    Most of the 892051 programmers on the net are based on 892051, 74373, MAX232 or a couple of transistors. You must be able to get access to a programmer to program the first 892051 before you can use these circuits.:(

    Some of them are here:

    You can get USB and RS232 2051 programmer easily from eBay and it has the bonus that you can program 89C51 and 89S51 in the future like this one:
