How mechanics keep 50-year-old BART trains running: Windows 98, eBay, and scraps
There is something wrong with the description of the laptop use (besides calling DOS a language) - on one hand they are running windows 10 with Win98 virtualized. Then they mention Thinkpads circa 2000. I&#x27;m pretty sure Win10 won&#x27;t run on those machines, so I guess the old laptops are for the interface to the train computers - RS-232 is my guess (could be the parallel port). If all they are using the DOS software for is to dump a log from the train, then it sound to me, that sniffing the protocol would be fairly simple. Calling people from bay-area hacker spaces to give them a hand in creating something more modern.
