# Opus Discovery Emulation

By default, Fuse emulates the Opus Discovery interface with the optional 2k RAM expansion and a second 40 track single sided disk drive.

See the Disk File Formats section for more details on supported disk file formats. The Opus Discoveries’ printer port is also emulated for output only. (See the Printer Emulation section for more details). The Opus Discovery may only be used with 16K, 48K, 128K, TC2048 and +2 (not +2A) emulation.

To access disks, use the same syntax as the Interface I and Microdrives.

## ROM File

The ROM file for the Opus Discovery is not freely distributable and so is not included in this package. In order to use the Opus Discovery emulation you will need to download a copy of the ROM file and use the Preferences > ROM dialog to configure the file for use with Fuse.
