Side issue Bevatron PDP-8 Classic & teletype control? and great print/scan cheap

by COURYHOUSE＠aol.com

Any Northern Calif folk (current or Ex) that might have been around the BEVATRON - Ok this thing had pdp-8 computers ( the classic first model rack mounted) and teletypes hooked to it I am finding very little info on it... Just scanning stuff on Crocker's Cracker (the 60 incher) here tonight and putting together blueprints. if you want a from the store solution try the hp 7612 scans and prints in excess of 11x17 on sale less then 200 bucks! I highly recommend the Microsoft labs stitcher program. I have had some scans with some pretty crappy alignment and I made one giant beauty of a blueprint. The 7612 also prints beautiful 11x17 color prints to go in displays here for the museum.

Front Panel Progress - 8/e (type A & B) e/f and 8/m Update

by rodsmallwood52＠btinternet.com

Hi Guys! I now have the (hopefully) final artwork for all four PDP-8 front panel variations. I have made up a display file. The file shows the combined black positive master for white lines, white text and logos for all four designs. There can be up to five layers and hence screens for each panel. The file is in .svg format because I use Inkscape to do most of the work. Let me know who would like a copy Regards Rod

Somewhat OT: RIP Robert "Bob" Hall, Jr. (Jan 5th 1957 - July 28th 2015)

by drlegendre＠gmail.com

Friends, I know some of us knew Bob Hall, an amazing character, who spent the last decade of his life crusading for the restoration of US manufacturing and railing against the perils of the Giant in the East - among other things. Sadly, I learned only today that Bob passed away on July 28th, 2015, due to intractable pancreatic cancer. Our friend was a tender 61 years in age. You can find a page, with an obit here: http://tinyurl.com/paspfax Rest in Peace, Bob.. your 'dispatches from the front' will be missed. We need more voices like we had known in Bob hall. (It seems all of his content has been removed from FB and YT. Might still remain in archive.org)

9-Track 1/2" Tape Drive Recommendations?

by cctalk＠fahimi.net

Hello All, Recently I came across a complete Pertec interface (card, manual, software, and, cables) thanks to list-member Shaun. Of course what is the point of having an interface if you have nothing to interface it to! So I've been looking at, and learning a bit, about 1/2" tape drives. I've also looked into acquiring one. But before going down this path I wanted to see what pitfalls, warning signs, etc. I should be on the lookout for. I am looking for a unit mostly to experience the tech and to play around with. I do not plan on recovering data from any particular system or format. However, it would be nice if I could setup a system that actually worked for backups of say an IBM AT for demonstration purposes. Having read some old InfoWorld and PC Mag articles I can see there were a number of tape drive manufacturers well into the early 90s. Based on the reviews the Cipher and Qualstar units seem to be well suited for my purposes. Any other brand/models I should keep an eye out for. I know IBM also had some 1/2" 9 track tape drives (9437 and 9438) but neither was a Pertec interface from what I have gleaned. The 9347 used a proprietary interface and the 9348 used HVD SCSI which is atypical. There was apparently a 9348-012 model which used narrow SCSI so should interface with a standard Adaptec card. However, I have not been able to determine if it used standard SCSI commands and could be accessed say with a tape backup program under Windows 9x/NT or DOS. Of course the biggest problem is finding one locally in the LA area. Unfortunately my only resource is eBay and prices there are definitely not hobbyist friendly (not to mention shipping). If anyone has a line on a working drive in the LA area (to save on S&H and avoid the dangers of shipping) or a reasonably priced one elsewhere I'd appreciate it. TIA for any help.

(OT?) Copyright and IP

by thrashbarg＠kaput.homeunix.org

Hi List, This relates to the ongoing discussion about vintage computer software copyright. A year or so ago I did some Beta videotape backups for the Australian Computer Society. They're of keynote speeches at the 10th Australian Computer Conference in 1983. One that I'd like to mention is by Tania Amochev from (then) Control Data Corporation, titled Information Services of the Future. In it, things we now call data mining and Google AdSense are discussed, and the potential of data services in general (this is in 1983). One thing that struck me was the contrast between traditional copyright of material items, and how such ideas don't apply very well to non-material information. I was left with the impression that the idea of "Intellectual Property" is in some ways an attempt to force information to be treated like materials, which is an easy way to put a value information, but also allows it to be hoarded. This goes directly against how information behaves, which is to flow freely. This free-flow of information allows more information to be derived or generated, enhancing productivity and overall knowledge. To quote: "Information is diffusive - it leaks. The more it leaks, the more of it there is. Information is aggressive, even imperialistic. It simply breaks out of its unnatural bonds, the bonds of secrecy in which 'thing minded' people try to lock it. So secrecy, property rights, confidentiality, all enshrined in Western thought and law, are not particularly effective restraints on information." This is not a cry to abolish copyright and intellectual property laws, but to highlight some of the inadequacies of the thought process behind these laws when dealing with high speed, global information. Does anyone have any thoughts? If there was a massive shift in the fundamental philosophy of how information should be valued, where would you like that shift to go? For example, is there a way to pay programmers and similar professions by the quality of their work, rather than just the number of lines of code they write. How do you measure the quality of information? I'll see if I can get permission to have the six keynote addresses put online, because they're all fascinating. Cheers, Alexis. P.S., if this is way off topic, my apologies.

So, what's the deal with DigiBarn?

by COURYHOUSE＠aol.com

I wrote them with an Osborne question as we got a osborne 1 but it was later and slicker and they replied other than that I do not know. Seems we are getting hit with computers with handles on them this month. A RS 4P showed up today! Ed Sharpe archivist for SMECC In a message dated 8/24/2015 3:30:06 P.M. US Mountain Standard Time, ian.finder at gmail.com writes: Hey all- I've always wondered about this. Their website hasn't seen a proper update in years, and it looks like they have a lot of choice hardware donated to them that they may not be maintaining... Is it open to the public? Are people actively volunteering there to make sure this stuff is shown some love and not falling into disrepair? Keeping leaky batteries, capacitors, rust at bay, and doing repairs? Imaging disks? They have some very worthwhile examples of machines but I haven't seen much >from them as an organization in years! I'm sure lots of people would be willing to help if they are under-resourced. Thanks, - Ian -- Ian Finder ian.finder at gmail.com
