Changes
/* Timex Sinclair model */
The TS 2068 was a more sophisticated computer, compared to its UK ancestor, the ZX Spectrum. It added a number of new features:
*an AY-3-8912 sound chip, as later used by Sinclair in the ZX Spectrum+ 128K 128 (but mapped to different I/O ports and thus incompatible)
*twin joystick ports
*a slightly better "chiclet keyboard" with plastic keycaps
