Well, here goes ... again! I tried to make this post using my iPad and everything got wiped out. Obviously user error, I will learn eventually. Computers and I go back a ways. Not as much as some but more than most. My first encounter with computer circuitry was about 1965 or 1966 when I was in training to repair specific circuitry which included some new fangled logic circuits. My first experience with actual computers came in 1974, my second semester in college, when I took a required Programming In FORTRAN IV course. I've been addicted ever since. My first computer was an Apple ][ with 48 KB RAM and dual 140 KB single-sided 5 1/4" floppy drives. I used to keep an OS disk in drive 1 and data disk in drive 2. I recently gave it away but still have my Apple ][e with 768 KB RAM and a 20 MB hard drive easily at least 10 times the size of my new iPad2. I also have various WinTel machines because I got out of Apples and into PCs because that is where people needed help. I've finally had enough and have decided to try to relearn the Apple way. I also still have an original 512 KB Mac and harassed the tech at the Apple store by bringing it in so he could transfer all my software from it to my new Mac. Needless to say, I was told by the (other) techs that they loved the joke. I think what really clued him in was that I also took in a mag tape and some punch cards for the data transfer. Ah well, enough for history. From the above, you should be able to tell I enjoy jokes but I enjoy puns even more. When teaching, I used to PUNish my students unmercifully. Most of them survived. If you want to learn anything else, you will have to ask but I won't guarantee an answer.
