[go67/97 for Android] Creating .pck files in a text editor?

[Bill (Smithville NJ)]

I've spent a little time reviewing the layout of the PCK file and think I have it all figured out with the exception of the "Header Record" - the first record of the data stream. From reading the HP-67 manual and a HP Digest article, I see that the 28 bit record stores the data on whether it's one or two sided, data or program, status of Flags, status of Trig Mode, display format, etc. But I haven't found any reference to how the bits are stored and what each bit means.

And the Emulator may also be storing some data in this header.

Does anyone knows the format of the Header Record that is stored on a Card?

With that info, I could then create a program to read the PCK file to generate a text file program listing, and vise versa.

Appreciate the help.

Thanks,
