Here was my first experience....we had accounts with this units..

The IBM 2250 Display Unit

Then there was the 5080 engineering workstation....each tube require a 2 drawer file cabinet sized box at the display to hold all of the circuitry connected to a unit at the CPU via coax....

This goes with the photo above at #9:

***********************************************

The IBM 2250 Display Unit was originally shipped with the IBM 1130 computer, introduced in 1965. The 2250 could also be attached to IBM 360-series mainframes, as ours was to the 360/91. Like most IBM terminals, attachment was via control unit (or in this case, direct channel) rather than communication port.

The 2250 was the "first commercially available graphics terminal" if you don't count the DEC PDP-1 display (1961). As late as 1971 there were only about 1000 interactive CRT graphic terminals installed in the USA, compared with 100,000 line printers, 50-100,000 Teletypes, and 70,000 "alphanumeric terminals" (such as the 2260) (CACM Vol.14 No.1, January 1971, p.60).

Ernie. I am starting to feel old.... first computer I worked with while at tech school (Computer Technician 1 year program, back in 66), was a Philco 48 bit 1MHZ Transac 2000 Computer, the ones used at Sage Sites and elsewhere. I forget what model Teletype it was other then it was a 33 (110 baud rate).
Real high speed visual interface....heheh.

I interviewed with IBM in 1970. It was like a Warhol happening or Dylan's "Ballad of a Thin Man".

Regarding this line of the article excerpt above:

nor would you be fending off endless hordes of fast-moving zombies at high resolutions

one friend who passed through last year played this video game with friends and recorded them--much interunit shouting--quite interactive--

and, yes, he's been over in Iraq and will be returning, probably to Shariastan.

From my grandfather's grandfather's stereopticon, to my grandfather's punched cards to:

ATI Radeon R520

ATI had come a long way since the days of 3D Rage, and the biggest shift was yet to come. ATI's engineers had gone back to the drawing board, and what they came up with was the R520, a completely new architecture that was unlike anything that had been done before. Serving as the backbone for the new design was what ATI called an "Ultra-Threading Dispatch Processor." Like a foreman, the UTDP was responsible for telling its workers what to do, and when to do it. In this case, the 'workers' were four groups of four pixel shaders, 16 in all. This technique proved highly efficient and allowed ATI to get away with utilizing less pixel shaders than the 24 employed by the competition.

The R520 also had a redesigned memory controller. The new controller used a weighting system responsible for prioritizing which clients needed access to data the quickest.

Several other advancements had been made, most of which focused on efficiency. Image quality was better, full High Dynamic Range (HDR) lighting was implemented for the first time, and better DVD decoding were among the improvements that had been made.

The Seventh Century narcissist attempts to return us to the stone age savagery of Clark's "The Portable Phonograph"--

IBM said: Machines should work; men should think--

--but with Agent Hussein, men should not think, only work for the machine--

Let the irrepressible creativity exemplified in the GPU history prevail over the authoritarian psychopathy:
