Hello Tony, I am having a little problem finding info for this part and I found you comment on the internet that you have the databook. I am doing a small repair that calls out for ZN448E-8 but I only found info on ZN448E. Are these the same part? Any information is much appreciated. Regards, Andrew

HP 2000 BASIC help / TREK73

by micheladam＠theedge.ca

Hi. Nice to know these listings have been found. The game brings back fond memories. The 2000 was the first mini I programmed on, in college. I have read all the replies, and no one has suggested what I am about to suggest, so here it is: In order to do a really good job of sanity checking, it would help if we could see the listings to compare with what has-been/wil l-be typed. People will want to port it to other close version of basic (hp-eloquen ce) or BASICV on the 3000, and a typo is always a problem with languages that dont necessarily declare variables before assigning things to it. So, if you had a way of scanning the listings and making them available on your web site, that would be a boon to everyone. Assuming the listings are in good enough shape to scan. As well, you could then spread to work around! Just my 2 cents worth...

HP 2000 BASIC help / TREK73

by pete＠dunnington.u-net.com

I need some help with some HP 2000 BASIC. I probably last used it around 1980, and not often even then for somehow the PDP-8s looked more attractive than the grey HP box in the same room. Yeah, I know better now. Luckily, I'm sure some of you can help me out... I've been retyping TREK73 from a fairly poor-quality listing, and it needs a sanity check. Also I'd like to learn a bit more about what I'm typing. This is the original source for the Star Trek program by William Char and friends, and what I've typed so far is on my Star Trek web page at http://www.dunnington.u-net.com/public/startrek/ I've added some other stuff to that page, too. Questions: All the lines have two spaces between the line number and the code. All, that is, except for a few that have an '@' in place of the second space. Is that significant (does it mean "ignore this" or something?) or is it just an artifact of a noisy Teletype line? (The listing appears to have been made on a Teletype, which needed a new ribbon and a better platen roller.) What does '14 in a PRINT statement, in front of a quoted string, mean (eg in PRINT '14"SULU")? I wondered if it were something like PRINT TAB(14)"... but there are TAB()s elsewhere. A control character, perhaps? If cursor or screen control, are they octal or decimal (I'd guess decimal) and is there a table anywhere? What exactly do the first two parameters to the ENTER command do? They always seem to have three variables (eg ENTER T2,T,X$). That'll do for now :-) If anyone would like to proofread what I've retyped so far (about half the total) and check for obvious sillies, please do - especially in TREK0 around line 740 (cf line 840). Better still, if anyone is willing to actually try this out, please do! though it won't work very well with half of it missing. -- Pete Peter Turnbull Network Manager University of York

more Press stuff.

by witchy＠binarydinosaurs.co.uk

Well, I hope that didn't turn out too bad. The article is actually about market values of Sinclair machines and things like the Black Watch and will be in the Financial Times in a couple of saturdays. I basically spent an hour deriding ebay and emphasising the historical side of collecting for exhibition and educational purposes, not financial. Apparently I'm not the only one he's spoken to that thinks that, though there's also been others who've said stupid things like 'turn up with a non-yellowed zx80 and I'll give you ?400 for it' We both agreed that it was highly unlikely you WOULD get ?400 if you did that. The journalist is speaking to a lot more people and at present he's on the fence between telling people to sell their MK14s now and telling people to hold onto them. Naturally I told him to tell people to give things like that to me :o) The current ebay situation with Zebra ZX81 kits is a good example of how greed can go wrong...... On a sort of unrelated note it's idiot week on ebay again - a battered looking yellowed ZX80 is currently at ?155 despite it only having the bottom sorry looking poly, PSU and manual.....many days left to go, too.

NEC MULTISPEED HD

Robert, I read your entry on some bulliten board about your NEC MULTISPEED HD. I just recently acquired one and it runs fine, just not sure if the backup battery works. For now Im running it with the original NEC a/c power pack. The only "problem" that I can find is at the startup it says "bad or missing /dd.bin" but other than that all directories on the hard drive are accessible and floppy drive works fine (even though its only a 720kb 3 1/2") If your interested in this computer, make me an offer and we can work something out.

need some info on some sort of pocket terminal

by dhofstetter＠triad.rr.com

Hey, how you doing.. I was doing a search for TM990 for work and came across your message. I work on that antique stuff you have come across. TI had two calculator type programmers. These units were used with the 5TI sequencers and PM550 PLC's. This stuff is still being used in industry for controlling machines. I've had to refurbish a couple of the larger calculator type programmers last year. They are a polled RS232 device that only talks when told to by the PLC / Sequencer. http://www.datamath.org/ This is where i got the pictures... There is some thrill rebuilding these things hooking them up and punching in some ladder logic and watching the flashing lights on the I/O racks.. Some of the stuff you pick up may still bring a decent price on ebay.. Even this old seemingly antique stuff..

