1. The Cartridge Tape Drive
Chapter 1
THE CARTRIOOE TAPE DRIVE
The Cromemco Cartridge Tape Drive (CTD) offers Cromemco system users a
convenient,
low-cost alternative to floppy disk drives for storing large amounts
of
data. With aformatted capacity of 26 megabytes per tape cartridge, and an
average
data-transfer rate of 1megabyte per minute, the CTD is particularly
useful for backing up hard disk drives.
The
CTD is compatible with all Cromemco S-100 bus systems having a64FLC
board,
512 Kbytes of RAM, and either the 68000 Crornix Operating System (Cromix
20-Series) or the Cromix-Plus Operating System (version 30.73 or higher). A
diskette with supplemental CTD software is included with each drive.

Cromemco CTD Instruction Manual
1. The Cartridge Tape Drive
INSTALLING THE CTD
To attach the CTD to your sy stem, follow the appropriate set of instructions
listed below. Before installing the drive, check the revision and mod level of
the 64FDC board (the revision letter is etched into the solder side of the board,
and
the mod level number is indicated by a label, also on the solder side). If
you do not have aRevision Dboard with mod level 7or higher, then the 64FDC
must be modified (refer to the last section of this chapter, "Using the 64FOC
with the CTD").
System One and System 100
Adding aCTD to model CS1 (two 5-1/4" floppy drives) precludes the addition
of another floppy disk drive. However, model
CS1H and System 100 (one 5-1/4"
floppy drive and one hard disk drive) can
support both a CTD and another floppy
disk,
in which case the second floppy disk becomes Drive B, and plugs into the
back of the CTD connector.
Install the CTD as follows:
1. Turn off the system, and remove the upper and lower rear panelsas
described in your system manual.
2.
secure the drive cable adaptor (figure 1-2) to the new connector panel
(part number 016-0330), as shown in figure 1-3. If you -have aSystem 100,
which has
the new panel already installed, unscrew the cover from the
drive connector slot, attach the adaptor, and go to step 4.
3. Disconnect
all cables from the rear panel. Unscrew the connectors from
the old
rear panel and secure them to the new one.
4. Plug one end of
the 50-conductor cable (part number 519-0209) into J 3
on the
64FDC board, and plug the other end into J3 on the drive cable
adaptor. The red cable stripe should be to the right as you face the back
of
the sy stem.
5. Replace
the rear panels and reconnect all cables. Plug the CTD cable
into
the drive connector.

System Two
Adding a
CTD to any model of the System Two precludes the addition of another
floppy disk drive.
Install the CTD as follows:
1. Turn off the sy stem, open the front panel, and remove the top cover as
described in your system manual.
2. Plug one end of
the 50-conductor cable (part number 519-0210) into J3
on the 64FDC board, with the red cable stripe towards the bottom of the
system.
3. Feed
the cable through one of the connector cutouts on the rear panel,
and plug the cable into J3 on the drive cable adaptor. The cable stripe
should be to the left, as shown in figure 1-2.
4. Close the system, and plug the CTD cable into the drive cable adaptor.
System Three and System 300
.adding aCTD to model CS3 (two 8" floppy drives) precludes the addition of
another floppy disk drive. However, model
CS3H and System 300 (one 8" floppy
drive and one hard disk drive) can
support both aCTD and another floppy disk,
in which case the second floppy disk becomes Drive B, and plugs into the back
of the CTD connector.
Install the CTD as fallows:
1. Turn off the system, open the front panel, and remove the top cover as
described in your system manual. Pull out
the card cage and remove the
retaining
bar.
2. Plug one end of the 34-conductor cable (part number 519-0208) into J2
on the
64FDC board (with the red cable stripe towards the top of the
system), and run
the cable to the rear panel.
3. If your system has a rear connector panel (see figure 1-4), go to step 4;
otherwise, feed
the cable through one of the connector cutouts on the rear
panel, and go to step 8.
4.
secure the drive cable adaptor (figure 1-2) to the new connector panel
(part number 016-0327), as shown in figure 1-5. If you have aSystem 300,
which has
the new panel already installed, unscrew the cover from the
drive connector slot, insert the adaptor, and go to step 8.

