The cable is for a serial mouse.

I don't think the unit can back up anything. At least no one has ever figured out how to make it back up. It isn't really a backup device but a computer which is based on Famicom hardware.

> I just got a PCjr and have been using QND to convert NES roms over. I am aware that QND gets the mirroring and masking bytes wrong for mapper 0 and 3 games. I would like to correct these myself. I'm familiar with hex editing but I just need to know which byte offset these are at and what the correct bytes they should be changed to.

> Also, when I received my PC jr it came with a small adapter cable. One end plugs into a joystick port but the other end is a male 9-pin D connector. What's this for? A joystick adapter I assume, but for what? Sega? Atari? I'd rather not randomly plug things into it and fry the machine.

> Finally, the manual is in Chinese, how do you get it to backup a cartridge?
