- It is in fact a C64 emulator for the PC. This is the relevant information

- I run the emulator on a PC with a Hercules graphic card. It did not
- work on another PC with both Hercules and VGA installed.
- I have not used any programs exept the machine language monitor with it yet.
- To transfer programs one would have to copy a complete image of a 1541-disk
- to a 170K file on the PC.
- The emulator seems to be rather slow and in opposition to what is
- written in the doc file the bank switching seems not to work properly.
