The Pocket8086 is a handheld retro computer built around classic 8086, 8088, NEC V20, or NEC V30 processors, giving it the performance and behavior of an 8086-class retro computer while still offering the convenience of a compact handheld form factor. Designed for vintage-computing enthusiasts, DOS gamers, and makers, it delivers a handheld retro computing experience suitable for DOS 6.22 as well as Windows 3.0/3.1, effectively packing an XT-class machine into a portable device.
The device integrates a 4.77–10 MHz CPU, 768 KB RAM, a replaceable TVGA9000i-based VGA card with 512 KB VRAM, OPL3 (YMF262) audio, a built-in mouse, PS/2 support, VGA output, CH375B-based USB mass-storage (U-disk) support, and a 512 MB CF card for IDE-mode storage. It features an IPS LCD with 4:3 and 16:9 modes (640×480 / 800×480), and includes OSD/SOSD menus for display tuning and system status. A 4,000 mAh lithium battery, open hardware documentation, and expansion options (8-bit ISA, parallel port) make it suitable for retro game development, DOS productivity, hardware tinkering, microcomputer education, and general PC-XT exploration in a portable form.

Pocket8086 ships with MS-DOS 6.22 preinstalled on its CF card and supports Windows 3.0/3.1 when it’s running with an NEC V20/V30 CPU, while still remaining fully compatible with classic DOS software and XT-era applications. It includes built-in support for the CH375B USB mass-storage driver, VGA output via a TVGA9000i card, and OPL3 audio for games and demos, along with a modified IBM PC-XT 05/08/86 BIOS that retains compatibility with legacy DOS utilities, boot loaders, and hardware-level extensions. The CF-based storage can be restored through Ghost image recovery, and the system supports standard DOS mouse drivers, PS/2 keyboard and mouse protocols, and typical DOS/Windows file-system workflows without altering their technical behavior. You’ll find resources like schematics, source code, and a user manual on the 8086cpu.com website.
The company also provides the ISA8-Exp-01, an 8-bit ISA expansion board that converts the Pocket8086/Pocket386 internal ISA header into a standard ISA slot, allowing users to plug in classic ISA cards such as sound cards, network adapters, storage controllers, and other legacy modules for expanded retro-PC functionality.
The Pocket8086 is designed by 8086YES! in China, who also designed the OneChipBook-12, a Cyclone EP1C12Q FPGA development platform with a built-in display and mechanical keyboard. Other x86 retro computers include the TinyLlama x86 retro computer board, which also runs DOS games on a DM&P Vortex86EX 32-bit x86 processor, and the Mainboard Terminal, a retro-style computer with a round display powered by the mainboard found in the Framework modular laptop, which runs Linux.
The Pocket8086, a handheld retro, is available on AliExpress for $166.73. The SA8-Exp-01 ISA bus expansion card is also sold separately on AliExpress $17.94. If you are looking for something a little more powerful, there’s also a 386SX version sold on AliExpress for $225and Amazon for $269.99.

How can it run windows 3.1 when it requires at least 286 and 1MB of ram, neither of wich this machine has?
it probably doesn’t. An error by the person who wrote the post. On the actual product page for this product only 3.0 is claimed to run.
it seems however that these devices are not currently available anywhere….
Good question even without extended mode 80286 is a must.
Without at least 486 dx4 100MHz it does not suite to true dos gaming.
TBH useless product.
Well Windows 3.0 seems to keep real mode as an option, but 3.1 removed it.
Maybe it mislabeled 3.1, but means 3.0?
The photo shows 3.0 and I had used it on a 8088 long ago, so I’m fairly certain it does work.
Well considering this device comes with >640K memory, it’s also possible that the UMB enables Windows 3.1 standard mode?
Apparently, the market for vintage/retro computing is more lucrative than expected because the products just keep coming.
It’s interesting to see that 45 years later, chips like 8284, 8237, 8254 and 8259 are still being made! I’m wondering what they’re being used for nowadays if they’re still sold. Also, there were so few transistors in all these chips that nowadays all of these could probably be re-implemented in a 7nm FPGA that would deliver the same performance at a few milliwatts.
Another point, the V20/V30 normally also have a Z80 mode that you can switch to using a far jump after setting a bit somewhere (I don’t remember where). So such devices might very well be usable with CPM/80 as well for those who still have software to run on it.
