CoCo2 - Upgraded from 16K to 64K, one last question

So I got My 26-3134 Coco2 with 16k yesterday and of I course changed the Ram from the 4517's for 4164 and a jumper on J1 soldered in and voila 64K Coco2 but Still "Colour basic 1.2" with an empty ext basic ROM slot.
Now the Manual does stipulate that the Disk Extended Colour Basic 1.1 is a Part no. 8042364A (MC68A364) SCM92135P IC on IC13

I have a Coco 1 'for parts' with the "Disk Extended Colour Basic 1.1" ROM on it, part no. 8042364 (MCM68A364) SCM90522P IC on U28

Questions:
Is the Ext 1.1 identical in COCO 1 & 2? or should I burn a different 1.1 ROM for COCO2?

Attempt:
I have put it in, and it does boot in Disk Extended Colour Basic 1.1, and I have played a few games, and it loads "sailor man" just fine as well as others.
but I worry it may be just luck at this point.

I just want to make sure it is the right part that goes into this machine, any thoughts or suggestions?

I did confuse Disk Extended with Extended Basic in the previous information, I meant Extended Color Basic 1.0 versus 1.1

Well in the end, the Extended Basic from COCo 1 is v1.0 so I decided to grab 1.1 from the image and burn a 2764 and using a nifty adaptor (23xx to 27xx) I replaced the empty spot with a new Extended basic 1.1 solving the problem.
