Assembling of homemade mobile 6502 computer: PERSEUS-9
PERSEUS-9 is a homemade mobile 6502 computer.
I have built myself a dual-CPU mobile computer using a 6502 CPU. The purpose is to use a homemade floating-point interpreter for convenience.
The 1st CPU runs the interpreter in the main computer part, while the 2nd CPU acts as an I/O processor for the keyboard and LED display module.
Specifications, Dimensions: 262 mm x 182 mm x 55 mm, 1.8kg. Enclosure material: die-cast aluminum. Power source: 5V power supply or Ni-MH battery x 4 . CPU: R6502A x 2 (clock 2MHz). Main computer memory. Battery backup SRAM 16 kB (user program, system variable). PROM 8 kB (interpreter system). Display: 40 x 7 characters LED display (HCMS-2912 x 35). Keyboard: 48 keys, (DS660RCW x 48).
System software: homemade floating-point interpreter, single-precision type, with built-in elementary functions.
A detailed description including schematics and source code is available on Hackaday and an article on gajethub..
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
