  1. This is where all the high school kids used to go after school. It seems like the decline of the mall coincided with a crackdown of kids hanging out there.

  2.  @Epic_C  Yeah, it was the response. I remember cruising around the mall was pretty popular. I never did either, but it seems like both events coincided. And I can't recall any riots, but I probably wouldn't know if they did happen

  3. I worked on vax's (as a user) all the way through college and for years after graduation. My friend's mom was an assembler (soldering) for DEC.

  4. When I was in grade school, my parent's used to give me $5 and drop me off in the morning and tell me where to be to get picked up in the afternoon. I guess things were safer then I remember trying to figure out how to buy tickets for the first time to see Smokey and the Bandit

  6.  @billmullins6833  I worked on a computer/detector where the programming was done by the length of wires and positioning of logic modules on the rack

  7.  @josephgaviota  Yeah, path signal is important, but the big thing MOSFET transistors are modeled as R-C circuits. Charging follows I(1-e^-t/RC)=v. The big thing is reducing the capacitance of the gate of the transistor. This is accomplished by making the gate smaller When v= ~1/ev_max, it's considered 'ON', or a logic 1, otherwise off. At the speed of the cray it probably was a factor, just like the size of motherboards became a factor when speed went to GHz range. Wires are also capacitors and must charge up before current flows. The smaller the wire, the less charging needs to be done

  8. I had a friend at NASA who according to him, was instrumental in getting cray off the ground. It was also central in starting global warming,

  9. I remember the seats, but I didn't think they were for actual sitting. I thought it was so neat and futuristic that they were liquid cooled. That was the ultimate in tech.

  10. I saw the first cray at the bradbury museum when I worked for a lab there. I think it was sitting in the corner and not even part of a real display, It was before the museum they have now and more of a warehouse.

  11. My roommate and friend's father was one of SGI's top salesmen. One day they had a show and tell expo at my univ and I got a bunch of swag. I was probably the only kid in the world with a giant 3D poster of HIV PR1 over my bed. I'm still blown away by one of their demos of water dropping into a bucket and you could change parameters in real time and spin the whole thing in 3 space. This was at a time before you could drag windows on a pc and rendering a 3d image could take hours

  12.  @josephgaviota  Yup.I was a digital engineer and material physicist for a few years and probably had an unhealthy obsession with cray in my childhood hhaha.

  13.  @mercster  I feel guilty sometimes of being in the right place at the right time for a charmed life. I just wish I'd realized it more at the time. I remember going with a friend since I didn't have a car and Bannana Rama's Cruel Summer was playing on the radio as we parked. Weird the stuff you remember

  14. Back before Algore was a person 🤣

  15. i @QuantumRift  It doesn't even do that. The logic gates are and, or and not. Addition and subtraction are created from these. Subtraction is really addition of a 2's complement number (a representation of negative number in binary).

  16. IIRC, about 700kilo flops and 32k ram. it does not take much

  17. I grew up fascinated by super computers. I got a tour once of my university's YMP-4. It was one of the coolest displays I've ever seen, a flat black room with the flaming pink cray alone in the center with flood lighting. In the corner was an SGI crimson terminal with 128MB(!) of ram.

  18. I looked at my university's entry into an Australian race in the early 90's. It didn't look interesting, so I didn't get involved, but I remember being told the motor cost $25k and had an efficiency of something like 97% or 99%. Ifft was an electric 4-wheel bicycle that carried it's own solar cells and had to charge a few hours in the morning before it could take off

  19. I got this lecture my first day of work from the president of the company. He said we could do it within 6 inches....but is that really what the customer needs (for the cost)?

  20.  @josephgaviota  haha. took me a minute. I'm slow...

  21. I was a little kid then, but was always fascinated by computers. I begged my parents to take me to computer conventions where they would just drop me off in front of convention centers. I remember looking at a Lisa in awe and seeing a color display for the first time showing a map of a city. About 30 years later, I bought a house and the realtor told me he worked as a salesman selling the lisa

  27.  @QuantumRift  IF-THEN is just a jmp instruction, i.e., load the instruction pointer based on a conditional bit in the cpu status register. Mathematical operations will set a status bit like overflow, negative, zero, etc. XOR'ing the value of two memory locations will set the zero flag if the values are equal. You then jmp to a location based on that flag.

  28. I used to work with and was friends an engineer who was a lead on this project. So many stories....

  31. I think most of the onboard motor cam video that we see from the Apollo program (separation with stage I booster falling away) comes from Apollo 6.

  32. A 1980's calculator had more computational power. It actually takes very little power to do most things dynamical. It just involves calculating F=ma, d=vt and a = v2-v1 about 20 times per second. times 6 (for 6 dimensions...x,y,z,yaw,roll,pitch)

  33. I remember when broadcasts went off the air for periods during the day and then again around midnight with the star spangled banner.

  38. I used to work with someone who was good friends with an engineer who worked on the Apollo reentry. We all used to all go to happy hour once a week and got lots of stories
