Lemonade Stand Ported to the Replica 1

I was thinking of some old BASIC games and my wife mentioned one she always liked: Lemonade Stand.  I looked for a port to the Apple 1 / Replica 1 but couldn't find one. There are lots of versions of it around, including some that run in a web browser.

After some digging around I found a version for the Mac that included the original Apple ][ version from 1979 as comments in it's source code. The comments in the BASIC code say that the original program was written by Bob Jamison of the Minnesota educational computing consortium and modified for the Apple ][ by Charlie Kellner in February 1979.

I extracted the original source code from the Mac version and removed anything to do with POKEs, graphics, etc. that was not supported on the Replica 1. After an hour or two I had it up and running.

It needs Applesoft Lite (not the Apple Integer BASIC built into the Replica 1) because it uses a lot of floating point calculations. I suppose it could be ported to the Integer BASIC with some effort. If you want to try it, the code is here.

Below is a transcript of a sample run of the game. It supports multiple players and let's you play until you quit or go bankrupt.
