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.
The Hayes Transet is a communications buffer that works with printers as a print buffer and with your modem as a mailbox. It includes sophisticated internal routing that allows data from one of it’s three ports to be sent to any other port (or all ports).
The Hayes InterBridge is “an inter-connecting ‘bridge’ that allows users of an AppleTalk network to tie into other AppleTalk networks.” This niche product was sold by Hayes in 1987 for $799 retail. There’s not a lot of information about this device left around so this page is an attempt to collect what I can find.
