Power Macintosh 6400 (Performa 6400)
PPC603ev processor at 200MHz. 8MB RAM on board. 30gb hard drive. CD drive.
Everything works fine. I did a fresh install of Mac OS 7.6.1 from the CD drive.
The only work that has been done to the computer aside from a little bit of cleaning is that I have replaced the battery pack with a CR2032 holder (less likely to leak).
It is dirty, it is starting to yellow, there is some cracked plastic, and the comm slot cover is missing.
