New version with 7406 hex inverter and piezzo buzzer now available! Option B of Pi1541 is now supported.
This is my own design of Pi1541 vertical hat for Raspberry Pi Zero 1 and 2.
The board is professionally SMT-assembled. Discrete level shifter is integrated on the board.
My board and cable has support for SRQ. SRQ is used by Commodore 128 for selected drives for faster transfer speeds. Pi1541-firmware doesn’t have support for SRQ as of yet but if the support is implemented in the future my hat is ready for it.
As Raspberry Pi Zeros come without pin header installed (WH model is only version with preinstalled header) I will include 2×20 pin male pin header with your order.
You can use my Cassette Port USB Power Adapter to power this.
The hat with blue OLED-screen.
Spacers, screws and nuts to secure the board to Raspberry Pi Zero.
60 cm IEC-cable.
2×20 pin male pin header.
Preconfigured software for RPi Zero 1 and 2. Just extract to root of SD-card and you are good to go. Piezzo buzzer is enabled by default.
RPi Zero 1 has a base clock of 1 GHz. Overclock to 1.1 GHz is required for Pi1541 and preconfigured software here overclocks the RPi Zero to 1.1 GHz. It may not be enough for some fastloaders. If the loader of Ghosts’n Goblins Arcade or Commando Arcade crash you need to overclock RPi Zero more. Open options.txt and change the arm_freq=1100 line to 1150. If the loader stil crashes try 1200. Please nore that at 1200 MHz RPi Zero 1 starts to run very hot and installing a heatsink is highly recommended. RPi Zero 2 has a four core cpu and doesn’t have this issue.
Make sure that the memory card is formated as FAT32, Some memory cards larger than 32GB come preformated as exFAT and RPi can’t boot form exFAT partition.

One of my customer designed a case for this (Thanks William!) Here is the STL-file if you want to print your own. I don’t sell ready made cases because it’s not my design.
If you previously bought the version that supports only Option A you can download the preconfigured software from here.
