Re: 16 out of 30. Well, we're half way there Message #2 Posted by Eric Smith on 14 Apr 2012, 2:27 a.m., in response to message #1 by Matt Agajanian
For continuous memory they needed CMOS RAM chips. Those held only 16 registers each. They had PMOS chips combined 1Kx10 of ROM with 16 data registers, at a lower cost than the CMOS RAM-only chip. Had they made all of the RAM from CMOS, they would have needed more chips at significantly higher cost, and it would have been difficult to fit all of the chips into the available space.
