I got my hobby time to design and build the early 1976 Microprocessor 6802 single board computer. The 6802 chip is NMOS, drawing much power compare to CMOS. The main platform is the same as 6502 kit. The 6802 has two accumulators, 16-bit Index register 16-bit stack pointer and more relative branch instructions. The 6802 chip is software compatible with 6800 microprocessor. I have also added the brownout reset chip, so the kit will properly reboot after brownout condition. 

Hardware features:
  • CPU: Motorola 6802, NMOS 8-bit Microprocessor @1MHz clock
  • Memory: 32kB RAM, 16kB EPROM
  • Memory and I/O Decoder chip: Programmable Logic Device GAL16V8D
  • Display: high brightness 6-digit 7-segment LED
  • Keyboard: 36 keys
  • RS232 port: software controlled UART 2400 bit/s 8n1
  • Debugging LED: 8-bit GPIO1 LED at location $8000
  • Tick: 10ms tick produced by 89C2051 for time trigger experiment
  • Text LCD interface: direct CPU bus interface text LCD
  • Brownout reset: KIA7042 reset chip for power brownout reset
  • Expansion header: 40-pin header
