Computers through history
Design on the Harvard Mark 11 computer project began in 1944 at Harvard University and was completed in 1947.

It used relay logic and had simple programing abilities

Computers are a bit more advanced these days.

The first lunar lander had a "computer" called the Apollo Guidance Computer --- It contained a massive 2032 words of memory (2032 x 16 = 32,768 bits of RAM memory.). One must wonder how they did it with such a limited computer, huh?

Historical "update"... :)
When I was a member of another club I remember Brig posting gameknot.com one of her NASA pics apod.nasa.gov about the first computer ...

Who here owned a commodore 64?

The original definition of a "computer" was a person who could do arithmetic quickly and accurately using pen and paper.

Nope
but I did own an apple 11 during the late 70's that I dropped almost 3 grand on --- the thing was "loaded" with 8 K of ram and I believe the CPU clicked along at about 1-meg. You could load a plastic encased tape drive into it for amazingly slow games and it also had Basic for the programmable language. I don't know how fast the CPU bus board was, but I'm sure that it was at-least as fast as a turtle.
The Apple 11 was, at the time, being touted as more capable of a computer than a home owner would ever need.

I earlier owned a small hand-held computer by Tandy (TRS 80) that was interesting, but quite limited in it's abilities. I believe that I paid about $500.00 for it.

And Colin: There's no doubt that a brain is a highly capable, majestically loaded, analogue plus digital computer when it's used correctly.

Apple was the gold standard. I remember seeing Thier game Castle Wolfenstein. And was blown away lol.

I had a Star trek game for the Apple 11 where one person had a Klingon ship and the other had the Enterprise.

You could program the ships to launch photon torpedoes and phasers, etc, and maneuver your ships into position or to get away --- The Klingons had cloaking, but they couldn't launch during cloak. Warp speed was also available, but it was near useless against the Klingon weapons because of the "slow" acceleration of the Enterprise and the stealthiness of the bad-ass Klingons.

Each launch action required three or more "moves" and each move needed a couple minutes to complete --- My opinion was that the Klingon was a better, safer steed to mount for the battle, but that's just my opinion.

Anyone ever play this? It’s completely web based now.

Apple II
My first PC was an Apple IIe, though I did a lot of programming on the II.

The 6502 CPU clock speed ranged from 1 to 3 MHz. The earlier, more common version was 1.

I bought mine for $800, and sold it not long after for $500 to get my hands on an 8088 IBM PC XT. I don’t know whatever happened to that box, but I rewrote much of my Apple BASIC software into MS DOS BASIC, later GW BASIC. That CPU was 4.77 MHz, with a later box switchable between that and 10.

More relay logic
This isn't a computer, but I own a 1956 United Arcade puck bowling that was the first true scoring bowling machine --- the thing is stuffed with about 60 high quality, probably 30 amp standard relays that were custom designed for the machine and vary from 2-pole-two throw type to 4-throw 2-pole, as well as well as about 8-rotary relays that have up to 15-poles and up to 30-positions that are used for memory. up to 6-players can play at a time. It weighs about 500 pounds and sounds lime a bunch of fire crackers when the relays start energizing
I bought it from a guy who didn't know how to fix it, because it was the most complex relay logic circuit I had ever seen and was assembled by a craftsman.

The thing came with a 24" x 36" schematic with an engineering revision that apparently did something for the true scoring. I was able to repair it all the way to the 10th frame extra ball (can't make a 300 score), but I then dumped the repair due to boredom with the project.
It now has a few dimes stuck n the coin unit --- I played 20 or so games on it, but haven't touched is for about 12 years other than to jockey it around the basement game room a bit --- I also have a foos ball table and a bumper pool table down there that I use occasionallly (both are for sale)
Foosball table
www.pooltables.com
Bumper pool table
www.legacybilliards.com

It's also for sale if anybody's interested, and I'll even try to fix the tenth frame if you give me enough money for it. 
This is the ball version of the bowling machine --- It the same size and looks looks the same except that mine uses a puck instead of a wood ball.
