SIO2PC has actually been around a while, but I call it modern because it was not a thing in the 80s. SIO2PC is a device that allows a PC (or Mac) to be connected via the SIO port to an Atari 8-bit and with companion software, the PC can emulate a floppy drive.
Although I have actually floppy drives (an Atari 1050 and a Rana 1000) and I technically have plenty of ways to emulate Atari floppy drives, including S-Drive Max, FujiNet, Side3, I wanted to test out an SIO2PC as well.
I recall first hearing about SIO2PC back in the 90s, but I never actually tried it until recently. In fact, I originally thought its purpose was to allow a disk drive, such as a 1050, to be hooked up to a PC. It turns out it does the opposite.
