A few months ago, I released an initial version of a program I’ve always wanted to have. It’s a programmers reference to the 65xx series of microprocessors, available now in iTunes store (it’s free).
It’s still a little rough around the edges, but I’ve already started an iPad version that looks great, and am adding a ton more documentation on each instruction. The iPad version and an updated iPhone version are slated to be released mid-summer 2014. I know that seems like a long gap in between, but I’ve had to take a break from this to get a number of other projects cranked out.
Update April 2015: Unfortunately, Apple has made a very unfriendly environment, so it’s hard to support older devices. Or really any iOS apps. They keep killing support for older devices, even though my code works on the original iPad, they will no longer let me submit such an app. I do not like this type of behavior and will not be able to afford to the cost of iOS development that can potentially be thrown away by their greed.
