Description
Glasur is an FPGA-based “front panel” computer designed primarily for educational purposes. It can be used to learn and teach about CPUs and FPGAs. It is also an experiment in building a minimal low-power self-contained computer that might still be useful if no other technology were available.
Currently available for reservation. Final appearance, specifications, pricing and features subject to change.
Glasur ships with a simple open-source 8-bit stack-based CPU and SOC that allows the user to manually enter machine code through its panel interface.
