My very first computer was a TSR-80. I learned to first code out of necessity – you had to type in all the programs you wanted to play. My dad then purchased one of these wonderful beauties: The IBM PC 5140 Convertible.

The computer was a miniaturized IBM XT 8088 system with only 2 floppy drives and no hard drive. Still, it was a huge step up with the ability to save and load programs from floppy disks.

I love that people try to preserve the history of these wonderful old machines – and you can find everything about the system including original boot disks, specs, and configurations. There also appear to be copies of the original boot disk and ROM set that work on MAME.
