Apple Time Capsule Custom Firmware |link| -

A review of custom firmware for the Apple Time Capsule! That's a great topic.

Instead of replacing the firmware, you can gain root access to the existing NetBSD system. This is the primary method for "customizing" the device's behavior. Enabling SSH : You can use tools like the Python utility jcs's scripts apple time capsule custom firmware

Then configure /etc/netatalk/afp.conf to point to /mnt/sata/TimeMachine.sparsebundle. This is non-trivial, but the OpenWrt wiki has a complete afp.conf template. A review of custom firmware for the Apple Time Capsule

The "AC" Models (802.11ac - A1470) – The Holy Grail

• CPU: Broadcom BCM47094 (ARM Cortex-A9, dual-core? No, single-core but powerful).
• RAM: 512 MB (massive for a router).
• Flash: 128 MB (NAND).
• Storage: 2TB or 3TB HDD (3.5" SATA).
• The Verdict: The only viable target. This is the "Time Capsule 802.11ac" (Late 2013/Early 2015). It uses a Broadcom Wi-Fi chipset (BCM4360 for 5GHz, BCM4331 for 2.4GHz). Broadcom is historically hostile to open source, but thanks to the reverse-engineered b43 and brcmfmac drivers, we have partial support.

• Use an external router running OpenWrt or pfSense and connect the Time Capsule as a networked drive only.
• Replace the internal drive with a modern NAS or attach an external drive to a supported router for better performance and flexibility.
