The simple version – cf. the posted sample output – is easy, this one is already running. But what about something more legible, closer to standard chess notation?

I admit I do not quite understand how the output of the HP67 chess program is supposed to be read. The original program and its instructions are here. I read the explanation of the white move display several times but I still don't get it, especially the two-digit column of the white piece. The text says "that's confusing (and it is complicated)", and obviously it is. I would like to translate this to something more readable. But for this I have to know how to read the confusing HP67 output. Maybe someone can explain this to me.

Edit: I now begin to understand how it works. The problem seems to be the old descriptive chess notation as it was used in the UK and US some decades ago. I think I will translate the whole program to something more common, close to today's Algebraic notation. For instance instead of "1523" = P-QN3 in descriptive notation the output will be "P-B3" or "P-23".
