Curiosity got the better of me and I took my brother's third party modified 
512K Mac and my Mac+ and exchanged the ROMs.

The result was that the 512K worked without an 800K internal drive!!

Here is a synopsis of observed differences and capabilities:

Third party modified 512K Mac with 400K internal and 800K external:

Doesn't recognize 800K discs formatted by Mac+ even with an 800K external 
drive that it would normally operate from.
Doesn't operate apple's 800K external drive.
 

512K Mac with new ROM's:

Can now read/write 800K discs formatted by Mac+ in an external 800K drive.
Can now operate and boot up from apple's 800K external drive.
The Mac can even boot up from the original internal 400K drive.
Boots up to desk top about 1/3 faster than old ROM Mac.
Opens, saves and quits MacWrite also about 1/3 faster than old ROM MAc.
Operates on new system file for Mac+

Well Apple how about it? Why don't you offer one more upgrade option for the 
people who helped make Mac what it is today!! 

$50.00 for the two new ROMs would be a nice alternative option which could 
help restore customers faith in APPLE!!
