This page is intended to contain links to my technical interests and projects.

Notes

SunOS 4.1.3U1 Binaries - Mar. 25 2010
SunOS 4.1.3U1 binaries of (mostly) recent open source projects built on a 4/630MP system.

90-92 GM ECM ROM Modification - Feb. 28 2010
Notes from disabling the VATS anti-theft system in the EPROM of the ECM from a 1992 5.0L swapped into a 1983 TransAm. Updated May 8 2010

Using Retr0bright - Feb. 22 2010
Notes, experiences, and cautions when using retr0bright to treat yellowed plastics.

68k Mac Video Settings - Jan. 23 2010
Notes from attempting to encode video for playback on older 68k Macs.

SE/30 Storage Benchmarks - Jan. 12 2010
Benchmarks of various storage devices from a 10k RPM SCSI disk to the lowest end unrated CompactFlash card.

ROM Archive - Jan. 1 2010
Backups of some difficult to find/replace ROMs. Everything here I've personally extracted the chips and read them on an EPROM burner.

Photo gallery scripts - Dec. 15 2009
A couple different people over the last few months have asked what photo gallery software I use in my gallery. Basically, it's some scripts I wrote in ~1999 when I got my first digital camera and the EXIF data was a novelty. Since then, the scripts have been updated to continue working and fix a few bugs, but the output format hasn't changed. I've made them available with some minimal documentation if anyone is interested.

AppleTalk Bridging Software - Dec. 13 2009
I've written a small AppleTalk Bridge to allow EtherTalk to be bridged across the internet through a central server to multiple client sites. Hopefully, this allows for playing the old AppleTalk games with people across the internet. So far, only limited testing has been done.

iDisk on a IIgs - Dec. 7 2009
I received an iDisk virtual Disk II controller for use with Apple II systems today. This is a writeup of my initial impressions.

Repairing a //c - Nov. 12 2009
A while ago I received an Apple //c as part of a larger lot of old machines I purchased. The //c had some problems, this documents the repair process.

Ethernet on a IIgs - Oct. 31 2009
My experiences using an Uthernet card in the IIgs with GS/OS and the Marinetti TCP/IP stack as well as Contiki on the IIgs.

Converting an AEC-6280 to work in a Mac - Oct. 22 2009
Modifying an AEC-6280 PATA IDE PCI card for use booting a PCI based PowerPC Mac.

Netbooting a IIgs - Oct. 20 2009
Setting up a IIgs to boot off a LocalTalk network served by a Performa 630CD using AppleShare.

Experiments with R-IDSC-E SCSI to IDE converter - Oct. 19 2009
Using an R-IDSC-E SCSI to IDE converter with the intent of using CF cards as primary bootable storage devices in older SCSI based machines (old macs, Suns, etc.)

Experiments in IDE-CF Adapters - Oct. 19 2009
Information on using IDE-CF adapters in various computers.

C64 Twitter Client - June 15 2009
A C64 Twitter client is now available, called Breadbox64. I had to create a twitter account just to give this thing a try, and it works great. I set it up on a physical c64 breadbox from 1982 with a 1541Ultimate (without an ethernet adapter unfortunately), an MMC64 with an RR-Net adapter. It has worked well for me, with one problem following a person with non-ASCII twits. It crashes trying to display them. Other than that, it works great.

Repairing Gameboy DMG LCD - June 12 2009
I have an old original gray GameBoy DMG laying around, but several columns of pixels on the sides of the screen were missing. Sometimes pressing on the LCD or the connector would temporarily make some columns reappear indicating it was a connection problem, but it would never stay fixed for very long. I found these instructions describing a more permanent repair. The summary is, disassemble the GameBoy, and take an old ~15W soldering iron with as blunt a tip as you can find, and run it (on & heated) over the connections of the dark cable going to the LCD. The goal here is to re-bond the solder on the connections without melting the connector its self. It worked great for me, I had maybe 10 missing columns on both sides, and now all are back on.

JP1 Remote Programming - June 10 2009
Programming some standard IR television remote controls using i2c to access their EEPROM.
