Release 2 / Serial number AS000C

The Zork I Release 2 game file was extracted from a self-booting,
copy-protected TRS-80 Model I disk.  The disk itself was not an
original and did not come with a label or packaging, but it seems to
have been the early Personal Software release.  The game file is
clearly a legitimate, earlier version than Release 5, including some
bugs that were fixed in releases 5 and later.

Use the zpat (zcode-patch) utility and a copy of Zork I Release 88 to
reconstruct zork1_2.dat from zork1_88_to_2.pat.
