How many of the systems with RTC support have y2k or similar bugs, whether currently active or coming up soon?

Does the physical RTC module offer anything over the NTP time off the network?

None off the top of my head. In all likelihood they may just 'wrap' around to the wrong century but I've yet to see that on a MiSTer core. It would depend entirely on how the hardware/software implemented dates.

Retains the time when the MiSTer is not networked. That's all.

When you print DATE$ with the PC-88, it shows the wrong year but correct month and day. I suspect that may be a Y2K issue, but I haven't tried to set the date to < 2000 to verify.

I seem to remember that the Commodore datasette has an internal ADC and outputs (or receives) a digital signal from the user port. It is possible to connect it to the MiSTer user port (obviously an adapter would be needed) to read the digital signals and also control the motor?

I think the appropriate thread is this one: viewtopic.php?t=4848

Short answer: not possible yet because no one has made it yet, but feasible.

This is an incredibly late reply, but the RTC means that Linux boots up with the correct network time instantly. You don't have to wait for the time to appear in the title bar before launching RTC-aware cores. I think it shortens my cold boot time by about ten seconds.

You do have to set the RTC once per battery, but it's not difficult.

Dunno nothin' about Y2K bugs on old computers. I can say that the systems I've tried (Amiga, Archimedes, and AO486) seem to understand that it's 2022 just fine, at least at a system level. Individual programs could have all kinds of stupidities.

So your NAS connects right away but NTP takes longer?

The NAS takes like +1 or +2 seconds after I see the Mister menu; by the time I can browse anything, it's up. NTP usually takes about ten seconds to synchronize.

Sord M5 now has ADC support, which is a nice little cherry on top of that core.

Thanks, I've also updated the status of molekula's other core, the MSX1, which I believe is official for quite some time now and was still listed as unofficial.
