Cold Fusion, Infinite Capacitors, and other Suppressed Technologies...

by tomj＠wps.com

We're all wrong! Tantalums don't "fail" -- that's not zero-ohms you measure across the two mangled pins -- it's INFINITE CAPACITANCE! I estimate my little 47uF/35VDC tant must now be, oh, a TF or more (teraFarad). Of course it blows the 5amp fuse in the power supply! The TC is measured in YEARS... There's no other explanation possible. None. I am not listening to you.

missing pages from DF32 manual on bitsavers

by ethan.dicks＠gmail.com

Does anyone have the last few pages of the DF32 (not DF32D) manual? I was specifically interested in the board used to display track selection, etc, for the diskless tests. IIRC, it's on like page 6-41, and the copy of the DF32 maint manual on bitsavers only goes up to 6-37. Thanks, -ethan

tractor-feed paper sizes?

by eric＠brouhaha.com

Does anyone happen to know anything about obscure sizes of tractor-feed paper? We've now got the console typewriter of the PDP-1 at the Computer History Museum working correctly. It is an IBM Model B electric typewriter modified by Soroban Engineering for use as an I/O device. Soroban added an encoder and a decoder mechanism, using switches, solenoids, bails, etc. There was a bent leaf switch contact that resulted in incorrect character codes on input, and two stuck solenoids that resulted in incorrect characters typed. Anyhow, the typewriter will accept individual sheets, but it also has tractors for continuous forms. But the distance between the sprockets is approximately 13 1/8", which is narrower than the sprocket spacing of standard line-printer paper. A Google search reveals plenty of places that sell 9 1/2" wide or 14 7/8" wide continuous forms, but are other sizes readily available? Thanks!

HP 7908/7912 head locking

by Arno_1983＠gmx.de

Hi everybody, the information technology "museum" at Erlangen University (for which I work part-time) will be aquiring two HP 1000 systems in the near future, an A600+ in a 16-slot cardcage with a "piano-seat" disk/tape unit (7912P) and an A700 in a big cabinet with rackmount storage (7908 and 7912). I'd really like to have them arrive undamaged. As noted in the archives, there should be a shipping lock on these drives (see http://www.classiccmp.org/pipermail/cctech/2003-April/013531.html). We've already received the documentation for the system, but obviously the now important parts (Disc Drive Installation Manuals 07908-90902 and 07912-90902) are missing. Some Google activation brought up several sellers of used drives along with a few classiccmp threads, but no online copy of the manual. Can somebody please tell me how to properly prepare the drives for transport? From what I read here, they're not very reliable anyway, but one doesn't need to make matters worse. They're in a building just across the yard, but as I always need to coordinate three parties to do something there, it would be best to know what to do *before* actually poking around in the cabinets. Your instructions (or redirections to web resources) will be sincerely appreciated. -- Arno Kletzander Stud.

Abandonware site charges for downloads

by vcf＠siconic.com

What do you folks make of this site? http://free-game-downloads.mosw.com/ That have a bunch of software for download. Some of it is Abandonware. Or at least it's claimed to be Abandonware. How do we know it's Abandonware? They have nothing on their site (that I could find) that confirms that these are abandonware, and there are thousands of titles there. They want money if you want to download anything. I can understand them wanting to cover their costs, but this seems pretty sleazy to me.

Liberator 220.

by williams.dan＠gmail.com

I now have 7 of these liberator 220's. I don't have the cables yet to test them, or even know if the cables I have coming will work. Looking inside the cases they have 2 full height drives in there. They are standard 50 pin scsi drives. The two drives connect to what has to be a scsi-->dssi board. This is making me think that could change these drives for something bigger. But if anyone knows more about these I would love to know. I was wondering if the two drives inside are mirrored or in an array. The arey in a rack all daisy-chained together, unless someone has messed about with it, I thought dssi was max 7 devices. They also have a programmable front panel, with no instructions and just three buttons. Does anyone know how this works. Also does anyone know how the speed of these compare to standad dssi drives. This is going to go great on the 4000/705a. It would be nice if I could swap a couple of the drives for 18gb. Apologies if you read them, I have asked the same questions on both vms and dec newsgroups. Thanks Dan

No, I don't know the actual figures, but the one we had on eval seemed, subjectively, about 2/3 or maybe 3/4 of that speed. It's an HP, but I can't remember the model number either.

