The geoRAM acts like the 1750 with the exception that since it lacks a controller chip the DMA options are lost which means that certain applications, such as screen refresh in geoPaint, will be slower than the 17XX using DMA to move data. The geoRAM is only compatible with GEOS and comes with an upgraded version of GEOS (2.0R), which contains a new kernal, configure, and RAM driver. ------------------------------------------------------------------------- Doug Curtis GE Medical Systems UUCP: {sun!subrew|crdgw1}!gemed!altair_4!doug -------------------------------------------------------------------------
