 Hi Guys !

What do you think of this auction ? It looks too good to be true.

X68000 personal computer is called, "X68K" or "no good good" is called, is the PC that are loved by many people today.

Probably true.

But I think it's useless for being used as duplication,  simply because most of the components used in nereid are no more available nowadays !

He just sell it for educational purpose : the core logic design (the huge ispLSI2128 in center) may be reused as a base to newer design. It's a  reprogrammable component called a CPLD, used to translate the x68k ext signals bus to slave components. It also contains a dram controller for FPM dram plus some others functions specific to the x68k (address decoding and auto-vectored interrupts provider)
