I'd have to buy oil, buy a filter, get the truck up, drain it, then figure out what to do with the old oil, as here you have to pay to dispose of it. Frankly, by the time it's said and done, most times it's cheaper to have someone do it, as someone ALWAYS has a special in my area for $14.99-19.99. Of course, sometimes I'll do it just because i feel like doing it... However, things like brake work, etc, I'll do myself. It's highway robbery what they charge. Last time, they wanted $149.99 parts+labor to change the stinking brake PADS on my pickup!

I mean, yeah, it'll take a while to get people looking at the code, figuring it out, etc... but at least you have SOME kind of chance! One prime example is Royal Caribbean. They run a property management system named Encore, which originally was named "The Captain," from a company named Encore, which ran on Tandems (I think on Linux now, or will be - most dev systems are under SCO or Linux, and the programming environment is DB/C), and they had a source code escrow agreement. When Encore went under (I think RCI was their only major deal), they basically bought the assets, and got the source out of escrow, and have maintained it in-house ever since. Tony

about shipping

by dgriffi＠cs.csubak.edu

Some people have asked me to catalog and ship stuff from my storage unit. The stuff for which I can do that I list on Ebay (http://myworld.ebay.com/frotz661). A batch of ten items goes up this Tuesday and more will go up in similar volumes in the coming days. What I'm asking people to do is come and cart off mostly documentation that I haven't the time or willpower to catalog and scan. If you see something special sitting alone, make an offer. There are also some large "good lord, what is that?" things that someone might be more interested in than the scrapper would. I'd love it if I can get someone from southern California who, for whatever reason, needs to drive up to the SF area to stop off at my place to get a load for the Computer History Museum. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Stuff to get rid of in Bakersfield California

by dgriffi＠cs.csubak.edu

I have too much crap in my storage units and I need to get rid of one. I thought I'd be able to sell off this stuff on ebay, but I don't think I have the drive to deal with the volume I've amassed. The highlights here are a Macintosh SE, a Northstar Horizon (missing the lid), several 8-inch floppy drives, assorted S100 cards, and lots of documentation.

Osborne items available

by tonym＠compusource.net

For Osborne 1: 2 floppies, setup as A: and B: from factory CRT Mainboard (SD, but I think I have one DD upgrade board) I THINK I also have a front panel or 2 No case or psu available - PSU was bad, and case was in HORRID condition For Osborne Executive: CRT, FDD's, frame, and questionable mainboard for Exec, although 128kb ram card IS good. CRT and Mainboard are questionable, so those 2 can go free+shipping. Might also have the front panel for this... Make an offer that at least covers gas to the post office :) Items are in S. Fla Tony

ENIAC vs. ENIAC-on-a-Chip IC implementation

by wbblair3＠yahoo.com

>From the excellent book, "The First Computers - History and Architectures," an interesting comparison: "The ENIAC contained 17,468 vacuum tubes, 70,000 resistors, 10,000 capacitors, 7,200 crystal diodes, and 6,000 switches, it had a footprint of about 33 m x 1 m, occupied a room of 170 square meters, dissipated about 140-174 kW and weighed 30 tons. In contrast, he chip realization contains 174,569 transistors, measures 7.4 mm x 5.3 mm (the PGA package measures 3.6 cm by 3.6 cm), dissipates a few Watts (depending on how many units run in parallel and the clock speed), and weighs a few grams. Also, in terms of power requirement the comparison is striking. In addition to the AC power for the heaters of the tubes, the card reader and the card punch, the ENIAC required 78 different DC voltage levels to power 10 different types of vacuum tubes. The power equipment was housed in 7 panels which were separate from the ENIAC?s 40 panels. Special ventilating equipment consisted of an elaborate system of fans and blowers to keep the temperature inside the panels below C. In contrast, the chip needs only one power supply of 5 V (or lower). The clock frequency used in the ENIAC was 100 kHz, while the one on the chip can easily run at 50 MHz or higher." http://www.ese.upenn.edu/~jan/eniacproj.html

