategy of using DRM to gain control of the desktop by Hollywood. But they didn't explain that they were presenting responses to two different issues, so it looked like the EFF was somehow trying to support people ripping off movies before they're released to the theater. Not good. There's a nutshell review. My opinions, YMMV. --Steve.

Enterprise customers kinda laugh at the idea of their stuff being of the "Intel Inside" kind, and will be almost impossible to be changed into that. They'll go Sun, or IBM, but will do pretty much anything to NOT be sucked into this "New Big PC crap", as one of them called it. In the old days, we had Sun, DEC, Compaq, HP and IBM for the larger systems. DEC got sucked into Compaq, which also had Tandem. That seemed like not such a bad plan, and it could have worked (my personal opinion.) Now, we loose both DEC/Compaq (so, Tru64/Alpha and VMS/Alpha) and HP (HPUX/HPPA), only to get... _MORE_ Intel crap into this world. Don't get me wrong- I like my PC's. And yes, some of them run Win2000, some do UNIX, whatever. But that's *PC* stuff, for PC tasks. My customers will probably invite me in to come and tell them which vendor of "real" Big Things (tm) they can switch to now, without the chance of having to do that again in two years from now. So... Sun (sigh) or IBM (eek) ? HP loses.. bigtime. And as a shareholder.. indeed, i voted 'no' :) #define NHP /*brainless*/ #define HP NHP --fred

Tubes in computers - numbers, please

by aw288＠osfn.org

There is a large quantity of tubes for sale near me, and while it is silly to think I can buy and store them all, I might be interested in buying quantities of *computer-rated* tubes - things like 5749s, 5814As, 6414s, and so forth. Some day, maybe a 709 will come my way with 1000 empty sockets... Anyway, if any of you folks have information or samples of old tube based computing junk (modules, for example, or old unit-record stuff) - could I bother you to tell me what types of tubes were originally installed? I am looking for specific numbers, not just "dual triodes". It would be nice to know which machines used which tubes - for example: Machine Tube(s) Used ----------------------------------- IBM 604 1684, 2032 Thanks a bunch! William Donzelli aw288(a)osfn.org

free Wang 6540-1 and Fortune 32:16 systems in the Chicago area

by uban＠ubanproductions.com

A friend of mine is cleaning house and has the following two systems available for free pickup in the Chicago area: CPU: Wang model 6540-1 with Wang hard drive model number 6580, Magenetic Peripherials Inc, Control Data corp., Model number 9448 Cartridge Drive, Part No. 77717013 http://64.32.210.122/picts/Computer/Wang/index.html (condition unknown) Fortune 32:16 http://64.32.210.122/picts/Computer/Fortune/index.html Condition: the hard drive does not spin up. Last time I tried to power it up, it displayed: 1 2 3 and then hangs (probably because of the hard drive.) I think it used to count to 10 as it boots. If you are interested in one or both of these, please send email to: Bill (jackbot AT yahoo DOT com) be sure to replace the AT and DOT accordingly. --tom

Catweasel Floppy Read/Write Tools, version 3.0

by tim＠tim-mann.org

Version 3.0 of my Catweasel Floppy Read/Write Tools is now available at http://www.tim-mann.org/trs80resources.html. This release adds support for the new Catweasel MK3 PCI card. The older Catweasel MK1 ISA is still supported as well. Standard blurb on the tools: The Catweasel Floppy Read/Write Tools are software for the Catweasel universal floppy disk controller. The tools run on both Linux and Windows 95 or MS-DOS. Source code is included under the GPL. cw2dmk will read several kinds of floppy disk, some of which ordinary PC controllers have trouble with, and save them in the DMK disk image format. (DMK is a format used by the Unix TRS-80 emulator xtrs and by David Keil's TRS-80 emulator for MS-DOS.) cw2dmk does not just read TRS-80 disks; it can handle (at least) any disk written using a Western Digital 177x/179x floppy disk controller, a PC-style NEC765-compatible controller, or a Digital Equipment Corporation RX02 controller. dmk2cw will write any DMK image back to a real floppy disk, and handles the same kinds of disks as cw2dmk. The package also includes the programs dmk2jv3 and jv2dmk, which convert between the DMK image format and the JV1 and JV3 image formats. These programs work without a Catweasel and can be useful for moving images between different TRS-80 emulators. -- Tim Mann tim(a)tim-mann.org http://www.tim-mann.org/

Need information on TRSDOS 1.3 internals

by foo＠siconic.com

Does anyone have any documentation on the data structures of TRSDOS 1.3? Specifically, I'd like to know the catalog structure, as well as the scheme for storing files across multiple sectors. I'm trying to pull some old word processor and perhaps spreadsheet files off some TRSDOS disks using a PC. I already found a utility called READDISK that reads TRS-80 disks on a PC and it worked great. Now I need to extract the files from the image. Is this data published in any of the TRS-80 DOS manuals?

