My USB-serial converter is missing its driver, so I can't test it right now. --Bob >On 3/9/06, Bob Axtell wrote: > = > >>One of my CZ ICD2 clones broke, so I decided >>to take a chance with a Hong Kong Co, "Etekronix", >>sold on EBay called "Mini-ICD2". >> >>What is appealing is that for less than $50, >>you get a working ICD2 powered by a spare >>USB port PLUS a programming module complete >>with 40P ZIF socket.
