在教学和科研中,把十六进制机器码输入TP801机必须细心触键。将调试通过的程序存贮起来又要使用盒式磁带机,工作量大,且不可靠。我们开发了APPLEⅡ与TP801机传输数据的并行高速接口,实现了APPLEⅡ对TP801机的DMA操作。可以把APPLEⅡ汇编完成的机器码程序或软磁盘中的数据传送到TP801机的RAM区,也能把TP801机中的程序传送到APPLEⅡ机的RAM区或再形成文件存到软磁盘中,并且两机取长补短,可以用于工业控制系统中,TP801机利用APPLEⅡ
In teaching and research, the hexadecimal machine code input TP801 machine must be careful touch. The debugging process through the storage and use of the cassette tape drive, heavy workload, and unreliable. We developed a parallel high-speed interface between APPLEⅡ and TP801 to transmit data, and realized the DMA operation of APP80Ⅱ on TP801. APPLE Ⅱ can be compiled to complete the machine code program or floppy disk data sent to the TP801 machine RAM area, but also the TP801 machine in the program sent to the APPLE Ⅱ machine RAM area or re-formed file stored in the floppy disk, and the two complement each other , Can be used in industrial control system, TP801 machine using APPLE Ⅱ
