How to tell differential scsi drives and cards apart

by teoz＠neo.rr.com

Is there an easy way to tell if a SCSI controller or HD is LVD or HVD? My understanding is that HVD was the first type used and was just called differential F/W and then LVD came out so the old standard was then called HVD. I have some SUN Symbios 22802 cards coming in I wanted to use in a SUN Ultra Sparc 5 and I think those are HVD (advertised as just differential and I didn't think to cross check). Everything I have is SE/LVD.

PDP-8 front panels

by pontus＠Update.UU.SE

PDP-8s has been used for just about everything and have almost as many different front panels. This is one of the more esoteric ones I've seen: http://www.flickr.com/photos/joachimschwanter/414790437/ Is this a one off custom build? Rebuilt by a PDP-15 lover perhaps? Appearantly it was showcased at VCF Europe in 2008, maybe someone was there and can shed some light on it. Hope this is tech enough for cctech :) Cheers, Pontus.

I don't collect PDP-10 stuff. I collect PDP-8 and PDP-11 stuff (along with some VAXen and other DEC things). Johnny Eriksson is also in Stockholm, but I didn't know he had taken care of the KA and KI systems. And as far as KI systems goes, Peter Lothberg still have KICKI, so Bygg don't have all of those. Admittedly a technicality since if they aren't stored at the same place, it's still in the same town. So on a "world" scale, they are perhaps all "here". But maybe Rich Alderson meant just "near" as in physically not far from, even if not in his possession. The only KA-10 system I know of, by the way, is KATIA, which was owned by Stacken. I had/have an account on it, but I don't think it's been powered on for close to 20 years now. (The name KATIA is a pun in Swedish, by the way.) >> > Oh. I didn't mention that, did I?

A few newb/background questions about the XKL TOAD

by madcrow.maxwell＠gmail.com

There's recently been a lot of talk about the XKL TOAD, and I, as an interested lurker had been holding my tounge, despite having some questions. No more. 1. How does the XKL compare with the Jupiter? Given that they both had features like an extended address space, was the XKL basically a "if DEC won't build it, we will" type of thing? 2. What the difference between the XKL TOAD and the various SC systems? Was SC a reseller/packager/intergrator or did they have their own seperate "Super KL"? 3. Does KLH10 support any of the XKL extensions? 4. Do the freeware copies of TOPS-20 floating around the internet have any support for these extensions or were those proprietary to the copies of TOPS-20 that shipped with TOADs? Thanks for answering this barrage of silly questions, Mike

As I mentioned the other night, I'm peripherally interested in an FPGA-implemented -10, but I have a definite budget - I'm willing to roll a lot of my own hardware (loose parts, soldering, etc), but I really can't justify more than a few hundred $$$ in total. I certainly can't assist with the VHDL-end of things. Once things get past the experimental stage and it's booting TOPS-20, I'm likely to be more interested. My requirements are pretty loose - if it runs one of the extant compiled versions of MDL Zork, I'm in. -ethan

Old Software Rights

by cclist＠sydex.com

On 15 Jan 2009 at 12:40, Paul Koning wrote: Copyright these days is a LOT longer than 30 years. And even back in > the 1940s, it was 28 years initially plus another 28 years if renewed > (and if the copyright was still in effect in 1976 then the new long > terms would into play, if I understood right) -- so if you have a > copyrighted work from 1940, it's in the public domain today if it > wasn't renewed, but it's still copyrighted if it WAS renewed. Copyright is implicit in all works produced today, whether or not stated. Almost all software published during the 1970s has a copyright notice embedded. After the Uruguay Round of the GATT talks, copyright for works published after 1923 whose copyright was in effect as of the URAA is 75 years, later extended to 90 by the Sonny Bono Copyright Extension Act (yes, he, or rather his widow, of the other half of Cher. Reportedly, Mary wanted to make copyright perpetual, but was informed that such a move was distinctly unconstituional). Read about the law at http://www.copyright.gov. Rules outside of the US may be substantially different. In particular, after the fall of the Soviet Union, legislation was passed in the US to allow works of Soviet origin to be removed from the Public Domain (so-called "restored" copyright. Who says you can't put the toothpaste back into the tube?). However, they may still be freely copied in Canada. Bottom line is that there is no such legal entity as "abandonware" and you promulgate the idea at your own risk. While economic damage is part of civil actions brought by copyright holders, it is not the whole picture. Unlike patent infringement, copyright violation in the US is a criminal offense under the DMCA. Just because no one seems to be using IBM 5160s to run Harvard Presentation Graphics from 360K diskettes does not make it legal to copy and distribute it. It's not up to the infringer to declare whether or not a work has any value. So you may have to wait until, oh, 2075 or so before you can legally hand out those old copies of Lotus 1-2-3, assuming that our Congress isn't goaded into action by the Empire of the Mouse again. As a musician, I'm continually frustrated by publishers of old copyrighted material (some stuff going back to the 1930s) who declare a work to be "permanently out of print" and will not authorize a copy (for a fee) nor provide me with a copy that they created from their archives. Currently, the only resort left is to pick some other work. There's nothing in copyright law to force the owner to publish or support his works, nor give permission to copy. And the notion of "Fair Use" is a very slippery slope--if you guess wrong, you're fully exposed. Cheers, Chuck

