HP-75 - SRQ/interrupt and HPILCMDS.LEX?

[Paul Berger (Canada)]

The IO ROM for the 75 adds an 'ON SRQ' command that allows the 75 to respond to incoming SRQs. The IO ROM also contains all of the commands in the HPILCMDS LEX, but the "LEX number" is different so if a BASIC program was written using the LEX it will not find the corresponding commands in the ROM. The easiest way around this is to convert the file to text with the LEX file loaded and convert back to BASIC with the LEX file removed and I/O ROM installed.
