can you add an example of sprite moving? please!

How does it work to use logic operators in the transfer? Is it possible to set it up with three sources and create a bob routine?

The Accelerator works like external accumulator with N-byte length (N value
is setting by "LD D,D" command).
When the Accelerator is switched on, the commands set of Z80 is changed.
And only commands which not uses a data are not changed.

LD L,L - switch the Accelerator to copying a data block mode
LD A,(HL) - load a data to the Accelerator memory
LD B,B - switch the Accelerator off

LD L,L
LD (HL),A - get a data from the Accelerator memory
LD B,B

LD L,L
AND (HL) - AND operation with the Accelerator memory data and data
from (HL) - put a result to the Accelerator memory
LD B,B

OR,XOR - like AND operation

Example of program with logic operations:

DI

LD D,D 	;switch the Accelerator to define block size mode

LD A,N 	;set a block size

; LD B,B 	;it was optimised because we need not switch the Accelerator off
when the next command is an Accelerator command

LD L,L 	;switch the Accelerator to copying a data block mode

LD A,(BC) 	;get a data to the Accelerator memory from (BC)

; LD B,B

; LD L,L 

AND (HL) 	;AND operation with (HL)

; LD B,B

EX DE,HL

; LD L,L 

OR (HL) 	;OR with (HL)

; LD B,B

EX DE,HL

; LD L,L

LD (BC),A 	;put a data to (BC) - a result is N-byte string: (((BC) and
(HL)) or (DE)) 

LD B,B 	;switch the Accelerator off
