Please note that Switch 4 is not a Test Function, but a selector for logic signals that MUST be set according to the device attached. SWITCH 4 MUST BE OPEN WHEN A STREAMER IS ATTACHED OR AN ERROR WILL BE DETECTED WHEN EOT IS REACHED, RESULTING IN AN "EARLY TRACK CLOSEOUT" CONDITION. Following the table is a description of the self-test functions and some information regarding Streaming Backup/Restore operation with BBIITS. Streamer Controller Self Test: The controller board has a local self-test capability whic verifies correct functionality of the streamer interface. An 8 position DIP switch controls the self-test firmware and it's settings are listed below: SWITCH CLOSED OPEN ------ --------- ------------------- 1 Self-test Idle Enable (Normal operation) 2 Unit 0 Unit 1 3 Low Speed High Speed (25 IPS) (100 IPS) 4 MTR MTS (Drive type, (Drive type, not mode!!) not mode!!) 5 Read Write 6 Forward Reverse (read only) 7 $00$ data $FF$ data 8 124 byte 4096 byte record record All switches except 1 & 4 are exclusively used for testing. Switch 4 should always be set to the typr of drive connected to the controller, even during self-tests. Switch 6 effects only reads in self test. Write is only done in the forward direction. TO RUN THE SELF TESTS: Place switch 1 in OPEN position. Load or rewind tape to BOT. Reset controller. This can be done by momentarily pressing the load button on the processor. The green test light should be ON indicating the self-test was O.K. and the firm- ware is looping in idle. Set all switches except switch 1 to write records out to end of tap. A variety of tests can be set up. Place switch 1 in CLOSED pos- ition and proceed to write records to EOT. At EOT the drive will begin to MAGNETIC TAPE I/O-CIPHER-F880,MTS-------------------FIB004 Pg001 rewind. While rewinding, place switch 1 to OPEN. Now, set switch 5 to READ. After stopping at BOT, reset the controller again. Start reading by setting switch 1 to the CLOSED position. The test light should stay on. If the test light goes out, it indicates either a data error or a byte count error. The ight will stay out until EOT and a subsequent automatic rewind. Then the light will go on and the test will start over. This loop will continue as long as desired. All tests begin from BOT after performing a reset. Data may be read in reverse, in which case the test still starts from BOT. Write is always in a forward dir- ection and then switch 6 has no effect. Do not change switch settings after tape has started moving from BOT. During write, an error detected by read-after-write will generate a write gap and continue writing to proceed over tape defects. The test light will momentarily go out indicating a write gap. All normal operations with the controller with the CPU require tha switch 1 be OPEN or the controller will not respond to the CPU. MTS OPERATING MODE (STREAMING MODE): Streaming mode requires the use of a single user, dedicated operating system (entered by alt-loading "BBIITS") and enables disk image back-ups and restores at a tape motion rate of 100 IPS> This operating system is extremely limited and does not have a console mode compatibility. After system start-up, the user is automatically transferred to the streamer utility "*DMPST". Even in streaming mode the MTS retains the ability to skip over bad sections of tape. "HICCUPS": "Hiccups" (when streaming , the MTS momentarily stops tape motion because it is waiting or retracing) usually occor under one of two circumstances: (1) a bad or marginal section of tape is encountered or (2) the disk must seek to an alternate track. It is not unusual for several "hiccups" to occur during a back-up or restore. ORIGINATOR: J.

The only legal operations when this bit is set are Read Main Status, Controller Reset, Enable Interrupt, Read Count High, Read Count Low, and Read Alternate Status. Bit 6: Rewinding - When this bit is true, the selected drive is in the pro- cess of rewinding and cannot acept any commands. Bit 5: File Mark - This bit is set true after a Write File command or after a Read or Space command that terminates immediately after traversing a File Mark record. Bit 4: EOT - This bit is set if the tape on the selected drive is at or beyond the End of Tape. Bit 3: BOT - This bit is set if tape on the selected drive is at the Beginning of Tape. Bit 2: CRC - This bit is set during a Read/Write operation when the CRC does not check correctly in the previous operation. Bit 1: CR - This bit is set if the controller is issued an undefined command (with AC) or a legal command while the controller is busy (without AC). MAGNETIC TAPE I/O-CIPHER-F880,MTS-------------------FIB007 Pg001 Bit 0: Abnormal Condition - This bit amplifies the FP, BOT, EOT, CRC bits. When set in conjunction with FP, the AC indicates a Write command was issued to a File Proteced tape. The command is ABORTED. When set in conjunction with EOT, AC indicates that a Space Foward File command has been issued after the tape heads have passed the EOT marker in the foward direction. The command is ABORTED. When set in conjunction with BOT, AC indicates a Space Reverse command was issued when the tape was positioned at BOT: The command is ABORTED. When set in conjunction with CRC, AC indicates a data drop has occured during a Read/Write command. When set in conjunction with SE, AC indicates that a recoverable error has occured in Write (PE only). However, the record is to be rewritten as if a Hard Error (CRC) had occured. SE set without AC indicates that a recoverable error had occured in Read (PE only). Also, AC will be set if the NOT READY or OFFLINE situation occure. The command is ABORTED. When set in conjunction with REW, AC indicates that a command was issued while the transport was busy rewinding. The command was ABORTED. When set in conjunction with DBC, AC indicates that the DMA Byte Count was equal to or less then zero. The command was ABORTED. When set in conjuncation with CR, AC indicates that an undefined command was issued. When set in conjunction with RE, AC indicates that DMA has not kept up with the tape transfer rate. The command is ABORTED. All status indications accompanied by AC produce a termination interrupt. Bit 7: RDY - When this bit is set, the selected transport is ready to accept a command. Bit 6: UN - This bit reflects the Unit Number of selected transport. Bit 5: FP - File Protected. This bit is set if the tape on the selected drive has no write ring. Bit 4: OFL - Off Line. If this is set, the selected transport is in the Off Line condition and will not accept commands. Bit 3: TM - Test Mode. When this bit is set, the controller is in Test Mode. Bit 2: SE - Soft Error. When this bit is set, it indicates that a recoverable error was encountered in the previous Read/Write operation (PE only). In Read operation SE is set without AC. In Write operation SE is set with AC; the record is to be rewritten as if a Hard Error (CRC) had occured. Bit 1: DBC - DMA Byte Count is in error (equal to or less then zero). Bit 0: RE - Rate Error. When this bit is set, it indicates that either the DMA has not kept up with the data on the tape (READ), or WSTR has exceeded the DMA rate (WRITE), or WSTR is slow or missing (WRITE).

The problem is with the program logic that checks for the logical end of tape. It is easly repaired by modifying line 8500 of the streamer tape programs, "*FRTPE", "*FSTPE", and "*RSTPE". Line 8500 of all three programs currently reads: 8500 IF T$(1,5)="*eoi*" THEN PRINT IOL=6070; EXITTO 9820 ELSE 8500:LET I+LEN(T$)/1024; IF FPT(I)<>0 THEN PRINT IOL=6020; 8500:EXITTO 9820 Modify line 8500 to include the following underlined code as well: 8500 IF LEN(T$)=5 AND T$(1,5)="*eoi*" THEN PRINT IOL=6070; 8500:EXITTO 9820 ELSE LET I=LEN(T$)/1024; IF FPT(I)<>0 THEN 8500:PRINT IOL=6020; EXITTO 9820 This addition can be done by executing the following EDIT command: EDIT8500 C[IF],[LEN(T$)=5 AND] --------------------------------------------------------------------------- THIS REPAIR IS HIGHLY RECOMMENDED FOR ALL 4.4A, 4.4B, and 4.5A STREAMER TAPE INSTALLATIONS ---------------------------------------------------------------------------- The next 13xx release will contain the streamer fix in the streamer utilities.

This option enables the System 2000 to use the Model 4402 Cipher 1/2" Streamer Tape Drive, the same drive used with other Basic Four systems, to do backups and restores of the hard disk. The tape drive may also be used to transfer data files to other Basic Four systems. The following items should be available at installation time: * Formatter Controller box, MBF Model 4602. It contains the formatter and the power supply. * SCSI Bus Adapter Board, P/N 903528-001 to be installed inside the 2000 system. * Interface cable P/N 906608-017, from 2000 Bus Adapter to Controller Box. * Cipher 1/2" Streamer Tape Drive, MBF Model 4402. * Operating System Level 7.2A*27 or above. * Diagnostics Media Level DIA 7204 or above. HARDWARE INSTALLATION: 1. Open the controller box by loosening 1 screw on each side and sliding the tray towards the front. Inspect formatter controller board (NCR ASSY 348-0014807A) to verify switches and jumpers settings: * Dip SW. 1 at location 7W: all positions should be set to CLOSED. * Jumpers W22, W23, W24 at location 6J should be OPEN. All other jumpers on the board should be ON. * Terminator Packs in place at locations 6H and 7B. Test the operation of the controller by running the self-tests: Controller self-tests are started when the power switch is turn ON in the controller box. Self-tests may be re-started by pressing the Reset Sw. on the formatter board. There are 8 Leds marked from '7' (MSB) thru '0'. The upper half should always display a '9' (bits 7 and 4). The lower half changes with the test being run. The LEDs should display: '9F' while doing Data Buffer Test. '90' at the end if everything worked OK. 2. Position the controller box within 6 feet of the System 2000. Allow 4 inches clearance in the back for proper air ventilation. 3. Place the Streamer Tape Drive in top of controller box, 2 persons are MAGNETIC TAPE I/O-CIPHER-F880,MTS-------------------FIB016 Pg001 needed. The 4 rubber stand-offs should fit in the 4 holes in the controller box. 4. Before attaching the 2 ribbon cables from the controller box to the tape drive check the position and orientation of the cables in relation to the tape drive. The cables may have to be twisted, on the tape drive end, in order to connect the cables as follows: J1 on the formatter board should connect to P1 on the tape drive. J2 on the formatter board should connect to P2 on the tape drive. On both cables, make sure that pin 1 in one end is connected to pin 1 in the other end. 5. Install SCSI Bus Adapter, P/N 903528-001 in the system 2000 controller stack. Verify that dip switch SW. 1 positions 1, 2 and 4 are ON. 6. Connect cable P/N 906608-017 from the 2000 Bus Adapter to the controller box. The end marked "PA" should be attached to the Bus Adapter. Viewing both units from the rear, pin 1 is located as fo On the 2000 Bus Adapter board, pin 1 is on the right hand side. On the Controller Box, pin 1 is on the left hand side. TESTING THE OPERATION: 1. Turn power on to the controller box, the tape drive and the system 2000. The system 2000 console will not print a test resulf for the Bus Adapter during the self-tests because the Bus Adapter board itself does not perform self-tests. 2. Load a reel of tape in the tape drive with the write enable ring in place. After the tape is successfully loaded, the LOAD and the WRTEN lights should be on. Press the ON LINE switch to place the drive On Line. 3. Using Diagnostics to test tape drive operation: Boot diagnostic media level DIA 7204 or above. Load 'mts'. Enter 'quick' after the prompt to run the tests in quick mode. The 'mts' tests in quick mode takes about 8 minutes to run. It should run with no errors. Tests 1 to 11 check the Bus Adapter board by itself, the rest of the tests require a ready tape drive and controller box. 4. Using the command language to test the tape drive with the Operating System: The following commands are included in 7.2A*27 release: mtslabel, mtssave, mtsrestore, mtscompare. These commands operate in a similar manner to the ones used with the 1/4" mcs. Use 'mtslabel' and 'mtssave' to write to tape, and then use j'mtscompare' to compare the tape to the disk.

VANDER HEYDEN MAGNETIC TAPE I/O-CIPHER-F880,MTS-------------------FIB017 Pg001 FIB 00018 12/07/87 *** Erase Head Wiring Check *** SYMPTOM: Intermittent read errors when attempting to read tapes created on tape drive with a miswired erase head. Problem is usually caused when the head is replaced or write cable is replaced. PROBLEM DETERMINATION: Visual inspection of erase head wiring. Wire/pin 22 (erase VCC) should be connected to lower pin of erase head as viewed from the top and wire/pin 21 (erase return) should be connected to the upper pin. Some cables have color coded sleeves (red & black) with red connected to the lower pin and black connected to the upper pin. FIX: Correct wiring if miswired.

FIX: Don't overlook the front panel switch asm. as the cause. If you suspect the switch asm, it can be checked from the front of the machine. Pull off the switch overlay (it is glued on). Inspect the pressure sensitive on line dot. If it or any other dots show signs of flaking, worn spot in the middle, this may be your problem. Replace switch, P/N MM638030 (switch and overlay). It can be changed from the front of the machine. It is glued on, and the attaching cable is long enough.

