Picture is of me operating the UNIVAC l in 1960 or 61.

Picture of me taken for a magazine at Remington Rand in Buffalo, NY. Picture is on my FB page. How do I get it to you? Ardis

Wasn''t the first computer built in 1936? I''m not sure

The first computer not commercial was the ENIAC

I''d just like to say, this computer was not the first to store programs and data in the same memory and I would argue not the first modern digital computer. The Small Scale Experimental Machine also known as Baby or The Manchester Mark 1 Prototype came online in 1948. This machine was the worlds first stored program computer and was built with the sole purpose of testing it''s cathode ray tube memory (also making this an earlier computer not to be built to replace a mechanical computer than the Whirlwind). The machine could hold 32 words of 32 bit length and had 7 instructions with subtraction but no addition. The machine had a typewriter for input, a cathode ray tube output, RAM, an accumulator and an accumulator so had all the major components of a modern computer. I help maintain a replica at the Museum of Science and Industry in Manchester in the UK. We''re currently carrying out repairs on the machine and an interesting offshoot of the current position is we have discovered we can run this valve machine which fills a room off of a regular household plug.

I think with commercial computer they mean that it was the first to be actually produced and marketed as a product that anyone could by (anyone who could afford it.) Remember that the Z4 was still a unique computer of which only one was built. The UNIVAC was the first one to go into actual serial production.

The Univac 1 was NOT the first commercial computer. The first commercial computer was the Zuse Z4 from 1950

has anyone ported linux to it?

About the question if vacuum tubes were hot... yes, a vacuum tube was like an light bulb, it had a filament that warmed up to 900 ║C (about 1650 Fahrenheit degrees), when the thing was powered it turned to bright orange. In this way, the electrons could go from the catode that was heated by this filament to an anode, by applying several hundreds of volts between them. By placing a grid between the anode and the catode, you could control the intensity of the current at the anode by varying the voltage of the grid.

In fact, the bulb of the vaccum tubes could get 50 or 60 ║C (about 120 to 140 Fahrenheit), less than the heat generated by a modern CPU, but if you add the heat produced by 5000 tubes, the technicians shouldn't take a cold easily.

(Sorry if my English is not very good, I have learned it by the public schools of Spain ;)

There actually is an emulator for this machine, and the Univac II. You can find it as shareware on SimTel, just visit www.simtel.net and search the Software Archive for "Univac" and you should be able to get it. It has been coded by one of the original Univac programmers!

I seriously think an emulator would work for this...

How about an emulator for this thing? I DON'T think I'd find one on the sales forums *ducks*, but I'd like to see this old beast in action, even if it's only on a Celery that weighs 2600 times less, and costed about 935 times less - with a printer.

Just think of a casemod on one of those things, though... you could throw a HUGE beowulf cluster in there on rackmounts. How quickly did the vactube array run? I mean, could you measure that in Hz, even? Also, how HOT did the thing get? Were vacuum tubes hot, or were they really cool? I mean, heat output of high-end desktop CPUs has gone up as the process size has gone down. E-mail me with the information - my e-mail is backwards for spam protection (I'll munge it less if I ever get around to setting up my spam filter again), and has a .NOSPAM on the end - remove the .NOSPAM, and then reverse it.