What is an M750 "Line I/O control" for?

by v.slyngstad＠verizon.net

I asked this in alt.sys.pdp8, but didn't get the answer, so I will try here: When I got my PDP-8/i (oh so many years ago), it came with a supply of flip-chip spares. Among them are 24 M750s, which I can't find any info about, except the phrase "Line I/O Control". What are they for? They aren't for any of the 8/i's built-in options, so there must be an external option that calls for them? Is there a reason for me to keep so many of the things? Thanks! Vince

Try: http://www.hp-eloquence.com/download/ The package is mainly for a re-implementation of the HP3000 IMAGE database on different platforms, but it started life when HP discontinued the HP 250s years ago, and it includes a version of BASIC that is probably closest to the 2000 ACCESS, other than BASIC V on the 3000s. The latest version has departed from using line numbers, but I think version 6 still fully support a line-number mode for the basic language. If not, you may have to go back to version 5.

>Apple? Old stuff? Hahaha. I'd be surprised if they still have last >month's Macintosh model sitting in some back closet somewhere. Actually, Apple has a testing lab that has a pretty wide range of old Macs running assorted mac OS versions. Its even free to use if you are an Apple Developer. The catch is, its in Cupertino, and you have to do the testing yourself, so unless you are local, or have a good budget, its tough to use. Poor shareware developers like me have to depend on our own collection of old macs (of which I just liquidated 95% of my own). -chris <http://www.mythtech.net>

PDP-8/L not incrementing properly

by sebastian.brueckner＠epost.de

Hi! I once again tried to get my PDP-8/L to run this weekend. Unfortunately I am not not yet a PDP professional - I don't have a clue what most of the modules are doing. I started to read the Maintenance Manuals but I do not quite know where to start. Maybe you can give me a hint: I tried the "simpler" instructions like set accumulator, or accumulator with switch reg. etc. What I did not yet try are the different jump instructions. I will be more specific as soon as I tried more instructions. CLA and STA work, i can set all bits in AC. IAC (increment) and all the rotate instructions however always set AC to 1 completely ignoring the previous value. Where should I start looking for the problem?

Another Computer in a Movie

by bmachacek＠pcisys.net

Does anyone remember the name of the movie that came out in the mid 60s that had a CDC 3600 (I think) as a background in part of it. I had a friend who told me he was the CDC rep during the shooting of the movie, but it's been so long ago I've forgotten the name of it. He said all he had to do was go in each morning and bring the system up and make sure all the lights were flashing, that was the important thing about it. It was definitely a CDC computer, since my friend worked at CDC, but I am not real sure about the model. It was, of course a sci-fi movie.... Thanks for any help and there are movies other than TRON.

Getting ROOT on Indy (last question!)

by nemesis-lists＠icequake.net

Also, if the indy has accounts with login allowed (like guest, lp, etc), and no shadow passwords, you can log in as one of those accounts, grab the password hash for root from /etc/passwd, and crack it on another machine. I got into a IRIX 6.2 box this way. IRIX 6.5 I believe uses shadow passwords by default so you might be out of luck there for an "easy" solution. -- Ryan Underwood, <nemesis(a)icequake.net>

Getting ROOT on Indy (last question!)

by owen＠bardstown.com

OK, my Indy is now (almost) all working. I need to change the monitor refresh rate, but I can't do that unless I can log in. I don't have the root pwd either. Apparently you can't go to single user without the root pwd. I can do just about anything -- I have a serial console hookup, but no root to go with it :( I can't get it on a network either... I tried using the setenv command to set the IP to a local address, but I don't think it works (new to IRIX/SGI, so that may be way off!) Anyone have any ideas? I already tried most of the normal ones -- guest, tours, lp, etc. and found them to be closed! Jeez, just what I need... a security consious admin! I have no floppy or CDROM installed on this, nor do I have a SCSI adapter to mount the drives under linux and do the deed the _simple_ way. I also lack IRIX media. Any thoughts? I don't want to buy many more components... but I guess that if I have to, I can make a few more purchases... Thanks! Owen

TRON electronic game and *old* batteries...

