Re: Clock Card?

Yes, I did. I tried ProDOS users.disk and it claims there is no
time or date. I tried reading the eprom, however I am not sure
if I should read C400 or CC00. They don't display the same
info. It is a 2764 which is I believe 8k so I'm not sure how that
would read since $100 is all that will fit in the slot memory.
How do I find out where the firmware is loading into RAM?
You would think just about any clock software would find it.
ThunderClock software searches the slots, finds none. NSC
looks for it and finds none of course since it isn't looking in a
slot at all. ProDOS seems to find nothing. I don't know what to
try next.


The ThunderClock doesn't use a 6821 but the Timemaster II HO does
so it's software is a possibility. If you don't have that software
handy, you can find it at  http://www3.telus.net/waynes/time2_h.o.

As for ProDOS reading the time on it, I can think of several reasons
it might not.
It could have been made before ProDOS.
Some cards required a patch to ProDOS before it could read them.
Did you have a battery in the card when you tried checking the time?

A 2764 is a really large EPROM for a clock card. Even my Corvus
Systems clock card which has the time setting utility on the EPROM
only uses a 2732.
