The Macintosh Performa 5260CD is an all-in-one personal computer manufactured by Apple Computer, Inc., introduced on April 22, 1996.[1] It features a 100 MHz PowerPC 603e processor in the same all-in-one chassis as its predecessor, the Performa 5200CD.
The Performa 5260 series replaced the PowerPC 603 CPU with the improved 603e. The system shares its logic board and form factor with the education-market Power Macintosh 5260/100 and various regional variants sold under different model numbers.[2]
Model Variants
[edit | edit source]The Performa 5260 family includes several regional and speed variants:
| Model | CPU Speed | Hard Drive | CD-ROM | Introduction | Region |
|---|---|---|---|---|---|
| Performa 5260CD | 100 MHz | 800 MB or 1.2 GB | 4X | April 22, 1996 | Worldwide |
| Performa 5270CD | 100 MHz | 1.2 GB | 4X | April 22, 1996 | Asia, Europe |
| Performa 5280 | 120 MHz | 1.2 GB | 8X | November 12, 1996 | Japan |
The Performa 5270CD is identical to the 5260CD with a different model designation for Asian and European markets. The Performa 5280 is a later variant with a faster 120 MHz CPU and 8X CD-ROM drive, sold exclusively in Japan.
Architecture and Processor
[edit | edit source]The Performa 5260CD uses the PowerPC 603e processor running at 100 MHz with a 40 MHz system bus.[3] The 603e is a 32-bit processor with a 64-bit data path and includes an integrated floating-point unit.
Cache Configuration
[edit | edit source]- L1 Cache: 32 KB (16 KB instruction + 16 KB data)
- L2 Cache: 256 KB (optional expansion slot)
