Epson 10020 - Manual (Page 35)

You need to set the date and time this way only once; the
computer’s real-time clock keeps track of the date and time
even when the computer is off. The next time you load
MS-DOS, you can just press Enter when you see each of
these prompts to accept the displayed date and time.
MS-DOS updates months and years correctly-whether the
month has 31, 30, 29, or 28 days—and even accounts for leap
years. You may need to change the time later, however, to
accommodate a change such as daylight savings time.
Note
You can also change the date and time with the Setup
program or with the MS-DOS DATE and TIME commands.
The Setup program is described in Appendix A. The DATE
and TIME commands are described below for the Apex
100\20 and in the MS-DOS manual.
The Command Prompt
The command prompt tells you that MS-DOS is loaded and
your computer is ready to receive instructions. It also identifies
the current operating drive: A, B, or C. The command prompt
appears on the screen whenever you load MS-DOS, complete
an MS-DOS command, or exit an application program.
On the Apex 100, the top diskette drive
is
drive A and the
bottom diskette drive is B. On the Apex 100\20, the diskette
drive is A and the hard disk is drive C. MS-DOS reserves the
label B for a second diskette drive, whether or not it is
installed.
If you load MS-DOS from a diskette in drive A, the command
prompt looks like this:
