Has anyone with a 2000 had problems with his/her real-time clock?
I seem to have run into a problem. Everything on the system seems
to work, but the clock. If i fire up the clock program, the time
just says the time when I turned on the machine. If I click on
an icon, wait a long time (1 minute) and click on it again, the
program runs, as if I did a double click. That's why I think it's
the clock. Also the screen blanker does not work anymore.
If anyone has a clue as to the whereabouts of the clock, or how
much it will cost me to fix it, or the possible causes of this type
of tragedy, I would really appreciate some input.
Thank you.

Re: .0 The Amiga's timers are located in the CIA chips. There are two CIA chips (the name stands for something like Complex Interface Adapter), one controls the parallel port and one controls the serial port. The CIA chips do seem to have a high failure rate. Since they are tied to the ports on the back of the compiler, they are somewhat prone to environmental damage (static, shorts from plugging and unplugging cords into the ports, ...). Replacement CIA chips are available. Previous notes describe cost and sources. Do both your serial and parallel ports work? | |||||

Re: .1
thanks a lot for the info Randy. i'll check the rest of the notes
for cia info.
the serial and parallel ports bothe seem to work ok, and the software
that i've run since the problem occurred seems to work fine too.
i guess dungeon master does not use the clock.
thanks again

| 2371.3 | CIA == 8520 | TLE::RMEYERS | Randy Meyers | Fri Mar 17 1989 13:38 | 3 |
Re: .2 By the way, the CIA chips are also called the 8520 chips. | |||||

an update on the clock problem.
i went out and bought a new 8520 chip, and opened up my box to find...
not one, but two 8520's inside. that was news to me. by trial and
error, i found that the chip on the right (as you look at your 2000) is
the one that had the problem. it was very easy to replace.
i hope this will help someone else in the future.
BTW the 8520 cost a mere $16.00.
thanks for your help
