Why are small labs and workshops still running the business on a DOS machine with no backup plan?

Testing labs, workshops and small factories still depend on DOS software and ISA-card instruments that nobody can replace, so a dead disk or motherboard means weeks of downtime and the knowledge of how it works lives in one person.

Who has it: Owners and technicians of small labs, workshops and factories running dBase-era software and instruments on decades-old PCs, and the IT consultants who inherit them.

“He didn’t have much of a backup plan for the imaging hardware though.”

Existing players

Emulators such as 86Box and DOSBox · Run the old software, but need an expert to set up and do not cover ISA instrument cards or dongles.
Spare period PCs in a storage room · What owners do today, which only delays the failure.
Custom rewrites by consultants · Costly, and the original business rules are rarely documented.

What they are missing

A rescue service that images the old machine, runs it in an emulator with the instrument interface bridged, uses an LLM to read the old programs and databases and document what they do, and produces a migration plan to a modern tool.
