一位机由于简单可靠而日益得到广泛应用。在其应用中遇到的问题之一是一位机程序的调试。一种办法是将编制好的程序固化到EPROM 中调试,当程序较长时,常须多次擦除和修改。现市场出售的一位机,有部分产品是带有内装编程器的,无论是用一台还是用多台,编程器的使用效率都不高。现用一台Z80单板机,把一位机程序存贮在RAM 中,在一定的软硬件支持之下(?)就能代替一位机的(?)(?)ROM(?)使程序 One machine is gaining popularity due to its simplicity and reliability. One of the problems encountered in its application is the debugging of a machine program. One way is to cure the programmed program to EPROM debugging, when the program is long, often have to be erased and modified multiple times. Now a machine for sale in the market, some products are with a built-in programmer, either with one or with more than one, the programmer’s use efficiency is not high. Now a Z80 single board machine, a machine program stored in RAM, under certain hardware and software support (?) Can replace a machine (?) (?) ROM (?) To make the program
