   My Pocket 386 arrived! It seems to have basically the same specs as the Hand386, but in a laptop form factor. There's a few new options for managing the video, and the built-in screen isn't as horribly shit this time.

     Pocket 386. I'll need to put some stickers on this thing. Maybe a "Don't copy that floppy!" or something equally DOS. I think I still have some Duke Nukem 1 stickers...

     Your right side has the line out and the power button. It's pop-in/pop-out, not momentary.

     Left side has the removable hard drive (CD card), USB slot (which is just used for mass storage, it's not generic USB host), and an unlabeled port. I believe this one is designed for parallel port use, it came with an adapter.

     Back of the laptop, we've got a power jack (12V 1.5A), and 4 slots.
     One is PS/2 keyboard/mouse and VGA, I think one is GPIO, the far right one is ISA, and I'm not sure what the other is (I don't have my manual handy)

     I was right, except the right two back ports are both ISA: You can combine the two for 16-bit ISA now, not just 8bit!

     There's also a Mini-ISA/GPI socket, which I think is documented somewhere

     OKAY, so, internals. (Sorry I'm gonna have to go fast and skip image descriptions, I'm about to leave for work)

     First off, the keyboard: It's mini scissor switches, pretty standard for a tiny laptop like this. We do have two speakers, so there's presumably stereo sound. I'll have to run a stereo test later.

     That video card is very barebones. We've got a VRAM chip, flash chip, and the GPU. Everything else is some resistors, caps, and a transistor.
     It uses that same mini-ISA connector.
     I don't think that's a pre-existing standard, I think they just invented it right here.

     With it we get two chips:
     A Sharp LH6A4260K-60, the same one used on the Hand386. I think this is a half-meg chip.

     The SST MPF39SF512 is a 64 kilobyte chip, for the video ROM

     Same CPU as the Hand386:
     A DM&P M6117D. This is a Nvidia chip licensed to DM&P, originally by ALi. It's a 386SX-compatible SOC, based on an Intel design, running at 25-40 mhz (this one is clocked at 40) and can handle up to 16mb of ram

     USB is powered by a WCH CH375B. This is the same chip as on those ISA-to-USB cards. It's basically an 8051 acting as a USB host. The driver does the heavy lifting, but it is USB storage only.

     I forgot to check which version of the driver it's using. There's a bunch, with varying capabilities.

     An XLSEMI XL4015E1: A DC to DC converter. It takes 8-36V and converts it to an output of 1.25v to 32v, depending on how it's configured. I'm betting this drops the voltage from the 12v AC adapter to a charging voltage for the battery.

     U31 here is an Xysemi XR2981 24-watt step-up DC-DC converter. This takes something between 3.3 and 5v and turns it into a configured voltage. I'm guessing this is taking the 3.7v from the battery and turning it into the 5v this thing runs on

     U32 is an INJOINIC IP2312 battery management IC.
     So this is probably used to measure the battery voltage to estimate capacity, as well as send a LOW VOLTAGE POWER OFF IMMEDIATELY signal to the main CPU

     so there's a lot of fun projects you could make with that design.
     With a few level shifters and 74-series logic you could make an adapter to an ESP32 and give this thing wifi.

     it comes with the same stuff as the Hand386, maybe a few more games. You've got Planet X3, Doom, Wolf3d, a few other shareware titles and some benchmarking utilities.

     @foone Thanks, sounds like mine is faulty then. Wouldn’t come on at all out of the box, and the charge light comes on when plugged in, but after sitting “charging” for a few hours, it still won’t run on battery power. Works great plugged in though.
