Now, talking about Bitscope... Actualy I thought of buildng one myself. I would like to get some input from you who have aleady done this. Did you bought the complete kit ? Or maybe just the PCB ? Or even a pre-built, in-a-box Bitscope ? And what about the ADC and other "special" IC's used, are the available "down-town", or should I get them from the Bitscope site ? (No, I havn't checked with e.g. Farnell...) I'v checked the Bitscope site, and saw that it used the now rather old F84 (or F84A it seems). Is the cuircit still up-to-date ?
