First one was a Radio Shack PC2 - basically a programmable (basic) calculator. Mostly for hobbiests. My first real computer was a PC with 8k ram and two 5 1/4" floppy drives (A & B). I never did use the TRS 80 8" floppy drives. Then a few months later, I moved up to 16k ram, with a 5MB hard drive, and then to a 64 k ram and a 10Mb hard drive. I thought that was all the computing power I would ever need. I started using the old VisiCalc spreadsheet program in about 1980, which led to Lotus 1-2-3 (which I still use today), and then to Excel. Since I started my career in finance and accounting in the late 1960's, well before there were any desktop computers, I can fully appreciate the exponential productivity gains the computer has allowed.
