AppleTi and F18A at KansasFest

Years ago, I outlined interfacing the F18A, a TMS9918A Video Display Processor (VDP) clone with VGA output, to the Apple II.  I never followed through, but somebody on the AtariAge forum recently completed a design and released a PCB.  The “AppleTi” board is a functional clone of the E-Z Color Graphics Interface.  The AppleTi board …

For all media, the original intent was “symmetric authoring and consuming”. So much of our culture is about consumption.  In some ways, …

MicroKIM

The KIM-1 was an early single-board computer that helped introduce the “masses” to micro-computing with the MOS 6502 processor.  MOS built and distributed the KIM-1, presumably to help sell more microprocessors.  Briel Computing has recreated the KIM-1 with the MicroKIM.  I built a MicroKIM at KansasFest last summer.  The kit was a blast to build.  …

MiniRoboMind Board Support Package Release

I’m pleased to announce the release of my board support package for the MiniRoboMind (MRM).  The MRM is a single-board computer based on the 68332 micro-controller and is the heart of BlueBot.  I found software support for the MRM to be scattered and incomplete, so I wrote my own with inspiration from existing software. I’ve …

HackFest 2012

HackFest is both a tradition at KansasFest and for me personally.  I find that as I attend more KansasFests, my HackFest projects get smaller simply because I’ve discovered all the fantastic off-schedule activities.  At my first KansasFest, I’d retire to my room between sessions and after meals.  But, some of the best discussions and discoveries …