Acquired a PDP11/44, but missing M7095

by glenslick＠hotmail.com

A google search for M7095 turned up www.jtcomputer.com so I already sent an email earlier tonight inquiring about a M7095. Are they a decent place to do business with? I just tried an old barrel key from a Kryptonite lock and it does work (a little rough to insert & remove) so that takes care of that problem. I didn't get any disk subsystems. The rules of the surplus department where I aquired the CPU dictate that disk drives be destroyed before systems are made available to the public. The I/O cards that were installed were an M7521 DELUA ethernet, CMD CDU-720/TM SCSI, M7819 DZ11-A octal serial, Digital Pathways TCU-150 clock module?, M7258 LP11, Datasystems DLP-11. The CPU came in a rack that is about three times the height of the the PDP11/44 and about 1.25x as wide. It's a Digital rack, but I didn't see a model number on the rack. The rack itself really heavy. They used a forklift to load it into my van and I was able to get it out of the van myself with the careful application of gravity, but there was no way I would have been able to get it into the house. I did download the User's Guide / System Technical Manuals which came in handy when I got stuck trying to figure out how to release the rack slide lock mechanism. Now I've got the CPU out of the rack and in the house were I can work on it. The rack did have bulkhead connectors and cables for the M7521 DELUA ethernet (AUI) and the console (DB25). The rack had a couple of other connectors I didn't recognize, I think they must have been cabled up to the M7819 DZ11-A and M7258 LP11. There is no breakout pod for the M7819 DZ11-A. The DLP-11 had a very long LPT ribbon cable attached. It might have originally been attached to a huge Genicom? printer that was also available at the surplus place, but I passed on that at the time. I inspected the insides before thinking about trying to power up the CPU and when I realized the M7095 was missing (I wonder why it was removed?) I didn't go any further. Also, while the power supply is configured for 120VAC it has the high current (20A) plug with one of the lugs rotated 90 degress and I don't think I have any compatible outlets in my house so that is yet another challege to solve. If I do get the CPU running, then I'll have to figure out what software I should try to run on it. I don't really know much about PDP11 software yet. -Glen >From: John Lawson <jpl15(a)panix.com> >Reply-To: cctalk(a)classiccmp.org >To: cctalk(a)classiccmp.org >Subject: Re: Acquired a PDP11/44, but missing M7095 >Date: Wed, 11 Dec 2002 01:58:00 -0500 (EST) > > > >On Tue, 10 Dec 2002, Glen S wrote: > > > I recently acquired a surplus PDP11/44 (my first real PDP11) and it >appears > > that it is in reasonably good condition, but after opening it up to >check > > out what modules were installed I realized that it is missing the M7095 > > control logic module, one of the 5 core modules that make up CPU. >Anyone > > know where I can find one of these at a reasonable price, or have a good > > spare that they care part with? > > Congratulations!

PDP11/44 system mains current

by jpl15＠panix.com

As a working example: I have an 11/44, FPP, 2MW, 2 DZ11, RLV11, Dilog ESDI card. 1 RL02 2 5 1/4" ESDI drives in a PDP11/23 chassis of all things. All this is in an H960 with the usuall DEC power control box... all of it plugs into an outlet in my dini^H^H^H^H machine room, which is on a 15 A breaker... I have yet to amprobe it, but if it's more than 8A at 120 I'd be quite surprised. Now, when I get the Kennedy 9100 and another RL02 hooked up, and an LA36.... sigh. it never ends.

