As you can probably tell from the information at the bottom of every page, there are a couple handy ways to get ahold of Alphabyte:
Phone - 417.438.0843
E-Mail - support@alphabytecpu.com
In addition, for those either who need to get started right now or who can't be bothered with either e-mail or phone, there's a form - right here! (If you happen to be the person who can't be bothered with e-mail, you should probably get that fixed - 'cause that's how Alphabyte will respond to you, after you submit this)
