Original Program by Jason Olds
Text and Modifications by J. T. Jones
NOTE: The top of BASIC is lowered to
56*256=14336 by the program. After
exiting from the program, restore the
top of BASIC to 40960 by typing, on an
otherwise blank line,
poke55,0:poke56,160:clr
and pressing the RETURN key.
On Issue #66 of LOADSTAR,
there is an entertaining card game by
Jason Olds in which you are pitted
against the computer. The
instructions for the game are
included in the program. The text
file by Fender Tucker that
accompanied the original program is
also on this disk.
Fender mentions that a beta-
tester had occasionally had trouble
with the (original) program "locking
up"; however, he points out that in
his playing the game, he had never
had this problem. The present author
similarly has never had the
(modified) program "crash" during the
many hands that he has played.
One should add, however, that in
the extremely unlikely situation
where the human player has eighteen
cards showing, that she has not been
able to play, on the very next play
by her, if she draws a card from the
stock, play is halted and the
computer wins the hand and possibly
the game.
If the object file (on this
disk), CRAZY EIGHTS, is disassembled,
one finds that the original author,
Jason Olds, had anticipated this
eventuality, although it is not
mentioned in the original text
material or program instructions.
Like so many of the early
LOADSTAR programs, the original
program can only be LOADed and RUN on
a disk drive having a device number
equal to 8. In those days, the vast
majority of US users had one disk, and
perhaps a casette recorder. With the
present modifications, the program
works with any disk drive having an
allowable device number; however, the
modified program has the drawback of
NOT returning to LOADSTAR, unless
device number 8 is used.
Of course, if necessary, before
LOADing and RUNning the original
program, one can always change the
device number to 8 by using a
suitable program or (for some disk
drives) by setting the dip switches
appropriately; however, I find it
advisable to provide for any
allowable device number to be used
and thus avoid the dreaded
"? device not present" error.

[NOTE:] So do we. Jeff and Fender
worked hard to get us into the 20th
Century. And a big thanks for Dr. Jack
for "Mod"ing these programs. As with
this program, We will inform you on
the Boot if Drive 8 is expected or if
the program does not return to
LOADSTAR.