BBC Acorn

by rigdonj＠cfl.rr.com

Today I went and picked up another part of my lot of computers that I bought last week. One of the things that I brought home today was a BBC Acorn computer. I'd heard of these but never seen one before. I was pleasantly surprised to find that this one was apparently built for use in the US and that it operates from 110 VAC 50 or 60 Hz and has a US style power plug. Does anyone know how many of these were imported into the US? I'm assuming that since it's set up for US power system that it will also operate on standard US TV and monitor frequencies. Does anyone know for sure. BTW the model number on this one is UNB 09. All the Acorn websites that I've found only list models A, B and B+ so I'm not sure what this is equivelent to. Joe

Acquired a PDP11/44, but missing M7095

by glenslick＠hotmail.com

I recently acquired a surplus PDP11/44 (my first real PDP11) and it appears that it is in reasonably good condition, but after opening it up to check out what modules were installed I realized that it is missing the M7095 control logic module, one of the 5 core modules that make up CPU. Anyone know where I can find one of these at a reasonable price, or have a good spare that they care part with? Also, the keyswitch for the front panel is missing. Anyone know where I can find one of those, or is there an easy way to bypass the switch? On the plus side a CMD CDU-720/TM SCSI controller was installed so if I get the CPU running I hope it won't be too hard to connect it to a SCSI hard drive and tape drive. _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963

RL02 Disk Cartridge Problems

by cmcnabb＠4mcnabb.net

I just received an RL02K-DC disk cartridge that I won on Ebay. It looks the same as all my other cartridges, and the shock indicator is still white. When I put the cartridge in either of my drives, it spins up for a while then the fault light comes on. This does not happen with any of the other RL02 cartridges I have. I can see no difference between this cartridge and any of the others, and it seems to take no less force to turn by hand. I'm wondering what I could be missing. Any help would be greatly appreciated. -- Christopher L McNabb Operating Systems Analyst Email: cmcnabb(a)4mcnabb.net Virginia Tech ICBM: 37.1356N 80.4272N GMRS: WPSR255 ARS: N2UX Grid Sq: EM97SD

It will fault if it can't find the servo signals, though. Actually, the *drive* just moves a number of tracks back and forth. (And seek is just to a relative track). When you progam a driver to seek to a track, you check the current track, calculate the track delta, and request that of the drive. When the drive report ready you once again check the track to see which one you actually are on. Hopefully it is the right, but if not, do another seek. However, when you *read* a sector, the *controller* checks that you read the right sector by checking every sector header that the head passes over, and when the right one comes, the data is transferred (the same applies for write). If the right sector don't show up, it will fail, but I don't think it will fault. > > It seems to me that to correctly format one of these disks after a bulk > > erasure, you would have to be able to do the following: > > 1.

That's just (relatively slow) digital electronics. Correctly position the heads when you don't have a servo track, and the heads are actuated by voice coils, means you cannot position the heads at all. So that is a big hurdle.

You don't have any half-track spacings. However, you also need to write the guard bands, which are outside the normal data area. But if you happen to have a drive you can move the heads about with absolute precision (well, pretty good precision anyway), and being able to write headers, I doubt writing the guard bands would be that hard. You just have to know how the guard bands look physically. The drive recognoze them, and immediately move back to the data area if they show up.

KIMplement for the C64

by spectre＠stockholm.ptloma.edu

I've threatened to do it and so I did. This is The Incredible KIMplement, a partial emulation of the KIM-1, entirely in software, for the stock Commodore 64. http://www.floodgap.com/retrobits/kim-1/ This isn't a joke. It has a full software 6502 core, which works by distilling opcodes down into "safe" equivalents and running those natively to reduce the work it has to do. All memory access is trapped and abstracted. The 6502-on-6502 core is machine-independent and hopefully I can use it to do tricks like virtual memory, protected memory and interruptable/restartable instructions. The emulator includes LED emulation, 6502 emulation (NMOS documented instructions only), SST emulation, keypad emulation, and even supports an emulated TTY. No interval timers yet, but I'm working on it (the ROMs have been trapped so they don't need them). Revision E ROMs are built-in. Hope no one still asserts the rights ... Thanks to Jim Butterfield and Peter Jennings, I've also included Lunar Lander, Addition, Key Train, Sort (all from First Book of KIM) and the original Microchess as a separate download. Beware of Microchess; on the emulator running on a stock C64 in Normal mode, it will take about 30 minutes to compute a move! :-) In the future, I want to use that software core to make a proper OS for the C64 (or Commodore One). The 6502 has gone too long without a proper MMU.

