I synthesized nine Wikipedia articles into a new article dedicated to BASIC interpreters: A BASIC interpreter enables users to enter and run BASIC programs and was, for the first part of the microcomputer era, the default application that computers would launch. Users were expected to use the BASIC interpreter to enter in programs (often from printed listings) or to load programs from storage (often cassette tapes). Why do I think a new article is warranted, rather than just referring to the BASIC and Interpreter articles? As I write in the article: BASIC interpreters are of […]

Back in 1980, I created a computer game for my TRS-80 Pocket Computer, inspired by Tunnels & Trolls. Given the passing of Rick Loomis, I thought I would dig it out. As with T&T, I had attributes: ST (Strength), DX (Dexterity), and CN (Constitution, used for hit points). But I skipped LK (Luck) and CH (Charisma), and I used D&D’s WS (Wisdom) instead of T&T’s IQ (Intelligence). Like T&T, and unlike D&D, attributes could increase: in my case, quickly, after every monster, rolling three dice and if the total exceeds […]

As we discussed last time, while BASIC Computer Games became a bestseller because of microcomputers, the games themselves dated back to timesharing systems using teletypewriters. As a result, a few of this first generation of BASIC games produced printed output as the primary purpose or as the game itself. The most game-like of these was Amazing, which would generate a new, random maze that you could solve on the printout.

When I first met Rick Dakan, one of the creators of City of Heroes, we talked about a class he’s teaching at Ringling College of Art and Design in the spring, “The History of Game Art.” The class starts with Spacewar! in 1962 but to my surprise doesn’t cover some of the BASIC games of the timeshare era (circa 1964 to 1976). Yes, some have “art” (in fact, some are only art). BASIC Computer Games, the first computer book to sell a million copies, is thought of as a collection […]

I was surprised that there was no easy way to play David Ahl’s classic book, BASIC Computer Games, in your browser. You can now play them here: Play BASIC Computer Games in Your Browser BASIC Computer Games sold over a million copies as microcomputer users in the 1970s and early 1980s typed its programs into their Commodore PETs, Apple IIs, and TRS-80s (among many other machines). I smashed up Ahl’s listings with Joshua Bell’s Applesoft BASIC emulator to make it easy for you to select any of these programs and […]

What was included and what wasn’t in the very first version of BASIC might surprise you. First of all, Dartmouth was waiting for the time-sharing system equipment from GE to arrive, but in the meantime Kemeny and Kurtz decided to write a compiler for BASIC, to have it ready when implementation of the time-sharing system began. While the duo had designed BASIC to be an interactive language, with the goal of removing students from the tyranny of interacting with computers through batch processing of punch cards, the two still envisioned […]

In the fall of 1975, the People’s Computer Company (PCC) poured more energy into their “Build Your Own BASIC” project, fired up by the announcement of Altair 4K BASIC by MicroSoft [as it was then] for $150. They wanted to create an implementation that was free for anyone to use. With microcomputers and microprocessors proliferating, they envisioned a virtual machine that could be ported from platform to platform: When you write a program in TINY BASIC there is an abstract machine which is necessary to execute it. If you had […]

Growing up, I remember going to friends’ houses and typing in BASIC programs. We’d take turns entering the listing and double checking it, then play whatever game it was. Back then, everyone had a different microcomputer. I had a TRS-80 Model I, the library had an Apple II (too expensive for most of us back then), Ron had a VIC-20, Mark had a TI-99/4A, Mike had a Commodore 64, Chris an Amiga, and so on. Even the Bally Astrocade had a BASIC cartridge. The iOS app LowRes Coder returns us […]

Update: Advent 101: Streamlined, Randomized Colossal Cave Adventure When my 11-year old wanted to learn to program last spring, I got him a book on writing games in JavaScript. It had the source code for four games, but my son found it difficult. Four games?! A far cry from the 101 BASIC Computer Games that was my go-to (ahem) when I was his age, programming a TRS-80 Model I. So I looked at a number of different BASIC implementations for his iPod Touch, eventually landing on LowRes Coder, which turns an […]

BRAINTREE, Mass.–(BUSINESS WIRE)–April 1, 1998–Perseus today announced the immediate availability of a new version of Perseus SurveySolutions written specifically for the Tandy/Radio Shack TRS-80 Model I. “When we realized that no new software had been developed for the TRS-80 Model I in at least a decade, we felt compelled to re-open the market window,” said Richard Nadler, President of Perseus Development Corp. “The TRS-80 is an exciting platform for us, given its installed base. While some software companies were started in the garage, we’re the first to develop software for […]
