Gene, with some "search and replace" and features of notepad++ I was able to generate a standard text file which is attached here. Here are my comments.

Chess: The file contains the original version that prestores all moves in 25 data registers. I recently posted a shorter version that requires just one single data register, using the same output format as the original program. There also is a version that displays moves in a more readable form (cf. here). That's the "CH_41c" version. Post #5 has the version with simple HP67-style output attached ("CH_41").

Space War: I am not sure about the memory usage of this program. Are all 26 registers used? At the first glance I only see registers up to 9 and then 20...25.

Golf: I think it's quite difficult to translate the original 67/97 version. Especially the "print stack" function should be replaced by something different, for instance labelled output. Also some other improvements can be applied (e.g. the last eight steps are simply 9 ST/24 ST*21).

I think a common RNG would be great. This and a SEED function that allows to reproduce a given sample game. Which also means that all "Seed?" prompts and the respective routines can be removed. And of course these functions could be used for further user-programmed games as well.

The games included in the ROM would simply call the RNG instead of their own code. This can be changed easily without much effort.
