; MXO-HP1.ASM -- Hewlett Packard overlay file for MEX114. 04/27/89
;
; This overlay adapts the MEX114 program to the HP125 Series 100.
;
; You will want to look this file over carefully. There are a number of
; options that you can use to configure the program to suit your taste.
; You use the AIDS and SOFT KEYS to configure baud rate and other para-
; meters.
;
; The HP125 uses two Z80's one for I/O and the other for crunching.
; Needless to say HP doesn't let the number crunching Z80 talk directly
; to the I/O ports, so direct communication with the ports is out. As
; luck would have it HP did include RDR: and PUN: routines, these rou-
; tines have been used in this implementation. NOTE: Special routines
; were required to device map the PUN: and RDR: to PORT 1 and to get all
; 8 bits of data in and out of the port.
;
; Edit this file for your preferences then follow the "TO USE:" example
; shown below.
;
; TO USE: First edit this file filling in answers for your own
; equipment. Then assemble with ASM.COM or equivalent
; assembler. Then use MLOAD to overlay the the results
; of this program to the original .COM file:
;
; A>MLOAD MEX-HP1=MEX114.COM,MXO-HP1.HEX ;Overlay MEX114.COM to produce
; MEX-HP1.COM