Next time I visit my parents I will be pulling my TRON electronic game out of storage... It looks like a mini arcade machine and had three or four games. Now the question: What causes batteries to start leaking? I am worried that there may have (now) 15 year old batteries in it. :( Cheers, Bryan

Hello Arlen, I am a consulting engineer working with a client up in Sacramento, CA that has a Model AA-545 development system (S/N 5129 CEI) used to program a Motorola MC68HC05C8 microprocessor back in the late 1980's. We are also interested in learning more about this system and if there is someone out there who could use it... We do have some 5 1/4 in floppy's (MS -DOS 2.0) for the system. Did you ever find any further information during your search in July? Perhaps we can in some way help eachother?

help identifying S100 board

by ian_primus＠yahoo.com

I recently acquired this board, it appears to be an S100 board, since it has the 100 pin connector and voltage regulators onboard. Does anyone know what this is, or what it came from? In the upper right corner, it says "Dynatech NEWSTAR 1MP481 REV. A (C) 1990" The board has a Z80, a 27128 EPROM, an 8k static RAM, some 41c256 DRAMS, a Z80 SIO, some RS-232 line driver pairs (1488/1489), and two 26 pin headers, which appear to be serial ports. Here is a picture I took: http://24.194.65.231/images/unknownboard.jpg It appears to be a complete Z80 computer on a board, so I would imagine that it would be possible to power it up, and connect a terminal to it, but I don't know if it would do anything. Any information on what this could be, or what it might do would be appreciated. Thanks! Ian Primus ian_primus(a)yahoo.com

Heath H-89 & Magnolia Disk Controller

by patrick＠evocative.com

I'm trying to get a Magnolia floppy controller running in an H89, and I'm having some odd problems. The Magnolia controller apparently requires their own monitor ROM, which I have (444-84B revision 10). It's my understanding that this ROM actually negotiates the baud rate with the terminal logic board rather than requiring a fixed 9600 as the Heath ROMs do. However, when I have this ROM installed, the machine doesn't seem to be able to "sync". The CPU and TLB speak together perfectly with the normal Heath ROM (444-84 or 444-142), so I'm inclined to rule out problems with the UARTs, transceivers, and cables. But most of the time the screen spouts gibberish with the Magnolia ROM in place, and when it does sync up, I can't type more than a few characters before things go to pot. I've also gotten the same behavior with two known-good CPU boards. Any suggestions? Does anyone know if revision 10 is a good version of Magnolia's ROM, or do I have it because the guy I got it from uses version 11 in his '89? :-) This controller supports a variety of 5-1/4" formats, as well as 8" drives, so I'd love to get it running. Thanks! Patrick P.S. Yes, I do have the "other" recommended Magnolia PROMs in place... full set is 444-83 (Heath), 444-61 (Heath) and 444-66B (Magnolia). --P

HP disk drive alignment stuff

by jwest＠classiccmp.org

I just got a kit off ebay (Item # 3056408822) that is pretty much a complete kit for working on HP 7905/06 type drives. Thing even includes an air pressure guage :) However, I actually HAVE most of the parts in this kit already, most of the boards and the DSU. However, my DSU has most of it's switches broken off and hasn't yet been tested. This also means I now have two alignment packs, two extenders, etc. etc. As a result I'll be taking my partial kit to ebay to recoup the costs of this complete kit. If anyone here is interested, let me know within a few days and we can work out a trade or something before I go the ebay route. Jay West --- [This E-mail scanned for viruses by Declude Virus]

They are of birds or other animals that a cat would normally chase. Its not as if they are watching Matlock reruns or anything. These are videos of small animals flying or running around the screen.

