Sinclair Spectrum collection

It has been some time since I last picked up some new items for the collection. After an email regarding a Sinclair Spectrum set I am please to say that there are now some very interesting items included in my most recent addition. I have not seen nor worked with the Spectrum modem or what appears to be a parallel port interface. The power supply is damaged so will need replacing or repair. Hopefully I will get time to test everything in the near future and add each item to the website. Also included is a Sinclair calculator which I have not seen in person before. Here are some overall pics.
