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

I have two questions:
1) Is it possible to use HP-IL SRQ interrupts with the HP-75?
The series 80 machines have the ON INTR ...do something... statement, while the HP-75 seem to have no such capability. The only way to implement something similar seems to be a polling loop.

2) The only place where I found the HPILCMDS.LEX file is at Vassilis Prevelakis series80 web site. It hosts the 1252 bytes version which works fine. I read somewhere that there was a slightly improved version which is 1253 bytes long. Does someone have this version?
In the old days the original HPILCMDS.LEX file was obviously withdrawn from the swap disks due to copyright issues. Thus is it not part of the collections that I checked out.

Martin
