Where is the line ?

At the magic II chip, they said that some older gold PCB models can support the GS, using the Z connection, they said there is an under line in the sticker, where ? I assumed my chip "might" be this chip

As in V7 as distinct from V7.

I've wired it up on my non-underlined v7 and will try Ar2/v2 with codes this evening.

mmmmm, doesn't it sounds too risky, charlie ?
And I see in their website, that not only V7 chip that support the z connecttion, but also the R labelled chip for V4 non gap rom R type machine, see the installation jpg for detail, also for V5 R type machine, the chip were also labelled R
Can someone provide me with the pic of the R type chips that don't support the Z connection and the ones that do
