DDP-24
Encyclopedia
The DDP-24 was a 24-bit computer designed and built by the Computer Control Company, aka 3C or CCC located in Framingham, Massachusetts. CCC consequently became part of Honeywell in 1967. The DDP-24 was completely transistorized and has a sign magnitude code to represent positive or negative numbers. The processor used binary logic. The DDP-24 used a single address command format and single operation with index and indirect addressing flags. The DDP-24 used magnetic core memory to store data and program instructions. The DDP-24 found use in Space and flight simulators of the mid-1960s and other real-time scientific data processing applications. Of notability, Max Mathews
, considered by many to be the founding father of computer music, used among others, a DDP-224 and a DDP-24 computer to develop his GROOVE
music system, as related by Professor Barry Vercoe in a1999 MIT Media Lab interview. When asked to describe the first MIT experimental music studio, Prof. Vercoe replied, "We began that work when I first arrived in 1971. The first studio we had was in the basement of Building 26, where we had a computer given to MIT by Max Mathews-the Honeywell DDP-24. Max initially developed his GROOVE system on this machine and was kind enough to give it to MIT when I joined the faculty." The 3C DDP-24 used modules or cards called S-Pac’s. These S-Pac cards could be Flip-Flops, NAND gates, Bit Registers etc. and were housed in aDDP-24 S-Bloc card rack.
