; M7-1HP.ASM -- Hewlett Packard overlay file for MDM7xx. 11/11/83 ; ; This overlay adapts the MDM7xx 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. ; ;*********************************************************************** ; ; W A R N I N G ; - - - - - - - ; ; ALWAYS DEPART THIS PROGRAM FROM THE COMMAND LEVEL, USING THE 'BYE' ; COMMAND SO THAT YOUR HP125 GETS RECONFIGURED TO IT'S NORMAL STATE. ; ;*********************************************************************** ; ; 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.
