Since some of you have wondered why pay such a high price for a C= vga adaptor; Commodore initially released the adaptors with the A4000 but later found that the original design caused genlock problems, etc. with the Video Toaster 4000 board. I believe the -02 revision is the fix for this problem. I have a few of the earlier -01 revisions and have noticed no problems with everyday use, but then again I don't have a Toaster 4000 board. Perhaps there's a Toaster user out there who could verify this.
