The Ikonas is a raster graphics system. One of its options is a 68000 processor that can handle peripherals, etc. (It, it is told, can even run UNIX, anybody do that ?) We wish to enhance the functionality of this 68000 option: - Has anyone ever put a 68881 floating point chip on the Ikonas 68000 ? If so, how ? What is the suitability of the Apple MacIntosh and Amiga CPU enhancements, such as the piggy back 68881 or the 68020 clip-ons ? How machine and firmware specific are they ? - Has anyone cranked up the speed of the Ikonas 68000 ? It is currently a 8Mhz chip. Could we put in a 12Mhz, perhaps by changing the memory chips to 90ns ? - We currently use the SUMACC C compiler to write programs for the Ikonas 68000. If we succeed in putting on a 68881, is there a version of the SUMACC or MIT C compiler which can generate code for the 68881 ? Any other compiler suggestions (perhaps the GNU C compiler) ? Thanks.
