Hello All I am right now using an In Circuit Programmer from Ludipipo together with the PicSer windows software from Sistudio. I worked fine with my 486DX2 but after I have got my Pentium 233 it will not work. I am able to do a correct blank check but I always receive an error when I try to program the 16C84. Are you able to help me or do you have another ICP or some other software which can work with a Pentium and Win95.
