CFTBL displaying incorrect time...

The clock is keeping time perfectly. When I go into the menu to set the
time, it shows the correct time. However, when I set it to display the
time, it shows the wrong time. Odd... Any ideas?

Batteries are new, contacts are clean, I checked all voltages at RAM and
CPU. Rev3 of ROM.

thanks!

If it's off by exactly 12 hours, is it set to a different time style?
I thought you could set that in one of the menus?

No, it's displaying a time from approx 7 hours and 29 minutes ago. When I
display the time, it will never change on the display, but in the setup menu
it keeps time perfectly.

Go in and delete the custom message some jackass put in that looks like the
time / date?

(I'd also pull the batteries for a few minutes to reset everything.)

Reset everything, pull the batteries, factory defaulted everything. No
custom message.... Still bad... Now the time being displayed is from 39
minutes ago...

And the time never changes. i.e. it doesn't tick up by the minute,
right?
Are you using a Rottendog MPU replacement?
Do you have a logic probe and know how to use one?

Here is more detail...

The time shown on the display is the exact same time as shown in the setup
menu under:
"Histograms->Bookkeeping->timestamps->Last game start" and it follows the
last game start every time.

The value under "Bookeeping->timestamps->current time" is accurate

I lost my probe, but have a pulser and oscilloscope. Yes I know how to use
it. Any ideas would be welcome.

thanks!

*HUH*!! Hmmm.... Here's a shot in the dark -- have you tried re-seating
the WPC ASIC on the CPU board? (Complete shot in the dark; sometimes
having it mis-seated can cause all kinds of crazy stuff to happen!)

No, don't have a chip puller. I need to pick one up...

Ya...don't try to re-seat it without a PLCC puller.
It think that's a good thing to try.

So the time never changes...
You are =not= using a Rottendog replacement (Jim's board doesn't keep
real time)...

The reason I asked about the probe is that there is a small
cylindrical crystal that vibrates at 32KHz, and in concert with the
4584 (U21) right next to it, provides a "tick" to the ASIC that the
ASIC uses to keep pseudo-realtime.

Measure at pin 70 of the ASIC or, more easily, at pin 12 of the 4584.

All boards are original. Not sure if you saw my last post, but the time
being displayed is the value in the "last game start" register. Not sure
how it reads those registers, but it appears that it is reading the wrong
register to display the time.

I will check the freq of the crystal now...

Checked the freq on pin 12 of the 4584 and it's a square wave with a pulse
width of just a hair over 30 microseconds (analog scope sorry). Looks like
the freq is right on the money...

HI Rich,

Yes, I saw that post. I just don't think it very probable that it's
reading the wrong register. It's more probable that the "last game
start" register is being filled with the same time.

Thinking...

I have a similar problem. Please note new to SS/DMD pins. Heres what
happens on my game. Clock never seemed to display right time after
setting it in menu. I can set the time/date and it will be
correct...play some games...turn it off. Next time I play it be a day
or 2 later what-have-you, when I turn it on the time/date will be from
where it last was when I turned it off. If I play some games, the
date will catch up and be correct, but the time would always be
wrong.

I got the game in March I believe it was, and seller I got it from
said batteries were new and installed in Jan of this year....so when I
ran into this problem I checked the batteries...which expired in Jan
of 2008, and one was dead when testing....thank you seller. I cleaned
the battery holder contacts and installed new batteries. So now it's
still the same symptoms, but the clock WILL catch up AFTER turning on
and playing some games, but still be about 10 minutes behind and then
not move any more while playing game.

I am going to install a remote battery pack and see if that clears it
up. If not, I was told that it is most likely the crystal for the
real time clock(which are very fragile I believe)and if that doesn't
correct it, it could be one of the chips which is not very likely
though. Also, Clive had wrote me an e-mail in which he said he's run
into some boards from Creeches that had the same problem.
Interesting to see what you come up with. Please post if you find the
solution. Good luck.

The "last game start" is accurate as to the time I started the last game.

Check this register in the setup menu:

Bookkeeping-> Time-Stamps -> Last Game Start. I would be willing to bet
that this time matches the time on the display. What version ROM you
running?

Just checked it out. Here is my info..

Display shows: 20018 REV P-3 Sound REV SY2.46 P-1

Game displayed time/date of Oct. 5 7:07pm...which was last time I
played it.

Then as you suggested went to Bookeeping>Time-Stamp->Last Game Start
and time/date did match what displayed.(which was from last time I
played) BUT, I also noticed that in the current time display in
bookeeping the TIME and DATE WAS CORRECT and RUNNING! Does any of
this tell you something that could be wrong w/my games as far as
displaying the correct time/date? I was just going to NOT display
time/date, but it's been haunting me why it doesn't work. I have to
go to work, so I won't be back on RGP till real early Sun. morning,
or later in the day. Thanks for any info.

Your symptoms are identical to mine. I am willing to bet that the program
is reading the "Last game start" register and displaying it. I am upgrading
to L-4 of the ROM (even though the release notes do not comment on this) and
will post the results here as soon as John sends me the ROM.

Any chance one of the batteries is installed backwards?

Thanks for all the advice everyone. I would be willing to bet that this a
L-3 ROM issue. I won't know until I get my L-4 ROM to test. I would
further venture a guess that the instruction set is reading the value stored
in the "last game start" register (B.6 07) as opposed to the "Current Time"
register (B.6 01) It's been 17 years since I got my EE, and I don't know
enough about how the MPU reads the registers, so it's a guess at best.

This thing keeps perfect time as shown in B.6 01, and only displays the
wrong value (which is from B.6 07). It can't be a clocking issue, and logic
is leading me to a code issue. Anyone have L-3 ROM to doublecheck?
