The ULA chip, described by the ZX81 manual as the "dogsbody" of the system, has a number of key functions that competing computers share between multiple chips and integrated circuits. These comprise the following: [9] Synchronising the screen display; Generating a 6.5 MHz clock, from which a 3.25 MHz clock is derived for the processor;
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]
The device supports all the Timex Sinclair machines, [10] coming with a cassette containing modem control software for T/S 1000 and T/S 1500 on side A and for T/S 2068 on side B. [11] It was based on the Intel 8251 USART chip and very slow (300 bit/s).
