not uncommon for small companies and municipalities to write custom programs for computers such as the TRS-80 to process a variety of data. In one case a small town's vehicle fleet was managed from a single TRS-80. By 1985, the company's Ed Juge stated that other than Scripsit and DeskMate, "we intend to rely mostly on 'big-name', market proven software from leading software firms". A full suite of office applications became available from the company and others, including the VisiCalc and Multiplan spreadsheets and the Lazy Writer, Electric Pencil, and from Radio Shack itself the Scripsit and SuperScripsit word processors. Compared to the contemporary Commodore and Apple micros, the TRS-80's block graphics and crude sound were widely considered limited. The faster speed available to the game programmer, not having to processor color data in high resolution, went a long way to compensating for this. TRS-80 arcade games tended to be faster with effects that emphasized motion. This perceived disadvantage did not deter independent software companies such as Big Five Software from producing unlicensed versions of arcade games like Namco's Galaxian, Atari's Asteroids, Taito's Lunar Rescue, Williams's Make Trax, and Exidy's Targ and Venture. Sega's Frogger and Zaxxon were ported to the computer and marketed by Radio Shack. Namco/Midway's Pac-Man was cloned by Philip Oliver and distributed by Cornsoft Group as Scarfman. Atari's Battlezone was cloned for the Models I/III by Wayne Westmoreland and Terry Gilman and published by Adventure International as Armored Patrol. They also cloned Eliminator (based on Defender) and Donkey Kong; the latter wasn't published until after the TRS-80 was discontinued, because Nintendo refused to license the game. Some games originally written for other computers were ported to the TRS-80. Microchess has three levels of play and can run in the 4 KB of memory that is standard with the Model I; the classic ELIZA is another TRS-80 port. Both were offered by Radio Shack. Apple Panic, itself a clone of Universal's Space Panic, was written for the TRS-80 by Yves Lempereur and published by Funsoft. Epyxs Temple of Apshai runs slowly on the TRS-80. Infocom ported its series of interactive text-based adventure games to the Models I/III; the first, Zork I, was marketed by Radio Shack. Adventure International's text adventures began on the TRS-80, as did Sea Dragon by Westmoreland and Gilman, later ported to the other home micros. Android Nim by Leo Christopherson was rewritten for
