Yes. Sam Coupe is very cool ZX compatible computer. But compatible only with ZX48kB. Extended memory use 32kB ram paging instead 16kB paging on ZX128/Pentagons. After connect 1MB ram can SAM COUPE use also 16kB ram paging similar as ZX128/Pentagons. More info here:

All existing software for ZX48 can be recoloured with new colour palette, can run at similar speed as ZX or at 6MHz turbo. Interrupt position is reprogrammable, can be set on screen line 0-191 (191 = similar as on Pentagon, at end of screen).
SAA1099 sundchip are used also on russian ZXM SOUNDCARD and use compatible ports with SAM:

Graphic mode is 1 is compatible with ZX and full 512kB ram can be used as 32 videorams. Graphic mode 2 is hardware multicolor with linear screen data. Mode 3 is hi-res color mode and mode 4 is ZX mode without attributes (color pixels). Each pixel can use one from 16 colours with palette. Data are linear (24kB for one screen). Ram 512kB can contain up to 16 videorams in this mode.
FDD is based on VL1772 (controller used on ATARI ST or +D/DISCIPLE for ZX. SAM COUPE basic is based on MASTER BASIC for ZX Spectrum.
