Backing up the system diskette
1) Unwrap the CP/M system disk which comes with the system and insert it in the
drive (drive A in the CP/M nomenclature).
Insert it with the labeled side
upwards with the edge closest to the oval exposed region going in first.
Push
it in until it clicks in place.
Mount the disk by pressing the door slowly
downwards, pausing briefly at the mid-point, when the spring-pressure
increases.
Full instructions for use of the disk drives and handling floppy
diskettes are found in the CP/M 2 System Diskette Introductory Manual enclosed
with the system.
Make allowance for the fact that your drive is oriented
horizontally rather than vertically.
2) Boot up the CP/M operating system by depressing B on the keyboard, following
the MaN> prompt.
The red light on the upper right-hand corner of the drive
should light up, an audible click should
be
heard from the disk drive, and then
a message announcing the CP/M operating system should appear on the screen.
If this does not occur within 5 seconds of pressing B, depress RESET on the
rear of the computer Chassis, then dismount the dTsk.
To
disroc>unt a disk,
press the door latch further down until it springs open.
Then move the door
lever upwards to partially eject the diskette.
Remove the diskette fran the
drive
and
make sure that (a) it is the serialized CP/M 2 disk that came with
the system, (not from a different system), and (b) that it is oriented
correctly as described above.
Then remount it carefully.
Depress the RESET
key on the computer chassis and try the
~
cormnand again.
If still no CP/M message appears, repeat the process of RESETTING,
disroc>unting, checking the disk, remounting and rebooting once again.
Then, if
there is no CP/M message, try the same process but use a CP/M 2 disk from a
different system.
If none of these diskettes will boot up, the chances are
that there is something wrong with the disk subsystem that requires the help of
service personnel.
3) When CP/M boots up, you should see an A> pranpt on the screen following the
sign on message.
Type
DIR (return) following the prompt.
(return) means press
the RETURN key.
You do NOT have to use capital letters when typing a CP/M
canmand.
You should immediately see a directory of the files on the diskette,
consisting of at least 5 lines of names.
Make sure there is a file named
BACKUP.
'This will be used next.
4) You are now going to copy the CP/M serialized diskette.
This has the double
function that it tests the disk drives for compatibility and it gives you a
working copy of CP/M - the copy which will become the Personalized CP/M 2
System Diskette.
C£t a completely unused diskette (or one whose contents are
not needed).
Make sure it is a Dysan, Scotch, or Maxell brand 16-sector
diskette.
'These are the only types of diskettes you should use with the Vector
Graphic system at this time, due to the high density of storage employed; other
brands have been found unreliable in this system.
At this time, Scotch seems
to
be
the iIDst reliable of the brands.
