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

wanted: Votrax PSS manual

For what it's worth there is a manual for the Votrax Type N Talk at the URL below, I believe they used the same speech chip (SC-01). Crap, I had a Votrax PSS about 4 years ago and sold it for pennies on the dollar! http://members.aol.com/itsancientpics3/votraxmanual.htm There is also a neat piece of DOS software to read the screen through a PSS at: http://park.org/Guests/Trace/pavilion/dosshar1.htm Sorry, that's all I can come up with.

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.

So I sent it to cctalk instead, with the same account... and my message still never showed up. (I guess classiccmp.org is rejecting all comcast mail as spam or something nasty like that) So now, I'm sending it through hotmail, and I HOPE it gets through...

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".

Old Unibus PDP-11 XXDP diagnostics

by GOOI＠oce.nl

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. Xmas is coming :~) - Henk. -----Original Message----- From: cctalk-bounces(a)classiccmp.org To: info-pdp11(a)village.org; General Discussion: On-Topic and Off-Topic Posts Sent: 21-12-2004 17:27 Subject: Old Unibus PDP-11 XXDP diagnostics Does anyone have any info/documentation on the XXDP diagnostics for older PDP-11 systems and peripherals? I'm looking in particular for the 11/40 (11/35), RK05, DZ11, RL02, MM11 core memory, RX01, RL01 diagnostics. I have found some info on Henk's site, but would like to know if anyone has a comprehensive list and hints on how to run these, what the output means, how to answer the prompts, etc. I have created RL02 packs with XXDP 2.5 and XXDP 2.2 and I can boot and run stuff from these packs. It appears that the 11/40 diagnostics are on XXDP 2.2, but not on XXDP 2.5. I have an old 1976 DEC field rep troubleshooting guide that refers to various MAINDECs, which seem to have been the diagnostics prior to XXDP. Is there a list somewhere showing what the XXDP equivalents of the old MAINDECs are? Any help would be appreciated. I want to exercise my 11/40 and attached peripherals and see if any subtle gremlins are lurking anywhere within. Everything appears to be working perfectly with the exception of one of my three RK05 drives that I knew was problematic. Ashley
