ZXMGR and ZXLDR on real ZX SPECTRUM +3

Video captured via TV-capture card from real ZX-Spectrum. To be true, it’s ZX Spectrum 2A with SI-1 controller(but result is totally same as 3) and HxC Floppy Emulator(to emulate 3“ discs). SI-1 controller contains same schematics that present in usual 3 and with connected SI-1 your 2A or 2B will be same 3 speccy.
