8.6 Commodore PET/CBM 20XX and 30XX series
Commodore has build many variations of the PET 2000 series. Not only did they vary the amount
of RAM, they also removed the build-in tape drive. Which is a bit of an issue because the cassette
port numbers are different between the different model of the same series. However this is quickly
noticed. Because the build-in tape drive is always #1 and the external tape drive is #2, if there is no
build-in tape drive then the external tape drive is called #1. The Cassiopei fastloader software needs
to know where the tape drive is located (#1 or #2) therefore the proper computermodel must be
chosen in the settings screen.
Soon after the release of the 2000 series Commodore came with the 3000 series, which is very
similar to the 2000 series that have no build-in tape drive. In fact they are so similar that the
Cassiopei can use the same fastloader routines for both series of machines. Regarding the 3000
series, Commodore made this model also in different memory configurations (3008, 3016, 3032).
Despite from memory differences, these models all work the same and are therefore referred to as
the 30XX series in this manual.
As the image above demonstrates, the PET/CBM 2000 and 3000 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 cassetteport connector, then replace the back cover.
