The MB03+ is a small hobby project

[MB03+Team]

The MB03+ interface is designed and built to work best with older electronic circuits and different versions of ZX Spectrums. It has implemented many extensions to work together and not interfere with each other - so it should work smoothly with your ZX Spectrum. MB03+ is manufactured and tested with the utmost care, however, as this is a hobby (one-man) project and units are made in small series, it is not possible to provide all support and guarantee typical for commercial products.

If there are any problems with your MB03+ unit, we will try to find out and give you advice on how to identify the source of problems with your computer and how to fix it. In the case of persistent problems, the author of the MB03+ warrants that within the first two weeks after receiving the shipment, you may send your MB03+ back and you will be fully refunded.

Please read the Start Guide manual, follow recommendations and use your MB03+ with computers and devices compatible with the types listed in this manual!

The MB03+ does not require external power and cannot overload your ZX Spectrum. However, it is recommended to use a carefully maintained, refurbished or brand new high-quality power supply for your ZX Spectrum.
