Hello,
My name is George, but many call me kasmar45. I am 78 years old and long retired. I have worked in the IT business for 50 years. I started out wiring and operating tab equipment. IE (403, 407, 604, sorter, etc, etc. Then I got a job operating a 305 Ramac. That was fun. My next job I operated a 1401 computer. It had 4k of usable memory. How could you write a program with only 4k of memory you might ask. Well back in those days code was written in line, started at the top and finished at the bottom. Our devs programmed in assembler. When a program was started it read the first 4k into memory from the ram file, and when it came to the end of that it it read in the next 4k, etc, etc. Thats a simplfied explanation. I ended up my career doing app support at pick systems. I code today as a hobby.
