The chart below specifies the back-up time which may be expected for different quantities of memory. Memory Expected In K Bytes Stand-by Time __________________________ 64 : 3 1/2 Hr 128 : 3 Hr 196 : 2 3/4 Hr 256 : 2 1/2 Hr There are three factors which directly influence the amount of time the battery will refresh the memory boards. If a customer experiences a power failure and receives significantly less stand-by time than the above chart designates, these are the areas which should be checked. 1. The battery is of the lead-acid variety. Battery life is between 4 and 6 years. The battery's life is effected by temperature, number of charge- discarge cycles and the level to which the battery is allowed to discharge during each cycle. A healthy battery will have at least 2.0 volts open circuit voltage at each cell. 2. Different memory capacities will, of course, draw different currents. The D.C. current drawn by the different amounts of memory should be in the range of 1-2 amps D.C. The current should be measured at the battery terminal with a D.C. current meter if available. If the D.C. current is appreciably greater than 2.0 amps, then there is a problem with one of the memory boards. 3. Finally, there is relay circuitry built into the memory power supply which is supposed to open circuit the battery before it can discharge below about 10 volts. However, the relay will occasionally open circuit the battery prematurely. This problem is not likely to effect the expected stand-by time by more than 30 minutes. In addition, if the relay allows the battery to discharge well below 10 volts, the life of the battery will be significantly decreased. J. Van Oordt Calvin R. Davis 11-20-80 ORIGINATOR: J.

PART NUMBER DESCRIPTION MODEL NUMBER 906999-001 Lightning CPU 9153 906999-002 Lightning CPU plus 8-Way 9154 If this kit is to be installed in a 200/410 system containing a 1340 CPU, then a Model number T310 upgrade kit is a requirement prior to installation of this kit. The model T310 upgrade kit consists of only a 1345 backplane PCBA (903145-001, MM #831001). KIT INSTALLATION PROCEDURE: 1. The first step is to disconnect AC power from central cabinet assembly. 2. Remove rear panel to expose interior of cabinet. 3. Disconnect and remove CPU set from CPU card cage. 4. Install lightning CPU set,with the H.S. CPU (P/N 903068-001, MM #861010) in position J4 and the H.S. CPU Aux. (P/N 903070-001, MM #861020) in position J5 of the CPU card cage. (These positions are dedicated). 5. Disconnect and remove CPU power supply PCBA from CPU card cage. 6. Install CPU power supply PCBA (P/N 903288-001, MM #832010), in position J12 of CPU card cage. 7. For -002 versions, install 8-way controller PCBA, in the first available position, starting with J8. If a 4-way controller exists and is needed according to the system configuration it must be re-addressed as the second terminal controller and follow the 8-way in order. 8. Make any necessary adjustment to 36 amp power supply as follows: TEST POINTS VOLTAGE VARIANCE ADJUSTMENTS TP 1 - +12 Volts + .12 Volts None TP 2 - -15 Volts + .40 Volts None TP 3 - + 5 Volts + .10 Volts R28 TP 4 - Ground N/A N/A a) Adjust R28 to obtain +5 Volts + .10 Volts. (This is the only adjustable voltage on the power supply. b) Potentiometer R42 is used to adjust power fail detect, this is a factory only adjustment. The correct setting for power fail detect is: +5 Volts + 2.5 Volts at VAC 89 0 Volts at VAC 85 9. Reposition and fasten rear panel on central cabinet assembly, and reconnect AC power. 10. Run diagnostic tests as required to verify machine operation. NOTE: Schematics for the 36 amp supply are in the 1600 Service Manual Vol II.

This time delay is designed within the disc formatter to allow the disc drives to power up individually in sequence without putting any . excessive load on the power distribution. On systems with fixed disc, 200/210/ 410 this delay depends on the time the drive takes to start up and reach its operating speed. For Priam disc drives this time is approximately 50 seconds. Systems with Memorex drives it takes approximately 16 seconds. ORIGINATOR: R.

