who was the industrial designer? Cray-1 fits so well it looks straight out of 2001: A space Odyssey

somewhat related:

"Seymour said he thought it was odd that Apple bought a Cray to design Macs because he was using Macs to design Crays. He sent me his designs for the Cray 3 in MacDraw on a floppy.” reports KentK.

I wonder how many times faster my iPhone 17 Pro Max is? Sometimes I like to remind myself we are living in the future. A future that seemed like SciFi when I was a kid in the 70s! Sadly I don’t think we will ever see Warp Drives, Time Travel or World Peace. But we might get Jet Packs!

>how many times faster my iPhone 17 Pro Max is.. Sadly most of that power is not working for you, most of the time, but working against you, by spying, tracking and manipulating you. Bet that was not include in your sci-fi dreams in 70s..

I'd love to see you substantiate that - bet you can't.

I remember doing a report on this in high school in the late 80s. I'd love to do an order of magnitude comparison to a modern M4 Mac... Amazing how far we've come.

I just did a BOTE calculation for my iPhone (A17 Pro chip; GPU rated at 4 Tflops). According to the sales blurbage in TFA, the Cray 1 performed at 80 Mflops. (Yes, that is OBVIOUSLY not comparing apples to Apples -- pun intended). Unless I've dropped a decimal point, my iPhone is (capable of) 50,000 times the floating point speed of a Cray 1.

In my back pocket. To watch cat videos.

Cray-1 or Cray-2? IIRC Fluorinert was new with the Cray-2, while wikipedia suggests that the Cray-1 used a freon as coolant.

There you go. Not to doubt what you say, but we definitely had the love seat yet we also had a tank of vaguely flourescing green liquid. Maybe we had some intermediate state, the cray-1 cpu form but the cray-2 upgraded coolant. It wouldn't surprise me if we had the bastard love-child of leftovers from Boeing.

You consistency in spelling fluor as flour gave me visions of using pancake batter as a coolant :-D

Compare this to modern system: we could fully simulate this kind of slow computer in real time, I would guess, with all the wheels, clockwork and mechanics as well as logic circuits with full electricity. Deciding the simulation level would be a bit challenging - is this an atomic, an electron or more common sense simulation -; still I think the simulation would work as well as this kind of document.

> The aesthetics of the machine have not been neglected. The CPU is attractively housed in a cylindrical cabinet. The chassis are arranged two per each of the twelve wedge-shaped columns. At the base are the twelve power supplies. The power supply cabinets, which extend outward from the base are vinyl padded to provide seating for computer personnel.

It looks really nice - but never understood the seating. Who came up with that?

to deploy a 2nd hand Cray-1 at UQ, we had to raise the ex-IBM 3033 floor, it turned out the bend radius for flourinert was NOT the same as a water cooled machine. We also installed a voltage re-generator which is basically a huge spinning mass, you convert Australian volts to DC, spin the machine, and take off re-generated high frequency volts for the cray, as well as 110v on the right hz for boring stuff alongside.…

Cray-1 or Cray-2? IIRC Fluorinert was new with the Cray-2, while wikipedia suggests that the Cray-1 used a freon as coolant.

The GP also mentions X11 Terminals. My wiki-fu shows the X Windowing System came about on or around 1983, while Cray-1 was 1970s vintage. I assume that was an upgrade at some later point.
