I built a small pilot run for testing, and have a few extra available.
So far, I have tested these on an Apple bus mouse card, //c, and //c+. The converter will support wired mice, or USB wireless mouse receivers. This is for quadrature mouse input functions only. It will *not* convert USB game devices to analog Apple compatible joysticks. It's for mice. Most basic USB HID mice will work.
When the next run is complete, I will be selling these online for $25 + shipping. If you would like one from the pilot run, I will make them available to AF account holders for $20 + shipping if you pay using Paypal friends and family. If you need to have paypal protection for goods and services, I'm happy to still offer them, but at the non-discounted rate of $25 each. Send me a PM if you have an interest.
