Can't you just use a 12F508, if you want flash?

It's all mentioned on page 2 of the link you posted;
**broken link removed**

Also on this page of the same site:
**broken link removed**

That code is horribly written. Not a single variable anywhere and no config values. Hopefully it works with an 84 as advertised.
