Its his choice, personnally i would not lose time on this, if its not the input parts, bye bye in the bin, Atlas have surely protected the code in the chip ... buying an tl866 adapter etc ... is not worth it in the end.
IF he wants to play at it and have the chance to restart it, go for it. If Atlas doesnt sent him an programmed cpu or the compiled code, he knows what to do.
good luck
I work in a pcb manufacturing plant, we try for 2 hours to debug a board, if not, we recover what we can (big parts, thru hole, heatsinks etc...) we destroy the board and trash it.