The Main Status byte contains the status of the hardware. The Auxiliary Status byte is software dependent and unique to the particular application program resident within the controller at the particular time the status is read. This document will be limited to a description of the Main Status byte only. MAIN AUXILIARY --------------- --------------- 7:6:5:4:3:2:1:0 7:6:5:4:3:2:1:0 STATUS BYTES The Main Status values differ between usage in "System Mode" and "Monitor Mode". "Monitor Mode" indicates that the IMLC is under PROM control. This is true before and during the time that the IMLC is being loaded. After the load is completed, the IMLC immediately enters "System Mode", and runs under IMLC 0S control. ********************** MONITOR MODE OF OPERATION ********************** SELF-TESTS To display the controller self-test status from Basic in console mode, enter the statement as follows: ENTER: OPEN(1,TRK=0)"I0" The above statement causes the controller to execute the Self-Test. In the event of a Self-Test failure, the status will be returned and displayed in hexadecimal as follows: ERROR 5 STS=FF C0. -- -- I I I *--> Auxiliary I *-----> Main The Self-Test Main Status codes are as follows: 80 - All self-tests completed successfully 82 - ROM checksum incorrect 84 - ROM's RAM is defective (BE7D-BFFF) 86 - Lower memory is defective (4000-7FFF) 88 - Upper memory is defective (8000-BFFF) 8C - CTC is defective 9C - PIO is defective 9E - ICOM channel control error A0 - ICOM channel data error A2 - XCOM channel control error A4 - XCOM channel data error D6 - DMA 1 block move error D8 - DMA 1 read error DA - DMA 1 write error E6 - DMA 2 block move error E8 - DMA 2 read error EA - DMA 2 write error CPU-BASIC FOUR-110,1600,200,210,310,410-------------FIB017 Pg001 F6 - DMA 3 block move error F8 - DMA 3 read error FA - DMA 3 write error Note that if the Main Status returned is hex 'FF', this indicates that interrupts are not being received from the controller. This indicates that the system sees the controller as totally non-functional. Also note that the Auxiliary Status byte has no meaning during self-test. The status bytes may also be displayed by the normal controller loading program "*LOAD" by making the following change to the existing program: 1) Enter: LOAD "*LOAD" 2) Enter: LIST 9120 (Should display [IF E9>0 THEN LET X9$="LOAD ...]) 3) Enter the following changes if not contained at end of STNO 9120: Enter: 9120:+" STATUS = "+HTA(BIN(TCB(3),2)) 4) Enter: SAVE The status will now be displayed any time an error occurs while the system is attempting to load the controller via *LOAD. ********************** SYSTEM MODE OF OPERATION *********************** Following the self-tests and loading by the CPU, the controller enters the System Mode of operation. The Main Status byte shown below is for reference only since it will not normally be returned to the operator. Rather, the software will convert the status into a Basic Error code for program handling and the appropriate error displayed to the operator will be the Basic error code. Refer to batch Emulator User's Guide, BFISD 5080, Appendix A, for a description of these error codes. 7:6:5:4:3:2:1:0 I I I I I I I I I I I I I I I *--> Abnormal condition - Error 99 in Basic, non-fatal I I I I I I *----> Illegal condition - note 1 I I I I I *------> Hardware busy - note 2 I I I I *--------> Overflow; command received while IMLC busy - note 1 I I I *----------> Not used I I *------------> Software busy - note 2 I *--------------> Attention (0) or DMA Completion (1) interrupt flag *----------------> Always 0 in System Mode (1 = Self-test/Monitor Mode) NOTES: 1) Fatal hardware or software error. 2) Error 0 in Basic returned if this bit is set for greater than 10 seconds; if error 0 is returned, the TCB(3) functions will not be valid.

Basic Four Model 6500 Magnetic Tape Drive Service Manuals BFC 8036 & 8036A are now incorrect (BFC 8036B is correct). Manual 8036A shows the correct switch settings for the on-line and off-line operation of the old controller and MTR (S1 closed, on-line; S1 open, diagnostic mode). On the new style controller the S1 switch position is exactly opposite. Controller and tape unit are on-line with S1 in the open position and are off-line with S1 closed. New style controllers at or above revision D are compatible with the magnetic tape streamer (MTS). S4 is used to designate that the attached device is a streamer. S4 is to be OPEN whenever an MTS drive is attached, whether on-line or off-line mode is selected. Be aware that when both the old and new style controllers are in on-line mode, the positions of switches S2,S3, and S5 through S8 are of no importance. However, these switches do become affected when the S1 switch of either controller is set for off-line mode. During off-line mode, these switches allow. certain off-line operations, depending on their settings as outlined below. MTR/MTS CONTROLLER SELF TEST The MTR/MTS controller board has a local self-test capability which verifies correct functionality of the tape interface.

The light will stay out until EOT and a subsequent automatic rewind. Then the light will go ON and the test will start over. This test will recycle 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 forard direction and switch 6 has no effect. Do not change switch positions 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 defects in the tape. The test light will momentarily go OUT, indicating a write gap. All normal operations of the controller with the CPU require that switch 1 be OPEN, or it will not respond to commands. ORIGINATOR: B.

