Did both the VTech Laser 200 and Mattel Aquarius include modem capabilities?
VTech Laser 200 The VTech Laser 200 was an early 8-bit home computer from 1983, also sold as the Salora Fellow (mainly in Fennoscandia, particularly Finland), the Seltron 200 in Hungary and Italy, the Texet TX8000 (in the United Kingdom), and the Dick Smith VZ 200 (in Australia and New Zealand).
Bell 202 modem The Bell 202 modem was an early (1976) modem standard developed by the Bell System. It specifies audio frequency-shift keying (AFSK) to encode and transfer data at a rate of 1200 bits per second, half-duplex (i.e. transmission only in one direction at a time). These signalling protocols, also used in third-party modems, are referred to generically as "Bell 202 modulation", and any device employing it as "Bell-202-compatible".