Acquired a PDP11/44, but missing M7095

by glenslick＠hotmail.com

The CPU has the 14 slot main backplane and a 9 slot expansion backplane, connected together with the M9202 jumper card pair. When I first opened the top the M9202 jumper card was plugged into slots 12 and 14 of the main backplane. I assume it is really supposed to plug into slot 14 of the main backplane and slot 1 of the expansion backplane to bridge the two so I moved it there. The M9302 terminator was in slot 9 of the expansion backplane. I believe all row D connectors except the empty 10,11,12 memory slots either had a card installed or had a stubby little card grant card installed. I didn't pull any of them to see what they were (G727, G7270, G7273?) > BTW - how many slots / backplanes are curently installed? How many free >slots? How many BUs Grant cards are in open slots?

Well, at least it's not one of those nasty Antex 15W irons, but I prefer a 50W temperature-controlled iron. The risk with a small iron is that the tip cools down as you put it on the work, and the lower-wattage irons can't heat it up very quickly again.

HN462532G - same as TMS2532?

by philpem＠dsl.pipex.com

Hi, I've just bid on some Hitachi HN462532G EPROMs on Ebay - item numbers 1943283712 1943523215 and 1943750626 (I've bid on the first two - feel free to outbid me, just leave me with at least one pack of three). Can someone please confirm that these are pin-compatible with the TI TMS2532? I found a pinout on R. Steve Walz's webpage (www.armory.com/~rstevew), but I'd like confirmation from someone who's attempted to use the Hitachi chips as replacements for the TIs. Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

The effects of employment

by jss＠subatomix.com

Well, I can officially stop complaining. I've just scored a software engineering position with a local natural gas production company. This will have three effects with respect to the ClassicCmp list: * I will no longer gripe about lack of funds in nearly every post. :-) * My collection will experience growth and an increase in quality, which hopefully will enable me to do things like software and documentation archiving, hardware testing and restoration, and of course, playing with shiny new toys. * You should see me start to offer free stuff to list members soon. Yes, today is a good day. -- Jeffrey Sharp

One more screwup with the Ace...

by dwightk.elvey＠amd.com

Wow! I think we've all had a wack at poor Phil. Hi Phil I think the most important thing is to save the board over saving parts. If you think you've lifted a trace that is a thru hole( and these are two sided boards ), take a piece of wire wrap wire through the hole and solder it to the topside of the board and it goes through the hole. Don't solder it in the hole. Make sure that the component lead will fit through. When you put the part in, fold the piece of wire down so even if you heat it enough to melt the solder on the top, it won't rotate. If the top trace is clearly visible with the lead in there, you can solder the lead from the top. Use an Ohm meter to verify that you've made connections to all the right places. Dwight

One more screwup with the Ace...

by philpem＠dsl.pipex.com

Hi all, Well, it looks like I've finally destroyed the Ace. I've just spent the past hour trying to desolder the dead RAMs and buffers from the Ace's main PCB. Unfortunately it looks like the board was designed to self-destruct when anyone tried to repair it. The pads appear to have been designed to peel off on the application of heat, they're less than 5 mils around the hole (what do you think that means?) and they don't even seem to be through-hole plated. The tin plating was applied straight on top of oxidised copper - I've had to retin some pads and tracks courtesy of that major screwup. In my opinion, the Jupiter Ace is one of the most appallingly-made machines I've ever tried to repair. Heck, the Commodore 64 was bad, but at least the pads were easy enough to desolder. It looks to me like Jupiter Cantab's PCB designer was either *VERY* inexperienced or just wanted to make sure that no-one could fix an Ace if it failed. It's also beginning to look like the ROMs are stuffed, but that shouldn't be too hard to sort out -- I've just bid on some 2532 EPROMs on eBay from someone in Austria. Does anyone know how I could rescue this machine? It looks like the RAMs are definetly fried, along with some of the logic as well. Font RAM and Video RAM are still not being loaded on startup so the output of the video generator is still 100% noise, however it *is* changing when the machine is powered off and then back on again. I'm shotgunning all the RAMs (there's only six of them) and the bus muxes. Has anyone here either repaired one of these machines or got a spare Ace to sell me? I've got a proper PSU now, with only one connector (the jack plug the Ace uses), so I can say with near absolute certainty that the same mistake will not occur again. Later. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

