Hyperion 512K+ Real time clock

Used clock integrated chip as below.

To activate the clock, I needed modify present board cause need some more control line for it.

Here is the board with clock chip.

To use this clock chip, it isn't easy with general way, finally my trick works to make it run.

Here is the working screen.

As you can see, it works as the No Slot Clock.

User can change time, and date as the same as the No Slot Clock.

But, Now it became Yes Slot Clock. :D

Work as two blocks 128KB.

Still fully compatible as the Saturn 128K. with first block.

And the other three 128KB blocks also ready to use.

I just add Battery holder for data backup for general SRAM(No clock function) chip.

Thanks;
