MPU302	Motorola 68302	Custom 96-pin DIN41612	Please note the expansion bus header is not compatible with ECB bus. Repurposed SPX MPU board for CP/M 68K. Read about it on Hackaday
PE6502	WDC 65C02	Custom 40-pin	65C02-based, low parts count/easy to assemble, Wozmon/Integer BASIC/AppleSoft Lite/Krusader Asm/Disasm/Debugger built-in ROM, 32K SRAM, Propeller term.
MC14500	MC14500	NA	MC14500 board. Uses switches to load data/commands.
SDC	8080 8085 Z80 65C02 65C816 MC68008		Simple boards with various old microprocessors with the whole logic of a computer other than the CPU implemented in an STM32-family microcontroller. The boards are powered via USB from a PC and communicate with a terminal program on the PC via two virtual COM channels implemented in an USB device. The first VCOM provides a command interface to a hardware monitor for controlling the CPU, single-stepping with disassembly, .HEX file loading, etc., while the other serves as target computer's console.
