TIMEX BASIC 64
Sinclair basic extension

Timex BASIC 64 was developed by Timex of Portugal and it is an extension of the Sinclair Basic to work with the TC2048 and TC2068 high-resolution mode. BASIC 64 has four versions, one for TC2048, one for TC2068, and variations of both when the FDD system is connected so the user can auto-boot BASIC 64 by pressing the reset button on the TI.

BASIC 64 Tape has a Demo of the capabilities of BASIC 64.

With BASIC 64 you can have 64, 85 or 128 columns of text and high-resolution graphics (512×192). New system variables are created, and the area of the Basic program is moved to the front of the second display file, so it cannot corrupt the screen.
