NIGHT STALKER
After the obvious ADB hack, which has already been done and is well documented:
Hacking the modem connector's port A signals to the outside world as the second serial port might be an interesting exercise.
Having the roots of the 150 in the PowerBook Duo 230 presents some interesting avenues of exploration:
For more interesting possibilities, the first thing that comes to mind would be the GSC ASIC based LCD/VRAM Display sub-system.
___ Is the 2bit/2 level grayscale output a limitation of the LCD or the VRAM frame buffer?
______If it's the LCD spec, this hack is a non-starter
______If the limitation is the paltry amount of VRAM provided for this LEM, it becomes an entirely different story:
PiggyBacking VRAM to match the Duo 250's (also GSC based) VRAM allotment and patching the additional signal lines to the VRAM ICs from the GSC shouldn't be an insurmountable task. This could upgrade the 150 to the Duo 250s 4bit/16 level grayscale output.
