Had to load a short program to read paper tape using switches on the console. If you were lucky the core memory would still contain the program when switched on, otherwise you had to reenter all of the steps. Load binary loader program from paper tape. Then load Focal a programming language similar to Basic. Then write my stock market game in Focal using a teletype console. I still have a printout of the source code for the game. I was hooked and still am all these years later.

Its going to get a lot of traction in the Philippines as my IP (assigned by a major local telco) is banned from the site
