Has anyone seen the new GEOS REU called GEORAM 512 (I believe)? If so, can
it be used for other things besides GEOS? 512K is more memory than the
Commodore brand REU isn't it?

I've heard that GEORAM does indeed have 512K.... but it lacks the
high-speed memory-moving hardware that make the 1750/64 really useful
outside of GEOS.
There was information on QuantumLink (I used to be a member) a while
back on how to put 512K in your 1764.... I never tried it, but I can
dig it up and mail/post it converted and UUEncoded.
(Will this be a good way to distribute GEOS stuff? Run it through
Convert and then UUEncode?)

Almost two inches of the end of the board that plugs into the expansion port sticks out of the end of the case, giving the unit a crude unfinished look. So far, GEORAM works only with GEOS. It lacks the custom DMA controller which would make it compatible with the Commodore line of REUs. The rumor mill has it that some third party developers might consider developing software that will work with it, but I wouldn't hold my breath. The Commodore 1750 REU has 512K, and the 1764 can be upgraded from 256K to 512 K with the addition of another bank of 256K RAM chips. I think Berkeley SoftWork's advertising is far from truthful. The "reviews" they quote in their GEORAM ad are general statements about how well GEOS runs with the Commodore RAM expanders. ******************************************************************************* * Randy Winchester * randy@athena.mit.edu * PO Box 1074, Cambridge, MA 02142 * *******************************************************************************

The new GEO RAM is not supposed to be usable by anything but GEOS, however I have not seen one, so I cannot support or refute this claim. I will guess, however, that it can only be used by GEOS. Yes, the 512K RAM is more than the standard 1764 REU, however this REU can be simply modified to handle 512K instead of 256K (adding 8 256K chips internally, thereby voiding the warranty). Another modification (quite more complicated) will allow this REU to handle 2MEG RAM. If interested, I will send the procedures for both modifications to the mail servers.

I'm planning on digging up a 1750 this summer, and 2 meg would be GREAT!!! I'll bet it would be awsome to use with any BBS!
