The end of the Classic line in the North American market, the Color Classic (a.k.a. Performa 250) shared the motherboard design of the LC II – equally limited in RAM expansion, constricted by a 16-bit data bus, and able to use 16-bit PDS cards designed for the LC. The only significant difference is the presence of a socket for adding a 68882 math coprocessor.

The Color Classic’s claim to fame is a tiny, remarkably crisp 10″ (9″ viewable) 512 x 384 pixel color monitor – and Apple IIe emulation using a PDS card. (The 512 x 384 pixel display matched the format of the 12″ monitor designed for the LC and LC II, which accepted the same Apple II card.)

“In many ways, the Color Classic is the compact Mac everyone’s been waiting for since, well, since 1984.” (MacUser, April 1993)

Nice as it was to have color, the pedestrian performance due to the 16-bit motherboard earns the Color Classic the Compromised Mac label. Yet despite poky performance, the Color Classic is a perennial favorite: it’s cute, and with some surgery it can support 640 x 480 on the internal display. (The Colour Classic II, with a 33 MHz CPU on a 32-bit bus and room for 36 MB of RAM, is what the Color Classic should have been. Since the CCII and Performa/LC 550 share the same motherboard, you can easily upgrade your Color Classic to Colour Classic II levels with a 550 motherboard.)

The Color Classic had an internal microphone above the screen and a readily accessible motherboard: just open the rear panel and slide out the board for upgrades. You can control volume and contrast using controls on the front of the computer – no need to open control panels.

Shield Color Mac Os X

As of Mac OS X Lion 10.7, Terminal allows customizing the ANSI colors, so using SIMBL or other extensions is no longer necessary. It also supports 256 colors. – Chris Page Sep 4 '11 at 8:59.
Mac OS 10.7 – Current. Hold down Command (⌘)-R immediately after turning on or restarting your Mac until you see the screen to the right. Select Disk Utility and click continue. Select your computer’s hard disk volume from the left pane, then click the First Aid tab. Click Repair Disk. When the repair is finished, restart your Mac from.

Unlike other compact Macs, the Color Classic can be shut down with the power key on the keyboard. The Color Classic is also turned on with the keyboard power key.

The Color Classic was the first Mac with a built-in color monitor, although the unusual 512 x 384 pixel format size meant many games would not run properly, if at all. However, it is possible to hack the circuitry to support 640 x 480 or add a video card that allows use of a larger external monitor. (This was the first compact Mac since the SE/30 to offer an expansion slot.)

Resolve issue where flashing color band would be visible when viewing video in portrait mode. Resolves corruption issue observed at the bottom of the screen when upscaling content to 4K displays. Network/Storage: Fixes bug where password for sharing folders on SHIELD.
