A 1950's Hammond organ with all it's intricacies can still be used today...I have been liquidating gear that "isn't supported anymore" and very much minimizing gear that relies on software as much as I can...as keyboardist I'm stuck knowing that in about 3 years I'll have to dump the keys I have now a Nord Electro 4 and Yamaha MOX for newer gear so it will be supported ...just the way shit goes now...
My Hammond L from around '65 is still running strong.
So is my 2" Otari tape deck from the late '80s...like my Trident from that same period, and having recently overhauled it, I should see another 20 years out of it at least.
I've got a few other vintage pieces that are working fine, or need just a bit of overhaul to get them back to spec.
Try that with some old piece of software that is no longer supported and can't run on any current OS because there aren't any drivers. You can't do anything with it except by a new version of it or toss it....or if you still have some old computer hardware, you might be able to use it, but then you're stuck, 'cuz all the new software you have won't run on the old hardware.
That's the one thing I really hate about the computer upgrade tango...you run out and upgrade the hardware, and suddenly you need to also upgrade a whole lot of software too...or vice versa...and you're lucky if you can even do either of those things successfully where you don't end up losing anything in the process that won't/can't be upgraded...and that's just basic computer use. For us audio guys, it's even more of a PITA when you throw in the interfaces and anything else that goes with them. It can be a disastrous domino effect just from changing one key piece in your digital rig.
Not to mention, even the stuff you CAN upgrade "successfully"...it can be worse than getting a root canal and colonoscopy, simultaneously, and without any anesthesia.
It seems that just when you have all your hardware/software configured and running smoothly...something new comes out that triggers the upgrade tango all over again if you want to stay 100% current.
