Ever needed a pocket-sized laptop that may play DOS video games and do just about every little thing else a 486 or Pentium PC may do? Then look no additional. TInyLlama, AKA Eivind Bøhler from Norway, has put collectively a board — that includes an 86Duino SoM and a Raspberry Pi Zero 2 for MIDI — that may just do that, and totally documented it on GiHub. Beware, although, you’ll must construct it your self.
On the core of the intelligent customized board is a Vortex86EX CPU – a 32bit X86-compatible IA-32 CPU made in Taiwan by DM&P Electronics – working at between 50 and 500MHz, a velocity no 486 or unique Pentium may even dream of. There’s 128MB of DDR3 RAM, once more a lot better than the 16MB that was frequent on the time, and 8MB of programmable flash ROM. A Vortex86VGA module runs off a PCIe 1x lane, providing a most decision of 1024×786, at a period-appropriate facet ratio of 4:3. Storage comes by way of Micro SD, and energy from a micro USB cable.
Sound comes by way of a Crystal CS4237B all-in-one audio chip, which is Sound Blaster Professional appropriate, however you’ll be able to complement this with a Raspberry Pi Zero 2 connected by way of a 40-pin connector that provides Roland MT-32 emulation and normal MIDI. There is a change for toggling between its two modes, and you’ll join an OLED show utilizing a four-pin I2C plug.
Software program help comes within the type of a customized Coreboot/SeaBIOS ROM, and it runs FreeDOS or the OG MS-DOS itself. There isn’t any point out of Home windows 95, although the Vortex86EX chip ought to be capable to deal with Home windows CE 6, Home windows Embedded Compact, and Linux as much as kernel 4.14.
There’s quite a lot of soldering to be achieved should you fancy constructing your personal TInyLlama, particularly because the SOM-128-EX system-on-module that kinds the core of the gadget has fully the improper pin structure and must be personalized. You then want to exchange the pre-installed bootloader and program the sound chip firmware. When you’re up for the duty, the design is open-source, and there is a full walkthrough plus BOM on the TInyLlama GitHub web page.
