PC-Ditto will use any TOS partition.  It would prefer to muck with C:.
(See below also.).  MAC, if done by Spectre or Magic Sac, will  gladly take
a TOS partition (empty I hope), destroy it, and make it its own.  At which
time it will be known as ACK.  SO,

You must have a partition for MAC, and at least one for TOS/PC-Ditto.
Because of how MAC uses partitions I would recommend:

30 Meg total:
	First for TOS, will be called C: 10 meg or so
	Second for TOS, will be called D: 9 meg or so.  Or just one for 19 Meg.
(16 meg max  for TOS 1.1)  Use TOS for  PC-Ditto.
	Third for MAC, 1 meg: used to 'boot' up mac. -- read manual.
	Forth for MAC, 9 meg: or more; use for data storage. (The more the better).

The letters are assigned by TOS and the driver.  It is not in the partitioning.
First TOS partition is C:
Second TOS partition is D:
If the partitions are labeled in a different order, first TOS means just that,
not the FIRST one.

A Ramdisk must be COMPILED or CONFIGURED for is letter.  if you want it to be
G:, and do not know how to configure it, its probably hardwired to be C:.  

Get another RAMDISK.
