Hi, 2 weeks ago I wrote a mail to list where I explained my problems with TT1.5 card using firmware 261d and 261f. After a lot of problems with 216d and upcoming problems with 261f I decided to send the mail. Now, 2 weeks later I am sure that 261f is _much_ more stable for me. The problems are still there but are significantly reduced. Thanks a lot for it! I am looking forward for the next firmware release. 2 qustions: Is the firmare open source? Is there any block diagram of whole card? Regards Ralph
