IBM storage disk used in the 70s and 80s. This stack of eight 35 cm disks weighs more than 10 Kg, and can store 320 Megabytes or 34 minutes of music

MFM Hard Drive. (Type of hard disk used in XT computers)

Small flexible plastic disk covered with a magnetic substance used to record data and computer programs. They can normally contain 1.44 MB of data and they are convenient for moving small amounts of data as they are transportable.

It's a 48 x 1 Gbit/s port switch with 10 Gbit/s optical uplink connection.

In the late 70s the larger IBM computers were water cooled. Amdahl, an IBM competitor, invented an air cooling technology for it's computers. His company worked hard, developing a computer that was faster and less expensive than the IBM System/360 mainframe computer systems. This object contains an actual Amdahl series 470 computer logic chip with an air cooling device mounted on top. The package leads and cooling tower are gold-plated.

Each module contained 8 circuit cards for a total of about 300-500 uncovered transistors packaged with face plates so the Freon plates wouldn't touch the circuits. (cooling plates that surrounded each module).

This processor relies on two key points: maximum performance and minimum heat output. 4M Cache ; frequency 2.40 GHz ; 1066 MHz FSB

8-inch floppy diskettes of the 70’s and 80’s.

It's a timing disc from the CDC 3300 computer. This computer was released in 1965. Moreover CDC means Control Data Corporation.
