I am in on a group purchase if it is feasible. I would be happy to just get few interesting S100 cards. An IMSAI as a "spare" for my Altair would be nice. -----Original Message----- From: Rich Beaudry [SMTP:r_beaudry@hotmail.com] Sent: Friday, April 20, 2001 2:55 PM To: classiccmp(a)classiccmp.org Subject: Z/H 100 AND S 100 PARTS Just spotted this message on comp.sys.zenith. Anybody else interested in a group purchase? Unfortunately, "no lists and no viewing" makes it difficult, but if we could convince him of the number of people interested, maybe he would change his mind?? --------- I just purchased 5 Condo Aircraft Hangers at our local Airport. One hanger has a collection of hundreds of H/Z 100 computers and related parts Also there are many IMSAI, ALTAIR and other Vintage computers plus cards and related parts. The amount is staggering. I need to get this stuff sold hopefully before the end of the year so I can get it rented for Aircraft purposes. I do not intend to use E-Bay at this time. I am also going to add myown extensive supply of H/Z 100 stuff and S100 items to this pile. No lists will be provided and no viewing. Send me an E-Mail or phone me.

International Microsystems 1010 Programmer

by r_beaudry＠hotmail.com

Hello all, Recently I purchased an IM 1010 Universal PROM Programmer, serial number 448. It has one personality module, HAGEN1 1, and one adapter, 512x8. This is an old programmer (somewhere on the order of 20+ years old), but it still appears to function. The manual I received with it, however, was basically just a device support list, and did not contain any operating information. I opened the device, and lo and behold, an Intel i4040 was inside, along with some other Intel 42XX chips of that family (MCS-40, I believe). There were also several TI 2516 EPROMs, some RAM, and discrete stuff. I did not disassemble the display or keyboard. A serial port is on the back, and the unit came w/ a serial cable, but I have not hooked it up to my computer yet ..... I powered it up, and it appears to function. The display lights up, and by playing with keys I can get address counters on the display to increment, and I think I can store values in RAM.... - Does anyone have an operations manual for this programmer? I would gladly pay copying and postage... - Does anyone have personality modules and adapters that they'd be willing to part with? :-) Or perhaps schematics for some of them, so I could build my own? This beast supposedly could program 1702s and 2708s with the right adapters, so if I could make those, I'd be VERY happy.... Thanks! Rich B.

VAX 6000 3-phase conversion (was: Re: Three Phase)