Tape backup drives available

by cb＠mythtech.net

I have some old tape backup drives I'm getting rid of. I know some of you do data conversion services, so if one of you that does that wants one (or all), they can be had for the cost of shipping. I have a Maynard 150 MB drive plus 14 tapes, a few connecting cables and some ISA and MCA interface cards. This is an external drive, with manual and software (complete setup). Also an Iomega Tape 250 drive and a stack of tapes (not sure the number, but about a dozen or more). This is an internal drive, manual, cables, software are with it. And a Colorado 250 drive. No tapes. External drive, no cables, software, manuals or power supply. And an unknown internal tape drive. All the front says is "250 MB", so its obviously a 250 MB drive. I don't know who makes it or anything else about it. There are no obvious markings on it to determine who makes it. I have no tapes for it, or software or manuals. There is a cable attached to it, looks like it plugs inline into the floppy controller. Also I have a cassette tape drive. Its a TEAC something in an external SCSI case. Uses 120 MB cassette tapes IIRC. I was never able to find the correct tapes for it. I do have a box of the wrong tapes however. Like I said, these are all available for cost of shipping. Preference will go to someone that will use them for data conversion or recovery services (or anything else that directly supports classic computers). But anyone that wants them can ask for them... I'd rather they go to someone instead of the dumpster. -chris <http://www.mythtech.net>

Motorola MVME 68K boot file sys5.3 ?

by g-wright＠worldnet.att.net

Hi, All I just tried to boot my Motorola s8000 which has a 68030 and SCSI controller. All are Motorola Mvme cards . The system lost the boot path. ??? If I use BO 2,0 it finds the IPL loader but needs the file name to boot. I can't seem to guess the right name. Is there a way to interface with the IPL or a way to read the boot path directory. I have no manuals on this or OS tapes. I would also like to find any of the manuals and OS tapes for this. It has a MVME141 processor, and a MVME327 SCSI card. I don't really remember the UNIX version I believe it was 5.3. This has 4 SCSI drives and only the 2,0 finds the IPL loader. - Jerry

One More 13w3 Question!

by owen＠bardstown.com

Good(ish) news! I plugged in the 13w3 adapter to my Indy, and then a good Sony Trinitron monitor -- and it WORKS! Well... the opening screen does. After that the monitor goes black. I tried it on a random noname monitor from 1992 -- after the "Stop for Maintenance" prompt goes off screen, all the video gets very garbled very fast. Is this an adapter problem? Since I have two monitors here that seem to support sync on green, can I make this work? Thanks! Owen -- Owen Marshall BISI Systems Administration / Tech Support (502)349-9444 x106

One of my Indys has been used with a lot of different monitors since I bought it in 1995; it's currently using an SGI monitor which only uses the SOG, but previously had a monitor which didn't support SOG. Several of my friends bought reconditioned Indigos from SGI and bought standard VGA monitors with them. I don't know if the Personal Iris or Crimson provide separate syncs (some other 4D series do -- that's why they have more than 3 BNCs), but the later machines do -- and the original question was about an Indy (which does). -- Pete Peter Turnbull Network Manager University of York

8080 processor adaptor module?

by rigdonj＠cfl.rr.com

I recently bought a Fluke 9010 test pod. With it, I got a model 210-9080 8080 Processor Adaptor Module made by Wildwood of Phoenix Arizone. This is a pod similar to the Fluke pods. It has a wide ribbon cable coming out of it that terminates in a 40 pin DIP plug presumably to plug into a CPU socket. On the box is a ZIP socket (for the CPU?). It also has a double row of 40 pins that appear to be test points. On the other end of the box is a 20 pin ribbon cable with a ribbon cable socket on the end of it. Does anyone know what this is for or anything about Wildwood? Joe

Maybe it a > question of what > sync types your monitor supports. Suns use different pins for sync than SGIs (and Suns usually use composite sync, while SGI use separate H and V), and SGIs also use some pins for monitor type sensing. However, quite a lot of Suns and most SGIs also provide sync-on-green, so if the monitor supports that, and the other signals don't cause confusion, it should work. Contrary to popular belief, most SGIs from the Indigo onwards do not require a SOG monitor. Sorry, I don't know what the pinouts are for HPs or IBMs (apart from R,G, and B).

