8.5 Commodore PET/CBM 20XX series (build-in tape drive)
Commodore made a name in the computer industry with the iconic PET computer. With it's
adorable (but not so practical) keyboard and the build-in tape recorder this machine made low cost
computing possible and started a revolution in the industry. Commodore made this model in
different memory configurations (8, 16, 32K). Despite from memory differences, these models all
work the same and are therefore referred to as the 20XX series in this manual. The 20XX series are
well known for their build in cassette player (cassetteport#1) but it has also a cassetteport #2.
Cassetteport#1 is located inside the case and directly connected to the build-in tape drive. Therefore
it is not as easily accessible as cassetteport#2, which is conveniently located at the back of the
computer. The Cassiopei could function on both cassetteports, but the speedloader software inside
the Cassiopei must know to which port it is connected. Therefor the correct port must be chosen in
the computer model settings of the Cassiopei settings menu. The computermodel setting for the
model as shown in the picture below would be “50Hz PET20XX #2” because the Cassiopei
connects to the cassetteport at the rear, which is cassetteport #2.
This model requires 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 cassetteport connector, then replace the
back cover.
Usage:
Configure the Cassiopei to be used on a PET/CBM 20XX (build-in tape drive) 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.
LOAD””,2
<return> (BASIC 1, startup screen shows *** COMMODORE BASIC ***)
LOAD””,2 <return> (BASIC 2, startup screen shows ### COMMODORE BASIC ###)
LOAD””,2 <return> (BASIC 4, startup screen shows *** COMMODORE BASIC 4.0 ***)
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:
If the cassiopei was to be connected to cassetteport #1 then replace '2' by '1' in the examples above.
Or simply type LOAD<return>
