Although I have much more recent PCs running automation, I still use 1986 Compaq 286, upgraded HD and it still runs longer term Commodities system. On PCs I keep them two years but laptops eleven months, batteries usually shot by then.
Why would you run some legacy system from the 80s? This is nuts. Nobody in their right-mind would run a system on a 286 running DOS. It would be ported if it's not garbage. There is no company providing data on DOS.
I was running some long since unsupported stuff on a Solaris on an ancient Sparc20 (circa 1999) but gave up on that a couple of years ago. lol 286.
