# Informative Letter from Doug Smith, Timex’ Director of Product/Market Planning

Dear Timex Sinclair 2068 Owner:

Thank you for your recent request for technical information on the 2068 computer. Available information is as follows.

A large size schematic diagram of the T/S 2068 may be purchased for $2.50 (postage included) from the Timex facility in Little Rock, Arkansas (address listed below). The schematic will be available starting April 1, 1984.

A comprehensive [Technical Manual](http://localhost/book/timex-2068-technical-manual/) will also be available from Little Rock, starting May 1, 1984. The manual is quite lengthy and will be priced at $25.00 (postage included). It includes a reduced size schematic diagram. The Manual includes an updated and corrected version of all of the material which previously had been made available as the “[Timex Sinclair 2000 Third Party Software Guide](http://localhost/document/timex-sinclair-2000-third-party-software-guide/)” It also contains additional information, some of which has been published as Technical Notes or Bulletins. This Manual includes ALL technical information which is available from Timex for the T/S 2068. Subjects covered include memory, bank switching, block diagram, 1/0 facilities, 1/0 port layout map, interface with external devices, connector specifications, character set, system software, commands available on the 2068 but not on the the ZX Spectrum, advanced video modes, connection of RGB Monitor and other information. The address for both the schematic and Technical Manual is as follows:

Timex Materials Sales Division  
P.O. Box 1378  
Little Rock, Arkansas 72203

The information described above is the ONLY technical information that is available for the T/S 2068 computer. No information is available for products which have not yet been shipped, including the Modem, System Interface Unit, 80-Column Printer, or Microdrives. Accessories and peripherals marketed for the ZX Spectrum will not, in general, directly interconnect with the T/S 2068. We have no information on modifications required for such an interconnection.

Thank you for your continued interest in the T/S 2068.
