Welcome to the Computer History Museum channel on RU-vid. We're committed to preserving and presenting the history and stories of the Information Age. Here on RU-vid we offer videos of the many lectures and events at the museum and also historic computer films. We also feature video from our well-known Revolutionaries television series. Be sure to check out the Computer History Museum website for even more information including online exhibits, upcoming events and our collection of computing artifacts: www.computerhistory.org.
Congratulations, dear! Imagine the possibility of tripling your Computer History Museum RU-vid channel and achieving tremendous growth. I have some strategies in mind. Are you open to exploring this opportunity?
Was this the origin of the "Berkeley Eats" file that was included in early versions of BSD Unix, and that had a list of Berkeley restaurants? I've been trying to track down a copy of it.
In IBM systems the problem was always fixed by replugging cards!!!! IBM always had connector problems(they put $10,000 to $20,000 worth of gold into 360's to try to solve the problem(gold plated connrctors), it did not solve the problem. In the PC they figured that screwing the cards down solved the connector problem!!!!
In another video they say they created a custom controler for the tape drives, that is what took them 3 years!!! Otherwise IF YOU HAVE ALL THE IBM MANUALS(BLUE BOOKS) WIRING DIAGRAMS. it should take no more than 1 to 3 days to install. It sounds like this was a card system that they reverse engineered to turn into a tape system
OJT VS COLLEGE TRAINED TECHS AND PROGRAMMERS I have been a college teacher, tech school teacher, on site teacher. OJT traing courses are 1 to 2 weeks = 4 years of college or 2 years of community college. THE BEST PROGRAMMERS AND TECH'S ARE OJT OR TECH SCHOOL(6 MONTH SCHOOLS) STUDENTS. THE WORSE ARE COLLEGE TRAINED STUDENTS. BECAUSE COLLEGE STUDENTS GET THE WRONG IDEA THAT THEY HAVE A WHOLE SEMESTER TO DO 3 PROGRAMS!!! THE BEST TECH I EVER HAD WAS MY MOTHER, WHO I TRAINED IN 3 HOURS TO READ I BM WIRING DIAGRAMS. THE WORSE 2 TECHS WERE A COLUMBIA UNIVERSITY PHD STUDENT(RECOMENDED TO ME BY THE CHAIRMAN OF COLUMBIAS ELECTRICAL ENGINEERING DEPT AND A US AIR FORCE VET TECHNICIAN. BOTH OF THEM WORKED ON AN IBM PRINTER($40,000 MACHINE WE WERE SELLING) FOR A WEEK AND DID NOTHING THEN QUIT!!!! WE LATER FOUND OUT THAT THEY STOLEN CHECKS FROM US AND WERE PASSING THEM AT LOCAL AP SUPERMARKETS. IT TOOK MY MOTHER(3 HOURS TRAINING) AND ME 2 HOURS TO TRACE THE WIRING AND FIX THE SHORT THEN SHIP OUT AND COMPLETE THE $40,000 DOLLAR SALE. BACK IN THE 1970'S, 1980, 1990'S I HAD A DATA PROCESSING SERVICE WITH IBM 360-40, 370-135 AND 3 SYSTEM 3'S. I DID ALL THE PROGRAMMING AND REPAIRS(I HAD BEEN A PARTNER IN A COMPUTER LEASING COMPANY) I ALWAYS NEEDED PROGRAMMING DONE. IN MY NAIVE DAYS, I HIRED COLLEGE STUDENTS(FROM BARD, COLUMBIA, HARVARD, COOPER UNION, COLLEGE OF STATEN ISLAND, MIT) TO DO FREE LANCE COMPUTER PROGRAMMING ON A PER PROGRAM BASIS. NONE OF THEM EVER COMPLETED A PROGRAM!!!! THEY WOULD COME IN PICKUP THE SPEC'S AND NEVER COME BACK. SO I SWITCHED TO P/T HIGH SCHOOL STUDENTS(SOME OF THEM WORKED FOR ME FOR 3 YEARS UNTILL THEY WENT OFF TO COLLEGE FOUND A FULL TIME PROGRAMMING JOB.(THEY, LIKE MY MOTHER COULD LISTEN!! AND TAKE INSTRUCTIONS. THE IVY LEAGUE BOYS(HARVARD, YALE, MIT, BARD) WERE NOT A TOTAL LOSS!!!!!(THAT SUMMER) I HAD A LARGE DATA ENTRY(KEY PUNCH) SERVICE, SO 5 OF THEM MADE GOOD KEYPUNCH OPERATORS.
"there is no overhead... in the common subset between C and C++" this bears repeating because it seems to be impossible to conquer the myth that C++ is a high overhead language.
The 1401 had a wild architecture. No adder. No multiplier. At least not in hardware. Instead there were addition and multiplication tables that you had to toggle into low memory. Even address calculation and indexing was done with table lookups. All serially-- one digit at a time! The engineers called it "CADET"-- meaning Can't Add, Doesn't Even Try. Pretty dang slow! What is now done in under a nanosecond took tens of microseconds. Some wise guy even wrote a FORTRAN compiler for the dang thing. The compiler was very unusual. It had like 69 passes. Each pass made some small transformation to the code. For example, there was one pass that deleted all the comment cards. Another pass that gathered up all the FORMAT statements. And so on. Not fast, but usually much faster than the punched-card equipment it replaced.
Estamos vivendo uma verdadeira Ditadura a sensura só tá servindo pras calar pessoas honestas hoje as pessoas honestas estão sendo perseguidas e calada por essa organização criminosa que começa daqui que estão atuando nos cargos públicos..
Aqui no Brasil a justiça Brasileira tinha que atuar pra ter uma eleição transparente, eles fazem vista grossa, enquanto muitos estão sofrendo como os presos políticos do dia 08 de janeiro e outros como Silvinei Vasques, Roberto gerferson, Sid, Daniel Silveira, e outros estão sofrendo a justiça Brasileira que podia ter atuado na intervenção estão compartuando sendo conivente com tudo de errado que está acontecendo no Brasil estamos vivendo uma ditadura tudo pra essa organização criminosa continuar no poder e continuar praticando seus crimes sem ter punição nenhuma.
Nessa última eleição pra Presidente veio dois homens de fora do país pra instruir a quadrilha no raque além de todos os rolos que eles cometem Derrepente não foi detectado mas teve participação interferência também do raque.
Your philosophy aligns with what the internet is. People have manipulated the idea of the internet into a vehicle for personal gain, but if it personally benefits someone else then they’re using the internet wrong, because it doesn’t align with a particular mission. That mission doesn’t involve every users life.
Woz was ahead of his time: "move fast and break things" could have described his activities sometimes. He didn't want to break things, but when you're a kid, you don't always know you're breaking things.
