: ''This article is about the Timex Computer 2048 (TC 2048). For the similarly named but different ZX Spectrum-variant prototype intended for sale in North America, see Timex Sinclair 2048 (TS 2048).'' The TC 2048 or Timex Computer 2048 is a computer created by "Timex of Portugal, Lda", a branch of Timex Corporation. It was highly compatible with the Sinclair ZX Spectrum computer, although differences in the ROM prevented 100% compatibility. Timex Portugal sold the TC 2048 in Portugal and Poland, where it was very successful. Also, a NTSC version was sold in Chile. This computer forms the basis of an improved Spectrum-compatible machine, the Spectrum SE. ==Technical specifications== CPU *Zilog Z80A @ 3.50 MHz ROM * 16 KB RAM * 48 KB Display * Improved ULA offering additional screen modes: * * Text: 32×24 characters (8×8 pixels, rendered in graphics mode) * * Graphics: 256×192 pixels, 15 colours (two simultaneous colours - "attributes" - per 8×8 pixels, causing attribute clash) * * Extended Color: 256×192 pixels, 15 colors with colour resolution of 32×192 (two simultaneous colours - "attributes" - per 1×8 pixels) * * Dual Screen: (two 256×192 pixels screens can be placed in memory) * * A monochrome 512×192 mode Sound * Beeper (1 channel, 10 octaves and 10+ semitones via internal speaker) (separate purchase the Joystick/Sound Unit was available to enhance sound and provide a joystick port. ) I/O *Z80 bus in/out *Tape audio in/out for external cassette tape storage *RF television out *Composite video monitor out *Kempston Joystick input Storage *External cassette tape recorder *1–8 external ZX Microdrives (using ZX Interface 1) *Timex FDD (Floppy Disk Drive System Power Supply, Controller and Disk Drive in separate cases. 16K RAM, Timex Operating System (TOS)) *Timex FDD3000 (Enhanced version (all in one case) of the Timex FDD but upgraded to 64K RAM & TOS with two Hitachi 3″ disk drives) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Timex Computer 2048」の詳細全文を読む スポンサード リンク
