8086

I see these inexpensive XT and 8086 replica laptops that say they run DOS 6.22 and they claim to use the XT BIOS and they have a 9 pin serial port, but I don't know if it is a real port or a USB emulated 9 pin serial port. The other issue is will the Software run on an 8 bit XT or 8086 with 640...
