May 8, 2000 - XOOM's server hosting my homepage has been down for at least 2 weeks now. Luckily I created a mirror site on GeoCities last month ..... or maybe it was because I created this mirror site! ;^)

April 19, 2000 - Over time, I've received a number of e-mails saying that my homepage could not be accessed. This has been due to XOOM's servers being down. To avoid these problems, I've set up a mirror site at Yahoo!'s Geocities. I don't know if Geocities will be any better than XOOM, but hopefully they won't be both down at the same time! ;^)

What?

The AP5T Rev 3.1 is a motherboard made by AOpen. It is a 430TX board that officially supports up to the AMD K6 233 or Cyrix MX-PR266. It has a switching voltage regulator that can provide both linear and dual voltages. It supports clock multiplier of 1.5x to 5.5x, and bus frequency of 60MHz, 66MHz, 75MHz, and 83MHz. Here's the User Manual ap5t-3man.zip (412KB). It's in PDF format, so you'll need the Adobe Acrobat Free Reader.

Why?

After hacking my GA-586HX Rev 1.55 mobo, I wondered what other mobos could be modified in this way. Somehow it has become my new hobby to seek out old and obsolete mobos and try to breathe new life into them. ;^)
