F030 real-time clock failure

F030 real-time clock failure

Post by Andrew Giddin » Wed, 04 Feb 1998 04:00:00


Yet another plea for assistance, I'm afraid.  The real-time clock in my
Falcon seems to have packed up - every time I switch it on it thinks it's
31:63:62 on the 31/15/2107!!!  It also resets sometimes whilst the machine is
turned on (when programs end, it seems).  Infuriating!

My instinct is that the battery's dead, but I'd have thought then the clock
would run fine whilst the machine is running.  No-one I've spoken to seems
sure about this.  Has anyone seen this before? Is it definitely the hardware?
(Should I be using anything other than the COPS or XCONTROL to reset the
clock?)  Someone pointed me to the NVRAM, but all the settings such as
monitor type have been fine all the time. Is the NVRAM in the same chip as
the clock?  Is it a chip I need to replace?

Also, the doc for a clock program hinted that there're two system clocks -
the keyboard clock and the GEMDOS clock?  I know I'm easily confused, but
this really puzzled me!  Which one should I be setting?  Which one of these
keeps its time when the machine's off, or is it something else?  If so, how
do I ensure that when I set the clock, the new time is kept `permanently'?

I've even tried going back to the Forget-me-Clock II real-time clock cartidge
I used with my STE, but although the config program is reading it fine, it
won't set the Falcon's clock... :(

Help please!

(By mail, please - my phone bill won't allow me to check newsgroups very
often :(  )




1. 'SMART WATCH' Real-Time Clock - (nf)

Well, there's another good product here in germany:

the HEISE VERLAG (Hannover) (they bring out the c't magazine) is marketing
a battery-buffered clock that fit under EVERY ROM on EVERY SYSTEM. Soft-
ware is included for the ATARI ST series. It also works in the 1040 case !!!

You can use this clock on every rom or ram socket. (It's very easy to use:
simply access *for three times* the LAST ADDRESS on that ROM - then you can
access the clock ...)

The price ? 109.- DM ~~ $ 50
