* (c) 1999 R. Offermanns (rolf@offermanns.de)
* based on the aimslab radio driver from M. Kirkwood
* many thanks to Michael Becker and Friedhelm Birth (from TerraTec)
- *
+ *
*
* History:
* 1999-05-21 First preview release
- *
+ *
* Notes on the hardware:
* There are two "main" chips on the card:
* - Philips OM5610 (http://www-us.semiconductors.philips.com/acrobat/datasheets/OM5610_2.pdf)
* (as soon i have understand how to get started :)
* If you can help me out with that, please contact me!!
