Re: [Freedos-user] SNMP agent for DOS?

Hi Anton,

The machines are indeed physical with custom made ISA Bus controller 
cards, built on prototype board, and only 4 were made, 2 in production 


That sounds exciting!


plan is to eventually replace ... with something more ubiquitous.


Looking at other forums, people do impressive things combining old
and new hardware. For example there are tiny modern microcontroller
based extension cards for old PC, emulating all sorts of classic
boards, people convert from TV to HDMI using DSP based boards and
DOS expert RayeR is working on a way to connect classic ISA sound
cards to modern mainboards through the LPC bus on the TPM header!

For more general purpose things, Raspberry Pi style computers can
be a good option, natively running Linux, sometimes other operating
systems, or emulators for retro operating systems inside Linux,
while at the same time offering a variety of GPIO and bus systems
suitable for different control projects.

Have a good evening, too! Eric

I apologize for the slow reply, I have been caught up to the neck with 
work! Wow, what an interesting read this thread has been, you guys 
certainly have lots of experience.


Thanks Roderick for the link to DMH Software, I'll have a look at it, 
and thanks Frantisek, that was an interesting read. I fully agree on not 
touching stuff that works. I'll try to use the examples you described to 
convince the IT-adm dept that this idea is bad.


The machines are indeed physical with custom made ISA Bus controller 
cards, built on prototype board, and only 4 were made, 2 in production 
and to spares. I find this stressful, sure the two production cards have 
been in use since decades ago without failing, but it is not a viable 
long term solution to rely on these controllers.


But as you guys said, it's working on borrowed time; my long term plan 
is to eventually replace the legacy equipment with something more 
ubiquitous. Sometimes it feels like working in a museum. But as Michael 
wrote, $$$ is always an issue, as well as time and lastly everything is 
so insanely poorly documented!


I also got the IBM Systemview agent working, and it is indeed SNMP 
compatible, and the OS/2 is not controlling any equipment :)


Have a good evening!

Anton