ORIGINATOR: Harvey Mitchell MAGNETIC TAPE I/O-CIPHER-F880,MTS-------------------FIB022 Pg001 FIB 00023 07/18/90 *** EOT Sensor Failures with 3-PROM firmware set *** SYMPTOM: Power-On Selftest, Load, and Read/Write functions work OK, but may miss EOT sticker and run off end of tape due to low output of EOT /BOT Sensor Assembly. PROBLEM DETERMINATION: Formatter PCBA has 3-PROM firmware set in locations U6N (961634-001), U8N (961634-002), and U10N (961634 -003). Above-mentioned firmware does not test for minimum output of BOTH EOT & BOT at Power-On. EITHER EOT or BOT having minimum output will allow tape load to be performed. If BOT output is below minimum, tape will miss BOT and fail after LOAD-POINT search. If EOT output is below minimum, drive will miss EOT. FIX: Test the EOT/BOT Sensor output as shown below and replace any sensors with lower output than specified> WITH NO TAPE-IN-PATH Step 1 Activate Service Aid (SA) 22 (BOT Test). If the OCP indicators show a binary count >= 5, then the sensor meets the criteria for no-tape- in path. Skip step 2 and proceed with step 3. Otherwise proceed with step 2. Step 2 Activate SA 23 (EOT Test). If the OCP indicators show a binary count >= 5, then the sensor meets the requirement for either EOT or BOT minimum output with no-tape-in-path. Exit SA 23, re-enter SA 22, and proceed with step 3. Step 3 Position a blank tape in the tape path from Supply reel to Takeup hub. Keep the tape taut for this and the following steps, so there is no slack. The OCP indicators must indicate a binary reading of <= 4. Step 4 Position a BOT reflective sticker in front of the Sensor (Top edge of tape). The OCP indicators should show a binary reading of >= 8. Step 5 Exit SA 22 and enter SA 23. Repeat steps 3 and 4 for the EOT sensor using a section of tape having an EOT reflective sticker in step 4. This information is from CIPHER Product Improvement Bulletin 088-0022. The Repair Center reports several Formatter PCBAs have been returned erroneously after having been replaced for the EOT failure. The sensor assemblies with low output may work slightly better (less intermittent) with one PCBA than another, but cannot be considered reliable until tested as above. ORIGINATOR: J. VanderHeyden MAGNETIC TAPE I/O-CIPHER-F880,MTS-------------------FIB023 Pg001 FIB 00024 08/31/90 *** Tape Boot Fails on MPx & ASx Systems, Intermittant Read Errors *** SYMPTOM: Tape boot fails on MPx & ASx systems with bootstrap error E086, may also give intermittant read errors. PROBLEM DETERMINATION: Disconnect the I/O cables, and check for logic ground to frame ground continuity. Meter between the outer steel chassis (not the aluminum deckplate which is also logic ground) and any ground test point on the formatter PCBA. There should be a dead short. FIX: If there is no logic to frame ground connection in the drive, it has been disconnected and must be reconnected for reliable operation. There are two possible places where the connection may have been broken depending on the age of the drive, the newer style drive is listed in step 1 and the older style in step 2. 1) Two brown wires crimped into an eyelug under a screw on the deckplate near the blower duct (underside of the deckplate). If this wire is taped off, reconnect. 2) A brown wire with a slip on connector connects to a ground test point . on the formatter PCBA. If this wire is taped off, reconnect. ORIGINATOR: Norm Jones MAGNETIC TAPE I/O-CIPHER-F880,MTS-------------------FIB024 Pg001 FIB 00025 01/29/91 *** MTS runs slow (start/stop mode) after replacing main logic PCBA. *** SYMPTOM/TEXT: After replacing the main logic PCBA (MM630055) in a MTS tape drive connected to an 8000 system via a TDP controller, the tape back-up runs excessively slow. The tape drive will pass diagnostics, but always runs in start/stop mode. FIX: There are two versions of the MM630055 logic board currently being supplied to the field: 160106-001 - Old Style, contains 4 proms, this board should be compatible with all systems. 960757-001 - New Style, contains 3 proms. There are two sets of prom chips available for this board. The latest revision proms (962489-013,-014,-015) are currently being installed at the repair center and will cause the symptoms described above when connected to a TDP controller, but will work fine when connected to a BMTC controller. A slightly older revision of proms (961634-004, -005,-006) can be used to replace the above proms and will work with either the TDP or BMTC controller; use part numbers MM638095, MM638096, MM638097 when ordering. These two sets of proms are interchangable. Note: You cannot exchange proms between Old style and New style logic boards. Be aware that there are some old style boards (160106-001) in the field that have been upgraded and contain only 3 proms, these will have a high revision level such as 1C.

There are two different versions of the SCSI Conversion kit. One is for the GPx 40 system, it uses a 'Single Ended' interface (CSC 100; PN 400494-015). The other is for the GPx 70 systems, it uses a 'Differential' interface (CSC 200; PN 400494-016). Each kit should contain a manual with logics and interfacing information. We add one single sheet of paper that has the MAI switch settings. This Field Bulletin will provide information that may appear confusing in the manual. POWER: Power for the SCSI interface will be provided by the MTS through an internal tap. On NEW MTS units, this tap is already provided with a connector plug that is tie-wrapped up in the cable harness. Other units will require the use of the supplied 'line tap connectors' that will attach to: MTS MAIN HARNESS SCSI POWER CONNECTION (J4) P3-10 WHITE WIRE P3-9 (or P3-7) BLACK WIRE NOTE: The line tap connectors are like those used to connect trailer tail lights to your car. SWITCH SETTINGS: There are three (3) switches on the CSC 200 PCBA. Two of the switches are next to the LED's viewed through a slot in the metal cover. The other is at position '6T', the metal cover must be opened to see this switch. The CSC 100 has the same switch settings with the exception of switch 'T6', instead it has jumper 'W7'.
