This port is unusable on real ZX Spectrums (collision wih port FE and 7FFD,etc...) but complette schematic and port decoder can be modified (integrated to one CPLD)

For bus NemoBus collision will not.

Ports must be changed for better compatibility (possibility connect) with other ZX models/clones. A14 and A13 is not used in schematic.

What is the address used in the software?

??? For SIDINTERFACE exist only one player utility. All other ports than xxD4 is extra ports for SAM COUPE computer (memory paging etc...). This must be rewrited, if you need run this player on ZX/clones. Player is designed for Z80 CPU at 6 MHz, then on ZX clones must be used turbo mode. Player emulate in realtime CPU from Commodore 64 and is usable only for play original SID tunes. On ZX with this sidinterface is better direct access to SID via OUTs. Or write SID tracker for create new tunes.

What for so it is difficult?
Unless it was not easier to convert all SID tracks in dump registers and to play them primitive player on ZX?

By the way who this hero written emulator processor of C64 under z80?

Yes, is possible convert SID music to register values and play it on ZX. But file size will long.

This is emulation of CPU 6510.

For ZX Spectrum at 3.5MHz exist also more software emulators of machines based at CPU 6502. For example APPLE 1 emulators (ZX version in attachment)

APPLE 1 emul for SAM COUPE (Z80 CPU)

VIC 20 emulator , etc...

In clones using NemoBus, this electronic circuit will work without any alterations.

But on other machines it will problem. New interface must use compatible ports. (or can be designed only for computers with NEMO bus )

[Black_Cat]

or can be designed only for computers with NEMO bus

Modification of the original computers to the standard NemoBus solve all problems.
