> descaling /020 and /040 boards to /00 single core CPU high freq.

While technically possible for A-Eon to have CyrusPlus boards with P5010 manufactured (which would make it /10, not /00), it wouldn't really make sense for the following reasons:
- The P5010 has been EOL'ed (last delivery 09/2020) just like the P5020.
- The cost saving compared to the P5020 is tiny in relation to the overall board price, and Linux would noticably suffer from running everything on a single core.
- The P5010 does not clock any higher than the P5020. In fact, the P5040 clocks higher than both.

X1000 and X5000 (and A1222) being at least dual-core may have more reasons than just the announced multicore support for OS4 (and better Linux performance).

As has been established, Blackbird would be way better suited than Talos II, and spec-wise it would make at least as much sense for MorphOS/OS4 as the quad-G5 and the X5000/40, and even more sense with regard to the POWER9's much higher single-core performance than anything MorphOS/OS4 currently run natively on.
If it wasn't for the extreme price increase over the years...
