ZX Evolution + MultiSound + VDAC2 + эмулятор КР1818ВГ93, сборка устройств клона Sinclair ZX Spectrum

In this video, I am assembling a KR1818VG93 (MB8877) floppy disk controller emulator, since it is practically impossible to buy a working controller today. Everything that is sold on various sites is re-marked chips, sometimes having nothing to do with floppy disk controllers. To expand the capabilities of the computer, I decided to assemble a ZX MultiSound sound card. But here, too, I encountered the problem of re-marked Z80 processors that do not work at the declared frequency. I also checked the capabilities of the VDAC2 video card, created specifically for the ZX Evolution. To assemble MultiSound, I used the documentation and firmware from the repository: https://github.com/UzixLS/zx-multisound More detailed information on assembling the KR1818VG93 emulator can be seen on the Fun Old Gamer channel. Bad Apple Color works on ZX Evolution without any modifications with standard Spectrum color and built-in Covox. Video was converted by Konstantin Kalantay.
