Recordak Magnaprint Microfiche Printer Free

by Don

Hello all, I have a Recordak Magnaprint microfiche printer/reader. It appears to be in decent cosmetic condition but I am not sure if it works or if it is complete. This thing used photosensitized paper and some kind of developer to make positive copies of microfiche reels or sheets. https://archive.org/details/TNM_Recordak_Magnaprint_Reader_microfilm_reader… I don't have space to keep this thing, but I would like to save it from being scrapped if possible. Free for pickup near Buffalo, NY. Contact me if interested! Don

What to take to a vintage computer show

by brad＠techtimetraveller.com

Just reaching out to anyone who has exhibited at a vintage computing festival before. After years of only being able to watch others attend the ones that happen in the US, we are finally getting one in BC here. Super excited. I was invited both to speak and to exhibit, and they even got me two tables which is awesome. Like, how do you prepare for these things? What things that you didn't think of going into your first show do you wish you had? I have a pretty eclectic collection, and some really rare stuff (like my Mark-8s) that I'd love to bring but am hesitant about due to the risks of transportation damage and theft (from the car mostly, not the convention itself). Just trying to decide what to bring and how focused to be in terms of theme. Brad

Re: Double Density 3.5" Floppy Disks

by Don R

Maybe I need one of these power cords for my Monroe-Litton 1830 aka Compucorp 485. It might make the calculations more precise? ;) Don Resor Sent from someone's iPhone > On May 6, 2024, at 8:55 PM, Chuck Guzis via cctalk <cctalk(a)classiccmp.org> wrote: > > On 5/6/24 20:25, Fred Cisin via cctalk wrote: > https://www.ebay.com/itm/134706639303 >> include a basic feature for rewinding rental DVDs before returning them. > Of course, you need a pure silver AC cable for those: > > https://www.ebay.com/itm/115970049389 > > --Chuck

Re: Altair 8800 50th birthday...

by Smith, Wayne

"November 19, 1974" is what is written on the "Date of Publication of This Issue" line in Copyright "Form B" (for periodicals) used at the time. The form then states "The copyright law defines the 'date of publication' as '. . . the earliest date when copies . . . were placed on sale, sold or publicly distributed." The form is then signed pursuant to 17 U.S.C. sec. 506(e), which provided for a substantial fine in the event that any false representation was made on the form. There is no reason to doubt the date of publication in the notice. In fact, there is every reason to believe it is correct. In the magazine business it is a routine business practice to have actual publication occur months prior to the "cover date" the publisher places on the magazine. The reason for this is so that the magazines could remain on the newsstands for at least a few months without appearing to be stale. This is particularly the case with magazines published on a monthly cadence. Just as a check, I looked up the publication date of the January 1975 issue of Playboy. According to the copyright registration, it was November 20, 1974. > Date: Mon, 6 May 2024 01:27:28 +0000 (UTC) > From: ED SHARPE <couryhouse(a)aol.com> > Subject: [cctalk] Re: Altair 8800 50th birthday... > To: "General Discussion: On-Topic and Off-Topic Posts" > <cctalk(a)classiccmp.org> > Cc: Sellam Abraham <sellam.ismail(a)gmail.com> > Message-ID: <1726519925.3966543.1714958848839(a)mail.yahoo.com> > Content-Type: text/plain; charset=UTF-8 > > Perhaps After doing the layout work in the November it was perhaps > copyrighted Immediately during layout But it did not ship Until January > Think! back in those days things did not instantly happen and we're instantly > shipped Ed# > > Sent from AOL on Android > > On Fri, May 3, 2024 at 7:09 AM, Sellam Abraham via > cctalk<cctalk(a)classiccmp.org> wrote: On Fri, May 3, 2024, 1:28 AM Smith, > Wayne via cctalk <cctalk(a)classiccmp.org> > wrote: > > > I looked up the Jan. 1975 issue of Popular Electronics in the > > Copyright Office's Periodicals Digest.

And yet, I have a cheap Radio Shack tape degauzer and it erases 3.5" disks just fine. I do it all the time whenever I have one that refuses to reformat. Quick pass over the degauzer and they usually work fine. If not, time to toss them. As for 720K disks I bought a box of new ones (12 boxes actually) several years ago on eBay and expect they will out last me. Especially now that I am moving everything to Goteks. bill

Netflix Series: American Conspiracy/Octopus Murders

by Jonathan Katz

Hey everyone, My better half recently turned this on and also a podcast with the creator/director. They mentioned they visited "someone" with a working VAX 11/780 to get b-roll footage for the movie. Which one of us was it? :D In all seriousness, it would be fun to try and get a vintage copy of the PROMIS software running on something (I assume it was VAX/VMS in its original incarnation, but many other screenshots show SNA/greenscreen implementations.) Cheers, all! -- -Jon +44 7792 149029

I looked up the Jan. 1975 issue of Popular Electronics in the Copyright Office's Periodicals Digest. It was published on Nov. 19, 1974 if you are looking for an actual anniversary date. -W > On Saturday, April 27th, 2024 at 07:14, Bill Gunshannon via cctalk < > cctalk(a)classiccmp.org> wrote: > > > > Magazine cover january, and into 1975 the revolution.
