Originally published by Mad Hatter Software for the TRS-80; the 1979 catalogue shows it was also available for 16K Apple II and Exidy Sorcerer.
Later included in the Captain 80 Book of Basic Adventures with the title Entry into King Tut's Tomb in the game listing itself.
Seems to have been ported to C64 and released (often on compilations), possibly multiple times by different companies. One version (listed under the publisher Comp-U-Soft) is credited as being adapated by David Conley. Whether the C64 ports were authorised is currently unknown.
Jim Gerrie has created a version of the game for the TRS-80 MC-10.