Uses for OpenVMS

by poghlan+cctech＠vms.eurokom.ie

>I've had a VAXstation 4000/60 in my cabinet for well over a year now (had to >renew the license a few days ago). It is running OpenVMS 7.3. > >I can not think of any use for it, other than learning about OpenVMS, but that >is made difficult when I don't know what to do with it... > >So what can be done with an OpenVMS setup these days? > All sorts of stuff. Here are a few varied examples: Most recently, I hacked together some bits of other peoples C code to take a .au sound file and generate a graph of its frequency spectrum in an XWindow. I put this together on an Alpha where my sound card is but I just tried it on a Vaxstation 3100 and it it worked fine there too, a bit slower though. I have the Hercules IBM mainframe emulator running under VMS on my Alphaserver 1000A. That should annoy the DECheads and IBMmers in equal measure :-) Hercules is a medium sized application targeting linux and windows. I can scan documements using a SCSI attached scanner on my VAX 4000/100A and a port of the SANE scanner software and view and archive pictures from a digital camera using an "interesting" method of attaching a compact flash card to my Alpha. Recent versions of VMS including 7.3 provide a unix like runtime environment which makes it possible to port many of the better written open source unix applications and tools. The windowing system is a port of X-Windows so even if you don't have a display attached to your VAX, you can run X-Windows code on your VAX and display it on a remote X server which could be on a PC or Mac for instance. Lots of X applications and games have been ported to VMS and there are ports and native versions of internet applications such as email and news clients and servers, web servers and even web browsers. Unfortunately, a lot of the more bloaded modern code would have problems building or running on a VAX. VAX hardware is out of production for some years now, having been replaced by Alpha and then Itanium processors and VAX systems tend to be limited in processing power, memory etc compared to their successors and to the expectations of more recent code. Also, some features which were later added to Alpha/VMS (such as kernel threads for example) were never backported to VAX/VMS. I like programming in the native VMS environment. I generally use C, Fortran and VAX assembly but lots of other languages are available under the hobbyist license. VMS System service routines and library functions are available equally >from all languages and are in general very well designed and offer great flexibility. The downside is the learning curve can be a bit steep for someone who is not familiar with the VMS way of doing things, which can be quite different >from other operating systems. There is lots of freeware for VMS at http://mvb.saic.com/ which may stimulate further ideas. Also, check out the comp.os.vms newsgroup where lots of VMS people hang out. Regards, Peter.

After that, all the Linux/Open-Source bigots came out decrying it. OpenOffice was menetioned as being the be-all end-all and being free, and I promptly downloaded it, installed it, and it wouldn't even open 1/3 of the work my wife did last semester. Now, does that mean it sucks? No. Did I say it sucked? No. But the Zealots took it as such, and kept going from there. I never said you couldn't use Linux+OO in school - I am sure MILLIONS already do. I just made the point that it was NOT the right solution for my wife. She is not exactly, um, computer saavy, and has no desire to be, so for my situation, I saw it best to give here Windows+Office, because working 10-12 hours at the office, and then 4 more VPN'd from home, I REALLY didn't want to add to my load... But the bigots INSISTED... I am in TOTAL agreement with what you say - we run many environments at work, and there are MANY instances where Linux is the ideal solution. We currently have about, oh, let's say 12-18 Linux servers at work, (2) of which are hosting semi-large Oracle databases, on the order of about 40GB, and running on HP Proliant DL380 G3's or G4's (depending on age) and either (6) 72GB or 146GB drives in RAID5, again depending on age. They run fine, work fine, kick the SNOT out of equivalent Windows boxes hosting Oracle, and as you pointed out,I have NEVER had a virus/malware/trojan issue to speak of. And we all know that is NOT the case with Windows boxen! As to TCO, well I don't know what you're getting at, as I just pay yearly fees for the M$ True-Up, and the eTrust AV. Comes up to about $785/year for both. Now, workstations are a bit more, and btw, all ours are NOT the same, depending on age, and the property they are at. I still have Compaq Deskpro EN (P3/800-1000) in the enterprise, HP Workstations, multiple versions of Dell SX and GX-series machines, And Dell/IBM Laptops (mostly Dell Latitudes now, D600/D610/D620/D630, as most TPads have been retired). And most times, I don't get a parts-swapping droid when we call HP/IBM/DELL - we usually get overnighted the bad part, so it's back up and running the next day, assuming next day service on that machine, and assuming not the weekend. The only exceptions are the servers, which come with a 3YR warranty, and we pick up the next day, 24x7 support on those. As I said...my first introduction to free *nix was 386BSD in about '94 or so, followed by Linux, although it was still 2 floppies, and then to FreeBSD, which was the next progression of 386BSD - played a little with Minix, but it was a bit closed-in for me - Linux was gathering steam, and developers were getting strongly behind it, which is when I switched over from *BSD to Linux. Things were happening REALLY fast in the Linux world, and were slowing down in *BSD. And then they started the whole *BSD split-offs I figured it was time to switch over for real. Heck, I think I still have quite a few of the older media around, back when Linux was the "In thing" and was being sold retail in Best Buy / Circuit City / etc.. I CLEARLY remember, before affordable WiFi days, the copy of Corel Linux I bought retail, was about the ONLY operating system, that out-of-the-box, would properly run with those RayCom 2MBit wireless cards. Not Windows, and not other Linux distros - I'm talking OOB, here. And I remember loading that on an HP OmniBook of some sort, Pentium 200 or so, as I recall... ps - forgive the formatting, as this is through my Webmail because my work XP laptop is, surprise, running malware / trojan cleaning apps.

