VCF East 2011

Saturday, February 26th, 2011

Well, the family will have to hold down the fort for a weekend in May while I exhibit at VCF East 2011. If you want to see my stuff in person without buying it, here is your chance.

Brain Board PCBs shipped from vendor

Tuesday, February 22nd, 2011

Should have them in about a week. I’ll immediately do a quick checkout to make sure they behave like my proto and get Beta started.

If everything goes smoothly I’ll be shipping by end of March.

I’m really excited about this project, it’s really a wicked neat little personality board for your Apple II – kind of like giving it a lobotomy. I’ll be posting more details about the design once I get closer to shipping.

Mind Blowing Update #2

less blur

After much delay mostly do to distractions with other projects, the software is done with no known open issues and the prototype board is working great. The production PCBs are order and will arrive in about 5 weeks. I thought I could get quick turn PCBs made, but this wasn’t to be, hence the long lead time. Here is timeline for future announcements and release.

1) I hope to have time to put together a video podcast showing a demo of prototype, so everyone can finally see what this is about. I hope to be able to post this sometime next weekend. I’ll also announce target pricing at that time.

2) The rest of the parts for the first production run will be ordered.

3) After taking a day or two to assemble and check one of the production boards for myself, I have two Beta testers lined up and they will get a few weeks to check out the board.

4) A web page will be created with downloadable instruction manual.

5) Assuming all goes well, I hope to be shipping in about 8 weeks.
