据《EDN》1985年8月第19期报道:DBR50-1M是用于多总线系统的1M字节双总线RAM插件板,它通过在P1连接器上的IEEE-796总线和在P2连接器上执行的总线与单板计算机接口。数据被编成有字节转换或交换的8比特字或16比特字,在IEEE-796通道上锁定的读出运算允许周期重叠。它的其他性能还包括奇偶产生和校验、奇偶检验误差、误差隔离寄存器及突发方式的通行能力。该板体积为12×6.75×0.4时,电压为5V(±5％),电流驱动为3.6A,工作温度在0-50℃之间。
According to “EDN” Issue 19, August 1985 Report: The DBR50-1M is a 1-Mbyte dual-bus RAM board for multi-bus systems that communicates via the IEEE-796 bus on the P1 connector and on the P2 connector Executed bus and single board computer interface. The data is organized into 8-bit words or 16-bit words with byte conversions or exchanges. Locked read operations on the IEEE-796 channels allow periodic overlap. Other features include parity generation and parity, parity error, error isolation register, and burst mode throughput. The board volume of 12 × 6.75 × 0.4, the voltage of 5V (± 5%), the current drive is 3.6A, the operating temperature is between 0-50 ℃.
