Location for Machine Code

When you turn on your TS2068 computer, POKE 23730,255 and ENTER. Then press NEW and ENTER. This will put RAMTOP at address 65535 which is as high as possible. Then input the following:

9999 PRINT FREE-276

When you GOTO 9999 the screen will display 38534, which is the number of bytes actually available in RAM for your program. This not only gives you another 168 bytes of RAM for BASIC programming, but also provides a protected area of 276 bytes between addresses 65260 and 65535 for machine-code. The computer will not overwrite that area because when the size of your program reaches 65259, the bottom of the screen shows “OUT OF MEMORY.” You can place your machine code in this space and save to tape using the command

SAVE " " CODE 65260,276

This little trick should not be used if you intend to use the UDG (User Defined Graphics) mode.
