4K HP 67 Games rom attached for testing

Ok, so here you go:

zip of HP67 games rom raw files as of 20161104 7pm central time

and

Hopeful text file of game program listings


The text listing includes the global random number generator (LBL S) which expects a seed in register 00. It uses the preferred generator. All programs need to be reshuffled to use 00 as the RN register.

The PI + style RN generators fail several randomness tests. Some seeds repeat the random numbers in a very short cycle or are not centered on a 0.5 mean, etc. A lot of work was done in the PPC Journal on these in the past. The LBL S routine shown here is the one we should use.

Once in a ROM, the XEQ S would really become a TWO BYTE XROM call. Best way to code this is to put in a TIME instruction (which will be coded as an XROM) and then Angel can find the TIME instruction and redirect it to the XROM S it should be.

Another routine LBL L (load?) should be
LBL L
RCL 00
SEED?
PROMPT
STO 00
END

Another XROM call (Let's put DATE in as the placeholder) would replace the XEQ L in the programs.
