AgonLight. A stand-alone, BASIC-programmable microcontroller and microcomputer in one! The fastest, cheapest, most hackable 8-bit computer ever.

CERBERUS2080. CERBERUS 2080™, the amazing multi-processor 8-bit microcomputer, featuring Z80, 65C02 and AVR processors.

CERBERUS2100. The amazing multi-processor 8-bit microcomputer, featuring Z80, 6502 and AVR processors. Built with CPLDs, CERBERUS 2100™ is fully programmable even with respect to its hardware, at the individual gate and flip-flop level.

AgonORIGINS. A stand-alone, BASIC-programmable microcontroller and microcomputer in one! The fastest, cheapest, most hackable 8-bit computer ever.

6502-to-W65C02S-adapter. A small daughterboard adapter that replaces a 6502 processor (used in vintage 8-bit computers such as the VIC-20, Apple II and BBC Micro) with a modern equivalent. Two versions are provided, which fit different motherboards.

Sally-to-W65C02S-adapter. This is a small adapter, in the form of a daughter board, which fits into the socket of the "Sally" CPU of the Atari 800XL microcomputer. It replaces that CPU with a CMOS, modern, low-power, fully static, currently in production W65C02S and some auxiliary logic. The project has been featured in three videos in my YouTube channel ("The Byte Attic," https://www.youtube.com/channel/UCfzZNuoHys1t-AdwYDhOz8g).

TalosES. Talos ES™ is a mini-computer, built with standard, discrete logic (74-series chips), featuring a custom RISC CPU. It's meant for education and entertainment.
