Computing the old way - Is it a thing of the past?

I recently had some old (1940s to '70s) 8 mm family movies scanned digitally. The service cleans the film and uses a wet-gate process to reduce scratches. They scan each frame digitally at HD resolution (1920 x 1080) using even LED illumination. They scan the entire film edge-to-edge. Many old cameras exposed the entire width of the film while the projector only showed the majority of the middle, so you see more image than ever before. I asked for a digital movie file for editing, so I sent them a hard drive. The results are astoundingly dramatically better >from what you got from an old projector. No playback jitter >from worn sprocket holes. Bright, even illumination. It's far better than the film-to-VHS transfer I paid for in the early 90s. (Private YouTube example links available on request.) All this for a dime or two per foot. I'll be able to edit digitally and provide family members with DVD or Bluray copies. The same is true for restoration and duplication of old family photographs. With a digital process, you can undo damage and easily multiply copies. As with the classic computer avocation, it can come with regrets, too. I wish I would've rescued 1930s family films from a distant cousin who passed away a decade ago. I had a VHS copy of some of his films, but not the originals. - John

Data General Dasher D200 Manuals

by steve＠stephenmerrony.co.uk

I've looked in all the usual places and can't find any manuals for the D200 - does anyone have a scan? I know there are manuals for the later D410 and D411 floating around - but I would like to get some definitive details on the D200. (Also - still looking for any help with the MV/2500...)

isn't this sort of old news/

by jws＠jwsss.com

not that they don't have a large collection of old software, but the gee whiz nature of the blip seems a bit uninformed http://tech.slashdot.org/submission/2601751/the-internet-archive-is-now-the… Don't need a huge thread about how noone reads slashdot, they are just usually the conduit that provides the news. original article here http://paritynews.com/web-news/item/974-the-internet-archive-is-now-the-lar… and they are so proud of collecting the documentation too. Maybe this is different than bitsavers mission, and larger, don't know. Jim

I find hardware and system software (operating systems, database managers etc) equally interesting. Actually, my view is that they are to a great extent two different incarnations of the same thing: The hardware is a physical machine that executes programs, the operating system is a kind of virtual machine which executes user programs. Then there is virtual machine software, that is also very interesting. I wrote a very simple operating system once in my career, now I am playing with writing another one in my spare time. Some day I will most likely also design and built my own processor, whether with discrete logic or an FPGA I am not sure, perhaps both. And then the physical experience of an actual old machine running is something special, quite like driving an old car or riding on a steam train. /Jonas

Computer ASCII Text Art from the 1970's

So how often do these original CDC "Mona Lisa By the Numbers" posters come up for sale? Or the old circa 1960 Calcomp 30-inch plotters? - John

First, thank you to everyone who replied. I got at least something out of every post so far and that's no small thing. I must have misread something along the way as I thought the /23 had separate I/D spaces. Good thing to have that correct now. I'd not mind getting one to run it for it's own sake but to get it thinking it could do something it couldn't would be much more annoying. Thank you to the pointers to additional docs - the field guide as especially nice to find as I'm still learning my way around the DEC module names. The chassis information was quite helpful as well. As for why, well... I graduated HS in 1982 & took a short detour into the Army so I missed a lot of the "glory days" of some of the things on this list. I started with micros and as a student the closest I got allowed to the Vax was a login prompt. The first (non DOS,OS/2,Windows) software environment I really got to know well was Unix and then learning of Lisp & LispM's. These days emulators are fun, capable and perfect for most home users - I certainly would not have the room or power budget for a CADR or PDP-10 or 11/780 in the basement! I respect those who can but, alas, I'm not able to do that in my current rental But I do have the room and enough of a toy budget to slowly put together a classic PDP-11 system of the later /73, /83 or /93 type & run the kind of software I'm familiar with on it. Might even try to see if I can back port Franz lisp and to it from the 4.2 distribution just to give myself a reason for it. Ultimately I'd like to have a small collection of real classic hardware - a Symbolics XL1200, a Vax (or Vaxstation) 4000 & a PDP-11. I'll work on that last one for now and deal with emulation for the rest :) Thanks again to everyone, William -- Live like you will never die, love like you've never been hurt, dance like no-one is watching.

Warning: fake ebay 'second chance' offers

by tmfdmike＠gmail.com

Folks, I was an underbidder on the System/360 panel that recently went on ebay. This morning I received an obviously fake 'second chance' offer email. The interesting part is that the sender had clearly done some research, as ebay has not exposed your email address for many years, precisely to prevent scams like this. Since my ebay ID is 'corestore_org' it's not too hard to google and find an email address for me; they clearly did so, as the email correctly associated my email address with my account name, exactly as a genuine ebay email would. I don't think anyone here would be taken in by such for an instant, but be warned all the same; someone is being 'active' with scams tailored to our interests. The email claimed to originate from 'ebay at ebay.joe211.info' and sought a reply to 'jrengineer70 at gmail.com'. EDIT a google reveals several other scam emails using this email address. It never struck me before, but of course ebay doesn't even show underbidder *account names* any more; they splash them with asterisks and display them as x******x. Yet the scammer knew my full ebay ID, my correct email address, AND the amount of my underbid. Someone *must* have cracked the ebay database... Mike http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother. Not for millions, not for glory, not for fame. For one person, in the dark, where no one will ever know or see.'
