- The directory "64prgs" contains some little sample programs to show the
- capabilities of Frodo/Frodo SC. Except for "dadb" and "lrborder" they are all loaded with
- <CODE>LOAD"<name>",8,1</CODE> and started with <CODE>SYS49152</CODE>.
- To do so, you have to set "Drive 8" in the settings to "Dir" and set the
- path to '64prgs' so Frodo will find the programs.<P>
-
- The programs were written by Pasi Ojala, Marko Mäkelä, Andreas
- Boose and me. If you like, you can try them on other emulators or on a real
- C64.<P>
