I actually found an A to A cable in my Big Box of Cables I Might Need One Day™ when trying to flash my Gotek floppy emulator with FlashFloppy firmware.

I been through about 10 TN-450 cartridges in my Brother printer and can count on one hand how many jams I’ve had. And I’m pretty sure they were all because my kid would take paper out and leave a page sitting crooked in the tray.

Recently had to replace the drum.

I’ve used it and dd-wrt back in the day on cheap crashy routers. Also Tomato.

Haven’t tried it in a long time, but have an EAP225 v2 and v3 I’ve been considering slapping openwrt on.