I was not the only one unhappy with the results!! When I worked in CompSci, we got a big fast Oce scanner/copier, about 1997, I think. One of those that collects the output internally, safely away from fingers, because the paper goes fast enough to cut fingers off if they're not out of the way. I remember the first print job I sent it, a large A4 manual printed from a PDF file. I walked the length of the corridor to the print room, saw no output, and was slightly surprised -- for about 3 seconds, when a *large* block of paper was neatly deposited on the output tray. > LOL, this (..) is typical "Pete humor".

Ok, I checked. I am that fast back because I remembered exactly where to look :~) I have one before me on the desk. It has the following description: PRODUCT CODE: AC-8528C-MC PRODUCT NAME: CZDLDC0 DL11-W DIAG DATE CREATED: MARCH 1978 MAINTAINER : DIAGNOSTIC ENGINEERING AUTHOR : DAN CASALETTO Don't be fooled, it is printed on Letter format, 2-sided! Only the first 6 pages are one page per side, all the following pages are scaled: 2 pages per side, thus 4 pages (or images) per sheet. The first 6 pages describe the load and start procedure, the switch bits to get special functions, etc. just as described on my site. The scaled pages contain the assembly source (output) listing ... they are numbered from "seq 0012"up to "seq 0103", and I checked, the numbering is not octal but decimal! If there is interest I could start to scan these to 600 dpi PDF files, but I have a stack of approx 20-30 cm high, so that will be a lot MB's! I could start making a list of what's in the box.

I could go and check ... AFAICR I also have a stack of listings that belong to XXDP programs.

Later diagnostics use a common set of "switches" to tell them whether to halt on error, loop on erro, produce lots of reports, etc; alsmost all diagnostics have specific settings to determine what they do in detail.

Who Made/Makes the World Smallest Harddrive

Problems reading older disk on newer drive

by vcf＠siconic.com

I think we've discussed this before. Sorry if we're re-treading old ground. I'm trying to read a disk an old double-density PC formatted disk on a high-density drive. I can read the directory and certain small files just fine, but any files that are larger than a few sectors (or perhaps that span a track) return "Sector Not Found" errors. What is the deal with that? This is under DOS 6.22. Is there a way to get DOS to recognize that this is a double-density disk and to perform whatever internal magic is necessary to read the disk properly? Or is this an issue of hardware? -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

Our hobby in The New York Times -- sort of

by RCini＠congressfinancial.com

The intellectual property issues would be key for me, too and could have been dealt with in a few sentences. As far as the crappy-versus-good title licenses, I would offer up that the final choice of games comes down to (1) which IP owner you could locate and (2) successfully negotiate with. There's the firm...Tulip I think...that from what I've read seems to be ready to come down hard on anyone using abandoned Commodore properties for commercial gain. It's been a long road of failed owners, but I believe Tulip owns the Commodore trademarks and IP. I can't say for sure if they own the designs for the 6510 but I would assume that they bought a "package" of IP from Gateway, who bought it from Ascom AG, who bought it from the Commodore bankruptcy estate for $5mm (IIRC). There might be another name in there after Ascom, but I can't be sure. I think that Tulip uses the Commodore name for things other than computers but owns all of the goodies that's of particular interest to this group.

Sated geek that I am, I'd love to read an in-depth article on the intellection property issues: Did they get permission from the CBM's heirs? Who got the 6510's IP rights? What about the software, was that easy to license? Why do so many of these cheap emulators license lousy titles, as opposed to the extinct top-sellers? - John

my old FIDO CP/M-80 machine running

by tomj＠wps.com

Deciphered the missing keyboard cable and the far, far too complicated keyboard interface (I practically rewired a Cromemco PRI board to be an interface for this lovely Microswitch parallel keyboard -- very hardware-head), soaked & washed the mouse poop off the floppy cable, repaired the section of conductor #50 nibbled by said rodentia, picked a system floppy at random (DSSD), typed "b" at the prompt... READ ERROR. Pulled a SSSD system disk, booted fine! Some fiddling, I can't read any sectors of side 2. That I will figure out. It does figure out sidedness. Found I have bunches of blank NOS DSDD floppies, not one SSSD blank! So no formatting etc. So I ran all the progs on the system disk (wordstar, sid, pmate, stat, etc) OK. Since I've got a bunch of SSSD system disks, I stuck another in the B drive (a sssd drive, since mice ruined the orig. drive), and ran MBASIC 5.03 off it. Man, the B drive spindle bearing is trashed; it's conversation-level loud. The G and right-shift keys on the keyboard don't work, and the RETURN key sends a garbage character then CR (but Control-M works so I can do stuff). I need to fix the "G" key, figure out the serial port stuff, then I can export the SSSD diskette contents. Once I fix the DS thing I'll do the other non 3740 format diskettes. I don't know yet what order I'll do things in though I will probably get one of the serial ports working to make sure. Luckily I have ZAPLOAD (bin to hex) and telink (telecomm) progs on the system disk.