One more screwup with the Ace...

by doug_jackson＠citadel.com.au

I totally agree. Remember the concept of the $99 computer. You dont sell a computer for $99 if it costs you $150. I suspect that commercially, the cost breakdown probably went something like this: $99.00 Final RRP (Margin + Freight + Wholesale price) $30.00 Sales Margin (30%) $ 5.00 Distribution freight $65.00 Wholesale price $65.00 Wholesale price (Margin + freight + Sinclair sell price) $ 9.75 Wholesale Margin (15%) $ 2.00 Wholesale freight $53.25 Sinclair Sell Price $53.25 Sinclair Sell price (Manufacture cost + R&D Recovery + Sinclair Margin) $10.65 Sinclair Margin (20%) $10.65 R&D Recovery (20%) $31.95 Manufacture cost $31.95 Manufacture Cost (System + Plugpack + Lead + Manual Printing) $16.00 Component Parts $ 1.35 Membrane Keyboard $ 3.00 Modulator $ 1.60 Case $ 3.00 Plug Pack $ 1.00 Video Cables $ 1.00 PCB $ 2.00 Assembly Charges $ 2.00 Manual Printing $ 1.00 Packaging (foam etc) These figures have been fudged to fit, but you can see that at $99 there is basically *no* rooe to provide any type of quality.

One more screwup with the Ace...

by dwightk.elvey＠amd.com

Hi Phil If you know a part is bad and you want to remove it >from the bard with the least damage, clip the leads close to the part and then remove the leads, individually, with a pair of tweezers/iron. Always use a temperature controlled iron set to the point that a clean tip will melt the solder of the joint in about 10 to 15 seconds. Even really cheap PC board can be reworked if one uses some care in methods. I don't recommend using solder wick. Many do well with it but it tends to get stuck to traces if not overly heated and will lift traces. If you use a solder sucker, don't use a small one. Use one with as big a bore and stroke as you can find. Dwight >From: "Philip Pemberton" <philpem(a)dsl.pipex.com> >Hi all, > Well, it looks like I've finally destroyed the Ace.

help: HP r/332 controller

by rigdonj＠cfl.rr.com

I just found one of these in a load of scrap. It appears to be similar to the HP 9000 200 and 300 series computers and uses the same DIO cards but also has a built in CRT and floppy and hard disk drives. It's designed to be rack mounted and it's supposed to have a fold down keybaord but the keyboard is missing on this one. Fortunately the unit uses a HP-HIL keyboard socket so I can plus in a regular HP_HIL keyboard. Has anyone here used one of these? Are they supposed to show a list of installed memory and interfaces when they power up like the 9000 200s do? I'm not getting any display on the CRT but I can see the sweep and retraace lines on the CRT when I turn the brightness all the way up so the CRT is working. The hard drive light illuminates for several seconds then the floppy drive accesses for a split second so the system seems to be working but still don't get any display on the screen. Joe

Most silicon IC's can take a lot of heat applied slowly. Thermal shock making a large range of temperature change is real rough on them and more likely to fracture the IC or cause the lead seals to fail. > >> and if necessary that you can repair any damaged >> tracks with stripped wirewrap wire or similar. >None of the tracks are stuffed, the pads seem to have come up because the >solder wick stuck to them and pulled them up, even though the wick was still >heated. This is why I never recommend using solder wick unless you are vary experienced at desoldering. You need to know the right size and the right touch of applying the heat with this material. I do 95% of my desoldering with a sucker and only the last special cases with wick. I have three different sizes of wick to select for each job. I use different heat ranges as well. > >> How adept are you >> with a soldering iron? >Six years of experience, three with a Maplin elcheapo, three with my Antex >XS25 (25 watt).

