Astrobe Forum

In this Oberon-1 paper (http://norayr.am/papers/WirthTasksVersusThreads.pdf) from 1996, Wirth discusses a method of "real-time tasks". (Page 10). In which I believe interrupt handlers installed with Kernel.Instal(Handler, N) are triggered when a device or buffer is updated?

I see that Kernel.Install still exists in the RISC5 source. Can this method still be used for "real-time tasks" in which a procedure is run when an external stimulus changes? So far all the interrupt examples I've seen make use of interrupts triggered periodically by the millisecond timer, but I'm a little out of my depth here so it's very possible I missed something

My end goal is to trigger an interrupt (from firmware or otherwise) without having to wait for the millisecond timer

Oberon's interrupt capabilities are part of Project Oberon and the RISC5 design - they are not peculiar to Astrobe. Unfortunately we have not had any experience in what you are attempting to do. However, I recommend that you check out this website produced by gray, another Astrobe user and frequent contributor to this forum:

Alternatively, try asking your question on the ETH Oberon Mailing list.
