Apple Macintosh LC 630 DOS - Manual (Page 59)

For example, if you use M as your LASTDRIVE value, you could have up to
nine extra drives using drives labeled E through M. A CD-ROM drive, if
installed, uses E.
Each additional drive letter uses 100 bytes of PC memory.
Clipboard
You can exchange clipboard information between the PC environment and the
Mac OS. The type of information you can exchange depends on whether
you’re running DOS or Windows.
Windows Clipboard
You can exchange text, PICT, RTF, and bitmap files between the Mac OS and
Windows using the Copy and Paste commands from the Edit menu. You can
also purchase additional third-party software to provide translations for other
data types.
DOS “Clipboard”
If you’re running DOS, you can capture text or a PICT file from a region of
the screen that you define using the DOSCLIP TSR (Terminate-and-Stay-
Resident program). The memory-resident program is loaded automatically
each time you switch to DOS. You activate DOSCLIP by pressing a keyboard
combination, or keystroke, (preset to Shift-Control-C) and then selecting a
region to copy.
Keystroke starts process: On the PC side, enter the keystroke first; then,
holding down the mouse button, select a region to copy. (This process works
only if a DOS mouse driver is installed.) Releasing the mouse button sends
the selection to the Clipboard. In the Mac OS, you select the area first and
then issue the keystroke.
