Remembering the Cray-1

Another Seymore Cray story

Apparently the French atomic energy agency had a brand new CDC 6600 that refused to operate correctly and the service guys from CDC had been unable to locate the problem. The French government was threatening to throw the machine out, so CDC sent Seymore over to rescue the machine. After looking at all of the tests that had been performed by the techs, he closed himself in a room (not with the computer, and with no schematics), emerging a few hours later to tell them that the problem was a particular transistor on a particular board in a particular part of the machine -- and he was right. When asked how he had arrived at the solution, he said it was the only possible answer given the test results and the structure of the machine. His understanding of the machines he created was legendary...

Sony renounces rear-projection TVs

William K Kelley

Bummer

From what little information has been posted, its not clear what Sony is killing. Are they killing just the LCD rear-projection units or the SXRD rear-projection units too? Very different tech and the SXRD tech is also used in their front projectors. Are they gonna kill the front projectors too? And where are the large (60-70") LCD panels to replace the 60-70" rear-projection units? The whole point of the rear-projection stuff was to provide affordable large screens. The largest LCD I've seen at Crutchfield's is just 57" and is double the price of a 60" rear-projection unit. And then there is the question of picture quality -- the SXRD tech results in no discernable gaps between pixels whereas LCD (and plasma too) have a decided "screen door" appearance. But I guess too many people are buying their LCD panels because they are panels and look "cool" rather than for their picture quality. OLED looks great, but its going to be awhile before we see 60-70" panels. Hope my SXRD rear-projection system holds up until then...
