Basic OperationsCOMPONENTSThe Xerox 1108 is a compact, personal Interlisp-D workstation consisting of a processor, display,keyboard, mouse, floppy disk drive, and a rigid disk drive.The DisplayThe display is a large format CRT (17" diagonal) with a high resolution bitmap (1024 x 808pixels). Intensity is controlled by a lever under the left side of the screen. The display may betilted back and forth to maximize comfort and minimize glare.The KeyboardThe keyboard consists of 78 keys, 24 of which are function keys. All 78 keys are unencoded. Themaximum distance between keyboard and processor is approximately 8 feet.The MouseThe mouse is one of three types: 2-button mechanical, 3-button mechanical, or 3-button optical.The middle key of the 2-button mouse is the CENTER key on the keyboard. If you have an opticalmouse, use the specially designed grey, hexagon-patterned paper as a mouse pad. The mouse isattached to the keyboard with approximately 2 l/2 feet of thin cable. The ProcessorThe processor houses a floppy disk drive, a 10 or 43 Megabyte rigid disk, and six printed circuitboards: the IO processor, Central processor, High Speed IO processor, Memory Storage, MemoryControl, and the Options board. A serial port (RS232) is located in the rear of the processor. If the29 Megabyte rigid disk is used, it is housed in a separate box.The Rigid DiskThe rigid disk has 10, 29, or 42 Megabytes capacity. Depending on size, it is divided into two ormore logical volumes. Each logical volume has a name and length. Instructions are provided forloading each volume with the appropriate software.The Floppy Disk DriveThe floppy disk drive is located on the front of the processor.To load a floppy disk:1. Locate the floppy disk drive on your processor. If the door is not open, press the long, narrowbar (with the circle in the center) immediately below the drive.2. Floppy disks normally are labeled to indicate which side should go in and which side should befacing up.3. When the disk is fully into the drive, you will hear a click. When you release the disk, it willpop out if it was not fully into the drive. bAp>5 \1qa. V!r SsNa Q; Nr Ks] Jd H|= Etr Blsb @H =r :s_ 9T^ 7] 6KE 4 3Cr 0;sa .\ -3f +?

Make sure the red read/write light (circle in the center of the drive door bar) is notilluminated.2. Press the drive door bar.3. Remove the disk and store it in its jacket.When storing floppy disks, keep them away from magnets, dust, and heat. Do not bend them.Do not write on their labels with ball-point pens or pencils of any sort. Any of these actions coulddamage the disk and prevent successful use of it.Service considerationsTo make sure the Xerox technical representative has enough room to access the display screen,position the display so that there is a total of 14 inches minimum on the sides. The Processorshould be positioned to provide access to the front panel of the unit. You will need access to thefront panel to load floppy disks and to turn the processor on and off, or boot the system. Makesure there is sufficient air movement around the processor, so it is not damaged by the heat itproduces. The back of the processor must be at least 6 inches from the wall. If possible, provideenough space around the processor for servicing by the Xerox technical representative. An area4 feet long by six feet wide, or an area that size in front of the processor so that it can be pulledout, is sufficient for servicing. The processor should be positioned in a permanent location.Bumping and jarring it hard enough, even when turned off, can destroy the magnetic heads orthe media. If you must move the processor, take care not to suddently jolt or bump it.RS232Two serial ports are available: a standard RS232 port and a TTY port, labeled Printer/DTB.Xerox supplies a standard cabel for the former; special cabling is required by the latter,depending on the particular application. For a complete description of RS232 software support,please consult documentation for the RS232 Lisp Library package.Nfs bN. _ \Z Z W Ty/ Qq[ Oe Ni1 Kat HYs] Fb EQc C` BI_ @d ?A_ =e <8_ :[ 90W 6(r 3 sNt s 1Z 0_ .@r +E<<{3OPERATIONSTurning on the ProcessorNote: Wait at least three minutes if you decide to turn the processor on after turning it off.1. Pull down on the cover of the Maintenance Panel if the cover is closed.2. Before turning the system on, simultaneously press both the B RESET and ALT B buttons onthe front panel and push the rocker switch to the 1 position. The maintenance panel will displaythe numbers 8888. Release the B RESET and ALT B key.Booting the ProcessorThe software delivered with your Xerox 1108 is bound into a runnable package called a boot file.The process of loading a boot file into the 1108 is called booting. Boot files may be booted fromeither the rigid disk or a floppy disk. Normally, the rigid disk is set up so that powering up theprocessor resumes the last Interlisp-D session. If the rigid disk has not been properly initialized,the only alternative is to boot from a Xerox-supplied bootable floppy.Two types