   For VRAM, a Sharp LH6A4260K-60, which I'm pretty sure is a 512 kilobyte chip, but I can't be sure.

     Then we've got our VGA chip: A Chips&Technologies 65535.
     This is a fully integrated chip with built in CRT controller/flat panel support, RAMDAC, and and clocks.
     It supports up to 1280x1024 resolution with enough VRAM, or 640x480 16bpp truecolor.

     Next to the CPU, we've got four DRAM chips. AMIC A420616AS-50F, 2-megabyte chips.
     So we're looking at 8 megabytes.

     Chip info here:
     Also, I was wrong. Apparently it goes up to 64 megabytes of RAM:

     So the M6117D is a 386SX-compatible system on a chip.
     It's a static 386SX Core (apparently licensed from Intel?) plus ram controller, peripheral controllers, IDE support. It runs at 25-40mhz, and up to 16 megabytes of RAM

     First off, the CPU. This is surprising! It's an DM&P ALi M6117D.
     This is a modified version of the chip made by ALi/ULi, licensed to DM&P. ALi's chip division was bought by Nvidia in 2006.

     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.

     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.

     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).
