The Color Classic is a very desirable model for vintage Macintosh enthusiasts and is a popular candidate for custom upgrades such as swapping the logic board with that of a Macintosh LC 575.
This model was likely more popular in the education market due to the compact size.
General Information
CPU
The Color Classic shipped with a Motorola 68030 processor clocked at 16MHz.
Memory
The Macintosh Color Classic computer comes with 4 MB of RAM built in. By installing two SIMMs, the user can expand the RAM up to a maximum of 10 MB. The Macintosh Color Classic accepts two standard 30-pin RAM SIMMs. The SIMMs must be the same size, either 1 MB, 2 MB, or 4 MB. The access time of the RAM must be 100 ns or less.
Video
The Macintosh Color Classic computer has a built-in color display with a 10-inch Trinitron monitor. Like the video interface in the Macintosh LC II model, the video interface in the Macintosh Color Classic uses separate VRAM for the screen buffer. The Macintosh Color Classic does not have an external video connector. The display screen in the Macintosh Color Classic displays the same amount of information as the Macintosh LC II with the Macintosh 12” RGB monitor: 512 by 384 pixels.
The Macintosh Color Classic comes with 256 KB of video RAM (VRAM) and a SIMM socket for expanding the VRAM to a total of 512 KB. The VRAM expansion SIMM is the same 68-pin SIMM used with the Macintosh Quadra computers. The basic 256 KB video RAM provides up to 8 bits per pixel; the screen displays 256 colors, selectable from a range of 16 million. With 512 KB of VRAM, the Macintosh Color Classic computer can display up to 16 bits per pixel, which provides 32,768 colors. If the VRAM SIMM has been installed, the user can set the display to 16 bits per pixel by opening the Monitors control panel and choosing Thousands.
Expansion
Processor-direct slot (PDS) for hardware expansion; compatible with the PDS on the Macintosh LC II.
The PDS expansion card for the Macintosh Color Classic computer is approximately 3 inches by 5 inches and plugs into a 96-pin connector on the main logic board. An opening in the case accepts a 15-pin D-type connector for external I/O to and from the card.
Troubleshooting/Repair
Capacitor replacement
The SMD capacitors on the logic board will most likely have already started leaking electrolyte out the bottom, and failing to replace them in a timely manner will result in further leakage with possible damage to nearby components. See below list of capacitors to replace:
- 6 x 47uf 16V
- 2 x 100uf 6.3V
- 1 x 10uf 16V
Notes
- When the Apple IIe Card for Macintosh is installed in the expansion slot, the Macintosh Color Classic uses a timing signal from the card to generate a video display with the necessary 560-pixel horizontal timing.
- The Macintosh Color Classic computer requires System 7.1 or later system software.
