Configuration guide

SE Basic IV can be configured using an optional SYSTEM.PRF file in the /SYSTEM/PREFEREN.CES folder. This file accepts line endings in Macintosh (CR), UNIX (LF) and Windows (CRLF) line endings.

The config file currently supports three settings:

• cp: code page (2K bitmap font file)
• kb: keyboard (4K or 16K keymap file depending on Uno hardware version)
• ln: language (608 byte message file with required code page in file name)
• sc: scan-doubler control (Uno hardware specific)

Example: Spanish language / Western European code page / V4 US keyboard enabled
