SYZYGY v0.1 for HP48SX using CHIP48
One of the first games I remember playing on a computer was
called "syzygy" on a now ancient TRSH80 Model 1. It has since
appeared on other computers under various names. Why it was
called syzygy, I have no idea (consult Websters). However, since
the HP48SX has approximately the same memory, graphics and cpu
power as my TRSH80 did (something like 16kB, 128x64, and a 1.2Mhz Z80),
I thought it would be amusing to play it again. Now, approximately
to my recollection, and with many apologies to the original author,
here is a CHIP48 version of SYZYGY for the HP48. Enough drivel.
The object of the game is to seek out "targets". You do this with
your syzygy. Initially small, the syzygy will grow by some amount
each time a target is hit. Eventually, your syzygy will
be so long as to make tougher and tougher to get any points (and easier
and easier to get killed). Confused? Just try it.
Anyways, the syzygy is not allowed to run into anything except targets.
It cannot run into the screen border (if present), or itself (this
includes backing into itself). Fast and immediate death will result.
Don't worry if you die quickly a few times. The keys take a few
minutes to get used to.
To start: + start/restart game with border
- start/restart borderless game
To play: 9 up
6 down
1 left
2 right
After death: SPC display score, etc, then + or - to start
Chip48: <- chip48 exit (backspace key)
+/- chip48 toggle sound
ENTER chip48 restart game from beginning
Standard chip48 program procedure: clip out the following string and
download to your hp48. Convert to a binary string with ASC->. Store
the new string into the variable "SYZYGY". Recall the variable to
the stack. Execute the code object "CHIP" on it. Play.

Alternately, I have also enclosed the uuencoded binary object, to give
everyone a second chance at getting this downloaded: uudecode the below
stuff. Download directly to HP48 using "binary" transfer on both sides.
Recall the variable to the stack, etc. as above.

Good luck! (I realize the program is rather huge, but consider
the price. :-) The program works fine on my REV-D hp48sx under
CHIP-48 v2.25. Source code may be posted if demand warrants.
