Infocom games consisted of two files: a platform-specific interpreter, and a platform-independent data file. By separating the platform-independent game data from the system-specific code, Infocom was able to quickly and efficiently develop games playable across the broad spectrum of competing platforms scattered across the late '70s and early '80s.
This is a collection of platform-specific .COM files for CP/M 2.2. Not a collection, really, by simply multiple copies of the single CP/M interpreter patched with the name of the game.DAT file to run, and with the terminal-specific cursor control codes for a dozen or so of the more popular terminal types of the early '80s -- from the LEAR SIEGLER ADM3 to the Vector, the Superbrain and more.
To be useful, you will need a copy of the .DAT file from any Infocom game prior to the Version 6 games Infocom began producing in the middle '80s (version 6 and later wouldn't run on resource-limited CP/M computers).
For example, grab a copy of ZORK1.DAT, make a copy of one of the .COM files in this collection configured for your terminal type, hexedit the .COM file, and patch the 8-byte string beginning at byte offset 5 with the string "ZORK1 " (that's padded with three spaces at the end). You're now ready to play Zork 1 on your CP/M machine.
All Infocom game .DAT files are available for download elsewhere at Vetusware.
