Sony AC-HB2P

The Sony AC-HB2P is an external power supply (PSU), that was supplied with the Sony HB-20P MSX computer in Spain.

This AC adapter is very similar to the Sony AC-HB1 series of power supplies, in that it has the same output voltages, and connector and they are therefore compatible.

If the power supply is missing, it can be difficult to source a replacement, as it not only uses an unusual connector, but it also supplies two different voltages of which one is AC and the other DC.

While this adapter may seem similar to the Sony AC-HB3, the connector and output voltages are NOT the same, and they cannot be used as substitutes
