Wayne, you are out by a factor of two. The original IIc ROM is a 23128 (16KB) while the later versions use a 23256 (32KB).
That makes sense. Somehow I'd had the idea that the orinal ROM was an 8k without actually thinking about it. Now that I do I can see that it'd have to be at least a 16k ROM otherwise the code couldn't possibly fit. Thanks for pointing that out, it might remind me to look at things more closely Wayne
