Presently, there is no other way besides a motherboard swap, but there should be plethora of 25 MHz accelerator cards for both the '030/882 and '040 processors out any time now. >2. What's involved in going from 50MB HD to 100MB or greater? Is >there room and controller support for an additional drive? Whose? The built in SCSI controller allows up to 7 more drives to be daisy-chained externally. Also, there is one unoccupied internal bay, in which you could place an internal 3.5 inch SCSI hard drive in place of one of the external 7 drives allowed. Other drive options include hard cards which are hard drives on cards that fit into an Amiga expansion slot. These are more expensive since they also have a drive controller built in, whereas SCSI drives don't. >3. What's needed to upgrade to Unix? I gather that it's not available >(at least unbundled) yet from comp.unix.amiga... Are all the guys who >have it developers? Commodore's UNIX bundle (not yet released, but very soon). Includes a Q150 tape with all the software needed, UNIX ROMs to be inserted on the A3000 mother board, and manuals. (Note: these are just my observations from the general news I've heard and not exactly what the bundle might contain.) >4. Which DOS ROMs will I find in a new A3000/25-50? 2.0X ? None. There is a patch ROM installed which causes the computer to load the DOS from hard drive. The actual 2.0X ROMS are suppose to be out "soon." 2.03 (disk) is available to A3000 owners, and 2.04 (Beta) is available to developers. >-- > > - Scott >------------------------------------------------------------------------------ >M.
