At the risk of bringing up the subject of IIC_Control again I recently made the
following observation:

Using the call with the previously mentioned parameters (I do not intend to post
these) I managed to get my A5000 real time clock to stop counting when the power is
off. It would power on with the same time it had when powered off. Is there a software
fix for this? I fiddled around with further calls to no effect. At lease this call
didn't kill my machine completely. I did have to desolder the battery to restore
the real time clock to a normal state.

Is there a software fix for this? Where can I obtain the data sheet for the
real time / cmos ram device (who is it made by?). 

I would have thought that the newer machines might not suffer from this problem.
An A3010 in Dixons suffered more severe symtoms though I didn't have the operrtunity
to look at it in detail.
