Let's go back down "Memory Lane' for just a few minutes.

Fortunately (despite being in the middle of the "Flower Power" era!!), I can remember way back to the late 60's (or was it - the very early 70's....if you get my 'Drift' here........!), seeing my first computer. It and the required environment, took up nearly a whole floor of a building! A similar model of the computer itself can be seen here at:- www.punch-card.co.uk/360.htm
All work was ushered into a room where 4 lasses sat behind these 'Punch Card' machines. 2 would enter the data onto the cards and the other 2 would verify the accuracy of the info recorded.
Once all the data was "batched" (I think it was called), it then went into the Computer Room itself (a glass, enclosed area taking up approx half the floor of the building) which was a hallowed area. No smoking anywhere near it! The room was kept at a constant temperature. I think from memory, there was a Paper Tape reader, 4 Magnetic Tape drives/readers, a chain printer, Punch Card input/reader, CPU and operator's console. No Disks were used, everything was backed up, or stored on Punch Cards or Magnetic Tapes, so you can imagine how much space was required, just for that alone!
Any large undertakings were started by the night shift, as sometimes it would take hours just to sort data for 1 job! (remembering that data was shuffled to and fro between the Tape units and CPU until a final sorted tape was produced).
Today, you would be sitting in front of your Mac/PC, or whatever, and look at how much space it takes up and how quickly you can get things done. I simply can not remember the speed of the IBM 360/2300, but the link page:- www.punch-card.co.uk/360.htm will tell you that, however, the point I am making here is technology (particularly that of the "Garage" type) and how quickly things can change! thanks to the likes of Jobs/Wozniak & ......dear I say the names in this forum....... Gates/Allen.
After seeing of all of this, I went out and ultimately bought a Mac!
