With GCR coding (change in the output -> '1', no change -> '0') the efficient bit rate could be e.g. 4/5 of that, which means 2205 bytes per second, or 29.7 seconds to fill 64 kilobytes. And you could store two programs per CD track: just select the channel (left/right) on the adapter that plugs into the datassette port, and that's it. This would fit about 149 programs per CD. If the limit is 99, then one could store a normally SAVEd loader in the beginning of each track as well. Hmm, Levente, didn't you say that you have more spare time now? :-) Marko - This message was sent through the cbm-hackers mailing list. To unsubscribe: echo unsubscribe | mail email@example.com.
