- Brainstorm Products demonstrated an innovative bus accelerator upgrade for
- compact Macintoshes which delivers Mac-II performance for only $249.
-
- Unlike existing accelerators for the Macintosh, the Brainstorm Acceleratorâ„¢ not
- only adds a specially designed high-speed 68000 processor clocked at 16MHz but
- also re-configures the Macintosh bus to run at 16MHz, allowing memory and
- input/output chips on the Mac's motherboard to run at the same speed as the
- 68000. Existing accelerators do not increase the operating speed of the bus
- beyond its original clock rate of 8MHz, and are thus forced to slow down to
- accomodate the slower memory and input/ouput chips on the motherboard.
-
- The Brainstorm Accelerator triples the speed of graphics operations and
- increases SCSI hard drive transfer rates by as much as a factor of five.
- Computationally intensive processor tasks, such as re-calculating a complicated
- spreadsheet, are accelerated by a minimum factor of of 250%.
-
- At the core of the bus accelerator's design is a proprietary high-density
- Application Specific Integrated Circuit (ASIC), which takes control of key
- timing signals on the Macintosh motherboard. "The bus ASIC and a 68000 at
- 16MHz allows a Plus or SE to run 28% faster than a Mac-II; it also reduces our
- design to a two chip system, which is super-reliable and costs less than a
- fourth of comparable 68020- or 68030- based systems," said David Zampino,
- Brainstorm president.
-
- The Brainstorm Accelerator for the Macintosh Plus is scheduled to ship in
- mid-February, while a version for the SE is to be available in May. A version
- for the Macintosh Classic is also planned, although the company has not set a
- precise release date. Under development are options to add a 68882 math
- coprocessor and to upgrade to a 68030 CPU, both of which will be simple plug-in
- upgrades.
-
- Brainstorm Products has been developing hardware upgrades for the Macintosh
- since 1985. The company has been shipping its high-reliability Brainstorm
- Memory and SCSI upgrades since 1987.
