What does JRT mean?

JRT is an implementation of the Pascal programming language. It was available in the early 1980s on the CP/M operating system. At the end of the 1970s, the most popular Pascal implementation for microcomputers was UCSD Pascal, which many people considered overpriced at hundreds of dollars. The original basis for UCSD Pascal was the p-machine compiler from ETH Zurich the originators of Pascal. JRT was a Pascal interpreter, that compiled down to its own pseudo-code totally separate from UCSD Pascal p-code. It was written by Jim Russell Tyson who had the idea that if he dropped the price he'd sell more copies. He sold it cheaply, reducing the price from $295.00 to $29.95, and it was a wild success. Too wild as it turned out. Orders far surpassed JRT's ability to produce product and the company eventually filed for bankruptcy in November 1983 with many cancelled orders and unable to meet the still high demand. The product eventually continued through a version 4 priced at $69.95 and along with a Modula-2 at $99.95 may have been successful had not Turbo Pascal shown up for about the same price. Turbo Pascal was a true compiler with an IDE as well as a business model that allowed it to meet customer demand.
