  The PINSETM instruction format has changed as follows

  D/# = %1_DD_MMMMM_BBBB_AAAA_LL_T_PPPPPPPPPPPPP
  is now
  D/# = %BBBB_AAAA_FFF_PPPPPPPPPPPPP_T_D_MMMMM_1
  

  That is probably the cause of your issues

  Here's a sample of my current async tx code

  	baudrate = 3_000_000
  	nco_baud = round(float($1_0000) / (float(sys_clk) / float(baudrate)))
  

  screen_grab	pinsetm	#%1_11110_1,#tx_pin
  		pinsetx	##$8000_0000 | nco_baud << 16 | %1_00000 | 7,#tx_pin
  		setb	dira+tx_pin>>5,#tx_pin
  		loc	ptrb,#@palette
  		mov	adrb,##(264+(384*1024))
  .loop2		rdbyte	adra,ptrb++
  .loop1		pingetz	ptra,#tx_pin wc
  	if_c	jmp	#.loop1
  		pinsety	adra,#tx_pin
  		djnz	adrb,#.loop2
  		ret

  IT would have been easier if I had been looking at the right documentation:)
  
  Supposedly, I will have time to try this out tonight.
  
  P2 is looking fabulous.
  
  I assume that the only issue with the NTSC stuff is setting the NCO correctly.

  Remember the DAC's are set using PINSETM as well.
