Comfortable loading of ZX games to SAM COUPE
« dnia: 2012.03.20, 22:55:25 »
Exist more ways for load ZX games to SAM COUPE. As first we must switch SAM to ZX Spectrum mode. And yet ?

- 1) use ZX emulator with possibility open TAP files from FDD / Atom HDD (virtual fdd drives only) / CD-ROM
- 2) use ZX emulator with support loading software from real tape ( too slow )
- 3) use easy ZX emulator (only original ZX rom), use SAM to ZX BUS adapter, connect DIVIDE interface.

Yes, DIVIDE work on SAM COUPE, but only if original ZX48 rom is used in low 16kB. DivIDE interface use same port as SAM FDD then you must disconnect FDD drive. DivIDE must be with open both jumpers after power-on SAM COUPE. After start ZX emulator on SAM COUPE write and run this code:

DI
LD BC,#8000
LOOP1  DEC BC
LD A,B
OR B
JR NZ,LOOP1
CALL #1FFB
LOOP2  LD A,R
AND 7
OUT (#FE),A
XOR A
IN A,(#FE)
CPL
AND #1F
JR Z,LOOP2
RST 0

After start program show multicolor lines in border area. You connect left jumper on DIVIDE interface (jumper E) and press any key for reset ZX rom with DIVIDE support.

Only SAM's reset button is unusable if on divide is connect jumper... (SAM after reset connect sam coupe rom, disable ZX mode and DivIDE work incorrect).

Does the SAM have the same ZX-bus like ZX Spectrum?
