24 alternatives to The BLAKE3 hash function running on a 6502 microprocessor
the BLAKE3 hash function implemented in 6502 assembly - oconnor663/blake3-6502
BLAKE3 is a cryptographic hash function implemented to run on the 6502 microprocessor, a CPU from the 1970s commonly found in vintage computers like the Commodore 64 and Apple II. The project is for retrocomputing… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. The BLAKE3 hash function running on a 6502 microprocessor launched in 2022; newer entries below may have overtaken it.

Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

The core question: how did HP's scientific calculators actually work at the gate level? That rabbit hole led to building one from scratch. The architectural decision everything else follows from: a decimal calculator should store numbers as BCD — one decimal digit per 4-bit nibble. A standard byte-oriented CPU (Z80, 6502) fights that layout constantly. So I designed a small custom CPU in Verilog where 4 bits is the natural data width and memory is nibble addressable. What the project covers: - Custom CPU: Harvard architecture, 12-bit ISA, 8-state execution FSM, hardware stack guard with a…
