TheTK 95microcomputer was a 1986ZX Spectrumclone byMicrodigital Eletrônica, a company located atSão Paulo,Brazil.[1][2][3][4] It was an evolution of theTK90X introduced the previous year.[5][6][7][8]
The case was redesigned (copied from theCommodore Plus/4[9][10]) and thekeyboard was said to be "semi-professional" (according to the Brazilian manufacturer),[11] with the addition of someSinclair BASIC commands that did not exist in theZX Spectrum's basic set (for user-defined characters – UDG), and better compatibility with the original ZX Spectrum (compared to the TK90X).[6]
Like the Spectrum, the machine had 48kilobytes of RAM. Inside, the same processor:Z80A running at 3.58 MHz,[5] a 16 KB ROM chip and some RAM chips (old dynamic rams 4116 and 4416).[5][6] Microdigital did some reverse engineering to develop a chip with the functions of the original ULA fromSinclair/Ferranti. The modulator was tuned toVHF channel 3 and the TV system wasPAL-M (60 Hz). Thecassette interface ran at a faster speed than the Spectrum.
Only two peripherals were released by Microdigital – alight pen interface and aparallel printer interface. Other companies in Brazil released clone versions of Interface 1 joysticks (Atari 2600-compatibles) and interfaces for 5¼"PCdrives (360 KB). The games had questionable legality being close to copies of the originals and the fans of the ZX Spectrum computer in Brazil were counted in tens of thousands.
notre constructeur brésilien va faire un effort et sortira dans la foulée le TK95 à l'allure d'un Commodore Plus/4.
