Today I’m going to recap the LCD display on this PowerBook 160. It has a passive matrix LCD display capable of displaying 4-bit grayscale (16 shades of gray). The display was dim before with some severe artifacts (after adjusting the contrast slider) but now it will only show a black screen.
I’ve had this cartridge expander for a few years and always assumed it was commonly known about and that the ROM inside had been dumped. It seems that may not be the case, so this page is to provide the information I have about it.
