Simply put: I offered you one of my bare-boards, which is designed originally for 8052AH-basic, includes lots of useful goodies and with a tiny amount of hacking works with 80C320 , DS5000, 89C51 (Atmel or Philips), has provision for 64K of RAM, and 64K of EPROM split into two devices (I said it was an old board), and an address generator to map everything above FFXX as IO. All the address/data and control lines are fully buffered and it fits on a eurocard with only through hole chips - apart from the reset genny, which I couldn't squeeze on the revised board any other way. All the AD lines are available buffered on the edge connector - we connect it to a little card frame with other analogue I/O boards to suit the design.

It was the first 8052 board I ever worked on.

It needs +5V +/-15V and a 12,5 Vpp if using.

And you have ignored it, despite Kai asking four times why you haven't talked to me ! If you feel Kai is questioning your credentials, perhaps thats why ?
