Re: Royal Mail Delays
To be fair to them - I've had something stuck at "langley" and it was down to customs check delays - so although it appeared to indicate RM had my parcel - it had not been officially released to them. I hate the fact that the tracking from either side doesn't tell you what our lovely HMRC ...
Re: RTC Query
esp32_ser.jpgHey Pr0f ; Someone was way ahead of me :D Anyway its great to try to program such nice connection. And one can make your own preferences. I do like the lilygo products though - and there is probably a lot more this could potentially offer - would be interesting to see how well it works...
Re: RTC Query
I wonder if those serial network modems would provide time?

Re: RTC Query
The other approach would be to use an RTC chip that actually does have a "seconds counter" and just disable the ZX8302 whenever a read access to those RTC addresses is made - and provide the data from the seconds counter RTC chip instead. No I2C needed - as the code in the QL is already se...
Re: RTC Query
The Minerva MKII has I2C interface and does have an on board I2C RTC and RAM chip.
There is a project ongoing on here to recreate the PCB for that - the code is already in the Minerva ROM

Re: Today I Received...
I rescued a BBC Basic manual from a school I worked out - was for RM machines - but it contains the full list of commands. Also since picked up some books on the Z88 that cover BBC Basic - It's a good version of the language.

Re: Switching Regulator?
The only issue I could see is that some of the older switching regulator circuits operate in the lower frequencies and might produce radiated interference that could affect the microdrives, but more modern designs use very high KHz or even MHz range and so this is less likely going to be an issue. A...
