I would have thought that ANY 16C84 programmer would work just fine with a 16F84 part. The only difference is the power up timer bit, which has to be inverted for the 16F84. The code protect bits are another small difference, in that more bits are set with the F84, that usually wouldn't cause a problem though.

Richard Skinner rwskinner@worldnet.att.net ---------- From: Richard Spooner To: PICLIST@MITVMA.MIT.EDU Subject: MAPLIN PIC Programmer Date: Tuesday, January 06, 1998 5:31 AM I am new to the world of PIC so please excuse any dumb questions... I have a MAPLIN PIC 16C84 programmer (designed by David Tait). I understand that Microchip no longer supply the 16C84 as it now replaced by the 16F84. Is it possible to modify this programmer to cope with the 16F84. If so could anyone suggest where I might find details of such a modification and any other related information.