UYK-40 vs UYQ-70 Shipboard computers

by jpl15＠panix.com

In doing a bit of inquiry as to the desireability of the various surplus UYK40 and 44 computers, I found that the K-40s are all being replaced as fast as possible by the current UYQ-70 system, made by Lockheed Martin in Minnesota. You can check out this system at: www.q70.com quite a fascinating look at what the next generation's collectible surplus looks like today. Cheers John

386 Motherboards available

by cb＠mythtech.net

I have a few 386 motherboards here that I want to get rid of. They are free for the taking, or I will ship them to anywhere if you cover the costs. All are as is, but should have been working when removed from service. I have the following: - AMD 386 SX-40, AMI Bios, "Cyclone" chipset?, 6- 16 bit ISA slots, 4- 30 pin SIMM slots. This board is smaller than normal boards. It measures 8.5 x 6.75 inches. - AMD 386 SX/SXL-25, AMI bios, VLSI chipset?, 7- 16 bit ISA slots, 8- 30 pin SIMM slots. Underside has a part number MB-1316/20/25VST. - Intel 386 SX-20, AMI Bios. "Chips" chipset?, 6- 16 bit & 2- 8 bit ISA slots, 8- 30 pin SIMM slots. This board is larger than normal, 13 x 8.75 inches. This is from a WYSE PC, and has some custome WYSE chips in it. Also looks like the AMI bios may be a custom WYSE job (at least it carries a WYSE part number). I don't know for sure if this one can be brought back up to working. It might have needed some ISA cards with it (which I don't know where they are, but I know I had some WYSE ISA cards for things like the drive controllers). 2- AMD 386 SX/SXL-25, AMI Bios, Opti chipset?, 6- 16 bit & 2- 8 bit ISA slots, 4- 30 pin SIMM slots. If anyone wants any of these, or parts from them, let me know. There are no math co-processors on them (but all 5 do have sockets for them). The WYSE board has what may be socketed cache chips (OKI, M514256A-80R, and OKI M51C256-80). -chris <http://www.mythtech.net>

Looking for N* parts

by RCini＠congressfinancial.com

Hello, all: I'm working with Scott LaBombard to get my N* system (which is mostly made up of Vector parts) working. This has been an on-and-off project of mine for years, but I enlisted Scott's help since I can't seem to make it work. After slogging through all the parts, re-configuring everything, and doing some testing, we've found that I need either a N* single-density boot disk or an MDS-AD/AD2/AD3 double-density controller. It seems that when I got this machine a few years ago, the person must have had multiple N* systems and sent me only double-density disks (common) for a single-density (more rare) equipped system. Can someone help me out with this? Does anyone have a spare N* DD controller? Thanks in advance. We're pretty close on this one. Rich

new acquisition: an 11/73 running RSX-11 v4.6 and a question on cihper tapes & CDC SMD disks/controllers

by spector＠zeitgeist.com

I just got a new acquisition -- a PDP11/73 (born an 11/23 plus but upgraded) -- up and running. Its running RSX-11 v4.6 and I found a useful tidbit which may come in handy to others since I had no info on accounts on this machine and have limited experience with RSX-11 (I was a RSTS, UNIX and VMS guy wrt machines of this era): As it booted, several well-timed ^C's as tasks were being installed got me to an MCR> prompt where I could run $ACNT and make myself an account so I could log in. Re: making accounts, it was a trip to see the "depth" of account info and security on the machine. :-) Its an interesting little machine: M8192 PDP-11/73 processor M8043 DJV11-J 4-port async M3104 8-port async Emulex HD controller (not SMD) -- model not (yet) known Emulatex tape controller (ibid) for Cipher 3200/1600 bpi 9track tape drive 512KW memory (no name or number on board -- only a sticker that says "made in hong kong") M7504 DEQNA Cipher model M890340-96-1050U tape drive KPV-1180 Parallel Line Printer Controller Printronix P6000 ~400lpm line printer (biiig data center cabinet .. dot matrix, circa-1985) It has some flavor of winchester that looks to the OS like an RA81 (but is a 5/25" HDA -- I haven't disassembled every part of the rack yet). Also in its low-boy case are two CDC SMD "Fixed Storage Disks" disks (27"+ deep, > 50 lbs, SMD interface) for which I have an empty slot but no controller for. The model # on the disks is: 72859381. Does anyone have any ideas on these disks and what kind of controller would bring these CDC disks back to life..? (anyone got controllers to trade? I have all sorts of goodies...) Als, any online pointers to maint manuals for the tape drive..? regards, David ------------------------------------------------------------------------ - David HM Spector spector(a)zeitgeist.com software architecture - network/security consultation technical due diligence - technology planning/analysis Office:(631)261-5013 Cell: (631)431-5756

AN/ UYK-20X(V) a different aspect:

by xds_sigma7＠hotmail.com

As for who would still be needing -20's, my money is on NATO (and non-NATO) countries who have purchased older warships from us. Just because the US government doesn't need them does not mean that no other goverments need them.

