MC145443P DIP20 SINGLE CHIP MODEM BELL 103 MOTOROLA

Bell 103 Modem. Model B202.v103 OEM Bell202 Modem Module The eStore SCADAmetrics This started the upward trend to faster modems using all sorts of techniques (fancy modulation) to get the speed up. Description The MT3530 is a ISO2-CMOS single chip full duplex FSK modem

Its baud rate is 300 bps, with a leading space and a trailing mark after each 8-byte and no parity bit. Later (in the mid 70's) ICs and such allowed for more complex modems, and synchronous data transmission, even if converted back to asynchronous start-stop communications (Bell 212 modems)
