How many gallons of wrinkle paint? RSWL........ Title: Re: Resurecting ENIAC....sort of Post by: Opcom on November 25, 2014, 10:10:01 PM It would be a beauty to behold. Fine decorations.
A tube type computer is really something else. I was privileged to own an analog tube computer, a small Heathkit. A digital tube computer would be the thing to have, the ne plus ultra, and while bits pieces are nice, I'd only bother if (I was rich and) the thing was complete enough to prove it worked. Indeed, there were small enough ones to fit any living room and blend with the XYL's decor. Long live the remaining vacuum tube computers. Does Neil Young deserve an apology for the following? We've been through Some math together With trunks of cabling Still to come We found compliments of two With tubes forever Long may you run. Long may you run. Long may you run. Although these changes Have come With your glass heart shining In the sun Long may you run. Well, it was Naval Ballistics in 1952 When I last saw you alive But we caught a whiff Of the tubes' decline Long may you run. Long may you run. Long may you run. Although these changes Have come With your steel heart shining In the sun Long may you run. Maybe The Big Boys Have got you now With their wives Sceaming "No more junk, No" Cutting back' on That huge electric bill Until the end of time. Long may you run. Long may you run. Although these changes Have come With your glass heart shining In the sun Long may you run. =========== Title: Re: Resurecting ENIAC....sort of Post by: John K5PRO on November 25, 2014, 11:58:27 PM In 1992 I worked with an EE who designed hardware for the 1950s MANIAC, Los Alamos digital computer after they borrowed time on ENIAC.
Thousands of tube logic gates and latches. Title: Re: Resurecting ENIAC....sort of Post by: John K5PRO on November 27, 2014, 05:58:24 PM Here are some photos of Los Alamos' MANIAC, and Jim Richardson, hardware designer with Nick Metropolis, scientist/programmer. I worked with Jim just before he retired the last time and then died. I don't think there is much left of Maniac I or II, second generation digital computers after ENIAC.
Title: Re: Resurecting ENIAC....sort of Post by: John K5PRO on November 28, 2014, 03:50:28 AM I found these old articles on the ENIAC and the MANIAC and others. You can tell the date of these reports where one speaks of the Cray One as the latest thing. I heard that Los Alamos bought serial number 1 of that machine.
Title: Re: Resurecting ENIAC....sort of Post by: Tom WA3KLR on November 28, 2014, 08:41:10 AM There is a related movie coming out "The Imitation Game" about Alan Turing and the WWII British code-cracking which leads him to develop the first electronic computers in Britain, a parallel effort to the Americans.
http://www.imdb.com/title/tt2084970/?ref_=nv_sr_6 I saw the preview recently and the mocked-up computer they showed appeared to be an electro-mechanical one. I presume though that the movie deals with human relationships and job politics more than technical details.

THAT's what they are putting on display?? Title: Re: Resurecting ENIAC....sort of Post by: RolandSWL on November 29, 2014, 11:25:20 AM Don't forget the new paint. It's now Techno-Art. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
Anybody know what the tube line up was? RSWL......... |