OpenVMS VAX hobbysit CD

by Qstieee＠aol.com

To quote from http://www.montagar.com/hobbyist/mount.html "OpenVMS Hobbyist CD Media The OpenVMS Hobbyist Kit V2.0 is currently available. You must be a member of a participating DECUS/Encompass Chapter before you can order an OpenVMS Hobbyist Kit. You can order the kits on-line via our web site, or via mail order. At this time, OpenVMS VAX media kits are sold out. If you are still interested in getting OpenVMS for your VAX, you may try borrowing a CD from a friend, co-worker, local Encompass LUG, Ebay, or other places. Please note that any OpenVMS distribution is legal to use with the Hobbyist Program (as long as it's not stolen!)." Does anyone have one or know an FTP site? If one can get real DEC VMS CD's will the hobbyist license PAKs work or do you need the hobbyist CD?

The Blue Wall! or Intel strikes again!

by rigdonj＠cfl.rr.com

Take a look at this <http://home.cfl.rr.com/rigdon14/mds800-3/blue-w~1.jpg> I went scrounging Thrusday and went to my favorite scrap yard. I knew I was in trouble as soon as I drove into the place! Everywhere I looked I saw blue. Intel blue! I don't even know how many I bought. I've made two trips bringing it back so far I estimate that over 60% is is still there! The stuff in the picture is PART of what I've brought home so far. The LH stack has a MDS-230 and MDS-225, In front of that is an iUUP EPROM programmer and two MDS keybaords. The next stack has an OLD Intel terminal and a MDS-225. The third stack has a MDS-230, a Mostek dual 8" floppy drive box and an Intel DDR external 8" floppy drive box. On the right is a homebrewed S-100. In front is a SWEAT MDS-800. As you might have guessed from the picture, this stuff is sitting outside. The OL says that I HAVE to clean the house out before Christmas. I have another DDR drive chassis and a big stack of loose Multibus cards inside the house. I found the Multibus cards in a basket of cards that were going to be ground up for the gold scrap. I still at least two more MDS-2??s, a MDS-800, another Intel terminal, several external drive chassis AND (drum roll, please) a dish washer sized Intel external hard drive to pick up. For you heathins, there was also a huge pile of other classic computers. I bought a BBC Acorn, a home brewed S-100 crate, two Morrow external 8" floppy drives, a so far unidentified STD-Bus computer, five new Shugart SA-1004 8" hard drives, AT LEAST 20 Shugart 8" floppy drives, a Wicat computer, four different and FUNKY programmers panels, a rack mount dual 8" floppy drive box made by Mostek, a old but clean Centronics printer, a loaded Cromemco Z-2D, an Osborne OCC-1, a nice 80 TPI 5 1/4" floppy drive in an external case and a mass of other stuff that I can't even remember! I left behind a huge pile of Xerox 820s including external floppy and hard drives, an unidentified Xerox computer that's wider than the 820, a Multibus computer chassis made by Advanced MicroComputers (I think they're a subsidary of AMD) I later found the cards for the AMC computer in the pile of Multibus cards that I dug out of the gold scrap bin so I may go back and get it. Also left behind a GenRad 2300 Advanced Developement System with it's external dual 8" floppy drives and an external expansion chanssis. I wasn't sure what it was but later fround that it's a CPM system. Looks interesting but probably hopeless trying to find docs and SW. To top it all off as I was leaving Friday (trip 2) I went over to see the guy that they have stripping everything. I looked at what he was doing and he was busily gutting a drum memory!!! I looked around and found another that he had already torn one apart and I found there was one more to go. I wasn't intersted in it at the time but now I'm wondering if I should have gotten it. He said it weighed over 140 pounds! It looked like a 1/2 scale v-8 engine! That's all for now, back to cleaning, sorting and packing! Joe

Can anyone provide me with links to information on IBM printers manufactured between 1981 and 1986? I'm especially interested in pictures of the printers themselves. Thanks, Jeff