of booting are available on the Xerox 1108: normal booting and alternate booting.Normal booting assumes that Interlisp-D has been properly set up in a logical volume of the rigiddisk. Alternate booting allows for booting of utility software from the rigid disk or a floppy disk.If Interlisp-D is properly installed, a normal boot is performed by pressing and releasing the BRESET (left) boot button. The maintenance panel will go blank and then display 8888 for a fewseconds. A succession of maintenance panel codes will then be displayed during the bootingsequence. The booting process completes with 0000 in the maintenance panel. Interlisp-Dshould be ready within about 10 seconds. If you ended a previous Interlisp-D session by loggingout, a normal boot will resume that session. If you are running Interlisp-D for the first time, themost recently installed logical volume will be booted.To perform an alternate boot, press both B RESET and ALT B buttons, then let go of B RESET.The maintenance panel will go blank, show 8888, then cycle slowly and repeatedly through thesequence 0000, 0001, ..., 0010. Release the ALT B button when the desired number is showing.The options are:0000 Boot Interlisp-D from a logical volume on the rigid disk. Usually, the logical volumeselected will be the one containing the most recently used Interlisp-D system; i.e., if youterminate an Interlisp-D session with LOGOUT, then 0-boot will resume that session from whereyou left off. However, if the most recent activity was installing a fresh Interlisp-D system on alogical volume, 0-boot will boot from that logical volume. (Note, to boot Interlisp-D from anylogical volume, use the Install Lisp Tool.)0001 Boot the 1108 into its base state. From this state it is possible to start utility programs suchas diagnostics, or a tool to install and start Interlisp-D on different logical volumes.0002 Floppy boot (suppress diagnostics). Only specially configured Xerox floppies, such theInstallation Utility, or EI Fixed Disk Diagnostics, may be booted this way.0005 Floppy boot (with diagnostics). This is identical to a 2-boot, except that machinediagnostics are run automatically before the floppy is booted.0010 Floppy disk drive head cleaning function (see below.)Turning off the ProcessorNfs b _rN \t_ YsK U@rsrs Tyb Rrsrs Nir KasVts I;ts HYc Fd EQF BI[ @a ?Ae <8_r :sY 90[ 7Y 6(` 4d 3 6 0)rsrsrs .\ --rs+ + (rsX '[ %|] #b "s_ ts rst s@ cX [rsY tsts rsU K?

Before you turn the system OFF, press both the B RESET and ALT B buttons on theworkstation front panel and push the rocker switch to the 0 position. Continue to press both theB RESET and ALT B buttons for approximately 20 seconds, then release them.This procedure allows the disk to spin down properly.Nfs bNS _3rsrs ]` \rsrs9 Z5 W:;-5ROUTINE MAINTENANCECleaning the Floppy Disk Drive Heads Once a month, or after every twentieth time that you use the floppy disk drive, you should cleanthe floppy disk drive heads.If the magnetic heads are not kept clean, they can accumulate deposits that will cause scratchingand erasure of data on the disks while reading and writing.Use the following procedure to clean the floppy disk drive heads with a Xerox head cleaning kit:1. Remove the cleaning disk from its white jacket.2. If you are using a disk that has not been used before, remove the perforated tab from the blackdisk jacket.3. Turn the head cleaning disk over and dispense about l/2 teaspoon of the disk cleaning solutionover the large cutout area.4. Insert the head cleaning disk into the floppy disk drive with the perforated tab facing upward.5. Do a 10-boot.6. When the maintenance panel displays 0076, press the ALT B button. 0077 will be displayedfor about 15 seconds while the drive is being cleaned, then 0076 will be displayed once again.7. Press the floppy disk drive latch and remove the head-cleaning disk. Place an X in theappropriate usage box on the disk. When the disk has been used 13 times, it should be discarded.Note: Head cleaning can also be performed by running diagnostics from the base state, selectingFloppy Disk Drive, and then selecting Clean Heads. Explicit prompting is supplied by the CleanHeads command.Cleaning the Mouse Pad, and Checking the MouseBrush or wipe the dust from the surface of the plastic mouse pad, since dust can interfere withthe ball bearings of the two-button mouse, and the lens of the three-button mouse. Move themouse in circles on the mouse pad and check the movement of the cursor on the display screen tomake sure it is operating smoothly. If you see any hesitation in the movement of the cursor orfeel the ball bearings rubbing (two-button mouse), it should be cleaned by a Xerox technicalrepresentative.Cleaning the Display ScreenLightly wipe your display screen with a damp cloth or spray it with window cleaner. CAUTION:do not allow any liquid to drip down into the housing around the screen.Cleaning the KeyboardBrush off the keyboard to keep dust from building up under the keys.Nfs bN _t$ ]s \` Z Wa U; R` O3 Lc Ka HYb F Cc @ =(rs rs rs <8
