Personal Info

I married Sarah Lyons on May 22, 1999, and we moved into a house in San Jose the first week of July the same year.

Since 1989 I've worked for Apple Computer, Inc. From 1989 to 1999 I lived in Cupertino, California. Before that, I lived in North Liberty, Iowa, went to Penn Elementary, Northwest Junior High, and West High, all in the Iowa City Community School District (ICCSD), and attended the University of Iowa in Iowa City. I graduated in December 1988 from the computer science department.

Interesting stuff I bought:

I bought a house in June, 1999 and have added phone jacks and Cat 5 network jacks both upstairs and downstairs. Home Tech's web pages and staff were very helpful. I had to crawl under the house as well as in the attic, open up drywall, and buy a 16"-long drill bit. I didn't do a detailed write-up, but Andy McFadden wrote about his wiring project.

Apple II software I wrote

Nifty List, Davex, and DIcEd used to be Shareware. They are now freeware, and someday I'll package these up and donate them to the Lost Classics project. (If you care, remind me.)

February and March 2002: I helped Rich Dreher with the firmware & software for his CFFA board: Compact Flash for Apple II. — The firmware presents the storage to the Apple II as one or more block devices, using the ProDOS and SmartPort conventions.

2006: I wrote most of the firmware for Rich Dreher's CFFA1 board for the Apple 1 and replicas. — This was a different sort of project. Instead of presenting the storage to a host operating system as a block device, it's a menu system (and small API) that implements simple file operations on ProDOS-formatted volumes. It supports a single level of subdirectories and reads/writes entire files at a time.

A great Apple II resource is A2Central.
