5.10 POWER SUPPLY - H7865 5.10.1 OPERATION The H7865 power suppl~ is a sinsle endedfswitch t~pe, re~ulated AC-DC converter circuit. It utilizes a uni-directional transformer in a half wave transformer coupled mode. The unit operates at a constant freQuenc~ and re~ulation is achieved b~ pulse width modulation of the inverter primar~ current conduction time. Primar~ ener~~ storase is in the input filter capacitors at approximatel~ 300V DC.
5.10.6 INRUSH CURRENT At the first application of input voltase to the power suppl~, the stated surSe current ma~ be reached for 1/2 cycle of the input line. Followins that surSe, there will be repetitive peaks of exponentiallY deca~ins amplitude for UP to 10 or more c~cles of the line until steadY state operation is reached. 128V AC: 70Amps (peak) 256V AC: 70Amps (peak) 5.10.7 OVERLOAD PROTECTION 5.10.7.1 An externall~ accessible circuit breaker is provided to protect the output wirins.

7.0 MICRO DIAGNOSTICS OVERALL MICROCODE STRATEGY The VS100 microcode is defined as the 16.0 kilobyte powerup/diasnostic packaSe, implemented in Motorola 68000 assembly lan~uase, and resides in read-onl~ m~mor~ on the Display Processor Module. The microcode is responsible for down-Ioadins the displa~ fi~mware, but is otherwise invisible to the host. Host (VAX-l1) diaSnostics are the property of the Macro Dia~nostic packase, but may call the Micro Diagnostics via the Reset function.
7.0.1 POWERUP SELF-TEST Tests occur in order of increasins lo~ic complexit~, in order to maximise error detection and minimise the chance of a catastrophic s~stem failure. The 68000 remains at prioritw level seven (all maskable interrupts disabled) until all liD control chips· have been tested and initialised. At this point, the priQrit~ level is lowered to zero (all maskable interrupts enabled)+ The Power~p code should run less than twenty seconds; the expected cold-start warm-up time for the monitor.
Two checkerboard test patterns ($55 and tAA) are used, first for b~te path immediate data and next for lonSword path immediate data, usin~ reSister dO. Once dO has been verified for immediate addressinS, it is reloaded with the first checkerboard pattern, $55555555. This pattern is then cascaded throu~h all eiSht data re~isters (dO-d7) and all seven address reSisters (aO-a6). The routine is then repeated with dO initialised to the second checker-board pattern, $AAAAAAAA.
PROGRAM MEMORY 7.0.5 A cursory memory te$t is performed, usin~ 32-bit lonsword instructions. The test is in three basic sections: I. 2. 3. Clear proSram memor~ (wri~e all zeroes). This performs an initial check on continuity of memor~ addressins. Restart at the be~innins of memory. Read the current lonSword for all zeroes, write all ones, read for all ones and pro~ress. to the next lon~word until end of memor~.
7.0.8 TABLET PORT Internal loop-back mode is set on the Tablet USART, and the same scheme used to test the CRTC Cursor Resister is implemented here on the data holdins re~ister. The internal loop-back scheme reGuires that the mode re~isters be set UP for normal operations, in order to test the USART as it would normall~ be used.
7.0.10 FIBRE OPTICS ELECTRICAL LOOP-BACK The Fibre Control Register is set for Electrical LoopBack Mode, and two checkerboard patterns ($5555 and SAAAA) are then written to the Host Control and Status Re~ister individually. After writing each pattern, NXM is checked for error status on the packet. If NXM is oka~, then the pattern is read back from the loop-back address. If the packet returns bad information, the data will be either all ones or all zeroes.
7.0.14 KEYBOARD SELF-TEST A reauest for the keYboard's hardware ID times out after If the ID is received, we then call the keyboard's self-test. It is necessary to call the Self-Test a~ain at this point, as the results the previous Self-Test could not be interpreted b~ the uninitialised 68000. The results of the current test are reported to the Keyboard LED's, and to the 68000 via the followin~ four-b~te messa~e: 1 second.
7.1 IDLE LOOP After successful completion of the Powerup code, the 68000 continuouslY loops on a modified version of the same code until the user either lo~s in or enters Maintenance Mode. If Idle Loop fails a test, it does not do an~ more testins until the next pass. All errors are lo~~ed to the host, but onl~ the first error detected is reported to the Mother Board and Keyboard LED's. The followinS tests are executed durin~ Idle Self-Test: 1. 2. 3. 4. 5. 6. 7.
7.2 COMMAND LOOP The host this point. 1. 2. 3. 4. The ma~ followin~ reauest the VS100 to perform WGA commands at commands are defined at microcode level: Reset (~o to Idle Loop via Powerup diasnostics) Send_Command_Packet (includes Move_Object and Report_Status Commands) Start_Displa~_Firmware (transfers control to the displa~ firmware) Init (initialise CSR's and ~o to command loop) Init initialises the Control/Status 1• 2. 3. 4. 5. 7. 6. 8.
7.3 MAINTENANCE MODE Several tests are available to test the input/outPut devices, as well as a special test for the fibre link. All tests in Maintenance Mode reQuire a human interface.

For future adaptabilit~ to 16-button pucks, a decimal conversion routine is used to report the button number.
EXCEPTIONS & INTERRUPTS All two-hundred fift~-six 68000 interrupts and exceptions are suPPorted b~ the microcode, whether or not they can be expected to occur. The 68000 provides two kinds of interrupts; Auto-Vectored and Device-Vectored. The VS100 utilises the Auto-Vector system. All unimplemented interrupts and exceptions result in the ~eneration of an error code/messase.
AUTO-VECTOR INTERRUPTS Seven level$ of interrupts are available on the 68000, in increasins level of priorit~. The hiShest level of interrupt is nonmaskable.
7.5 ERROR REPORTING All dia~nostics at all levels of microcode attempt to report errors in each of three wa~s: i. 2. 3. Error code to Mother Board LED's code to LK201 Ke~board LED's Error code to Host's Interrupt Reason E~ror Re~ister (CSR il) The error code is a n~bble (4 bits) code identifyin~ the test that failed. The code is the same for all three error code output forms. POWERUP: ~reen led off, test. in LEDS. Code set in advance of test.

7.6 MANUFACTURING MODE Manufacturin~ Mode is entered upon powerup when a Jumper is in place next to the Mother Board LED's. In this mode, loop-back connectors are used at the ke~board and tablet ports for special tests that are available ONLY when the Jumper is in place and are executed in place of the normal I/O self-tests. At the end of the Powerup SelfTest, the microcode Jumps back to a location in ROM (to be determined) and executes the entire self-test. This c~cle continues indefinitelw.
