I tried some searches, but are there MSX2 and higher computers made without a RP5C01 compatible clock chip on ports #B4-#B5?

As far as I know the clock chip is a mandatory part of the MSX2 standard (and up), and in its absence the MSX2 BIOS won’t even boot up.

wow thats fast thank you, thats good news...

There are rare cases where people have upgraded their MSX1 to MSX2 without installing a clock chip, by using a modified BIOS with the clock chip initialisation code bypassed.

Yes I am aware of that.

Are we sure that there is no MSX2 and 2+ that have been released at the MSX time without the RTC?

The RTC is fully part of the MSX2 standard, it is not even an option.
