Hi I thought PICers who do not have immediate access to the ETI articles might be interested in the following:- For the sum of 20 pounds sterling, the author offers to program a blank PIC (16C57XT supplied by you) and supply a disk containing the windows host software. However, there is a hex dump of the PIC code in the article but there is no seperate cost given for the host software alone. As far as I am aware, the PCB is not available through the magazine, but there is a good quality copy of the artwork. TTFN Nick
