    Minimal Front Panel Design

    LEDs via the LEDS-SWITCHES card.

    • D4 = On while fetching instructions
    • D3-D1 = SD card status
      • D3
        • on = SD card installed
        • off = SDHC card installed
      • D2 = Read from SD card
      • D1 = Off when running, On when initialization is in progress
      • D0= Off when running, On when initialization is in progress

    Pushbuttons

    • SW9 - Reset

    Jumpers (J3)

    • J3-1 to -3  - selects drive type
      • J3-1 installed = RL
      • J3-2 installed = RK
      • J3-3 installed = RH 
      • J3-4 to J-6 = unused
