OK, sooo, what is Retro Challenge? See here.

This will be my first attempt at RC, so we'll see what it brings. I intend to write a fuel consumption calculating program on an HP-200LX using Borland Turbo Pascal 5.5 which I purchased as a student around 1990. I found the manuals and disks in a box during a recent move and managed to install it on the 200LX. The 200LX has an Intel 80186 CPU and the operating system is MS-DOS 5.

So, now on to see if they'll accept my entry ....
