See Chapter 6. And, yes, apparently 48 MB was the maximum main storage size for the B50 (no explanation as to why.)

Reminds me of my old TRS-80 Model I, which had an absolute maximum of 48k (not M!). Out of the 64k address space of a Zilog Z80, 12k was the BASIC ROM, 1k was static RAM for the screen buffer, and the rest was memory-mapped I/O.
