EDIT: Ignore all of this. Apologies. It's my patch wires. they're slightly too thing so I'm getting intermittent connection with various random ones of them.

I'll get some more...

I can't make any sense of this any more - I must have something wrong (again). I am checking UD9 which is marked as 901465-03 and the results are changing every time I run the sketch....this cannot be right.

I have %v (measured as 4.9V) connected to pin 24 and pins 20 and 12 connect to GND.

All the address pins and the ouput pins are connected as per the code in post 509.

Example run (first few lines) of UD9:

PKK.IAH_.@IHA.@I
HA.IPA.@IHA.HOP.
IPA.@MHA.HOP.@OW
L..UAAPALMHE.@OP
..PRCSS.PHC[...P
CCKRB.KJ.PCPC...
LME..UTMPMLE..PE
TMD.DETMEE.LMT$T
PAQAH.HKP.IHPQP.
@IH.HIP.IQPPQP.@
ON..DOWLD..OO..P

Next example run of UD9 with nothing changed...

PII.IAHYA@HHA.@I
HA.IPA.@HIP.HIP.
IPA.@IHA.@IP.@KS
A..UAAPA.@MA.@OP
C.RRCSS....P...P
BBKRB.KJC..[C...
.MA..UPM.MHE..PE
DMD.DETMME$LMT$T
HAQAH.HIPQP`PQP.
HIP.HIP.QP.@QP.@
FN..DOWNO..TO..T

Is there anything obvious that I'm doing wrong?

Colin.
