Pi1541-III Disk Drive Emulator for Commodore, Black, RPi3A+

The device is a 1541 disk drive emulator for Raspberry Pi 3A+.

Functionality

Pi1541 allows you to play disk images on Commodore computers using a 32GB microSD card. Compatible computer models:

• Commodore 64
• Commodore 128
• Commodore VIC-20
• Commodore 16
• Commodore Plus4

Design

The set includes:

• Power cable with USB plug for a 5V USB power supply.
• 32GB microSD card.
• Serial IEC cable for the disk drive.
• Knob in gold, black, silver, red, or blue, to choose from.

Technical Highlights:

• Top-notch compatibility:
  Nearly 100% compatibility with the original, including support for many fast loaders, even those with copied originals and demo scene gems. The 6502 code runs in full cycle-exact mode, just like in 1982. Forget about SD2IEC heuristic guessing!
• Work modes like in sci-fi movies:
  The device starts in minimal SD2IEC mode (for browsing PRG and D64 files). After loading a disk image, it switches to full 1541/1581 emulation, enabling data reading and writing with support for multiple channels and sequential files.
• Classy hardware:
  Mounted on a Raspberry Pi 3A+ (a version without RJ45 and 3 USB ports compared to Raspberry Pi 3B/3B+). The PCB is equipped with a logic level converter (5V CBM → 3.3V Pi), IEC connectors, and a chain option, allowing cascading with other drives – both real and emulated.
  Version III features a 1.3" OLED display and a rotary encoder for navigation – browse folders like on a smartphone instead of fumbling with a joystick.
• Media support:
  You can place hundreds of D64 files on the SD card (up to 32GB+), browse them using the Pi keyboard/screen or via C64 commands (LOAD "",8", LOAD "",8,1). Saving is possible, but remember: retro is retro – always make a backup before your cat sits on the card.
• Power and assembly:
  Powered by a 5V included power supply. The compact casing ensures convenience in use.
