| I read that the seller does not post to Germany... -Did Apollo-team got a bulk batch and did not give a 5 star rating?
-Is it because that those are timed in ausie-time-zone?
(Hehehe)

| Yes, but you charge 55 euros to post to Australia.
I thought that was a bit too much.
I had a look at the RTC module you sell and it has the same part number, so alls good.Thanks

| I bought one of these and plugged it into the RTC header on my Icedrake, but it doesn't seem to work. The date/time is not being saved and resets to 01/01/1988 on restart. Any tips?

same problem here, i bought one along with the ICEDRAKE and it doesn't keep the date.
moreover almost all the WHLOAD preloaded games have problems.

| You'll need correct I2Clock-driver or SAGA 2.8 Package to save/load time. Also you have to remove "setclock" from Startup-Sequence and add "i2clock" instead.

| Thanks for the reply. I have i2c.library in Libs:, i2c.hidd in Devs:Drivers (both as provided in the ApolloOS_R81.img file), and the relevant lines in my startup-sequence are now: C:I2Clock >NIL: LOAD CHIP=DS1307
;C:SetClock >NIL: LOAD The date/time is still not being saved.

| DS3107 is wrong for Icedrake.... Try I2CClock scan in Shell to find the right chip or I2Clock show to read stored date & time.... But ApolloOS seems to have a bug. Sometimes setting the clock works but most of the time it won't work....

| i bought a CF card with ApolloOS along with the Icedrake, i thought that this would mean that it will work out of the box without any configuration, do I have t set the startup sequence that way too?
