I'm here only out of curiosity, and with a couple of ideas that I might try to put to work sometime in the near future. So I didn't had your kind of problems yet. But by what I've seen the MPLAB tool is not that complex, but might need some study. But, it ocurred to me that you may try to do it tha way I did it myself in my first year at the university. I leartned to program the Intel 8085, by coding it all in HEX by hand (of course I'm not refering to programs bigger then 256 ~ 512 bytes. Its a simple process, you write your program using the mnemonics (one at a line) and them assemble it by writing the hex code for each instruction and counting the addreses used by that code. After a couple of programs you start to creat the HEX image out of your memory only. The only tool you need is a table with the HEX codes for each instruction. Some of you, younger ones, probably didn't even know that there was a time when things were done this way, but I really did it (and the others students also) around the year 1882/83, and a lot of people did it as a way of life, hardcoding soma KB of program and data that way. Think about it, and you probaly recon that it pays to dedicate one or two weeks to study the modern programing/debugging tools at and :-). Best Regards Jorge F
