The Bridge 3C seems to be a rebranded [InterSystems DPS-1](/museum/intersystems-dps-1/) computer sold with Televideo terminals.

Apparently the Bridge 3C was delivered with the following software: CP/M 2.2, BMATE word processor, R80 RATFOR preprocessor, FORTRAN compiler, Enhanced FORTRAN, Pascal-Z and C compiler.

The following extensions/options were advertised for the Bridge 3C:\
\- FPP: system calendar, 3 interval timers, one additional serial port, and a 9511 floating point processor with complete software interface.\
\- ROM-EPROM development package including programmer and dual port memory for emulating 2716s\
\- GRX: High resolution graphics package\
\- AD: Hardware and software drivers for 16 channels A/D converters (30 KHz throughput) and 4 channels D/A converters.\
\- MEM: Additional 256 Kb memory\
\- HD: Hard disk drive (30 Mb) with interface and all necessary software updates
