That's great.

 

Today I received a CoCo2 computer... fortunately the keyboard works just fine.. but then again these membranes are not good... will this keyboard be compatible with the CoCo 2 also?

Yes will work and fit with coco2 ( as shown above )

The extra keys can be addressed from basic even

Well... I am new to CoCos.. I have not been able to test the CoCo 3's because of the keyboard. Now on the Coco 2... I have a Diagnostics cart...everything passed with flying colors.

 

How can I check on all these items?

It will say extended color basic on boot if you have it..

As for lowercase

If you hit shift zero you will normally get inverse  text

So if you type

POKE 359,57.    (ENTER)

POKE 65314,16. (ENTER)

now try shift zero 

If you have the ti video chip you will see true lowercase letters while typing

The computer wont understand it though 

So commands like cls wont work unless uppercase. But you can use it in text..

Earlier today a Coco 1 computer was delivered at my door. Initial testing shows a couple of non-worklng keys. Stilll need to deep clean it. Wondering if these keyboards will fit CoCo 1s too?

Trying to get it to the original color... asked in the CoCo maillist and got a response about Mercedes-Benz CLK Class 744 Brilliant Silver. I am contacting a local paint company to get a couple of cans of this color... is this the correct one?
