Description: RAMTAS clears all page-zero RAM, allocates the cassette and RS-232 buffers, sets pointers to the top and bottom of system RAM (RAM 0) and points the SYSTEM_VECTOR ($A00) to BASIC cold start ($4000). Finally, it sets a flag, DEJAVU ($A02), to indicate to other routines that system RAM has been initialized and that the SYSTEM_VECTOR is valid. It should be noted that the C128 RAMTAS routine does not in any way test RAM.
