The Macintosh PowerBook Duo 2300c had a PowerPC 603e processor running at 100Mhz and a built in FPU.  The hard drive was available with either 750Mb or 1Gb of space.  The maximum RAM was 56Mb and it had a 9.5” active matrix LCD.  There were expansion slots for a modem and the dock but no included floppy or CD-ROM drive.


The first PowerBook to take advantage of the PowerPC chip, the PowerBook Duo 2300c was very fast and had a beautiful, clear screen.  Because it was in the “Duo” line, it was designed to act both as a desktop computer and as a portable.

  • Replica watches  are a favorite fashion choice with both men and women. What are Replica rolex Watches? They are imitations of one of any number of authentic luxury watch models. They appear to be genuine products although in reality they are manufactured very differently and at a much more affordable cost than those from luxury brands. There are several little-known Breitling replica facts, and one of the most important ones is that hardly anyone will be able to differentiate between a real watch and a replica
