Computer Science | Grinnell College

Notes from Stone: Professor Emily Moore used these floppy disks on the computer in her office between 1983 and 1987 -- a DEC Rainbow 100 with a monochrome, VT-220-like monitor. The Rainbow could boot either into CP/M or into an MS-DOS-like operating system. Much of her programming was done in Pascal or MATLAB, though interpreters for BASIC and Logo are also here. MASS-11 was a document-management system that GCCS (the predecessor of Grinnell ITS) advocated to faculty. Additional information: The 3 1/2" floppies were used on SunOS workstations, as opposed to the DEC Rainbow 100, although the MATLAB code would of course work on any platform with a MATLAB implementation. Notable among the MATLAB programs are visualization utilities Graph2D, Graph3D, solve, integrat, fseq (finite sequences), dirfield (direction fields for differential equations), fingraph (finite graphs). The programs were used in Calculus I and other math classes at Grinnell for a number of years, and were developed by Emily Moore and research students over two summers circa 1992.
