Design- Individual panels to perform

different functions- More than 30 tons- 1800 square feet- 150 kW of power- Numbers passed in between

panels in order to achieve high speed calculating

Components- 17468 vacuum tubes- 7200 crystal diodes

- 1500 relays- 70000 resistors

- 10000 capacitors- Around 5 million soldered joints

- Could compute up to 357 10 digit multiplication equations per second

- Several tubes burnt out per day and needed replacement- Longest time without failure was close to 5 days
