MicroBeast is a build-your-own Z80 computer that folds a keyboard and display into a compact, standalone machine. It runs CP/M 2.2, includes 512K RAM and 512K flash ROM, and offers USB-C, GPIO, I2C, and RC2014-compatible expansion. It is a hands-on kit, not a ready-to-use appliance: the surface-mount parts arrive assembled, but you still solder through-hole components and use basic hand tools.
What is MicroBeast?
MicroBeast is a hobbyist 8-bit computer built around a Z80 processor. Unlike a single-board computer that expects an external keyboard and monitor, it integrates its own keyboard and character display in a folding enclosure. The manufacturer describes it as a complete standalone computer intended for building, learning, and experimentation. Those are design aims, not independently measured educational outcomes.
The project’s earlier Hackster coverage described it as a foldable computer and discussed learning low-level concepts such as registers and Boolean operations. That article reflects an earlier point in the product’s development; the manufacturer’s current product page is the better reference for specifications.
MicroBeast specifications and connections
| Feature | Manufacturer’s current specification |
|---|---|
| Processor | Z80 CPU, 8–10 MHz |
| Memory | 512K RAM and 512K flash ROM |
| Operating system and firmware | CP/M 2.2 and a custom BIOS; flash ROM is supplied with a basic monitor and CP/M 2.2 |
| Display | 24-character, 14-segment display |
| Keyboard | 47 keys |
| Power and data | USB-C; auxiliary power input |
| Expansion and interfaces | 12 GPIO I/O pins, I2C header, and RC2014-compatible expansion port |
| Other hardware | Battery-backed real-time clock, speaker, and FTDI header |
The manufacturer lists 47 keys. The older Hackster article says 48, so use the current manufacturer specification when the exact count matters. The manufacturer also cautions that MicroBeast is a hobby project in continuous development, which means specifications and product information can change.

What comes in the kit?
The shop listing describes a kit that includes the MicroBeast box; a PCB with surface-mount components already fitted; through-hole components and ICs; keyboard switches and keycaps; a keyboard frame and mounting blocks; keycap stickers; a display filter; and a fold-out instruction booklet with schematics. The flash ROM is preloaded with a basic monitor and CP/M 2.2.
Pre-assembling the surface-mount parts reduces the work, but this is still a soldering project. The maker says builders need a soldering iron, solder, flux, side-snips, a 2 mm Allen key, and needle-nose pliers. An anti-static wristband and mat are recommended, and a multimeter can be used for basic checks. The soldering iron and other tools are not listed as kit contents.

What can you do with it?
Use CP/M on a self-contained machine
MicroBeast is designed to boot into CP/M 2.2, the classic operating system for Z80-era computers. Its onboard keyboard and display let it operate as a standalone system rather than requiring a separate computer for basic interaction.
Explore the hardware
The GPIO pins, I2C header, and RC2014-compatible expansion port provide ways to connect hardware and extend the system. USB-C supports power and data, while the FTDI header and custom BIOS give builders additional avenues for working with the machine. The manufacturer presents experimentation and expansion as goals; the connectors alone do not establish compatibility with every peripheral or guarantee a particular project will work.

- Application: Compatible for Genie ALC1000 Z80-60RT Z135-70RT ZX135-70RT
- NOTE: To avoid unnecessary returns please check the part number before purchasing or tell us the picture of your engine model and nameplate to reduce the error rate.
- TIP: If you cannot find the required product part number, please consult us and we will reply as soon as possible.
Learn by building and experimenting
Assembly and access to the underlying hardware can make MicroBeast a tangible way to explore how a small 8-bit computer is put together. It is best suited to someone willing to solder and work through a kit’s instructions, rather than someone looking only for a finished retro computer. The available product information does not quantify learning outcomes.
Ordering, price, and availability
The manufacturer’s shop lists the kit at £150, with approximate equivalents of $198 or €172 before tax and postage. The shop says it accepts pre-orders because kits are assembled in small batches, and that it will contact customers to confirm payment and delivery options when a kit can be fulfilled. It also states that a 10% import-duty charge is added for kits sent to the United States. These are shop-page terms and prices, which can change; check the current listing for stock, total cost, taxes, shipping, and timing before ordering.

Is MicroBeast a good fit?
- Consider it if you want a Z80-based kit with an integrated keyboard and display, CP/M, and accessible expansion connections—and are comfortable soldering through-hole parts.
- Look elsewhere if you need a ready-assembled computer, want a modern graphical display, or do not have access to the required tools and assembly skills.
- Plan for uncertainty if timing is important: the maker describes small-batch pre-orders rather than a guaranteed immediate shipment.
MicroBeast occupies a specific niche: a foldable, self-contained computer for people who want to build and explore a real 8-bit Z80 system. Its mix of onboard input and display, CP/M, and expansion interfaces makes the concept distinctive, while soldering and small-batch ordering make it a project to approach with realistic expectations.
