I have two of the 7200 upgraded last weekend by following Tommy N. Tyler's instruction on 31 Mar 2001. Thanks Tommy, It is a very good instruction. But I do encounter a small problem for a long while before I can get it working. Which is the pin 5( reset line) that goes to R36. It doesn't work. When I use DDM to measure it. one side of R36, C11 and J1 all go in the same point. Whin I try pin 5 to C11 the same point it also not working. But when I try pin 5 to J1 the same point as R36 & C11. It works!
Thanks again Tommy
Felix
