Subject: Apple //gs The Apple //gs could display an enhanced 320x200 video mode with up to 3200 colors (16 unique colors in each of the 200 scan lines). As far as I know, it was the only computer of that era capable of displaying more than 256 colors. The //gs' video port is a DB-15. Some design features from the unsuccessful Apple III lived on in the Apple IIGS, such as GS/OS borrowing elements from SOS (including, by way of ProDOS, the SOS file system), a unique keyboard feature for dual-speed arrow keys, and colorized ASCII text.
During the development of the greatest member of the Apple II family, the Apple IIgs, someone suggested to [Woz] that a sort of universal serial bus was needed for keyboards, mice, trackballs, and other desktop peripherals. [Woz] disappeared for a time and came back with something wonderful: a protocol that could be daisy-chained from keyboard to a graphics tablet to a mouse. Apple os in pc. This protocol was easily implemented on a cheap microcontroller, provided 500mA to the entire bus, and was used for everything from license dongles to modems.
The Apple Desktop Bus, or ADB, was a decade ahead of its time, and was a mainstay of the Mac platform until Apple had the courage to kill it off with the iMac. At that time, an industry popped up overnight for ADB to USB converters. Even today, there's a few mechanical keyboard aficionados installing Teensies in their favorite input devices to give them a USB port.

While plugging an old Apple keyboard into a modern computer is a noble pursuit — this post was written on an Apple M0116 keyboard with salmon Alps switches — sometimes you want to go the other way. Wouldn't it be cool to use a modern USB mouse and keyboard with an old Mac? That's what [anthon] thought, so he developed the ADB Busboy.

The ADB Busboy is the exact opposite of [tmk]'s ADB to USB converter firmware for the Teensy. Instead of turning an old ADB keyboard into a USB device, [anthon]'s ADB Busboy turns USB keyboards and mice into ADB devices. Now, every USB keyboard and mouse is compatible with almost every Macintosh ever made, save for the 128, 512, Mac Plus, PowerBook 150, and arguably a few other portable models.
Why would anyone want to do this? Apple disk space analyzer. Because it's neat. Check out the animated thing [anthon] made: Minecraft free for apple ipad.

There's no release for the ADB Busboy quite yet. [anthon] still needs to implement and test a few features, design a PCB, an enclosure, and hopefully sell these USB to ADB converters to some nerds who have far too many old computers in their basement. They're collector's items, get off my back.

[anthon] has a site up where he'll eventually announce this project's release. You can sign up for an email alert when that happens.
