Naming schemes (was upcoming classiccmp wierdness)

by blstuart＠bellsouth.net

> I'd be interested to find out what network names/nicknames some other > classiccmpers have given their machines. I've been using intellgent computers from sci fi for a while. The laptop I'm using now is called nomad (from Star Trek) and my gateway is called orac (from Blake's 7). I've got some Suns that I hope to have back on-line soon with names like colossus, guardian, hal, m5 and zen. Of course, my daughter wanted me to name her machine fluffy (from Harry Potter) and my wife's is taliesin (from Arthurian legend). BLS

acrhival/displays

by joel.bradley＠comcast.net

Hey guys, I am 'new' to the list under this address. I have posted several times about CDC items I have available, and thank you to those who have expressed interest. I do not wish this to come off as a blatant advertisement, but it probabaly will. If any of you out there are looking to 'decorate' your offices or hobby spaces, keep on reading. One of my other hobbies is sports memorabilia and I have something that I developed for my own use in displaying my collection. Being that there has been talk about manuals, old computer magazines, and the like, I thought some of you might be interested in what I am 'selling' to display your ietms. I actually have them listed on eBay, but I can give a better price to those on the list that contact me directly. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2760307223 I have been a collector of magzines for almost 10 years and have been looking since I started for an attractive way to display my collection. In conjunction with a local custom acrylic fabricator, I came up with the following... The holders are made from a combination of 1/8" and 3/16" crystal clear anti-static (anti-dust!) acrylic and can be made to either 'hang' on the wall or 'stand' on a shelf/desktop. They are made from 2 pieces. Imagine one of the pieces is like a shoebox lid. The second piece is the 'back' of the holders slides in and out along a routed edge that is on 3 of the sides of the 'front', You access the box which holds the magazine by sliding the back out. The genius of this design is that it completely seals it inside for protection. They come in various sizes, as well as two 'flavors', hanging or standing. If you go to the listing on eBay, you will see a picture of the 'standing' kinds. I have pictures of my magazine collection using the 'hanging' type available as well. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2760307223 Feel free to contact me directly with questions. Thanks! Joel Bradley joel.bradley(a)comcast.net

Available PDP-11 Cabinet, St. Louis

by ohh＠drizzle.com

Like I said a couple of days ago, I'm meeting the nicest people lately. :) Though I still haven't found the PDP-12 I can afford to buy just yet, I have found an empty PDP-11 rack looking for a good home: > This is not exactly what you were looking for but I have a PDP-11 > cabinet i would like to give away, it is the rack only with a pdp-11 > bottom panel, ~6' tall, 2 fans in top, some slides installed, on > casters with leveler feet. Free to a good home. I am in the ST. Louis > area. Anyone interested, particularly in or near St. Louis, can e-mail the owner at "rhugh a-in-a-circle att black-spot net" (with the two appropriate, and I hope obvious, substitutions). -O.-

air filters

by jwest＠classiccmp.org

I was looking for air filters for DEC RK05, HP7900A, and HP7906. I found one website that I sent an email to the company asking for prices and here's what I got: DEC RK05 - 67.00 HP 7900A- 74.00 HP 7906 - 73.50 This just seems ludicrous to me. Anyone know of better priced sources? Jay West --- [This E-mail scanned for viruses by Declude Virus]

Data I/O Series 22 EPROM Programmer help

by ian_primus＠yahoo.com

A friend and I are working on building a simple Z80 computer from scratch. We've got a pretty good start on it so far, but have run into a little snag - an EPROM programmer. I have an ancient Data I/O Series 22 programmer that I have been attempting to get working. I have the manual, and I managed to get it to power up. The power supply caps were limping, but they seem to have reformed while I was playing with it. I am now able to turn it on and have it come on properly every time. I can read devices into RAM fine, and I have (I think) successfully erased an EPROM with the built in UV eraser. (When I read the erased chip, the checksum is 0000). This programmer has an RS232 port on it, and I have attempted to connect it to a couple of different things. First, I tried connecting it to the Linux box in the workshop, and tried copying the data from ram to the serial port while I had a "cat /dev/ttyS1 > file" running. This produced no effect, other than a zero byte file. I connected a VT220 terminal, and have been able to control the programmer (to an extent) from the terminal. I can type the commands for copy, etc. But, the manual states that I should get some feedback on the terminal screen, as well as on the programmer's readout. So far, I have yet to see a single character come out of that programmer through the serial port. I know I have the baud rate, parity and stop bits set correctly. I even tried connecting my even more ancient Tektronix "doghouse" (German Shepherd sized) 'scope to the RS232 TX pin, and I haven't gotten a clear reading. Of course, my lack of a good reading is probably related to my lack of good probes, the ones I have are quick kludges with some old shielded coax cable, and are probably the electronic equivalent of pounding nails with a bowling ball (i.e. it works, kinda). Has anyone had any experience dealing with an EPROM programmer like this? What format is the data transferred in, and how can I communicate with the programmer from the computer. The manual is pretty cryptic about it, and mentions that the programmer is capable of sending and receiving data in no less than 20 formats, none of which seem like anything I have heard of before. What is the 'standard' method of transferring data two and from a serial EPROM programmer? Should I be able to see data on a terminal if I dump the data to the serial port, or is it in some non-ASCII format that the terminal (and Linux) can't render? I am lost here. Any suggestions would be appreciated. Thanks! Ian Primus ian_primus(a)yahoo.com

