Woodstock Low Power

[PANAMATIK]

Today the HP-67 part of the Woodstock LP circuit got the 15 Standard Pac programs built in.

Besides the 110 HP-67 free user programs you can load the 15 magnetic cards programs of the Standard Pac just by key press. I needed the whole day to enter and verify the programs. The Standard Pac manual as part of the HP museum disk, is not readable enough to be sure to enter all program steps error free. The procedure was to read the magnetic cards with an original (card reader repaired) HP-67. Then enter the same key codes manually into the new HP-67 LP calculator. Then read the programs from LP flash memory to PC and convert them to C source data. This data is then compiled to the LP flash burning tool and will be integral part of every LP circuit.

Still some bugs to be fixed in HP-55 emulation, but nothing difficult. The most annoying error, which costs me several weeks, I finally could track down. Microchip admitted a serious compiler error in their flag ship XC8 compiler, which I reported to them last week.
