Hi Harald,

Geoff's description is correct. There are 21 programs of 224 steps each in HP-67E available. There are two reasons for differentiating between "program memory" and "program library".

1.) The 10 program memory locations can be accessed by less keystrokes.

2.) The program library locations (up to 100 programs in HP-25E, but only 10 programs in HP-67E) is stored internally in compressed data format mixed with the original HP microcode (PIC flash memory is 14-bit word oriented, 10-bit for HP microcode, 4 bit for program code). This trick allowed me to add 10 more HP-67 programs into flash memory.

The actual loaded program adds one more to a total of 21 programs.

Bernhard

That's one small step for a man - one giant leap for mankind.