Naming schemes

by classiccmp＠crash.com

Oh what the heck, why not do my bit to congest the network... Can't tell who wrote: > > I'd be interested to find out what network names/nicknames some other > classiccmpers have given their machines. I picked crash.com in the Great Internet Domain Name Land Grab back in early 1994. Hard to believe what wasn't taken back then. As to why, well, what do computers do at the least convenient times? What logically followed (to me) was a series of names based on Unix signals. abort.crash.com Desktop buserr.crash.com Desktop fpe.crash.com Web server hup.crash.com Current firewall int.crash.com temporary, new machines io.crash.com File server segv.crash.com Old firewall term.crash.com Livingston Portmaster They've all been different machines at different times, as these are role-based names as much as anything else. And of course they have CNAMEs/aliases of the proper format: SIGHUP, SIGINT, etc. Other naming schemes in use are predictable. The Sun's are Egyptian gods (Ra Sparc 10/52, Thoth Sparc 20/92 (yes, 90MHz), Horus and Osiris are Ultra 30's, the Sun-4/260, 3/50 & 3/60 haven't been revived yet). The DEC MIPS and Alphas are Indian gods (Kali 5000/260, Hanuman a 3000/300lx, Siva a 600MHz PC164LX rack, new AS1200 and AS4000 haven't been named yet). The VAXen don't conform to this, I can't recall the name given to the uVAX 3400, the VS3100m38 only went far enough to confirm that it worked, and the 4000/500 is OMEGA. If I get the 11/730 running, I'll worry about a name then. The big problem there is what to do for mass storage, as I don't have a Unibus SCSI card and don't want to use a second backplane. OTOH, it might be faster to boot diskless and run over the net than hook up an R80... . The DG Aviions aren't really part of the network, and their names are stopgaps. An AV410 is "lilav", and the AV530's are Edson and Webo. I can't recall what name was given to the AV5500 just now. The cluster project was named arg.crash.com. The individual nodes (Soyo dual Slot 1 mobo's with Celerons on slockets - gives you an idea of timeframe!) were arg0, arg1, arg2, etc. I was tempted to rename the whole cluster argv, but... Laptops have been Slim (DEC HiNote Ultra), Slate (ThinkPad 600X), and now Folly (a ThinkPad T23 1400x1050 that I shouldn't have put the money into). Network attached HP LaserJet 4+ is Hardcopy.

Netbooting VAX-11/730 (was Re: Naming schemes)

Jochen Kunz suggested: > The NetBSD/VAX boot loader? > It uses DHCP and NFS to load an ELF image. This might work. This 11/730 was packaged in a low-boy (~42" tall) rack with RL02 on top, an R80 on the bottom. I received the host because it was crashing on bad sectors in the R80, and the person using it was given a free 11/750 & rack of RA81s from another lab. The TU58 might be a bit cramped for a full-on bootloader with all kinds of network support at 256k minus whatever else needs to be on there for the machine to boot to the console. However, if it can then read a more complete loader from the RL02, or even a miniroot... Hmmm... Very Interesting... --Steve.

Sad Day need help on replacing ASR35 and IBM 129 Verifier

by PLancashire＠columbia.com

I lost (in addition to lots of old computer items) two things I'm trying to get information for my insurance company on. The first is a ASR35 that was 'loaded', over the years I had converted a TWX ASR35 in to on that had every option you could think of. I just did a search of Google, and could find almost no references to it, sad in its own right. I also lost a ASR 38, but that's for another time. The other item destroyed, was a IBM 129 Punch card verifier. A 129 is a 29, with the ability to verify previously punched cards. It also could be used as a card reader. Mine had that option. Both were very clean, low usage. They both were 'backup' machines that in the case of the 129, had less then 100 hours on its run time meter. Both had full sets of manuals, spare parts etc. The 35 included a never used type unit in the box. So if anyone could help with where I can start to look for replacements, value etc. I would be most thankful. Thanks in advance for any leads -pete

help: Brikon Floppy drive tester

by rigdonj＠cfl.rr.com

Hi, I have a couple of Brikon model 723 floppy drive testers made by Brian Instruments of Fullerton, California. One of the testers that I have has the "R" option. The "R" option is a feature that includes a bunch of flying leads tahat you can attach to various test points on the drive under test and measure various analog parameters. It's shown in the factory brochure and it appears to be a ribbon cable with a small blue box on it and about 8 or 10 individual leads coming out of the box. The leads appear to have banana plugs on them where they plug into the box and the other ends have grabber clips on them. Does anyone have one of these cable/pods? If so can you send me the pin out so that I can make one or can I borrow it long enough to make schematics of it? Joe
