My comment was directed toward your reference to the Tarbell
controller, not the NS.
The single-density controller does indeed have 256
byte of ROM (in three chips!)
The double-density one has 512 bytes of ROM.
A question crops up: why? What's the point--you need only enough to
load a sngle sector. Was the NS controller so badly implemented
that it required that much code to read a single sector?
