I've been blogging about my Replica 1 and some of the hardware and software I've been experimenting with on it. If interested, check it out at http://jefftranter.blogspot.ca/
Nice site, looks like your having fun with Vince's multi I/O board and your replica-1. You should go really old school and hand assemble your
Very nice work. I hope you keep it up with new an interesting projects. If your adventure program isn't too long I can see about adapting it to an 8k Apple-1/Mimeo.
Very nice, thanks for sharing this with us!!
I may want to leverage your 6522 experiments for an Apple II project that have going. I've been working on designing an "advanced" A2 prototyping card and wanted to have a series of "canned" learning exercises for a variety of skill levels. This card is going to support a 6522, among other things.
Since this is an A1 forum - who knows, I may do the same for the Apple 1 someday.
Feel free to use any of the info. I don't currently have an Apple II but I'd love to see an Apple 1 / Replica 1 prototyping board.
