query: What limitations did the 8080 processor impose on the memory available for programs and data in MBASIC?
answer: The 8080 processor's 64 kilobyte address space was shared by program text, variables, disk buffers, and the CP/M operating system.  Even with 64KB of RAM, often less than 32KB was available for programs and data when MBASIC initially started.
