M100

Q-BUS SBC

Technology From Mentec

Mentec's SBC M100 is a high performance, quad height Q-BUS board offering customers the essential speed increase you demand without having to change existing proven software. Mentec's advanced "No-Wait-State" parity memory subsystem design coupled with the use of high speed DRAMs, enables all on-board memory to operate at cache speed. This gives all PDP applications a high-performance capability. M100 Processor Picture
The single quad module operates as host processor on the Q-BUS and incorporates DEC's powerful J-11 microprocessor for complete compatibility with all PDP operating systems and software. Special features of the SBC M100 are lower power consumption and increased MTBF due to fewer sockets, chips and discrete components. The SBC M100 also interfaces to the 22-bit Q-BUS and supports block module DMA. This provides for total compatibility with all PDP operating systems and software.

Processor
The DCJ11 microprocessor consists of a control chip and a data chip. The control chip directs the operation of the data chip with micro-instructions. The data chip carries out all logic and arithmetic functions, handles all data and address transfers, and generates most of the signals used for system timing. The DCJ11 also contains an integral floating point processor allowing it to perform single and double-precision floating point operations. The FPJ11 (floating point hardware accelerator) option is also supported.
   
Memory
The module contains 1Mb/2Mb/3Mb/4Mb of Q-BUS cache speed dynamic RAM, one parity bit per byte of data. The module's RAM is accessible by other system devices over the Q-BUS using DMA and block mode transfers
   
LSI-BUS Interface
The module interfaces to the extended LSI-11 bus and can address up to 4Mb of main memory and communicate with other bus devices, e.g. disk controllers (RQDX-3) or asynchronous serial line mux (DHV11). The 22-bit extended LSI-11 bus is completely downward compatible with the standard LSI-11 bus.
