Just did one myself. Uses FDTI, 16F628, xtal, handful of passives and 1 transistor. High voltage programs 12 18 28 and 40 pin PIC flash chips in a 40 pin ZIF. Can also program most C series if external 13V supplied. Also has PC control of MCLR. -- Best regards Tony mICros http://www.bubblesoftonline.com mailto:sales@bubblesoftonline.com -- http://www.piclist.com#nomail Going offline?
