My fault for not fully reading your exhibit registration. Dean told me last night. I need to update the webpage. Was going to reply to my own comment here but you beat me to it.

Re: [vcf-midatlantic] [OT] Early Kodak Photographic Copying Device?

Before photocopiers & laser printers were ubiquitious, there were many curious methods of duplication. See: https://en.wikipedia.org/wiki/List_of_duplicating_processes 1) if you have a paper copy that's a B&W negative, it is probably a Photostat. I found several photostats in my dad's papers. https://en.wikipedia.org/wiki/Photostat_machine Description Both Rectigraph and Photostat machines consisted of a large camera ... After a 10-second exposure, the paper was directed to developing and fixing baths, then either air- or machine-dried. Since the print was directly exposed, without the use of an intermediate film, the result was a negative print. 2) I once salvaged a Thermofax machine. It was a box of BRIGHT lamps and a heated roller. No chemicals required. https://en.wikipedia.org/wiki/Thermofax 3) I once had a little darkroom kit with a contact printer which was a tin box with a light bulb inside, a glass top with hinged top. The paper was developed by inserting it into a plastic gadget where a crank turned rollers (via gears) dunking the paper into 3 consecutive chemical trays. 4) The way these relate to computers & electronics: several of these processes were used for chart recorders and "oscillographs" (oscilloscope where a light beam was bounced by moving mirrors onto a screen, or film). High resolution charter recorders avoided pen lag & overshoot by using a galvanometer and light beam onto light sensitive paper. I think HP used IR onto heat-sensitive paper similar to today's receipt paper. -- jeff jonas

Atari exhibit(s) at VCF East
by Evan Koblentz 20 Feb '19

Since there will be a huge UNIX exhibit anniversary exhibit, there should also be a huge Atari computer anniversary exhibit. Pete opened the door by registering his Atari exhibit just now: http://vcfed.org/wp/festivals/vintage-computer-festival-east/vcf-east-exhib… I encourage all Atari exhibitors to work with Pete and to perhaps make your own off-list discussion method for coordination. It would be fun if, in one of the exhibit rooms, we have a whole long row of Atari facing a whole long row of UNIX systems.

CNN story about Apple IIe found in attic

Touching, nostalgic story about a man finding his (working) Apple IIe in his parents' attic after 30 years, along with a letter that his deceased father wrote him: https://www.cnn.com/2019/02/17/tech/30-year-old-apple-computer-work-trnd/in… Some great comments in the twitter feed, too.

All, Do any of y’all have any idea what this is? https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2F… It looks like a direct contact plate exposer, to me, but I’m not sure. Very pretty. - Alex
