As the image above demonstrates, the PET/CBM 8000 series require the use of an additional stand.
You can attach this by removing the back cover of the Cassiopei and then slide the stand gently
over the cassiopei's cassette port connector, then replace the back cover.
Usage:
Configure the Cassiopei to be used on a PET/CBM 80XX 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 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.
BASIC 1: startup screen shows *** COMMODORE BASIC ***
BASIC 2: startup screen shows ### COMMODORE BASIC ###
Basic version 1 and 2 were never released for the 80XX series, if your computer uses these
versions, the system has been downgraded. This practice is not supported by the Cassiopei. I would
kindly advise to restore the computer to it's original state. So that it can function as intended by the
nice people of Commodore.
The proper BASIC version for the model PET/CBM 80XX computer is BASIC 4
(BASIC4: startup screen shows ***
COMMODORE BASIC 4.0 ***
) and this is how you should use it
in combination with the Cassiopei.
When the Cassiopei is connected to cassetteport #1, type:
LOAD
<return>
When the Cassiopei is connected to cassetteport #2, type:
LOAD””,2
<return>
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.
–
when done loading, type RUN to start the loaded program
Note:
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.
Which is way slower and therefore not the preferred method of loading. But by loading the game
using the standard kernal loader the game loaded 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. In many occasions 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).
