Subsystem B
The Master's Touch
Configurations

Random Access Memory: three choices.

The three versions of Subsystem B differ only in memory capacity. Subsystem B70 includes the 4KRA memory module with 4096 words of read/write static memory. Power drain is so low a standard D cell will provide back-up data retention. The 8KRA static memory in Subsystem B70 offers twice the capacity, more address flexibility and even lower power drain than the sum of two 4K memories. It features fully buffered address and data lines, built-in noise immunity circuitry and our exclusive KSET switch to provide card address offset in 1,024 byte increments.

For more programming pleasure, Subsystem B190s 16KRA has 16,384 bytes of dynamic memory. This module is available only in assembled form; fully burned-in and tested, it demonstrates extraordinary reliability. Refresh is invisible, and access is fast, worst case 400 nsec. For all three memory modules, battery connector and recharge circuitry are built-in.

Savings with Subsystem B.

The individual modules of Subsystem B can all be purchased separately, but Processor Technology offers a substantial price reduction on the complete package. One box contains all five boards plus complete assembly and operating instructions. Subsystem B is also available with the modules fully assembled and tested.