NCCC - Sunfire V100 / Solaris

by quapla＠xs4all.nl

Tom, Best way is to install Solrais 8, 9 or 10. Then install the SUNWlomu, SUNWlomr & SUNWlomm packages followed by patch 110208-22. Then use the lom tool to manipulate the lom config to your likings. BTW, the patch has the latest firmware for the lom, so you can also upgrade it if wanted.

"Tyrotek" analog computer

by hilpert＠cs.ubc.ca

I'm currently working on refurbishing a small analog computer from the mid-60's. It has the name "Tyrotek" on the front panel, in the middle of a sine wave curve. (My) web searches turn up zippo about this name (other than some guy using the word as a moniker). The only other clue to a manufacturer is "Non Linear Mfg." in the foil of the printed circuit boards. No model number, no identification plate. While it is smaller for an analog computer and appears to be intended as an educational or training unit, it is built to industrial standards, with a nice sizeable plugboard using standard IBM plugboard wires, fiberglass PCBs, discrete FET-input op-amps, etc., so it's not just some gimmicky thing. Eventually I'll have a web page for it, but right now I'm curious as to it's manufacturer origins. Just a guess, but one line of speculation I'm making is that "Non Linear Mfg." may have been the manufacturing arm of Non-Linear Systems of digital voltmeter fame, and Tyrotek was a subsidiary of, or otherwise associated, with NLS. Comments / clues / recollections?

Commodore Pet 2001 Troubles

by jason＠havnet.net

Dear Fellow Enthusiasts ... Firstly, I must admit to being somewhat of a 'lurker' here reading with great interest the postings and never failing to be amazed at the shear amount of amassed knowledge on the subject. My thanks to you all. Is there anyone here that can help me with a Commodore Pet problem that is really starting bug me !! It is a Pet 2001 32N with a Computhink Pet II Disk Controller Board and a pair of Dual Computhink drives (Model : DKH 642-I). The machine starts up just fine and you can enter DISKMON by typing SYS11*4096 However, upon entering commands like $LOD,1,"FOO" the screen turns to a complete screen full of small squares - chequer board style. Upon the command $DIR,1 the screen briefly displays a boarder around the screen where the directory content would normally appear and as soon as the drive activates the screen turns to chequer board. I have done the usual of re-seating the IC's, and I am hoping this isn't failed ROM. Another clue maybe that for some reason, when the drives are activated, BOTH drives activate together, which obviously they shouldnt. I haven't yet gone to the lengths of scoping the control lines but will start there tommorrow evening ... Does this sound like a problem that anyone has enountered before? Are there any 'Petsperts' out there that could help get this machine back on the road? Thanks in Anticipation Jason Fitzpatrick www.ComputingHistory.org.uk

Failed bit on 11/05 core memory

by toby＠coreware.co.uk

Alas having got my 11/05 working, its developed a problem. Bit 5 on the lower 8KW of memory (it has two sets of G110/G231/H214 8KW cores) has failed and is always set to 0 Does this indicate a failure in the X/Y drivers? I have a spare set of G110/G231 cards, so I'm guessing swapping out the failed card will provide me with an immediate fix, although I would like to get the existing card repaired. How is the base address of core memory set? Are there jumpers on the boards or is it position in the backplane that determines its location? Thanks, Toby -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Flexicord cables get bent... and stay that way

Well you're not alone, apparently. A company called E-Filliate issued a new series of USB, HDMI, Cat5, S-Video, and composite cables called Flexicord at CES this year which will bend -- and stay -- in any position you please, thus eliminating that frustration you must feel every time you plug in your camera or hook up your high fidelity sound system. The cables act like pipe cleaner or Gumby, so you can twist and shape them as you please, though apparently Pokey had to be killed and dissected so the technology could be obtained.

HVD SCSI Tape library

by jws＠jwsss.com

I have an elder setup I would like to plumb with cables, but do not have all I need. It is a tape library with 2 wide connectors, and an Adaptec 2944 in the host. I am thinking of a 3' or so wide cable (68 pin) with 3 connectors that are male, and each end with a female connector. I can terminate it at each end with the terminators I have, since the controller I have puts out termpwr. Any suggestions or sources or ideas. Anyone have such a beast to spare? thanks Jim
