It seems to be different from that used by the USA legal >system, in which a copyrighted manual IS an embodiment of intellectual >property, as is any reproduction, particularly scan or photocopy. ------ My point exactly; a manual, and especially a scan or copy are the embodiment, not the IP itself; I think you'd have trouble copyrighting a copy of a copyrighted work. We were talking about "attribution;" if I were to quote one of Mark Twain's many witticisms it would still be attributed to him, not me. So "attribution" of a copy to one of several other copies of the same thing seems rather meaningless except as a matter of courtesy and I don't understand why some people seem to think it's useful and important information. But, having said that, you're absolutely right: the purpose of the Internet these days is indeed largely "the free sharing and exchange of other people's intellectual property," and a large part of that IP is specifically meant to be shared and exchanged. m

NGEN B26 - CTOS floppy? Was Convergence Technologies Series 186

by Michael.Elrick＠telecom.co.nz

Hi, Your posting was from quite a while a go but I thought I'd try dropping you a line. I was looking for some information related to the B26 hardware but there's not too much. I wondered how you got on with your one? I recently picked one up but I suspect that the floppy/HD card and perhaps the HD to be faulty so I can get to the 'L' prompt where it stops. The 'L' is where is checks for a floppy drive. I have changed what I can eg cables, floppy drive, cleaned it out etc but it does not want to go further. I picked it up with a pile of manuals, software and system disks. Did you ever get yours going? Any idea where I could source spares? If all else fails do you know someone who has an interest in the B26 and BTOS or CTOS? Michael Elrick.

PDP-11/05 core questions

by mcguire＠neurotica.com

Ok, I decided to dive into the PDP-11/05 a bit tonight. First I'm trying to make sure I have all the right boards for when the time comes to assemble the system. I have the two CPU boards (M7260 and M7261, actually three of the latter!), the M9970A SCL connector board, and two M930 terminators...so now I need some memory. The stamped silver tag on the side of the chassis says "11/05 SC" which I assume means it's got an 11/05S backplane in it. This assumption is supported by the board location sticker inside the card cage, which is labeled for a 16K core subsystem (H217, G114, G235, M8293). The problem is, I don't have that core subsystem...I have enough boards (in multiple copies) to put together an 8K subsystem, using H214 (or H215?), G213, and G110 boards. My question is, will this subsystem function in this backplane, or is the 11/05S backplane only compatible with the higher-density core subsystem? There's one other problem...The circuit breaker on the rear of the chassis is physically damaged. Does anyone have a spare one kicking around, or know of a currently-available replacement that I can order >from a component distributor? Thanks, -Dave -- Dave McGuire Port Charlotte, FL

Parametron/PC-1?

by mwichary＠gmail.com

Does anyone have any information (especially photos) of the Japanese Parametron/PC-1 machine, or any book/periodical sources where I can find some? Here are some links I found, but I was hoping for more: ? http://www.thocp.net/hardware/parametron.htm ? http://www.ipsj.or.jp/katsudou/museum/computer/0080_e.html ? http://www.ipsj.or.jp/katsudou/museum/computer/0180_e.html -- Marcin Wichary Sr. user experience designer, Google Graphical User Interface gallery >> www.guidebookgallery.org

Decmate

I >haven't tried it on mine yet. > Do you know what the control sequence and data format is and/or what manual documents it? I though the sequence went VT78 (in VT52), DECmate/VT278 (in VT100), DECmate II (in big PC like case), DECmate III (in little PC like case), DECmate III+ (same)

A. C. Clarke has passed -> 2ost century visionary

by c.murray.mccullough＠gmail.com

I agree to some extent with Rick. Nevertheless I think no matter what came to past or didn't the masses have come to accept, sometimes reluctantly, the technocracy we live in today. Even those in the developing world are being engaged in the communications and technical revolution. A. C. Clarke showed us that we need not fear the unknown.

Expanding RAM on Data I/O 29B

by mardy＠voysys.com

I have a working Data I/O 29B with a 128K RAM module which only had half of the DRAM sockets populated. From looking at the schematic, it seemed that by simply populating the remaining DRAM sockets that I would bring the module up to the full 128K. I tried that, but the 29B still only reports 64K of RAM. What did I miss? -Mardy

FTGH: SGI 14" monitor (yes, really) - Yorks UK

by listmailgoeshere＠gmail.com

Hi cctech'ers, I have an SGI 14" monitor here which needs a new home. Yes, it really is a 13W3 monitor this small. Type number is Wyse WY-851, and it has the "old style" SGI logo plus the "Silicon Graphics" wording on the front. I can ship this anywhere in the UK (except highlands, islands and NI) for 8 GBP, you pay PayPal fees. I'll ship internationally if anyone is desperate for it, but it's likely to cost you more than $100US, so you'd have to be pretty keen. If it's not gone fairly soon it'll end up going to the recycler. Please drop me a mail if you'd like it. Ed.

Pantone or RAL reference for the blue color of the IMSAI

by c_habib＠bluewin.ch

Thanks for all the interesting anectodes and tips in answer to my question. As i am restoring an Imsai, before asking my local car paint shop to repaint the cover, i was hoping to get the exact color reference from someone of our group. Just for the sake of exactitude of the restoration. It would be marvelous if Sellam Ismail would give us beside the address of his friend the reference of the paint he used, or was it a "decorative" paint far away from the IMSAI blue? Living in Switzerland sending the cover to California would be a rather expensive exercice! Incidentally yes i tend to agree that the original paint was powder coated (at least on on my cover). Kindest regards Charles

S100 archive?
