The power supply of the computer is a heavy block which consists in a linear supply that outputs +5V, +12V, +24V, -5V and -12V. Its connector is a 12-pin molex structured in three columns and four rows. Other than the voltages, it also provides with a "power good" signal as posterior IBM computers would, such as the IBM PC. The first IBM PC prototype used the same connector and possibly the same pinout. Adapting an ATX supply to feed the main board is possible and relatively easy to do (actually, it is recommendable when testing the system in a bench). | The power supply of the computer is a heavy block which consists in a linear supply that outputs +5V, +12V, +24V, -5V and -12V.
