Ok. Here's everything you need, most of which was already "given" to you in previous posts. You'll need to download ASM51 from the link below, assemble the program, program your chip and build the circuit. How's that for service! Of course it's not a 89c52, but you didn't mention that anyway. I couldn't find the datasheet for the LT1059ND, but maybe someone else will "give" it to you.
