Ultimate ZX Spectrum BUS Expander + Adapters

Ultimate ZX Spectrum BUS Expander + Adapters comes with:

. 2x Vertical stand adapters;
. 2x Horizontal stand adapters;
. 12V 2.5A power supply.

The power supply is connected directly to the bus expander (not to the ZX Spectrum), it does not interfere with the PSU that is connected to the ZX spectrum, it provides extra 'juicy' (energy) to the peripherals without putting any stress on the ZX Spectrum. So it is the ideal expansion to connect multiple devices safely without overheating your computer. It comes with a 2.5A PSU and the board voltage regulator can deal with it without any problems.

Note: the expansion's PSU, CAN NOT be used directly on the ZX spectrum.
