Hi Peter,
Personally, as I have my name down for a QIMSI when available, I’d be very happy to have one with a RTC.
But I appreciate that without other interest it’s not going to be viable for you
Many thanks

Have I2C pins and support for read and write will be a good thing.
As a first step, I think is not necesary to have the RTC or support for it in ROM, if you add the minimum instructions to manage I2C from basic, later is possible to add a program on boot file that read the RTC and update the QL clock, and there is very cheap i2c RTC board in AliExpress and Amazon (less than 1£) that you can connect to the qimsi, PCF8593, DS1302 and others...
I only say this for your consideration if this is less work to you or easy to implement.
