PERSEUS-9 homemade mobile 6502 computer.
In 2021, I built my own floating-point interpreter system on my PERSEUS-8 computer. However, this system required a serial terminal for input/output, which was somewhat inconvenient to use for programming and calculation whenever I wanted. Therefore, I have developed the PERSEUS-9, a mobile stand-alone computer that can run this system independently. Its features are as follows. (1) PERSEUS-9 will have a keyboard and character display on the chassis panel, which can be used to operate a home-made floating-point interpreter. (2) PERSEUS-9 has dual 6502 CPUs, with the first CPU running the interpreter and the second CPU performing key and display I/O processing. The address mapping of the two CPUs should be the same to facilitate operation verification. (3) PERSEUS-9 shall be a synthesis of PERSEUS-8, 6802 Serial Terminal, and Floating Point Interpreter CI-2 technologies.
