[Coco] Strange.... two 40 track disks on one 80 track disk?

[Bruce W. Calkins]

My recollection was that you needed to change the track count from 0 to 39 
to 40 to 79 for that drive.  The second "disk" would have the same structure 
as a normal disk aside from the track numbering.



I do not remember if it was as easy as a couple pokes, of if it was more 
complicated.
