I don't have the Go67 emulator, so I cannot test it.

Following the 7 digit header in line 0, 112 program steps are coded in lines 1-32
Every two lines represents a 7 byte register for 7 program steps. The 7 program steps are coded in reverse order in the two lines. The first program step is coded the last two digits in the second line.

For comparing the codes you can download the HP-67 table of program step codes

Thank you so very much for all of that. Yes, I suspect Bill will attempt to decode header info in such an incremental way.

The bee in my bonnet remains about where in the .pck files card font/colour and protection status is encoded. Those features are specific to the emulators. In the really calculator and cards, colour is immaterial and protection is conferred by snipping the corner.
