The Macintosh Quadra series was introduced on October 1991. It was one of the most powerful desktop computers available at the time. It was the first Macintosh model to utilize the Motorola 68040 processor and at 25MHZ, made it powerful enough for scientific work and the most demanding graphic and CAD applications. It also was the first model to ship with the new Macintosh System 7 OS.
This model has become a desirable collectors model. It's form-factor ( along with its compact size and computing power ) is it's major attraction. I've found two on eBay that I purchased reasonably. One is heavily beat up, will not boot a startup disk and the screen image is heavily distorted.
The second one can be cleaned up nicely, but the hard drive causes a strange startup and reboots twice. I would like to replace it.
I'm hoping to salvage parts from the damaged unit and make the appropriate repairs.
