:P

I totally agree that the APC network cards are... for lack of a better term, a steaming pile. Unfortunately, when you have quite a few older UPSs and PDUs with old cards like the AP9606 that are still in service...

I work pretty heavily these days in repair, refurbishment, and upgrading of legacy equipment from various fields - changes of career can be fun and rewarding, and in this case, a bit more relaxing from not being on call 24/7.

When the vendor is long gone, replacement parts are scarce, and everything is serial based, you learn pretty quick that quirks and timing issues can wreck and trash a controller. Usually equals the junking of whole pieces of machinery or expensive replacement parts.

So, while some people have messaged me off list giving me grief for suggesting it, I have my reasons for desiring such a 'strange beast'.

In the meantime, I've got a passive ISA backplane, a collection of 286, 386, and higher proc boards, and misc ISA serial boards (why oh why did some vendors use RS-485 on some controllers???).

On an unrelated side note and not directed at you... I read messages on this list at times, and I have to wonder if some people here forget where they came from when they first started out in the field or building their own company.

Sometimes, its not possible to just replace or upgrade things in active service just because they are older, or because they are quirky. Yeah, its easy to say, "switch vendors!", but in reality, we all know that is far from the truth.

I guess its easy lose sight of the fact that there's alot of companies and groups that don't have the luxury of million dollar budgets... or even tens of thousands in budget... Or run what they do as a hobby or charity.
