Alice Averlong🏳️⚧️So my roommate bought that weird Hand386 portable PC that popped up on aliexpress. Let's tear it down (nondestructively for once, since I'm borrowing it).
first off, lemme get the spoilers out of the way: It's real, it runs DOS/Windows 95, and it can run Doom (badly) and VGAPride.
It's easy to open (this image came out blurry, but I'm just using it for navgiation)
We've got two terminal connectors on the left, plus a 3.5mm audio jack. The right has a USB port and a barrel jack power connector.
I love this, so I@foone but but the 386 didn’t have USB?!

@jpm @foone The gimmick is the CH375 chip-- it does all the "USB" heavy lifting and just exposes a pretty simple sector-oriented interface. From there, it's all drivers on the host-PC side to shim up something that handles normal BIOS INT 13 commands. With a little effort, you can even make a bootable device out of one.
