- Microdigital TK 95 je brazilská verze počítače Sinclair ZX Spectrum vyráběný společností , následník počítače TK 90X. Vzhledově je podobný počítači . Počítač má mírně odlišnou ROM, byly provedené úpravy pro zvýšení kompatibility s počítači ZX Spectrum. Přidané příkazy TRACE a UDG ovšem zůstaly. Ne všechny periférie vyráběné pro ZX Spectrum byly kompatibilní s TK 95, Microdigital Eletrônica však vyráběla i několik svých periférií: světelné pero, interface RS-232 a modemy. Počítač nebyl na trhu příliš úspěšný, neboť v době jeho uvedení se již více prosazovaly počítače MSX. (cs)
- The TK95 microcomputer was the evolution of the TK90X made in the second half of the 1980s by Microdigital Eletronica, a company located at São Paulo, Brazil that manufactured some ZX81 clones before (TK82, TK82C, and TK85) and a ZX80 clone (TK80). The first version was launched in November 1986. The case was redesigned (copied from the Commodore Plus/4) and the keyboard was said to be "semi-professional" (according to the Brazilian manufacturer), with the some additional commands that did not exist in the ZX Spectrums (for characters defined by the user – UDG), and more compatibility with the original ZX Spectrum (some games did not run on the TK90X but ran well on the TK95). There was a version with 48 kilobytes of RAM. Inside, the same processor: Z80A running at 3.58 MHz, a ROM chip and some RAM chips (old dynamic rams 4116 and 4416). Microdigital did some reverse engineering to develop a chip with the functions of the original ULA from Sinclair/Ferranti. The modulator was tuned to VHF channel 3 and the TV system was PAL-M (60 Hz). The cassette interface ran at a faster speed than the Spectrum. Only two peripherals were released by Microdigital – a light pen interface and a parallel printer interface. Some other small companies in Brazil released clone versions of Interface 1 joysticks (Atari 2600-compatibles) and interfaces for 5¼" PC drives (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. (en)
- O TK95 foi o segundo e último clone (versão) brasileira do computador doméstico ZX Spectrum da empresa britânica Sinclair Research, fabricado no Brasil pela Microdigital Eletrônica a partir de meados de 1986. Utilizava o microprocessador Z-80A de 8 bits, em 3,58 MHz. A principal alteração do TK95 em relação ao modelo anterior TK90X estava em seu gabinete remodelado (na realidade uma cópia gritante do 'Commodore Plus/4'), com um teclado "semi-profissional" mais adequado para digitação do que o anterior, do tipo "chiclete". Foi feita uma pequena alteração na placa (que é exatamente a mesma placa e circuito do TK90X) que permitiu que alguns problemas de compatibilidade fossem resolvidos (a simples desconexão do diodo 'D1') [a única alteração da ROM foi a troca da tela de entrada de TK90X para TK. Então ele ficou conhecido como uma versão melhorada do TK90X pois ele teve uma compatibilidade aumentada de 90 a 95% para 98% desta maneira permitindo que mais jogos originais do ZX Spectrum executassem no equipamento. Porém, esta melhoria foi atribuída a uma ROM mais compatível. (pt)
