Sinclair ZX Spectrum 48k - Suffolk Sciences School Expansion Board Test
I have a look at the bespoke expansion board which came with my ZX Spectrum Plus. Apologies for the rolling image (it was even worse on my LCD TV). The board was made by Suffolk Sciences in 1987 / 88 for use in schools within the county. In this case I believe the County Upper School in Bury St Edmunds.
Here is a link for a bit more information on the device from 2012:
