So I (finally) started drawing schematics tonight, its been one big delay after another in osgeld Labs, some of it unavoidable some of it very avoidable. Since that’s the way its working I would like to announce 180$ preorders (kidding guys) no I would like to announce a basic starting point schematic and firmware for the hardware tinkerers.
First a rant on KiCad. KiCad is a open source EDA (electronics design automation package) you draw a schematic, assign footprints, make a pcb, ship it off and get back a printed circuit board. Though I have been using it for years, tonight I just about lost it… every simple durn thing turned into a MAJOR pain in the BUTT! Thats it, I am done, when peoples software just gets more and more broken over time, I dont have time to screw with it anymore, its not worth the stress, and this downhill slide has been going on for a long while it seems.
After taking 3 hours to do something that would have taken an hour min in Altium (another EDA that cost thousands of dollars, we use at my work) I was trying to export the schematic to PDF, SVG, any darn thing where it would loose half my work. So in a nutshell screw that, and for now you will have to deal with a crappy screenshot.
Word of warning, I have not actually made hardware off of this schematic… it should be correct (I kind of do this for a living), but I don’t guarantee it. Its also very basic hardware and there will be more things added into it in the future, mostly basic things like an LED, a switch, maybe a couple jumpers, but a biggie is a Real Time Clock … if I ever settle on one.
Software is also in a very basic state. this is not my current build, but its one that works as a VSDRIVE host, and nothing more. Since this is all in a very basic state, and not at all close to what I consider ready.
I will not be held responsible if you hook it up and blow something up… so dont save your tax forms on it, and accept personal risk to your hardware if you tinker with it.

To compile software you need Arduino 1.01 (should work with 1.02 and 1.03 I will check in the near future) software and fatSDlib library installed in the libraries folder of wherever you install arduino.
you also need the apple II software, from the last 2-3 revisions of ADTpro
