51 ** C version by Eric P. Allman 5/76 (U.C. Berkeley) with help
52 ** from Jeff Poskanzer and Pete Rubinstein.
54 ** I also want to thank everyone here at Berkeley who
55 ** where crazy enough to play the undebugged game. I want to
56 ** particularly thank Nick Whyte, who made considerable
57 ** suggestions regarding the content of the game. Why, I'll
58 ** never forget the time he suggested the name for the
61 ** Please send comments, questions, and suggestions about this
65 ** Electronics Research Laboratory
67 ** University of California
68 ** Berkeley, California 94720
70 ** If you make ANY changes in the game, I sure would like to
71 ** know about them. It is sort of an ongoing project for me,
72 ** and I very much want to put in any bug fixes and improvements
73 ** that you might come up with.
75 ** FORTRASH version by Kay R. Fisher (DEC) "and countless others".
76 ** That was adapted from the "original BASIC program" (ha!) by
77 ** Mike Mayfield (Centerline Engineering).
79 ** Additional inspiration taken from FORTRAN version by
80 ** David Matuszek and Paul Reynolds which runs on the CDC
81 ** 7600 at Lawrence Berkeley Lab, maintained there by
82 ** Andy Davidson. This version is also available at LLL
83 ** and at LMSC. In all fairness, this version was the
84 ** major inspiration for this version of the game (trans-
85 ** lation: I ripped off a whole lot of code).
87 ** Minor other input from the "Battelle Version 7A" by Joe Miller
88 ** (Graphics Systems Group, Battelle-Columbus Labs) and
89 ** Ross Pavlac (Systems Programmer, Battelle Memorial
90 ** Institute). That version was written in December '74
91 ** and extensively modified June '75. It was adapted
92 ** from the FTN version by Ron Williams of CDC Sunnyvale,
93 ** which was adapted from the Basic version distributed
94 ** by DEC. It also had "neat stuff swiped" from T. T.
95 ** Terry and Jim Korp (University of Texas), Hicks (Penn
96 ** U.), and Rick Maus (Georgia Tech). Unfortunately, it
97 ** was not as readable as it could have been and so the
98 ** translation effort was severely hampered. None the
99 ** less, I got the idea of inhabited starsystems from this

109 ** NOTES TO THE MAINTAINER:
111 ** There is a compilation option xTRACE which must be set for any
112 ** trace information to be generated. It is probably defined in
113 ** the version that you get. It can be removed, however, if you
114 ** have trouble finding room in core.
116 ** Many things in trek are not as clear as they might be, but are
117 ** done to reduce space. I compile with the -f and -O flags. I
118 ** am constrained to running with non-separated I/D space, since
119 ** we don't have doubleing point hardware here; even if we did, I
120 ** would like trek to be available to the large number of people
121 ** who either have an 11/40 or do not have FP hardware. I also
122 ** found it desirable to make the code run reentrant, so this
123 ** added even more space constraints.
125 ** I use the portable C library to do my I/O. This is done be-
126 ** cause I wanted the game easily transportable to other C
127 ** implementations, and because I was too lazy to do the doubleing
128 ** point input myself. Little did I know. The portable C library
129 ** released by Bell Labs has more bugs than you would believe, so
130 ** I ended up rewriting the whole blessed thing. Trek excercises
131 ** many of the bugs in it, as well as bugs in some of the section
132 ** III UNIX routines. We have fixed them here. One main problem
133 ** was a bug in alloc() that caused it to always ask for a large
134 ** hunk of memory, which worked fine unless you were almost out,
135 ** which I inevitably was. If you want the code for all of this
136 ** stuff, it is also available through me.
