==== Sparrow 48K ====
The '''Sparrow 48K''' is the first modern clone of the ZX Spectrum designed to replace the original motherboard in standard and Spectrum+ case.<ref>{{Cite web|url=https://zxsparrow.com/speccy_hw/Sparrow48K/index_eng.html|title=Sparrow 48K}}</ref> Production commenced in 2013. In addition to the use of the original ULA chip, this clone was heavily modernised, replacing part of the larger glue logic with one CPLD chip, the entire main memory with one SRAM chip, and all 8 video memory chips with a second SRAM. The TV modulator has been dropped in favour of a video signal, and the [[Power supply unit (computer)|PSU]] was changed and improved. The Sparrow also offers a larger ROM, which can be increased by 16 KB via a switch or a jumper.<ref>{{Cite web|url=https://zxsparrow.com/speccy_hw/Sparrow48K/index_eng.html|title=Sparrow 48K|website=zxsparrow.com}}</ref> The successor is the Sparrow SX, with software ROM switching  and RTC.