by gunther＠aurora.regenstrief.org

Sridhar, here is the URL to this material: http://www.decvax.org/vax6000/power.txt I have tried to mail the wizard who writes the in depth stuff, but his email address is no longer valid. So, what you see is what you get. I have thought about this again last night and came to a conclusion that I should just try it out. DISCLAIMER: I AM NOT COMPLETELY CONFIDENT OF THIS AND I HAVEN'T TRIED IT OUT YET. SO, READ ALL OF THE BELOW CRITICALLY, DON'T JUST TRUST ME BUT THINK FOR YOURSELF. PLEASE LET ME KNOW ANY CONCERNS OR DOUBTS YOU MIGHT HAVE ABOUT THE CORRECTNESS OF WHAT I SAY BELOW. Let's look at the plan again: ____________________ +300V | | | -__ -__ -__ thyristors ^ ^ ^ | | | L1 ------* | | L2 -----------* | L3 ----------------* | | | - - - diodes ^ ^ ^ | | | --------------------- Return ---- FOR 220 V SINGLE PHASE ----------------------------------------- With a 220 V single phase power supply (P and N coming out of your receptacle,) as in Europe, Australia, India (?), etc. all you would need to do is, e.g., put P on L1 and N on L2. That gives 220 V ~ input and if this sqrt(2) rule is correct (which I'm still a little confused about) you get 220V * 1.414 = 311.8 DC, i.e., just right. As Leon, the lost wizard of ZA, assures us, the thyristors and diodes are dimensioned so as to withstand all the power load coming through L1 and L2 only. If we want to be double sure, it should not hurt to, say, splice the P (or N) and connect to both L1 and L3. Of course it doesn't matter where exactly you put P and N and which of those you distribute over the two input lines. My guts suggest to splice P on L1 and L3 and N on L2, but that's for no rational reason. Also, I would not want to miss connecting the protective ground to the metal cabinet (wherever the protective ground should connect at the AC input, which I'm not sure about.) ---- FOR US 2 x 110 V TWO PHASE ------------------------------------- For the US I am thinking that may be the 2 phase 220 V dryer hookup is the best way to go. Not only is this line at a convenient location where you can store a big cabinet like this one, it is also well dimensioned to sustain a VAX or (and may be AND) your dryer. Otherwise, just dry your clothes on a line. But do not mistake the VAX's blower with your front-loading washer :-). Seriously, the two phases here, as I understand it, are: ------- P1 ------- N ------- P2 with U peek = 110 V and the phases of P1 and P2 being displaced by 180 degree. So, if you measure U between P1 and P2 you get 2 x 110 V = 220 V. So, I would then connect it like this: ____________________ +300V | | | -__ -__ -__ thyristors ^ ^ ^ | | | P1 -L1 -----* | | (N)-L2 ----------* | P2 -L3 ---------------* | | | - - - diodes ^ ^ ^ | | | --------------------- Return I am not sure whether to use N on L2 or leave N open (again, I notice how much I forgot about my high school physics.) This actally bugs me, because I don't know quite where to connect to the ground potential and how to deal with the protective ground here. I *think* that when I have the N connection open, I will have a higher DC output than when I close N on L2. But I don't know. Can someone throw in his opinion on the matter? I should at least be able to try this out without being afraid of breaking anything, since P1 P2 alone work just like 220 V European power. At least, I am using my old German electric devices on this kind of power hookup from my 60 A extra two-pase line. Any comments, warnings, advice? thanks, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistent Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

OT: 25 SIGNS THAT YOU'VE Had TOO MUCH OF THE 90's AND 2000

by mmcfadden＠cmh.edu

Our power was off for 4 hours in a recent thunderstorm and the first thing I tried to do when it went off was try to login to look at the National Weather service Doppler image of the storm. My UPS keeps the cable modem and router up but the PC was dead. I was holding a flashlight in my mouth when I tried. It's actually pretty neat to see the image and recognize that the storm cell is probably over my house. Mike mmcfadden(a)cmh.edu

Low ceilings and other impediments (includes floods)

by mmcfadden＠cmh.edu

Floods Our computer room was on the 10th floor of an office building and the drain for the water cooled air handler dumped into a sink in the hall next to the elevator. The cleaning crew left a mop in the sink and it clogged up. We flooded the entire area below our raised computer floor. Amazingly the PDP 11/70 and RP04 kept on running, we noticed the problem because of the humidity in the room when we came in. Nothing like mold covered cables in raceways. We tried wicking the water out and blowing hot air under the floor, the mold really liked the hot air. Being on the 10th floor surrounded by low buildings we used to estimate how many mag tapes we could braid together to escape from a fire, we knew the ladder trucks couldn't reach us. We also estimated the disk safe with our backup disks would probably end up on some lower floor. Mike mmcfadden(a)cmh.edu

strange find!

by rigdonj＠intellistar.net

I helped a friend of mine pick up a load of surplus stuff today and one of the items that I got was a bag of keyboard overlays that came from Tektronix. The Tektronix tag on the bag is dated 1973 says that they're for a PDP-11! The overlays appear to be for a numeric pad or something similar. They have cutouts for four rows with four keys in each row. The overlays are all marked as "User Definable" so the key positions are unmarked except for Cont, Reset and CPU Busy in the last three positions in the bottom row. There are four orange color overlays, five yellow overlays and five blue overlays in the package. Does anyone know what these are four???? Joe

I guess if the early 1970's counts as fairly late, anyway... I can't speak for the 60's, but in the early 70's Samsonite (yes, the suitcase people) had a plant in Englewood making an 18 bit minicomputer. They called the company Electronic Processors, Inc.

