*13 Non-volatile SRAM Tests the integrity of the contents of battery-backed SRAM.
Detects loss of power to the SRAM.
*14
Digital IF Control
Tests the operation of the LAN circuitry.
15
CPU Support Circuitry
Tests various circuits that are required for the main processor
(68030) to operate. Tests timers and interrupts. Attempts to
clear and disable all interrupts. Tests each interrupt signal to
the 68030 to make sure that none of them are asserted.
16 Analog Bus Tests the analog bus control circuitry and +5 V and EPROM Vpp
on the CPU board.
17 Real Time Clock Tests the real time clock and tries to access registers on the chip.
*18 Front Panel Interface Tests the front panel control processor. Tries to access registers
on the chip.
*19 Floppy Disk Controller Tests the 3.5" internal disk controller portion of the Super I/O
chip. Tries to access registers on the chip. Writes commands to
the chip, and verifies correct response. Also steps the floppy disk
drive's head from track 0 to 9, and back to 0, to test the ability to
find track 0.
*20 GPIB Interface Tests the GPIB interface circuitry. Tries to access registers on
the chip. Writes commands to the chip, and verifies correct
response.
*21 RS-232 Interface Tests the RS-232 portion of the Super I/O chip. Tries to access
registers on the chip. Checks for missing clock input to the chip.
*22 DIN Keyboard Interface Tests the DIN keyboard control portion of the Super I/O. Tries to
access registers on the chip.
*23 Centronics Interface Tests the Centronics interface portion of the Super I/O.
24 Front Panel Key Prompts user to press any keys and displays information on the
key pressed. Press three times to exit.
25 Erase Non-Volatile SRAM Tests all locations of battery-backed SRAM by writing zeroes.
This erases existing data. Wait 30 seconds, then cycle power.
26 Source PLL Lock Not implemented.
27 X External Detector ID Not implemented.
28 Y External Detector ID Not implemented.
29 RS-232 Port Prompts user to connect a printer or terminal, and then sends
characters to the port.
30 Centronics Port Prompts user to connect a printer, and then sends characters to
the port.
* Denotes a test run during power-up.
