Убрать Even M1 в желтом скорпе?

[null_device]

Insult Megademo also appears to be broken here (Scorpion ZS 256 Turbo+ ... no idea what fix he used)

In addition, there are hardware compatibility issues. Many demos cannot work adequately due to the smaller number of bars in the interrupt. Everything hangs, because The demo is designed for 128K Pentagon (in non-turbo mode). Or the inclusion of a turbo, there are problems with multicolor, due to the fact that the scan of the scorpion screen does not fall into the standard of both the branded zx128K and its clone pentagon128K.
Again: the “green” board of the scorpion has a slightly different circuit design and screen drawing compared to the “yellow” board, even with the “turbo” expansion (time components).
It was misled by green textolite. However, I would look for the "errors" that are characteristic of re-printing PCBs.

In some cases, performance under a scorpion is nothing more than a compromise.
The demo "insult" with the pentagon patch has been tried both?
