TRS 80 Eight Meg Disk System
by Bill Degnan - 12/20/2010 00:14
The TRS 80 Eight Meg Disk System was a monstrous hard drive, very fragile, and cost thousands of dollars in the early 1980's.
The TRS 80 Model II stands next to the Eight Meg drive for size comparison purposes.
The 20 pin data ports are only needed if you're attaching a 2nd, 3rd, 4th drive to the primary hard drive. Imagine having 4 hard drives running at once.
The original shipping box with catalog no. 26-4150
Here is the box for the secondary drive.
The secondary drive does not power up, the primary does not initialize. Needs some work.
