Commodore CASSIOPEI, Руководство пользователя

Страница: 46 / 76

Usage:
Configure the Cassiopei to be used on a PET/CBM 20XX & 30XX computer, this is required in
order to define all timings of the Cassiopei for this type of computer, see the chapter “Configuring
the Cassiopei”. Do not attempt to use the Cassiopei while it is not configured.
The Cassiopei's requires the following sequence of commands independent of it's operating mode.
Be aware that there are differences between the various versions of Commodore BASIC.
<not supported> (BASIC 1, startup screen shows *** COMMODORE BASIC ***)
Shift + RUNSTOP (BASIC 2, startup screen shows ### COMMODORE BASIC ###)
<see note> (BASIC 4, startup screen shows *** COMMODORE BASIC 4.0 ***)
Note: Please note that a 30XX with BASIC 4, functions like a 40XX, so in this case please
configure the Cassiopei for use with a 40XX and use the 40XX menu program.
The computer will now ask you to “press play on tape”:
–
press the PLAY button on the Cassiopei to load the currently selected game/program
–
press the MENU button in order to load the menu program to define your new settings.
–
depending on method of loading type RUN to start the loaded program
Note:
When a program is loaded using the Cassiopei's fastloader, the program is executed directly after it
has finished loading. However . TAP files do no use the Cassiopei's fastloader and depending on
the .TAP file itself it may be required to type in RUN.
Some programs cannot be loaded using the Cassiopei fastloader. For instance the game “Wasps”
which loads to memory locations $027A - $1400, this is a problem because these locations are also
used by the fastloader routines of the Cassiopei. As it uses tape buffer#1 (which starts at $027A).
However it is still possible to load this game using the Cassiopei, but it requires the kernal loader.
By loading the game using the standard kernal loader (also known as the slowest method of
loading) the game is as it was designed.
In some occasions when the RUN command is entered, the Cassiopei loads the program, but the
computer responds with an error message. Most of the times entering the RUN command again will
start the loaded program without any problems. In those occasions it would have been better to use
a SYS command to start the fastloader routines. So instead of RUN, type SYS 1040 (Also shown
when typed list after loading of the fastloader program).
