From Issue #22 of GeoWorld, GEOS Hardware News "geoRam" article:
The new geoRAM card uses CMOS chips, which use less power and can
be plugged directly into the C64 without the need for a larger power
supply.
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.

Since you mentioned that the BSW card is slower than Commodore's, that raises another question. In its magazine ads, BSW uses many review excerpts from many computer magazines. Those reviews, however, are fort the 17xx's, NOT the GeoRAM. Does that constitute false advertising on BSW's part? ************************************************************************** * InterNet: bwildasi@silver.ucs.indiana.edu Ben Wildasin * Bang: ...!silver.ucs.indiana.edu!bwildasi * BitNet: indp0080%iubacs.bitnet@uicvm.uic.edu **************************************************************************
