A few days ago a friend sent me a link for an Apple II Raspberry Pi emulator.As far as I can see, it's a linapple emulator, placed in the Raspbian startup sequence, to get faster boot time.It is a free open source emulator, so you can download, record it on a micro sd card and use it on your raspberry pi if you like.I tried it on Pi3 and it works without any issues.It launches directly in DOS 3.3 and from there you can use a large amount of software (mostly games), found on this micro sd card image.
Here's the link:

Thanks for sharing!
Not sure if this is the same link that's being sold on eBay for $5 ... that's been available for free for some time now.
Thanks again.
