Hello,
is use this function :

10 screen 8:vdp(9)=2 : rem vdp(10)=vdp(10) and &H7f
20 set page 0,0:cls
30 bload "grp.sc8",s
40 call turbo on
50 for l=0 to 16383 : vpoke 212°256+l,vpeek(l):next L
60 line (0,0)-(256,211),200,bf
70 copy (0,212)-(32,212+32),0 to (100,100),0
80 call turbo on
90 vdp ( 7 ) = 255
100 goto 100

But can't see the graphic 32x32 in screen 8 (as screen 5-6-7!!) and this myster is not resolve 100% with CALL TURBO ON
Away, set CALL TURBO OFF, but away the problem of 32x32 HINT on screen!

Is use the source of command #D0 ? is ok o no ? Can't now the test, is wrong ? The graphics of screen 8 is two pages,
yes, but two block is hint 212 to 256, the size is 16384 bytes (16k !) extra for make copy 16x16 or 8x8 with
CALL TURBO ON/OFF and use NestorBASIC with block RAM to switch and send to VRAM.

Because the new problem of 0,212 to 256,256 the COPY BASIC is not resolved, but the command #D0 is OK?
Bye bye

on msx2 vdp(9)=2 is false because bit 3 used for the size of the memory and 0 is 16k memory
use vdp(9)=vdp(9)+2
after i have owerflow in line 50 the L=11264 try with 11263 for l
for viewing the screen work added 35 vdp(24)=100
i think the copy don't work with coordonate 212 and after because the basic cut after 211
testing on turbo-r but missing line 40 and 80

Ok, but you make the example source for BASIC, why can't find other solution.
? ? ?

See this !!
Mode SCREEN 8 :
block 0: #0000 - #4000
block 1: #4000 - #7FFF
block 2: #8000 - #BFFF
block 4: #C000 - #FFFF page 0

And alternative, you are make the binary with #D0 command VDP ?!?! If you have resolved, please make the example
on BASIC.
OK!!

You make the example on BASIC to test copy from 0,192 to 256,256 to (0,0),0 !!
And this is necessary to modify / Adding soluction to my program BASIC for screen 8 !
