The hardware was great for the time so I can only guess that small office didn’t need it any more. This was a small regional satellite office of a much larger company.
My boss at the time told me they paid $10k for that computer when it was new & the equipment it controlled would cost $1-2m to replace (I want to say it was a microspectrophotometer but my memory is blurry), so they had to keep that 386 around & in working order. Luckily these were apparently very reliable computers.
