Custom PCB ISA card uses a Raspberry Pi Zero W to provide a server to a PC/XT

Scott Baker has a vintage computing habit! For his latest project, he wanted to solve the issue of transferring files between a PC/XT and a modern desktop. To do this, he created an ISA card PCB (seen above) which takes a Raspberry Pi Zero W, mounted by the GPIO pins. A 1kb RAM chip allows communication between the ISA interface and the Pi and the Pi runs a Python server that makes local files available to the shared memory on the ISA card. The PC/XT believes that it has a floppy connected, but what it actually has is the Pi server! You can read a lot more over on Scott’s blog and see a video of it in action, along with lots of details, below:
