OK, this http://www.worldofspectrum.org/zxplus3e/interface.html is Pera Putnik interface with just a couple of changes to the addressing. I write e-mail to Garry Lancaster and received this reply:
Yes, ZXCF (& ResiDOS) works with all 48K & 128K Spectrums. It should work with clones, as long as the BASIC ROM is not too different.
This is probably simplest interface IDE for ZX and maybe for "Byte".
