[I tried to EMail this, but my post-office couldn't figure out how to get from here to there... So, we post it instead...] Kris, You recently posted a listing in notes: | A few weeks ago, someone posted a 5 byte program that could be entered | into memory with the debugger, and then be saved as a runnable program. | Could someone please send me a copy? The program is quite simple. The assembler instruction is JMP FFFF:0000 Which simply branches to the RESET vector in ROM. The hex bytes which make up this instruction are EA 00 00 FF FF If you want the code to be short (5 bytes), make it a .COM files, not an .EXE file. Good luck.