INSERTING A TAPE CARTRIOOE
The CTD requires 1/4" tape cartridges of the type LC600A (the earlier model
DC300 does not work). All cartridges must be formatted as described in chapter
2; "pre-formatted" tapes are unnecessary because they must be converted to
Crom emc0'sformat.
Never insert a cartridge into the drive unless the power switch is ON.
First plug the CTD into awall socket and press the power switch on the back
panel. Turn the drive latch down, and pull the cartridge tray out from the drive
slot. With the tape reels up and the dust cover towards you, insert the cartridge
into the drive (see figures 1-6 and 1-7). Gently push the cartridge in until it
comes to a stop, then turn the drive latch up to lock the cartridge in place.
To re-tension the tape, the CTD automatically runs it from beginning to end and
back
to the beginning again.

The Write-Protect Switch
The write-protect switch on the tape cartridge (see figure 1-7) can prevent
sensitive
data from being altered or destroyed. If the arrow on the switch points
to
SAFE, the tape can be read, but it cannot be written to or erased. If the
arrow points in the opposite direction, the tape can be read, written to, and
erased.

2. Using
the CTD Software
Chapter 2
USING THE CTD SOFTWARE
This chapter describes how to load the CTD software, initialize a tape cartridge,
and transfer files to and from the CTD. These procedures are different for the
Cromix-Plus and Cromix 20-Series Operating Systems, so follow the
appropriate
set of instruction listed below.
CROMIX-PLUS OPERATING SYSTEM
If you have the Cromix-Plus Operating System (version 30.73 or higher), do not
load the software from the CTD diskette (earlier versions of Cromix-Plus do
not support the CTD). If your current cromix.sysprogram does not include
the CTD driver, use the Screen editor to add tflop to line "BDEV 04
11
in the
Igen/sysdef file, and generate anew cromix.sys.
Initializing aTape Cartridge
Every
tape cartridge must be initialized with the Inittape utility (for privileged
users) before
it can be used to store data. The general command format is
inittape [[-vf] [-s #[,#] devname]
If the Inittape parameters are not placed in the command, you will be prompted
for them as the program executes.
Insert a cartridge into the drive, as described
in chapter 1, and enter (user entries are boldfaced):
• inittape
Inittape version 30.xx
Press:
RETURN to supply default answers
CTRL-C
to abort program
Warning:
inittape will destroy all disk data
Do you wish retension delay of 180 seconds (YIN) <N>? RETURN
Devicename? ftcd

2. Using
the CTD Software
Fonnatting
First stream (0-5.)? <0> RETURN
Last stream (0-5.)? <5.> RETURN
lnitializing stream 0
Initializing stream 5
The CTD retensions each
tape when it is first placed in the drive by mnning
it from beginning to end and back to the beginning. If the retension cycle is
over (the drive light is out), press RETURN for the first prompt.
Next,
Inittape asks for the device name of the tape drive. Use the device name
of any
tape drive connected to your system, such as fted or ftab. Entering a
device name while the
tape is being retensioned results in adevice open error
and arepeated prompt for the device name.
lnittape prompts for the first and last stream to be fonnatted. On occasion, you
may want to format aportion of a tape (e.g., when asingle stream has frequent
errors).
If Inittape is called with adevice name argument, the responses to the above
prompts
are taken from the command line. If no options are specified, all
streams are formatted. The available options are defined as follows:
-f This option defeats the tape retension delay, but using it While the tape
is being retensioned results in adevice open error.
-8 If asingle number (0 through 5) follows the -8 option, only the specified
stream is formatted; apair of numbers separated
by acomma specifies a
range of streams
to be fonnatted.
-y The "verbose" option provides progress reports as formatting proceeds.
For example,
to fonnat streams 1through 3in verbose mode, enter:
if inittape -y -8 1,3 fted
Please wait for tape retension time (180 seconds)
