Question: Cortex System was developed for the role playing game released in what year?
Context: Beneath Apple Manor is an early roguelike game released by Don Worth for microcomputers, which had a Lo-Res Apple release in 1978 (through The Software Factory) and high-res multi-platform releases in 1982 and 1983 (through Quality Software).  The goal is to obtain a Golden Apple on the bottom floor of the dungeon.  There are 10 rooms per level in the low-res version, and 5 in the high-res version.  The high-res versions may be played in low-res/text mode, thereby gaining this increase in level size.  It is notable for being the first commercial role playing game developed and released for a home computer as opposed to a mainframe computer.

To date MerpCon has been held each year in Spokane, WA, USA.  Beginning in 2009 MerpCon began to transition to being called Tolkienmoot as this convention's venue began to expand to include more Tolkien-related activities, events, and guests beyond just role playing in Middle-earth.
