Subject: A5000 help

I know its not bbc related, but i have bought an A5000, but the start up
checks come up bad, but i cant work out the binary to hex conversion

here is a page from the net about fault codes :

The power on self test was introduced with RISC OS 3.0 and later
versions of the OS. On power up your machine checks the hardware for
physical faults before letting you use it, hopefully signalling
important errors to you before further hardware damage can result.

The purple screen at power on indicates that the self-test has begun. A
brief ROM, RAM, VIDC and IOC test is performed and then the screen
colour changes to blue and a limited memory test [1] is performed, along
with a second test of the VIDC and IOC. When the screen returns to
purple, the machine is testing for an ARM3 (or better). At the end of
this sequence the screen colour is set to green (for pass) or red (for
fail). If the tests have all passed then the machine starts to boot and
the RISC OS 3 welco
me screen is displayed.

If any test fails, the screen will remain red and the disc drive light
will blink a fault code. A short flash is used to indicate a binary '0'
and a long flash indicates a binary '1'. The bits are grouped into eight
nybbles (blocks of four bits) with the most significant bit first.

The lowest seven bits are a status word. The meaning of each bit is
given below in hex :- 

00000001   Self-test due to power on
00000002   Self-test due to interface hardware
00000004   Self-test due to test link
00000008   Long memory test performed
00000010   ARM ID detected (ARM 3 fitted for non-RiscPC hardware)
00000020   Long memory test disabled
00000040   PC-style IO world detected
00000080   VRAM detected

Bits 8-31 indicate the fault code and are described below. Not all the
bits are used. If the code is marked as reserved on the RiscPC this
means that error number is currently either unassigned or it's meaning
on older hardware is no longer sensible for the newer machines (and thus
it's meaning may be reassigned on the newer versions of the OS.)

00000100   CMOS RAM checksum error
00000200   ROM failed checksum test
00000400   MEMC CAM mapping failed (A reserved code on the RiscPC)
00000800   MEMC protection failed (A reserved code on the RiscPC)
00001000   (A reserved code on the RiscPC)
00002000   (A reserved code on the RiscPC)
00004000   VIDC Virq (video interrupt) timing failed
00008000   VIDC Sirq (sound interrupt) timing failed
00010000   CMOS unreadable
00020000   RAM control line failure
00040000   Long RAM test failure
00080000   (A reserved code on the RiscPC)

the error codes i get are
s s s s
s s s s
s s s s
s s s L
s s s s
s s s s
s L s L
L s s L

Thanks for your time
