Remember writing your programs in BASIC? Remember computers with no monitors, phone couplers, huge CPUs, output printed on rolls of manila paper looking stuff?
If you are into old board games, or better yet, old computers, this game is all kinds of cool!! It is called Input/Output Game and was produced by Educational Insights, No. 3155. (They still make many nice educational games.) I do not know the date, but it reminds me of my first computer course in the late 1970s. It features the input terminal/keyboard, a large CPU and the printed output. The game is based on BASIC computer language.
In it you must collect Line Cards enough to complete a program. There are yellow STATEMENT cards, with words like input, let, rem, print and orange COMMAND cards with words like end, new, and load. Then there is a 3rd set of cards, the line cards, with rem, end, let, input, etc. across the top and programs, or partial programs written on them.
The instructions include the standard game and supplemental activities. In the instructions it states: "The Following Is Not For The Faint Of Heart, Anyone easily frighted by technical jargon should turn back now!" just before the Supplemental Activities section. These supplemental activities are actually teaching tools, and can be run on your TRS-80.
You do have a TRS-80 don't you?
