[Coco] First experiences with my DE1

[Bill Pierce]

I would think that the decb rom would have to be at least in a position "reletive" to the original ecb/decb roms as there are addresses pointing to certain locations. So I would think if ecb is at $0000, then decb would be at $4000??? (org $8000 & $c000)
I have no DE1 and know nothing of this, just using logical addressing.

Yes Bob. This had me curious but any docs I have found state that ECB
should be at 0000 in flash RAM.

It must be right because this part is working.

I don't understand the relationship with the Flash RAM locations and
how they relate to the real address.

The CoCo3 ROM image is 32K so obviously, it occupies the whole upper
32K.

How does the CoCo3 deal with Disk Basic?

I know it copies it to RAM and then patches it for Super Extended
Basic. How is Disk Basic managed?

 Nick,

 I'll admit I know nothing about the DE-1, but in a *real* coco, the
ECB rom 
 is at 08000 and the DECB is at 0C000. Are the memory locations in the
flash 
 related to the locations in the real coco? ECB looks at the two bytes
at 
 0C000 to see if DECB exists.
