The keyboard graphic responds to mouse clicks, touch events, and key presses.
Hold your shift key while clicking the PET keyboard to get the graphics
characters.
(The emulator simulates pressing the PET's left shift-key at the
same time as the clicked key.)
Changing the size of memory or changing the ROM version forces a reset of the PET.
The emulator has an IEEE-488 device at address 8. It can be used load and save (.prg) files.
Some programs don't run on ROM1 and some require more memory than the default 8K.
Game Notes
May include inaccurate AI generated content
This is a conversion to Commodore BASIC of a classic ZX81 game "Perilous Swamp" from Psion Software.
There are versions for the PET, VIC20 (+8K), C64, C16 and plus/4.
The standard PET version requires 16K or more, but there is also a version for the 8K PET which has had 2K saved from the program by removing space, combining lines and various other tricks. (the full fat PET version has been left in case you want to look through the code to cheat, which is obviously to be frowned upon)
Instructions from the ZX81 version:
"You are deep in the PERILOUS SWAMP, surrounded by dark reeds, deep stagnant pools and numerous pits and caves were strange creatures lurk. Your task is to rescue the princess, who has been captured by the evil wizard, and make it back alive to the edge of the swamp.
On your way, you must FIGHT, BRIBE or RUN from the fearsome monsters that confront you. If your combat strength is too low for a fight, you may have won enough treasure to bribe - otherwise you will just have to run.
You may also find powerful magic spells, but can you work out how to use them?
Only by conquering the mysteries of the PERILOUS SWAMP can you achieve the goal, and experience the unique pleasure of winning against the wizard and against your computer."
