What makes this solution so interesting is the level of emulation you can reach: it’s really perfect and you can load whatever software for Commodore 64/128/Vic20/16/Plus4 as the real floppy drive.

The unit i'm selling it's assembled, tested, with both IEC connectors installed, piezo buzzer and oled display. The hex inverter is original, not a fake one.

These items are not included but are required to use:

• Raspberry Pi 3B with 2.5A power adapter

• MicroSD-card

You also need a 6-pin serial cable that is available as product option or you can use the one that came with your 1541 (if you have one).

You can read about his project, download the software for the sd-card and understand how it works HERE

These are the options to set in the file options.txt for this hardware configuration:

// If you are using the split line hardware option (ie Option B) then you need to specify this option

splitIECLines = 1

// If you are using a LCD screen then specify it here

LCDName = ssd1306_128x64

// If you are using I2C LCD you can optionally change what pins it is connected to.

// (defaults to 0 for non-split lines (Option A) or 1 for split lines (Option B))

i2cBusMaster = 0 //SDA - pin 27 SCL - pin 28

i2cLcdAddress = 60 // I2C display address in decimal and shifted. 60 == 0x78, 61 == 0x7A

i2cLcdFlip = 1 // Rotate i2c LCD screen 180 degrees

i2cLcdOnContrast = 127 // Allows you to adjust the contrast on your i2c LCD screen

// If you have hardware with a piezo buzzer (the type without a generator) then you can use this option to hear the head step

SoundOnGPIO = 1

SoundOnGPIODuration = 1000 // Length of buzz in micro seconds

SoundOnGPIOFreq = 1200 // Frequency of buzz in Hz
