6502 · 2 MHz · VGA
ABN6502 r2
A 2 MHz 6502 computer with 32 KiB firmware, character ROM, green VGA display and keyboard. Try the F1 monitor and F4 BASIC.
80C31 · 11.0592 MHz · serial DOS
DOS/51
An 80C31 computer with 32 KiB ROM, two RAM chips and 19200-baud serial DOS. Try the shell, nano-like editor, assembler and virtual SD card.
What is emulated?
Real ROM images run on emulated 6502, 6507 and 8051-family CPUs. 65uino and ABN6502 show OLED and VGA; DOS/51 provides a serial console, RAM disk, assembler and SD card. These are useful ways to explore the machines, not replacements for physical hardware.