Preventing users from loggin into a unix box

On Apr 19, 17:50, Ram Meenakshisundaram wrote: > Gene Buckle wrote: > > > do a touch /etc/nologin > This wont work as nologin is just a message file (similar to motd) whenever the system is about to shutdown. That's not what it's "supposed" to do -- it's supposed to be checked by 'login' and if it exists, cause login to refuse to accept the remote login, and print the contents (if any). Some versions of Solaris don't honour that, though :-( They just use it to contain a message given to anyone attemting to log in while a shutdwon is in progress (it's not the message printed to active sessions when a shutdown starts, though). If your system uses NIS, then you could just change the contents of the passwd line in /etc/nsswitch.conf from "passwd: files nis" to "passwd: files" and add your own entry to /etc/passwd and /etc/shadow. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

Latest finds - Tandy 1000 and "Code Name: Sector"

by ethan_dicks＠yahoo.com

The Tandy 1000 was a freebie (from a friend from a cow-orker who wanted $20 for the dot-matrix printer, but the computer was free). The other item is a Milton-Bradley electronic sub hunt game from the late 1970s. Electronically, it resembles Mattel football and the like - a window of LED displays, a few discretes (to indicate cardinal points on a compass) and a bunch of buttons. The manual is present with a tutorial. Apparently, you reset the thing, then plot ship courses with crayons on a grid map, punching buttons all the way. I can't imagine trying to _actually_ play the game, but playing *with* the game was fun for at least as long as the tutorial lasted. Oh... the game was $0.67 at a thrift store because it was 75% off day for green tags. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

TK70 / CompacTape II anywhere?

by gunther＠aurora.regenstrief.org

Hi, where do you think one could buy new or used CompacTape II (TK70) tape cardridges? It looks as if they're nowhere to find on the net. Well, I suppose one could use the new 24 GB DLT cardriges, but they are terribly expensive just for the poor VAX 6000 hobbyist. I and my fellow VAXhaxer appreciate any help, thanks -Gunther

small TCP/IP package installation question (in RT11)

by GOOI＠oce.nl

OK. Thanks for all the advise. I am using PUTR too, of course. Unfortunately, the firewall of our company does not allow FTP.... Lucky me that I bought the RT-11 Freeware CD-ROM from Tim. On it is the small FTP and Telnet package as well, in a .DSK and as a directory with the seperate files in it. Saves some download time. > BTW, one word of advice, follow the instructions to very > carefully, you'll save yourself a lot of headaches! So, I guess I will encounter the same pitfalls.

OK, in this case it may be more a question of convenience, but if Ram has the access (ie, access to the root account) to do all these things, he would be better to either do as Gene suggested and "touch /etc/nologin" (or put some text in it: the contents are printed by login before it closes the connection), or to do it properly and run tcpwrappers, with suitably set up /etc/hosts.allow and /etc/hosts.deny files -- then he can control who can connect, from where, and using which protocols (telnet, rlogin, rsh/rcp, ftp, ssh, etc). If you *are* thinking of security, remember that inetd only controls some network services -- some, like SMTP, HTTP, SNMP and others, normally run as daemons in their own right. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

Anatomy of a VAX 6000-420

by gunther＠aurora.regenstrief.org

Hi, as promised here is my photo series on systematically disassembling a VAX 6000-420. I do not envy you poor folks who thought simply taking out the card cages and the cab kit would allow you to somehow put this back together to a working machine. Has anyone ever actually done this? Anyway, here is my VAXian anatomy page: http://aurora.regenstrief.org/VAX/anatomy BTW: I (and a few friends) am still looking for advice on how exactly to convert the power unit so as to hook a VAX 6420 on 110 V houshold power. Either 110 V single phase or 240 V 2-phase would do. I have done electronics in my youth, but I have no clue how to go about it and don't want to go trial and error :-) Any help is appreciated. regards -Gunther
