The Bridge 3C seems to be a rebranded 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
