Commodore VIC-20 - Page 13

Introduction xl
The 1525 printer is essentially an upgrade of the 1515 printer. It
operates like the 1515 and interfaces to the VIC in the same way. The major
differences are its slightly improved operation resulting from new internal
software and its redesigned case
that allows it to accept standard 9-inch
(including perforations) paper.
The
1541 disk drive was introduced to provide compatibility between
the VIC
20 and Commodore 64 computers. If you are using the VIC 20
alone, you can use either disk drive. ExceptJor this compatibility difference,
the two disk drives are identical.
All the information in this book applies to both new and old units of the
1515/1525 printers and the 1540/1541 disk drives.
