This is a modified 2001-32N, a 40 column graphic PET with 9 inch screen.
It is running BASIC 2 (from the part numbers on the ROM's).
On the unmodified version, the space between the keyboard and the screen
is occupied with a black plastic part with the Commodore name and logo.
This part can be removed and underneath it are openings for 2 floppy
drives. This is the first time I have seen a floppy mounted there.
The back of the computer has been modofied also. The unmodified computer
has three slots at the bottom edge with card edge connectors sticking out.
Inside, the large circuit board at the right is the standard Commodore
circuit board for this machine. The card edge connectors at the rear have
adapters attached to them to provide different connectors on the outside.
All the other circuit boards have been added. The power supply at the left
rear is different, probably to make room for the added circuit boards.
The original power supply can be wired to run on 120 or 240 volts, so it
was not necessary to replace it for use in Europe.
From the dates on the chips, this computer was made in 1980.
