The ZX Spectrum +3 was released on the 16th of May 1987. It is a significant redesign from the original [[ZX Spectrum 128K|"Toastrack" 128K]] and [[ZX Spectrum +2|Grey +2]] models, with additional memory paging capabilities to support [[CP/M]] and additional ROM containing the [[+3DOS]] disc operating system code. | The ZX Spectrum +3 was released on the 16th of May 1987.

The "Black +2" appeared soon after. This computer can be one of two machines, a +2A or the later +2B. The lower case moulding carries one of these two designations, however this has been found not to be an accurate indication of which model the computer is as the majority of machines carrying the +2A label actually contain a +2B motherboard. | The "Black +2" appeared soon after.
