going out on a limb and praying the schematic is correct

[MrDEB]

my Christmas 2025 project I had to redo (see posthttps://www.electro-tech-online.com/threads/using-a-rtc-in-sf-basic.166376/post-1460947
and have yet to get a 74hc595 to work properly but it should work as per schematic.
Am aware this is asking for more problems but hopefully not.

I had to do something vaguely similar to animate the lights on an old signalling panel for the local train museum - used a slightly different approach re pins 10 and 13 (MR & OE).

Perhaps temporarily try the different connection set up and pump some data through them to see if anything happens.
