单板计算机紧凑、灵活、实用、价格低,在国内已得到广泛应用,但由于它的软硬件资源有限(如单板机一般不具备硬拷贝、GRT等外设,也不配备编辑、汇编、反汇编、数学计算子程序库等软件),因此为系统的开发带来一定困难。TRS-80微机系统具有较丰富的软硬件资源,是目前国内拥有量最大的微计算机系统之一,但它没有EPROM写入装置等。我们用公共扩充存贮器作为TRS-80与TP-801单板机的公
The single-board computer is compact, flexible, practical and low-priced and has been widely used domestically. However, due to its limited hardware and software resources (such as single-board computers generally do not have hard copy, GRT and other peripherals, nor are they equipped with editing, assembly, Assembly, mathematical calculation subroutine library and other software), so for the development of the system to bring some difficulties. TRS-80 microcomputer system has a wealth of hardware and software resources, is currently the country’s largest micro-computer systems, but it does not EPROM write devices. We use public expansion memory as the TRS-80 and TP-801 SBCs
