    I have three 8 inch CP/M disks with MT+ Pascal.  There is source
for using the 9511 on one of them.  I've appended the files
"AMDIO.SRC" and "TRAN9511.SRC".  There are files named "FPRTNS.ERL"
and "REALIO.ERL" that are referred to in a file named "AMD9511.CMD"
but it's obvious that they aren't text files.

"AMDIO.SRC" follows:

MODULE AMDIOROUTINE;
(*----------------------------------------------------------*)
(* THIS MODULE CONTAINS TWO "ASSEMBLY" LANGUAGE SUBROUTINES *)
(* WHICH ARE CALLED FROM THE FPRTNS MODULE AND IF LOADED    *)
(* THE TRAN9511 MODULE.					    *)
(* 							    *)
(* THESE ROUTINES ARE SPECIFIC TO PASCAL/MT+ AND PASS       *)
(* PARAMETERS BACK AND FORTH THROUGH REGISTERS		    *)
(*							    *)
(* THE USER SHOULD CHANGE THE PORT NUMBERS AS NECESSARY     *)
(* FOR THEIR PARTICULAR HARDWARE IMPLEMENTATION OF THE 9511 *)
(*----------------------------------------------------------*)

PROCEDURE @O95D;	(* OUTPUT A-REG TO 9511 DATA PORT *)
BEGIN
  INLINE("OUT / $88)	(* CHANGE TO YOUR 9511 DATA PORT NUMBER *)
END;

PROCEDURE @O95C;	(* OUTPUT A-REG TO 9511 CONTROL PORT *)
BEGIN
  INLINE("OUT / $89)	(* CHANGE TO YOUR 9511 CTRL PORT NUMBER *)
END;

PROCEDURE @I95D;	(* INPUT A-REG FROM 9511 DATA PORT *)
BEGIN
  INLINE("IN / $88)	(* CHANGE TO YOUR 9511 DATA PORT (SAME AS @O95D)
*)
END;

PROCEDURE @I95C;	(* INPUT A-REG FROM 9511 CONTROL PORT *)
BEGIN
  INLINE("IN / $89)	(* CHANGE TO YOUR 9511 CTRL PORT (SAME AS @O95C)
*)
END;

THE AM9511 LITERATURE).  THE SECOND IS THE ADDRESS OF ARG, A
REAL VARIABLE, THE FUNTION ARGUMENT IS IN ARG, AND THE RESULT 
IS RETURNED IN ARG.  THE THIRD ARGUMENT IS THE ADDRESS WHERE 
THE APU STATUS IS RETURNED.}