SGI Indy 13w3 question

by owen＠bardstown.com

I just bought a rad Indy from EBay. It seems to start up fine, as shown by the rockin' startup music! However... I can't get video... I have a 13w3 --> VGA adapter that was supposed to work with it. The light on the Indy goes green but my NEC Multisync monitor stays red. I tried the adapter on my IBM POWERstation and saw the NEC monitor turn amber. Any thoughts? -o

SGI Indy 13w3 question

by lbickley＠bickleywest.com

You'll have to look at your monitor's documentation. Most high-end monitors are capable of sync-on-green - most inexpensive monitors do not support it. There are adapters that "attempt" to create standard sync signals from the sync-on-green, but I've had mixed results (at best) with them. Your best bet is to pick up a nice sgi monitor (20"). Depending on where you live, you'll find them modest in price and if they are working properly, they have outstanding color, etc. Lyle On Friday 07 November 2003 19:06, you wrote: > Ohboy.

PDP-11/44 want list

by will_kranz＠SoftHome.net

John On Tue Oct 8 20:11:58 2002, you posted about your 11/44. I was searching for help with the H7140 power supply when I came across your post. I recently tried to power up a system I got a couple years ago, and have a flashing 'DC On' indicator. I don't know how serious this is, or if I might be able to repair/adjust it with some guidance. Suggestions? I have no documentation on the power supply. Thanks.

Friden Flexowriter interface timing signals

by tomj＠wps.com

I'm making a Friden Flexowriter simulator to bring up my LGP-21 (solid-state follow-on to the LGP-30). I do not have access to the LGP-21 Flexowriter, which is modified from a "standard" (sic) flexo in a number of ways (peculiar code set, special fromt-panel switches). I have hardware documentation for the LGP, which includes a fair chunk of Flexo data (schematic, etc) but it's not much help with the interface timing. I think it's likely the signal names are standard (sic) Friden, but I don't know. (The simulator will be PIC-based, and will diddle the interface signals under control of host-resident software, to which it'll talk to via serial port.) I'm assuming it's a "busy/done" system, eg. to print, the computer sets up print data (before point a, below) then asserts the strobe or gate on (at a). (call it Print Start, or interface "busy"). When the Flexo has assimilated the data, it asserts Print End, or "done", at b, which clears Print Start; when Print End deasserts, at c, the interface is ready to begin the next cycle: a b c +---------+ | | to flexo START -----------+ +--------------- +----------+ | | >from flexo END ---------------------+ +---- I believe receive is similar, with the directions reverse of course. Specifically, I can't determine the timing relationships of signals: (print) Tx print start? JL29 print end? (receive) Xs receive start? Sr receive end? JL12 "start input cycle" JL11 "end of flex input cycle" Receive especially bugs me, since it appears to be two sets of handshake that do the same thing. The descriptions in "quotes" are from the LGP-21 algebraic descriptions of the Flex interface. (There are also signals JL32, JL33, JL28-20, and LGP-specific Friden switches "START COMPUTE", and maybe "MANUAL INPUT", which the LGP sees in some manner.) Here's the Flexowriter cable end pinouts, if it's any help. Flexowriter connector (JL) P38, end of cable to J19. to/from flexo 01 TP5 to Print data 02 TP4 to Print data 03 TP3 to Print data 04 TP2 to Print data 05 TP1 to Print data 06 TP6 to Print data 07 Tx to Print start ("busy") 08 -60V from 09 Sr to Receive end ("done") 10 /BQ from Manual input 11 JL11 from "End of flex input cycle"? 12 JL12 from "Start input cycle" 13 P5* from Receive data 14 /P5* from Receive data 15 P4* from Receive data 16 /P4* from Receive data 17 P3* from Receive data 18 /P3* from Receive data 19 P2* from Receive data 20 /P2* from Receive data 21 P1* from Receive data 22 /P1* from Receive data 23 P6* from Receive data 24 /P6* from Receive data 25 SIGNAL GROUND 26 27 Xs from Receive start ("busy") 28 JL28-20 to 29 JL29 from Print end ("done") 30 31 SIGNAL GROUND 32 JL32 to 33 JL33 from "translator cam"? 34 SIGNAL GROUND 35 117AC to 36 117AC to 37 CHASSIS GROUND

Hi, not that I want to go hunting on your turf :-) but I need to buy a lot of older untested RZ28 and RZ29 disks (hundreds) for cheap. So I have contacted the places I know of and may get perhaps half of what I need from one. So I need more addresses where I can ask. The focus is on computer-junkyard and not so much reseller becasue I want to buy untested possibly failed equipment. thanks four your hints, -Gunther

