The ZX Spectrum SE is a proposal for an advanced Spectrum machine, based on the Timex TC 2048 and the ZX Spectrum 128, with Timex graphic modes, and 280K RAM., [144] made by Andrew Owen and Jarek Adamski in 2000. [144] A prototype was created, and this configuration is supported by different emulators. [145] [146] [147]
