Combining 2x 16K ROM into 1x 32K ROM


Recommended Posts

New at this, so would be a basic question, hehe.

I want to burn data from 2x 2716 (9316) into one 2732. How does the Chip Select work?.

Does it need CS?

Does it rely just on the memory address?.

Nothing explanatory on the Web other than the physics of it.

This is for an early CPU, Cinematronics.

I'm not sure what type of programmer you are using but with mine i just select the chip as a2732 ,then load the first file onto the buffer , then set the buffer to a positive offset of 800(that's where the first file finishes) and then load the second file.

Then burn the image onto a 2732

Hope that helps

Oh ok, I understand now. Thanks Ken, much appreciated.

 

I have just found that there are no jumpers but there are modifications to traces etc. to achieve this.

The same can be done with cmd prompt

type rom1.rom>>newrom.rom

type rom2.rom>>newrom.rom

 

the result is the first rom added to a new rom file, then the second rom appended to the newly created rom
