Differences Between TS2068, TC2068 and UK2086
As Timex Computer Corporation made the TS2068 hardware-incompatible with the ZX Spectrum, Timex of Portugal made some changes to the TC2068:
- Replaced the bus buffers with resistors like ZX Spectrum
- Changed the I/O connector to be ZX Spectrum compatible (not requiring the Zebra Twister board).
- Changed the cartridge slot top casing to accept bigger cartridges (ZX Spectrum emulator and Timeword cartridges will not fit in the TS2068 cartridge slot without modification of the slot)
- Instead of 15V, it uses 9V.
UniPolbrit also made some changes to the TC2068 for their Komputer 2086:
- Modified ROM
- Replaced a joystick port with a parallel printer interface

Famous quotes containing the words differences between and/or differences:
“What strikes many twin researchers now is not how much identical twins are alike, but rather how different they are, given the same genetic makeup....Multiples don’t walk around in lockstep, talking in unison, thinking identical thoughts. The bond for normal twins, whether they are identical or fraternal, is based on how they, as individuals who are keenly aware of the differences between them, learn to relate to one another.”
—Pamela Patrick Novotny (20th century)
