IBM System/34 (5340)

UvA Computer Museum catalogue nr 01.47

---

This computer from IBM's successful System/3x series (the predecessor of the AS/400 series) was introduced in 1977 and withdrawn from the market in 1979. Our machine has four 62PC hard disks and an 8" floppy disk station - in fact a sort of 'diskette jukebox'. There are three 5251 terminals. Unfortunately we don't have any manuals describing the details of the machine's hardware.
In the picture, the 5340 system unit is the rectangular box near the middle back of the picture. Its dimensions are 70x190x121 cm. It weighs more than 1000 kg.
