Oh, the kitchen table activity still goes on. More and more manufacturers (I know of Philips and Atmel) are removing parallel programming info from their data sheets because of all the grief they get from those that insist on making programmers on their kitchen table. The official policy is "we will privide parallel programming info to certified programmer manufacturers". Why, oh why does this activity still go on when there is a plethora of ISP chips available?
