Description

The Tang Nano DCJ11MEM project is an attempt to implement the memory system and UART of the DEC DCJ11 CPU on an FPGA (TangNano20K).  More information can be found at github.com/ryomuk/TangNanoDCJ11MEM

Features

  • Only peripheral circuits are implemented on the FPGA, the CPU itself is real
  • 32K x 16bit of RAM
  • Socketed 18Mhz Oscillator for experimentation on clock speed
  • Emulated Devices
    • Paper-Tape Reader/Punch (PC-11),
    • Disk Drives (RF11, RK11)
    • External Computing Units (KE11-A)
    • Clocks (KW11-L)
  • Currently there are 4 operating modes
    • Bare metal
    • BASIC loading from a PC11 tape reader emulator
    • Unix V1
    • Unix V6 (Experimental)

Full operation requires, in addition to the Tang Nano DJ11MEM, a DEC DCJ11 CPU, Tang Nano 20K, tangNano-5V and optionally a 5v DC power supply (5.5mm OD x 2.1 mm ID with center positive).

The Tang Nano DCJ11MEM is the design of the INCREDIBLE Ryo Mukai (github.com/ryomuk)!
