I have downloaded a simple simmulator fo 8085 kit from http://www.vikaspatel.org/ ,which can progrmme in hex only ( It has a-z and 0-9 keys with reset,execute etc. keys) Now I have all hex codes for all memnomics but I don't know how to start, I mean how to find address of registers and all that begaining stuff, I tried a few example but they did'nt work can any one suggest any link from where I can get any tutorial on how to use the same kind (HEX programme) of kit and begain my first programme!!
