I can confirm this - I have both the 7000 and 7500 manuals in front of me. Use the fx-7000g manual with confidence. The differences are minor and mostly related to the capacities of the machines, e.g. 7000: max 52 memories, 7500: max 526 memories.
Here is one added feature of the 7500g, transcribed from the manual. This appears at the end of section 3-2. (My 7000g doesn't have batteries in it at the moment; perhaps this exists as an easter egg in the earlier model?)
* Instant factor function
The instant factor function can be used to quickly magnify the size of a graph by 2n or reduce it by 1/2n. The change in size is centered at the pointer when it is displayed, and at the center of the graph when the pointer is not displayed.
(Shift)(×) ... 2X magnification in both x and y directions. Pressing (Shift)(×) again magnifies by 22 or 4X, and a third press magnifies by 23 or 8X.
(Shift)(÷) ... 1/2 reduction in both x and y directions. Pressing (Shift)(÷) again reduces by 1/22 or 1/4, and a third press reduces by 1/23 or 1/8.
Since range contents are switched to their inverse proportions, the graphic display is cleared each time the instant factor function is executed.
The following input ranges (p201) are clarified in the 7500g manual:
log x, ln x: 10^-99 <= x < 10^100
x^y: When x<0, y=n, 1/2n + 1 (n is an integer)
x=0 -> y>0
When x>0, -10^100< y log x < 100
Pol(x,y): sqrt(x^2+y^2) < 10^100
With the exception of references to amounts of memory available or free in the text or on sample displays (422 bytes max on the 7000G, 4006 bytes max on the 7500G), some keycap graphics, and some of the physical specs in the back, I could detect no other differences.
