At it's conception, the Color Film Recorder (CFR) was designed and developed at CELCO's Mahwah, N.J. facility. Paul Constantine was the project supervisor as well as a contributor to hardware design. Carl Ludwig was the engineer who designed the color processor board and other electronics involved. John Dodd wrote the software to run the film recorder on several platforms. Software was originally written for DEC PDP-11 computers using PAL-11 and MACRO-11 languages to run under RT-11 and RSX-11 operating systems. Software for DEC's VAX computers was written in Fortran. Software for the PCs was and still is written in the C/C++ programming languages with dma board drivers written in assembly. The ground-breaking movie "TRON" was produced on a CFR from the Mahwah facility. Space Telescope Labs, in Baltimore, and NASA are just a couple of other early CFR customers. CELCO-PD eventually took over CFR production and began supplying movie makers CFR systems with software transported to, modified for and written for the SGI platform. John Pielka (Mahwah, N.J.) was responsible for breadboards, circuit board layouts and prototypes. As well as being a Field Service Rep for CELCO, Austin Williams also contributed to hardware and software enhancements.
