Hi, i've recently come across a pair of 8052 development boards, the only markings on them is EPS.87192, the board contains ram, logic, the 8052, and a eprom zif socket, the board is working and is programmed through a remote terminal in windows, on bootup the board returns

*MCS-51(tm) BASIC V1.1*
READY

i have the manual for programming the 8052 but nothing on the hardware, can anyone help? or does anyone reconise the boards??

Thanks in advance
