They're not made to suit some big commercial goal, or produce the perfect device but to fit the current desires and capabilities of the people involved. MicroBeast is no different. So rather than claim this is the best ever computer, this is a list of the goals that drove the design. If these matter to you, MicroBeast could be your next computer! * A complete, self-contained 8-bit computer kit that can be built without specialist tools. * Genuine 8-bit design, don't cheat with "support" processors that are more powerful than the main CPU. * All development, from applications to firmware, can be done without expensive or obscure tools. * Use standard connectors. No odd or outdated adapters adding to clutter. * Use only currently manufactured and available components. 8 bit shouldn't mean obsolete. * Can be expanded, customised and hacked - with full access to the CPU bus. * Intentional, honest design - make choices, not excuses. * Keep costs down, but don't cut corners. The machine that inspired MicroBeast, the MicroProfessor II was part of the big movement in the early 80's away from one-off designs that enthusiasts might struggle to replicate, towards 'off the shelf' machines that were designed to be convenient and consistent for hobbyists. Therefore the primary goal in designing MicroBeast is to create a kit that is self-contained and easy to build and use. That means all components included, from nuts and bolts to base firmware. It means avoiding adding to the clutter of unique cables, adapters and power supplies that seem to come with many hobby kits. Even the choice of an inbuilt keyboard saves relying on a PS/2 keyboard connector that manages both to be obsolete and from a completely different period from 8-bit computing. It also means that all of the parts that need to be assembled are standard through hole components. The only tools required are a soldering iron and an allen key. In the quest to design a machine that's clean and simple, I've made a concious choice to use modern connectors and components where they make sense. The power supply and communications on MicroBeast are pre-installed surface mount parts. It features a USB-C connector and an efficient switching regulator so powering up couldn't be simpler. It also has a built in serial to USB adapter, so you can open a terminal on your PC and connect directly to the CPU. And for maximum flexibility, it's still possible to power MicroBeast through a separate barrel jack or use an FTDI adapter if you wish. Above all, the goal is to solve the problems of building a great looking, unique kit during the design phase without limiting how it might be used, hacked and extended later on. You can be the judge of whether or not I've succeeded. Laser cut keyboard frame Laser cut keyboard frame Laser cut keyboard frame News Great Reviews The reviews are in - and I couldn't be more proud. Denis: It's one of the best looking kit I've ever had. ... Overall, it's a very good kit with very good support from the creator... one of the best Z80 SBC I've seen until now. Phil: I wanted to say I am very impressed by the quality of kit, overall packaging, instructions, PCB quality, congrats for a great work Paula: Looks amazing and the case is gorgeous We're In The News! Things are taking off at MicroBeast HQ - thanks to lovely coverage at Hackster.io and on The Retro Hour Podcast I've seen many more visitors to the site, GitHub and the Discord channel. Kits have been going out to all corners of the world, and new batches are regularly available, so place your order and we'll get you going as soon as possible! In the mean time, work on VideoBeast is frantic, with new modes, features and demos coming out. This could make MicroBeast the fastest true 8-bit platform out there! CP/M 2.2 Welcome to Zork! After a lot of work, MicroBeast has it's own CP/M distribution. Running CP/M 2.2, with a ROM disk containing basic utilities, it's now possible to run classic games such as Zork. MicroBeast kits come with the Monitor and CP/M BIOS already loaded into the Flash ROM so you can be up and running as soon as possible. BeastEm - The MicroBeast Emulator Debug Screen To help develop software for MicroBeast, there is now an emulator that runs on Windows, Linux and OSX. Providing emulation of all MicroBeast hardware, a comprehensive debug screen and step-by-step code execution, BeastEm is a fully featured Z80 SBC development tool.