Not quite 10 years old? Digital Alpha PC64 parts...

by dwoyciesjes＠comcast.net

Well, I'm finally getting around to building up my Digital Alpha PC64/275MHz box. Only problem is I have no L2 cache SIMMs, so it won't boot up at the moment. Plus, I still have to rewire my ATX power supply for it. Got the mother board connectors from a dead donor Aspen Alpine box :) Tried a regular AT power supply on the PC64, but since there is no cache, no go... Anybody know where I can get some cache for cheap/trade? -- --- Dave Woyciesjes --- ICQ# 905818

PDP-8/I memory problem

by root＠parse.com

Hi folks, I'm in the process of restoring my 8/I, have run into a little problem with the core memory, and am out of ideas on what to do next. The symptom is that I can deposit into the core memory now (after replacing a few cards and a core plane), but I can only deposit 11 bits; the 12th bit remains 0. If I deposit 7777, I can examine and get 3777. This machine has 8k of core, and the problem is the same in both 4k banks. Here's what I've done so far to try and eliminate / narrow down the problem -- any further suggestions are most welcome! Swapped G228 A36/B36 Swapped G228 B36/B37 Swapped G021 A31/A32 Swapped G221 C37/C38 Swapped G221 D37/D38 Swapped two edge M220's Swapped G624 A38/B38 (The G221 swaps may have been related to an earlier problem, which I've since fixed) None of these swaps yielded any change in the problem... Since it affects both banks, I'm assuming it must be a problem in some common circuitry. Just so as I'm not totally embarrasing myself, the 4000 bit (the LEFT-most bit) is MB00, right, and not MB11? :-) This whole MSB = 0 and LSB = 11 is very confusing :-) Thanks!

S_L_O_W downloads with Adobe Acrobat was Re: Information about a HP 13197 1K WCS for the HP 1000?

by rigdonj＠cfl.rr.com

Last week I was having a LOT of trouble downloading PDF files from Al's website. Adobe Acrobat was taking about ten minutes just to open the first page and I couldn't get any pages beyond the first one. Erik suggested that I right click on the file and save it without opening Adobe Acrobat. I tried that and it worked MUCH better. However Al said that I should be able to open the PDF file with Acrobat and read it and then save it without any problems. That agrees with what I knew about PDFs. Anyway I've been wondering what was going on so today I typed "Why is Adobe Acrobat slow" into Google and I got some interesting results. I found LOTs of reviews of Acrobat version 6 that also complained about it being SO SLOW. Some of the reviewers suggesting sticking with Version 4. Following their advice I uninstalled my current version of Acrobat (ver 5.something) and then went to oldversions.com and downloaded version 4 and installed it. It works MUCH MUCH better! If you're having problems with Acrobat being slow. Try removing it and then installing version 4 and see if that helps. It works for me! Joe At 02:11 PM 11/4/03 -0800, you wrote: > >> You're not supposed to view them in your web browser. > >It should work fine that way, assuming the pdf plugin is sending the >right html commands to the web server. That's what I thought! But I tried saving the files directly and it worked MUCH better. I could save an 18 Mb file in a couple of minutes that way. Using Acrobat I couldn't even get one page in the same time. I tried to open and save a 9Mb file last week and it ran for over 2 1/2 hours and only got about 1/4 of the file before a power glitch crashed the computer. No idea why Acrobat slows things down so much. It doesn't seem to be a problem on small files but the time seems to go up exponentally with file size. I see people reading docs this >way all the time. > >To answer the original question, the WCS card is documented in the >1000 M/E/F Engineering Reference >http://www.bitsavers.org/pdf/hp/1000/1000_MEF_EngrRef/ I couldn't find a specific docs for it but I thought it might be in the Engineering Reference.

"Woz" IIgs, & Dynabyte computers...

by dwoyciesjes＠comcast.net

Anybody looking for these? I was at Computer Recycling & Refining in North Branford, CT today. Not a bad place. About 2000 square feet. And a bunch of stuff. Two interesting things I saw were a "Woz" signed IIgs (?) and a Dynabyte computer. According to the guy there, it was the first portable? Considering it's about the size of a couple mid-tower PCs, it's not really that portable... Either way, both are for sale. Give them a call, 203-488-0535. If you looking for some other PC or Mac computers or parts (pallets), maybe some HP switched hubs (at least 1 pallet), or even a couple large Cisco Catalyst 5500 units; they may be able to help you out. They welcome visitors, just call in advance... -- ---Dave Woyciesjes ---ICQ# 905818

Is there a physicist in the house?

