Z80 STARTER KIT单板机(美国SD SYSTEMS公司)具有Z80 CPU、四通道定时计数器CTC、双通道可编程接口PIO以及静态RAM和电改写只读存贮器EPROM可扩;设有EPROM编程器和音频盒带接口;按键共设28个(12个为功能键,16个为数字键/寄存器键),并有6位七段数码显示器等。 ZBUG监控程序共2~K字节,固定在8316掩膜只读存贮器内。ZBUG具有先进的诊断功能,当单步或中止用户程序执行时把当时CPU所有寄存器的内容压入堆栈保存,断点最多可设5个,对所有存贮器单元、通道和CPU寄存器都可进行检查和输入或修改,唯修改
Z80 STARTER KIT SBC (SD SYSTEMS, USA) with Z80 CPU, four channel timing counter CTC, dual channel programmable interface PIO, static RAM and electrically rewritable read only memory EPROM expandable; EPROM programmer and audio A total of 28 buttons (12 for the function keys, 16 for the number of keys / register key), and six seven-segment digital display. ZBUG monitor a total of 2 ~ K bytes, fixed in the 8316 mask read-only memory. ZBUG with advanced diagnostic capabilities, when the user step by step or abort the implementation of the current CPU when all the contents of the register into the stack to save the breakpoint can be set up to 5, for all memory units, channels and CPU registers can be carried out Check and enter or modify, only modify