> Tulip owns the Commodore trademarks and IP. I can't say for sure if they > own the designs for the 6510 It doesn't really matter, as no one building a product today would use any portion of the original 6510 design that is subject to intellectual property protection. The DTV 64-in-a-joystick, for instance, uses a new 6510-compatible HDL implementation. AFAIK, the only part of the original 6510 design that would be subject to intellectual property protection now would be the actual mask designs, which might (or might not) be copyrighted. No one in their right mind would try to make new 3 micron NMOS processors today, and the mask designs are not relevant to new redesigns.

Who Made/Makes the World Smallest Harddrive( Winchester)

by mmcfadden＠cmh.edu

Actually in 1975 or 1976 one of my fellow graduate students, moving to Beaverton Oregon to work for Tektronix, was trying to move some early disk drives and was asked by the movers what they were. Home furnishings were readily moveable but not office stuff. So he put them in washer and dryer boxes and the movers were happy to move them. They had been used as end tables in his living room up until them. He also built the first Altair I ever saw. Andy said > >My experience of early hard disks was with the ICT EDS-4 which stored 4M 6-bit characters (ie about 3 MB) - the >(exchangeable) disk pack was close to the size of a complete PC ... the drives were referred to as "washing machines" >because of their size and appearance. (and the controller was about the same size also). The IBM equivalent was, I >think, the 1311 ... the 2311 being equivalent to the ICT EDS-8 (which had twice as many tracks as the eds4 but was >otherwise identical) Mike

Resurgence of the C64/Tulip/Jeri

by RCini＠congressfinancial.com

Here are a few Web links that talks about Tulip and the C64. Some are bit old, but worth a read: http://www.pcworld.com/news/article/0,aid,111556,00.asp Article from 2003 that gives an overall look at the relationship. http://www.tulip.com/news/article.asp?nid=109 This one raises as many questions as it answers. It only speaks to enforcement for the unauthorized use of the Commodore name. http://www.tulip.com/aboutus/corp_article.asp?nid=145 This is an interesting link, too. Although it's in Dutch, the product looks remarkably similar to the one Jeri is holding in her hand. Interestingly, in a note on Ruud Baltassen's site indicates that Tulip doesn't mind people using the Commodore name in a non-commercial setting, I guess acknowledging that in the time between when it purchased "the name and other assets in 1997" and 2003 when they talk about developing game products for the PC (like the Atari Anthology program, I'm guessing -- old games running on a new machine using an emulator), a lot has happened. The problem is that no one ever says what "other assets" is. Rich

FET Cross-reference - a bit off-topic

by nbreeden2＠comcast.net

I'm in the middle of some repair work on an older Heathkit O-Scope model IO-102, the vertical board uses an N-Channel FET (Q1 - EL131 - Heathkit part number 417-241) which has become very thermal. I picked up a replacement >from a local electronics distributor however the crossed NTE part simply doesn't work in the circuit. (NTE cross shows an NTE133 as the cross for the EL131). I've tried a couple NTE133s and an MPF105 as well, all work the same in the circuit but don't work correctly. Does anyone know of an exact EL131 replacement, know if the ECG312 really is a good replacement or even better know where I can get a Heathkit replacement part. Digikey, Mouser etc. all don't recognize the EL131 part number. Thanks -Neil

Macintosh collector groups?

by sml49＠comcast.net

Michael.. You might try posting them in the both the "free" area and "computer" area on Craigslist (www.craigslist.org); that might work. The IIsi has pretty much no value - ie: I doubt anyone would pay anything for one beyond the cost of shipping unless it has one or another of the more interesting PDS cards or adapters (does it?). I have quite a few si's that I've picked up at the local recycling depot. The 7200 is a more useful machine which is still upgradable. What comes with them by way of peripherals/ keyboards/ old sofware/ whatnot? I've been keeping a double handful of older Macs around here and the software to run 'em just in case some day down the line when I'm old and gray I suddenly have the urge to run PageMaker v. 2, or even Excel 1.04 (all 170K of it)...or the original MacPaint.

cool HP-IB find

by rigdonj＠cfl.rr.com

I went to one of my favorite scrounging spots today and found an interesting disk drive with a HP-IB inteface. The drive was made by IEM and it has two 105Mb removable cartridge drives in it. It looks like it takes Syquest disk cartridges. Does anyone have a couple of spare Syquest 105 mb cartridges to spare so I can try it out? Joe