Heisenberg says we can't know the speed of <thing> and it's location at the same time. What if I concentrate on location while timing <thing> ie <thing> is at "5" and 1 second later it's at "35" is it not going "30" per second? and while it was going 30 per second didn't I see it at 5 and 35?

Non crap plastic glue

"Glue" is very plastic dependent. Different solvents or adhesives for different plastics. Most plastic models are styrene, and the solvent in your typical model "cement" is MEK (Methyl Ethyl Ketone) which can be bought by the pint in the paint/solvent section of good hardware stores. Many model builders use liquid cement, which avoids many of the fillers and other stuff in the viscous tube cements.

Compaq Portable in PDX

by kd7bcy＠teleport.com

I've decided that I don't really like old PC's(altho I'll still keep my 5150), so I am getting rid of my Compaq Portable. It worked last I plugged it in about a year ago, I haven't tried it since - so no guarantee that it still works(but it should). It's been sitting in the basement and never gets used and I have too much stuff so it has to go. It has a half-height hard drive - something like 20 or 40MB, and a full-height 5.25" floppy drive. It's available free to the first person who can pick it up in Portland, Oregon. This is a pick-up only, I'm not going to ship something this big. Any takers? -JR KD7BCY

A good customer of mine is about to throw them out. Sorry it will need to be a local pickup. Yes I am still subscribed but have not been able to keep up with all the traffic.:( Thanks Dan

PDP-11/44 want list

The H7140 is one of the most complicated PSUs you'll ever come across, and it's also dangerous inside. There's rectified mains (400V DC at essentially unlimited current -- the smoothing caps are the size of coke cans!) on screw terminals on the top of some of the PCBs. This _will_ kill you, if you touch it. Not 'might', will. Basiclaly, there are 3 switch-mode PSUs in that box. The first is a small one, used to power the PSU control circuitry. The second provides the +5V and +/-15V logic supply rails. The last provides a +36V rail that can be battery-backed. That one is then regulated down to +/-12V and +/-5V for the memory boards. It also supplies the H-bridge driver that provides the 35V 70Hz supply for the fans. The schematic for this supply is a dozen or so pages. I wouldn't want to work on one without it in front of me, even though I've repaired them before... -tony

HP CRT Mold

by sloboyko＠yahoo.com

I unsubscribed from this list because of the volume, but I still read the monthly archives. I noticed than some people were wondering about the HP CRT mold problem. I really did solve it, by building a wooden box (to contain the IMPLODING crt), and mounting the CRT in it. Then, I went to the hobby store and got some nichrome wire used in cutting foam for model airplanes. I used an old AT power supply at 12 volts to power the wire, to just below red hot (I determined the length of nichrome wire to do this with expermentally, it was about 3.5 feet). I made wooden handles with screws to hold the wire as I sliced through (very slowly!!!) the old RTV, keeping the nichrome wire towards the front glass and not touching the CRT. after the front glass came off, acetone was used to remove the remaining old RTV, and all glass surface were cleaned spotless before reassembly with aquarium RTV around the edges. Of course, this was all VERY VERY hazardous and no SANE person should EVER even CONSIDER doing this (liability issues...). I completely restored my 2644A including getting both tape drives working, good matching paint, and I even buffed the yellowing keys back to original condition (very tedious work). But it is an amazing, cost is not object machine. The switching power supply is crystal controlled!!! My tube didn't have very serious phosphor burns so I felt that it was worth this effort. If anyone wants the CRT box they can have it for the cost of shipping. Hope I won't have to use it again! You actually can buy NEW crt's like this one - for $250!!! I also put new CRT's in my ADM-3a's (much cheaper, around $45 shipped, as I recall). Some details on the HP and ADM-3a CRT replacements are at: http://juliepalooza.8m.com/sl I've been working on 6120's, tiny paper tape readers powered by laptop power supplies, and a Scelbi clone capable of running SCELBAL (which I have resurrected). ===== -Steve Loboyko Incredible wisdom actually found in a commerical fortune cookie: "When small men cast long shadows, then it is very late in the day."
