For the record, the machine is running the mTCP web server: http://www.brutman.com/mTCP/mTCP_HTTPServ.html

I wrote it back in 2014 and I've hosted brutman.com on it at times. My usual machine to run it on for torture testing is a PCjr with a hard drive and Ethernet. This 386 would be so much happier with an Ethernet card; the serial port connection is really hurting the performance.

A new version of mTCP is in the works; look for it in the next two months.
