Nowadays clones and interfaces are being created that can run demos for various ZX Spectrum hardware accessories and clones, such as the ZX-UNO, the ZX Spectrum Next and the MB03+ Ultimate interface. The eLeMeNt ZX computer is specially designed to support enhancements used by demomakers, that includes 3 memory models of the Pentagon and the ...
The ZX Interface 1, launched in 1983, was a peripheral from Sinclair Research for its ZX Spectrum home computer. Originally intended as a local area network interface for use in school classrooms, it was revised before launch to also act as the controller for up to eight ZX Microdrive high-speed tape-loop cartridge drives.
The Profi or ZX-Profi is a Soviet ZX Spectrum clone developed in 1991 in Moscow by Kondor and Kramis. [ 112 ] [ 113 ] [ 72 ] It features a 7 MHz Zilog Z80 CPU, up to 1024 KB RAM, 64 KB ROM, AY8910 sound chip, Beta 128 disk interface, IDE interface, and 512 x 240 multi-colour (i.e. two possible colours per 8 x 1 block) graphics mode for CP/M ...
ZX Spectrum outputs one video line in exactly 224 CPU clock cycles, where the CPU clock rate equals 3.5 MHz. This exactly matches the PAL standard 64 μs line time. However, the ZX Spectrum produces only 312 lines to form one display frame, while the PAL standard recommends 312.5 lines. As a consequence, the frame rate of the ZX Spectrum is ...
The ZX Spectrum Next is an 8-bit home computer, initially released in 2017, which is compatible with software and hardware for the 1982 ZX Spectrum. It also has enhanced capabilities. [1] [2] It is intended to appeal to retrocomputing enthusiasts and to "encourage a new generation of bedroom coders", according to project member Jim Bagley. [3]
The 8-bit RGB palettes (also known as 3-3-2 bit RGB) use 3 bits for each of the red and green color components, and 2 bits for the blue component, due to the lesser sensitivity of the common human eye to this primary color. This results in an 8×8×4 = 256-color palette as follows:
Much of the East Coast was in for a polar reprieve. But that warm-up comes with a price: foggy, wet weather, and in some cases a full-blown soaker.
The use of a Spartan FPGA allows the system to not only re-implement the ZX Spectrum, but many other 8-bit computers and games consoles. [161] The device also runs modern open FPGA machines such as the Chloe 280SE. [162] The Uno was successfully crowdfunded in 2016 and the first boards went on sale the same year. [163]
