Our first "IBM PC" was a PC/XT turbo clone from a local mom-n-pop shop (prior to that we had an Apple //e with only a monochrome monitor and a floppy drive).
4.77/8 MHz, 20 MB hard drive, CGA monitor, MS-DOS 3.something.
Boy, was I in awe ... it opened up a whole new world for me! Color! Subdirectories! Function keys! Bulletin boards! Structured QuickBASIC programming!
