===Connectivity===
The MessagePad 100 series of devices used Macintosh's proprietary [[serial port]]s&mdash;round [[Mini-DIN connector|Mini-DIN 8 connectors]]. The MessagePad 2000/2100 models (as well as the eMate 300) have a small, proprietary ''Newton InterConnect'' port. However, the development of the [[Apple Newton|Newton hardware/software platform]] was canceled by [[Steve Jobs]] on February 27, 1998, so the InterConnect port, while itself very advanced, can only be used to connect a serial dongle. A prototype multi-purpose InterConnect device containing serial, audio in, audio out, and other ports was also discovered. In addition, all Newton devices have [[infrared]] connectivity, initially only the Sharp [[Amplitude-shift keying|ASK]] protocol, but later also [[IrDA]], though the Sharp ASK protocol was kept in for compatibility reasons. Unlike the Palm Pilot, all Newton devices are equipped with a standard [[PC Card]] expansion slot (two on the 2000/2100). This allows native modem and even [[Ethernet]] connectivity; Newton users have also written [[device driver|drivers]] for [[802.11b]] wireless networking cards and ATA-type [[flash memory]] cards (including the popular [[CompactFlash]] format), as well as for [[Bluetooth]] cards. Newton can also dial a phone number through the built-in speaker of the Newton device by simply holding a telephone handset up to the speaker and transmitting the appropriate tones. Fax and printing support is also built in at the operating system level, although it requires peripherals such as parallel adapters, PCMCIA cards, or serial modems, the most notable of which is the lightweight Newton Fax Modem released by Apple in 1993. It is powered by 2 AA batteries, and can also be used with a power adapter. It provides data transfer at 2,400 bit/s, and can also send and receive fax messages at 9,600 and 4,800 bit/s respectively.