The problem is rather rare, but can cause system halts, syatem hangs or hung terminals. It is due to a difference between the compiled code of programs compiled under BBII and programs compiled under level 3 or 4, and is apparently limited to programs containing a DEF$ function. If such a program is LOADed into memory and the a console DELETE is executed, a halt or hang can occur. This problem can be corrected by recompilation of the suspect program. Another symptom of the problem is that the system utility for renumbering programs fails on the com- piled code. A method for recompiling BASIC programs is as follows: First define a SERIAL work file for 1000 records and 132 bytes pre record. Name the file "SER001". (1) START a terminal with suficient memory pages to accomodate the program to be re-compiled. (2) LOAD the program. (3) In console mode, execute the following: OPEN(1)"SER001" (4) In console mode, execute the following: LOCK(1) (5) In console mode, LIST the program o "SER001" by typing: LIST(1) (the list make take several seconds - wait for the > ) (6) Close "SER001" by typing: CLOSE(1) (7) Re-START the terminal with the same number of pages used in step (1). (8) OPEN "SER001" again by typing: OPEN "SER001" (9) LOCK "SER001" by typing: LOCK(1) (10) Merge "SER001" into memory by typing: MERGE(1) (the merge may take several seconds and may end with an ERROR 21) (11) Close "SER001" by typing: CLOSE(1) (12) SAVE the program now in memory to it's original name. Repeat the above process for each program that has been translated from a BBI or BBII system AND that contains a DEF$ function.

PROBLEM SOLUTION: Although the manufacturer is currently in the process of developing an engineering change to resolve the problems, this alert is written to inform you of the probable cause of said problems and of the actions which may be taken to help resolve them. This alert will be revised to detail the changes required when the corrective ECN is released.. Problem : 36 Amp Power Supply appears to cause halts. Cause : Noise cannot properly be routed to earth ground Recommendation : Note 1, Note 6. Problem : Non-Lightning CPU appears to cause halts. Cause : Peripheral cable noise is not properly grounded.. Recommendation : Note 2, Note 7. Problem : Operation of some peripherals cause halts/hangs Cause : Peripheral cable noise is not properly grounded.. Recommendation : Note 2, Note 3. Problem : System halts/hangs at specific times of day. Cause : Noise generated by equipment within the building is not properly routed to earth ground. Recommendation : Note 1. Problem : System halts/hangs on specific jobs. Cause : Disk system problem and peripheral noise. Recommendation : Note 2, Note 4. Problem : System halts/hangs when certain devices are connected. Cause : Chassis ground noise is not properly grounded. Recommendation : Note 1, Note 2, Note 3. Problem : System halts/hangs when chassis or control panel is touched. Cause : Static is not properly being discharged to earth ground. Recommendation : Note 5. Problem : Disk hangs, error 3 and/or 4 occurs. Cause : Disk power supply cannot tolerate noise. Recommendation : Note 1, Note 4. NOTE 1: As this system appears to be intolerant of AC line problems (voltage and noise problems), ensure that the AC power is clean (power monitors will help identify problems). Proper line isolation (dedicated circuit) and good earth grounding are critical items of concern. NOTE 2: Peripheral devices can and do present the biggest ESD problem for the . system. Cables should be to MBF specifications and all shields properly secured at both ends of the cable. Problems such as earth ground potential differences caused by this action are power related and must. be resolved by the customer. CPU-BASIC FOUR-110,1600,200,210,310,410-------------FIB045 Pg001 ESD introduced at the peripheral may well be environmental in nature. Areas susceptible to static build-up should be treated with an anti- static spray. Customers should also be aware that handling static generating materials such as plastic bags may require special anti- static measures to ensure the build-up is not discharged into the system via the peripheral. NOTE 3: Peripheral chassis ground and logic ground must not be a common point. Most devices allow re-strapping to meet this requirement. Those that do not must be addressed by the customer to his supplier. NOTE 4: Excessive disk re-tries may make the system appear to hang. If a hang condition exists (especially when the same job is being run) the disk should be checked (using zero re-tries) to verify its integrity. Re- formatting may be called for. NOTE 5: Problems encountered due to physical contact with the system chassis or control panel should be resolved with ESD kit MM995501 (see MSA #388). Systems experiencing major ESD problems from peripherals may also be helped by this kit. NOTE 6: Some cases have been resolved by installing old style power supply (MM831041). NOTE 7: Interchanging CPU set PCBA's position in backplane and moving T0 and T1 to 8-way (if there is room) has, in some cases, resolved this problem. ORIGINATOR: J.
