I’m so old that

I remember when we were all going to switch to the metric system, ANY day now. I-19, heading south from Tucson to Mexico, was a test highway measured out in kilometers instead of miles. It was going to be the vanguard of all highways being measured that way. And I remember the American public going, "Meh. No thanks". I-19 is still measured that way, but all the other highways are still miles.

And they started putting up the signs with miles and kilometers. Everyone going........ummm......we aren't Europe.

I'm so old I remember when doctors made house calls.

I remember when the Orlando airport was an old hanger with about 50 parking spaces out front.

I remember coming back to school from the Christmas break and the teacher changing the calendar and saying this is no longer 1954, it is now 1955.
 
I'm so old I remember floppy disks and dial up modems.

EEK!

My first modem was a homemade contraption, that I interfaced to my Apple ][ via the joystick port. I wrote a terminal program in 6502 assembly language, that polled the relevant input watching for a start bit, and then cycled through a loop that was crafted to take exactly 1⁄300 of a second per cycle, to read in the subsequent bits at 300 baud.

A similar routine sent output in a similar manner, manipulating at output bit via a 1⁄300 loop.

I had another output control the hook switch, so that I could dial the phone in a pulse-dialing manner.
