ZX Spectrum Plus 2
The ZX Spectrum +2 was the first model released by AMSTRAD after they bought out Sinclair. This is quite a capable machine and is considered to be largely analogous to the final Sinclair machine the ZX Spectrum 128k, known on the scene as a toastrack due to the big ugly heatsink on the right hand end of the case.
Like AMSTRAD's own CPC464 (I'd like one of those), the Plus 2 came with a cassette deck built in. For some reason it did not have a volume control like the AMSTRAD. I had one in the early nineties too. This is not it.