Were there different personality modules? This was in a Kaypro 4, which had all the above mentioned items. It currently is NOT working (strange squiggly horizontal line in the center), and the personality module looks rather simple. This machine also had (2) HH floppies, and a third FH in the bottom. Had a toggle switch with a proper label putinto the front panel for the TurboBoard, and an RCA jack on the back for the ProGraphics module. Very interesting - I'd never seen a ProGraphics board before. I'm going to start taking it apart to see what the issue is, but there are so many solder jumpers, and mini-grabber clips, I will have to take careful note of how everything currently is, before I start troubleshooting. Gotta make sure the mainboard has no issues, first and foremost. Tony

I maintained Nike Antiaircraft Missile systems in the mid 1950s. We used a phantastron circuit http://ed-thelen.org/diagrams.html to generate a pulse to compare with the timing of the received radar pulse from the target. http://ed-thelen.org/ifc_track.html The range tracking circuits compared the timing of the two pulses for operator optional automatic range tracking. This was part of the target range tracking system, which had to be as identical as possible with the missile tracking system to provide accurate voltage information to the analog computer for missile steering - http://ed-thelen.org/computer.html To help calibrate both range systems, we used pulses from a 100 KHz crystal controlled oscillator.

Tony, You want to check with "Sharkonwheels" who posts on _www.vintage-computer.com_ (http://www.vintage-computer.com) . He is very knowledgeable on Kaypros "after" 1983. He uses and has info on Advent products. I am more involved with the 1982 / 1983 versions and post under GADFRAN. My website _www.kayprosts.org_ (http://www.kayprosts.org) may give you some other productive contacts to explore. He may also know of HandyMan. You may want to check just what version of K4 you have. Main large chips on main board will help - e.g. U43 and U47, etc. He will be asking you about them and other aspects. He is very familiar with the K10's. Hope this helps some.

VCF East 5.0 just two weeks away!

by evan＠snarc.net

Now that the list is running again, I want to invite everyone to VCF East 5.0, Sept. 13-14, at the InfoAge Science Center, in Wall, New Jersey. As usual we'll have awesome exhibitors. This year we also have two special events: Vince Briel's replica creation workshop, where you can build a replica of the Apple 1 or the KIM under Vince's guidance, and we'll have a ceremony and tours for the "beta" opening of our computer museum. (We've been in "alpha" for the past two years.) Sign up for Vince's workshop at http://www.vintage.org/2008/east/workshop.php?action=select <http://www.vintage.org/2008/east/workshop.php?action=select&id=104> &id=104. We'll also have some cool guest speakers. Most notably, on Sunday, we have Bill Mauchly. Bill is the son of ENIAC co-inventor John Mauchly. We also have a lesser-known engineer named Watts Humphrey, who wrote the proposal for the military's "MOBIDIC" computer in the 1950s; it was an early example of client-server architecture. And we've got Claude Kagan, who spent 30 years at Western Electric and Bell Labs and who worked to get our museum a first-generation PDP-8. Tickets for one day are $10, both days combined are $15, and anyone younger than 18 is free. Parking's free too. - Evan

My interest lies mostly in the CP/M variants, although I have a few K16's, and I *WOULD* like to eventually find a K2000 - those were pretty unique machines! Tony

