DCGrendel has released his Apple ][+ Emulator for Dreamcast, this version is really only for those with coders cable/BBA and a Keyboard but it is great nonetheless, heres what the great man said:

I’ve released the first version of my emulator here.
Features:
Text mode
Lo-Res graphics
Hi-Res graphics

The disk & sound features didn’t make it into this version, but will likely make it into the next release. This requires a Serial cable, BBA, LA, or other upload/debug device supported by dcload. Also required is a keyboard. This release probably only works on TV’s but might work on monitors (dunno, my vgabox == dead)

So for anyone wanting this emulator to try its not on DcGrendels Site but on the http://www.consolevision.com main page.
