Yes, the hd6301's reset doesn't clear the internal ram. So next time the 
hd6301 starts, the previous values are still there and the clock remains 
correct. Which is quite normal, considering the ikbd's clock can be used 
as a persistent clock between full reset of the ST. It doesn't have a 
battery, so it won't keep its values after a power down, but it will 
keep its values after reset.
