This device was a development of the K5501. It looked very similiar to its predecessor design model and could only be differentiated by two additional LEDs.

Depending on the number of installed magnetic disks, the disk space varied. There were models with 2,3 and 4 magnetic discs, which has 68, 110 or 160MB of capacity. In the end, even for the largest model remained only 124MB usable capacity after formatting.

Until the closing of the manufacturer's works in 1992, the disk type was still produced. Today there are only six known copies in the world.
