It offered a maximum of 16MB of RAM (!), Serial and Centronic ports, disk interface and RGB monitor... On top of the Expansion Box Unit is the TS-2050 modem (300 baud). In fact the Timex Sinclair version never came out, but the original manufacturer, Westridge, released it when Timex disapeared. On top of the modem are two Microdrives (TS 2065) which also remained prototypes. At the left hand part is the TS 2080, a 80 columns 9 pin dot matrix printer (a redressed Mannsman Tally Spirit 80). Thanks to [Timex Computer World](http://members.fortunecity.com/johnnyred/home.html) for this picture. null title subtitle text image TIMEX SINCLAIR 2040 Printer The TS 2040 was the rebadged US version of the ZX Printer that could be connected to all of the Timex (and Sinclair ZX-QL) systems. It used the same thermal metallised paper rollers. LPRINT and LLIST commands redirected output to the printer. COPY did a screen dump. null title subtitle text image TIMEX SINCLAIR 2040 Box null title subtitle text image WESTRIDGE 2050 Modem The TS 2050 Telecommunications Modem was designed for Sinclair Research by Westridge Communications CIE. At the same period first deliveries of this modem should occur, Timex went out of the computer business. Westridge which then had a large stock of unsold modems decided to release them with the 'Westridge 2050' name. The modem was compatible with TS100, 1500 and 2068 models. A specific software was delivered for each model. It used an Intel 8251 USART chip with 300 baud capability through a direct connexion to a telephone socket. null title subtitle text image TIMEX FDD 3000 Floppy Disk Drive The Timex FDD 3000 was a Full Computer made by Timex Portugal. It could also be used as a Floppy Drive System for ZX Spectrum, TC 2048 and Clones, including the Timex 2068.\ It featured:\ Z80 Processor\ 64 KB RAM\ 2 x Serial Ports\ 2 x 3" floppy Disk Drives As it was a full computer it allowed to run CPM on it with Timex Computers acting as a terminal, or it could act as a Floppy drive system that kept the ZX Spectrum or compatible computer free because of the FDD own processor and RAM.\ On 'floppy drive mode' user ran TOS (Timex Operating system).

You can find them on my site, here: https://www.timexsinclair.com/computers/timex-sinclair-2068/ author date text JB (Ohio, USA) Monday 27th April 2020 Due to the time I have on my hands these days I decided to set up and start learning to program a TS 2068 like I did a TS 1000 back in the 1980''s. I used to write programs on it for everything I wanted to. But did not have the color that the 2068 has. I purchased a color TV and now I want to spend some time to learn to program it. I need some of the old magazines that were written on it in the 1980''s. Anyone out there have any to sell? author date text Yan (Brazil) Thursday 28th November 2019 It was my second computer and the one I missed more. If I could go back in time I never would have sold it. Currently I have a replica hanging on my office wall that I made myself and that I can look and touch when I feel that nostalgia for the good old times. :) author date text Norman Flessas (Maryland, USA) Friday 13rd September 2019 It was my second computer. My first was a Timex 1000. I modified the Commadore''s BASIC so I could run it''s programs on the Timex 1000. author date text Ariel (Argentina) Thursday 13rd September 2018 I was my firs computer on May 1984. Sold it in October 1986 for another computer (too 8 bits). Last year I came back to buy again the TS 2068. Today, I have three Timex Sinclair 2068 and the Printer TS-2040. author date text Clay Bowen (USA) Thursday 18th April 2013 This was also my first computer, and the first programming language I learned. One-touch BASIC. I remember having to store data on cassette tapes, and never being able to find those solid state programs (other than the ones it came with, CrazyBugs and something else) author date text RuiG (Portugal) Saturday 28th April 2012 Hello all. This was my first computer... if I can call it that. I should still have it at home, along with hundreds of games, joystick and such. How much would a collector pay for one of this? Thanks. author date text Marco G (Portugal) Saturday 21st April 2012 My cousin had one of this with a printer. The "emulator" was a cartridge accessible at the right. When the cover was lifted, you could actually swap cartridges and use word processing and other applications. A couple of games didn''t work, Spectrums came later, or at the same time, and then dominated the scene in Portugal. Compared to the 48k specys, this "clones" where better built and the keyboard was just excellent. The TV converter was also better than the 48k. author date text Kumbah2006 (USA / Boston area) Thursday 8th July 2010 For those looking for Spectrum "tapes" or other\ goodies, give "World of Spectrum" a spin. Ah, Crazybugs, cool game - and Androids was\ a definite challenge - the memories! :) WOS has a whole load of nice legal software\ for your Speccy or other (related) machine. Good luck! author date text Packard (Argentina) Thursday 12th October 2006 Yeah!! My first computer!!! I'm looking for the Androids or Crazybugs games.. for Spectrum emulators... Anybody has one of them??? Thanks!! author date text Petrvs (Argentina) Wednesday 16th June 2004 It is true that was largely sold in Argentina, much more than the Sinclair Spectrum. In fact until the CZ 2000 appeared software for Spectrum was denominated: "software for 2068 with emulator" /museum/timex-computers-tc-2048 /museum/timex-sinclair-1500 634 url date https://web.archive.org/web/20230605035710/http://www.old-computers.com/museum/computer.asp?c=634 2023-06-05

This is the American version of the Spectrum. It has an additional 8K extension ROM, cartridge port, two joystick ports and AY-3-8912 sound chip with extra Sinclair BASIC commands to support these devices (STICK, SOUND). It was packaged in a hard plastic silver case with nonstandard plastic keys.

The TS2068 is Timex's re-engineered 48K Spectrum. It was released in Fall 1983 just before Timex Computer Corp folded in Spring 1984. A rogue arm of Timex in Portugal continued to sell TC2068s (same as TS2068) and TC2048s (an improved Spectrum) until 1989. They, of course, were only allowed to sell in non-Sinclair controlled marketplaces.

Timex recognized that a 48K Spectrum would not continue being competitive in North America for long without changes being made. They developed two computers that were to be North America's debut of the Spectrum. One was called the TS2048 and the other the TS2068. The TS2048 was basically a 48K Spectrum w/ Kempston joystick and the advanced video modes of the TS2068. The TS2068 was a completely different computer with the Spectrum as its roots. Timex decided to only sell the TS2068. When sales over Christmas 1983 were disappointing, they pulled the plug. Timex of Portugal, no doubt encouraged by the Spectrum's popularity in Europe, continued to sell the TS2068 and offered the TS2048 as the TC2068 and TC2048 in parts of Europe, notably Portugal and Poland. When Timex pulled the plug, they dumped all their surplus TS2068s in Argentina.

As for Spectrum compatibilty: The tape I/O is the same so you can load Spectrum tape files. Spectrum BASIC is a subset of the TS2068's BASIC, so you can run Spectrum BASIC programs. The TS2068's ROM is different, though, so you can't run Spectrum m/c that makes use of the ROM. Without the aid of a Spectrum emulator, you can run about 7% of the Spectrum's commercially available software.

The Spectrum emulator is really a Spectrum ROM on cartridge (there are other forms) that is bankswitched into the lower 0-16K region. The top 48K region is filled with RAM. To the software this looks exactly the same as a 48K Spectrum. There are a few hardware reasons for incompatibilities but using an emulator, you can reach 97% compatibility.
