About the MiSTer SNAC2IEC PCB
MiSTer SNAC2IEC is an open source PCB design by venice1200, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 50 × 36 mm, with 10 components from 7 distinct parts.
Other key parts include the Breakout_LevelShifter_4-Channel and Breakout_LDO. By type, the board carries 4 resistors, 3 connectors, 2 ICs and 1 capacitor.
It belongs with the retro computing and dev boards & breakouts designs in this gallery.
From the project
Commodore/CBM IEC Adapter for MiSTer FPGA
The Adapter converts the MiSTer FPGA User Port (Serial IO) into a Commodore IEC/CBM (Serial) Bus Port. Use the Adapter to connect a real Commodore Floppy 1541 or compatible devices (SD2IEC/PI1541) to your MiSTer.
I know there are better and faster ways to load a game into a MiSTer's Core, but this is fun 🚀.
Cores and some Hardware Devices are also tested with JiffyDOS 🚀.