MY REPLY - Re: HandyMan for Kaypro

Frank, I very much appreciate the response - however, *I* am Sharkonwheels on VC! :) I've never run into a HandyMan, though... 'ppreciate the confidence, though! Tony -----Original Message----- From: FJGJR1 at aol.com Sent 8/31/2008 2:23:27 PM To: cctalk at classiccmp.org Subject: MY REPLY - Re: HandyMan for Kaypro Tony, You want to check with "Sharkonwheels" who posts on _www.vintage-computer.com_ (http://www.vintage-computer.com) . He is very knowledgeable on Kaypros "after" 1983. He uses and has info on Advent products. I am more involved with the 1982 / 1983 versions and post under GADFRAN. My website _www.kayprosts.org_ (http://www.kayprosts.org) may give you some other productive contacts to explore. He may also know of HandyMan. You may want to check just what version of K4 you have. Main large chips on main board will help - e.g. U43 and U47, etc. He will be asking you about them and other aspects. He is very familiar with the K10's. Hope this helps some.

Anyone remember how to use a HandyMan for the kaypro? This was an add-in board, piggy-backed between the Z80 and socket, and had a TSR-like pop-up Borland SideKick wanna-be. Trying to find some info, as a K10 I acquired came with a handyMan, and Advent 1MB RAMDisk, and K4 came with an Advent Clock, RamDisk, ProGraphics board, Personality module, and 5mHz turboboard.

Check _www.vintage-computer.com_ (http://www.vintage-computer.com) and do a post. Also check their links, especially I think it is _www.bitsavers.org_ (http://www.bitsavers.org) [com?] in Britain. They have free downloadable manuals for some Kaypros and other computers, which should give you the specs. "Sharkonwheels" posts on this site and he is big into a lot of Kaypros, but not the 2000 I think. You can also check my website for other contacts - _www.kayprosts.org_ (http://www.kayprosts.org) . But I am more into the first Kaypros before 1984. Kaypro 2000 certainly was something for its time! Good luck! Frank In a message dated 8/29/2008 12:45:34 P.M.

Schematics of Atanasoff-Berry Computer logic circuits?

A scan and my > re-organised versions are accessible at: > > http://www.cs.ubc.ca/~hilpert/e/ABC/asm.html Thanks, that's a really great start. Prior to seeing your reply to my question, I requested an inter-library loan of the book "The Origins of Digital Computers - Selected Papers" which contains the paper which is excerpted on your excellent ABC site. Even though that book now looks like it won't provide the details I'd expected, since I won't be using the same voltages as the original circuits were likely using, the exact component values will be different anyway. I'm not very familiar with vacuum tube circuit design, but I have a PDF copy of the 1952 USAF technical order TO16-1-255 "Basic Theory and Application of Electron Tubes" which looks like it might be sufficient. I've built two different 12AU7 dual triode vacuum tube stereo headphone amps from plans which use much lower and, therefore, safer and easier-to-produce voltages (24 - 60V) than were used historically in such circuits. The required plate voltages for these low-power circuits are produced using simple voltage multipliers attached to commonly available and inexpensive low-voltage transformer secondaries. Since, in the case of digital logic circuits linearity of operation is not a requirement as it is with audio circuits, even lower voltages might be usable although 24 volts seems to be plenty low enough. > I was doing some calculations and experiments with vacuum > tubes a couple of years ago to recreate an ASM, to figure out > what might work for the logic-resistor values (not completed). > It would be nice to know what the original values were. > > If you are referring to the schematics for the entire > machine, I had the same interest when I was working on writing a > simulator (also on the web pages) to confirm some aspects of the > functioning of the machine.

That's strange that they'd be so restrictive about the distribution of schematics for a machine that has no current value beyond that of a historical curiosity. I know that there was a legal battle between Mauchly with his ENIAC and Atanasoff with his ABC, but that was decided against Mauchly and claimed that his ENIAC plagiarized concepts used by Atanasoff's ABC which then invalidated Mauchly's earlier patent claim to the first electronic computer. Since Atanasoff won the case 35 years ago, why would they not willingly release all schematics now?

Right you are. I've already received a reply to the effect that he will check with applicable points of contact. I'll let you know the results. Thanks, Bill

You gotta dig REAL deep, apparently, to get past the bigots...I know a few people on the list, and when they suggested I join a few months back, I didn't realize what I'd find. Scary - some need to SERIOUSLY unplug, and learn to deal with humans again, because people skills are nowhere to be found! No matter - enjoy, and keep an eye out at that link, as they are supposed to have Vista Ultimate for $65 in a week or two. Oh, and to please the offended, yes linux is free, yes it's wonderful, yes it will do EVERYTHING your heart desires, oh, and yes, it's free.
