Software

I’ve been making quite a few things for the Commodore lately. Here’s some of my work.

CROSSWOZ

A cross-CPU emulator with a WOZMON-style monitor that runs in your browser. 6502, 65C02, Z80, 8080, 8085, 6809, 1802, and TMS9900 share one 64K memory bus, and you swap the chip with a single command. Open it or launch directly.

RPN-16C

A programmer’s calculator for iOS inspired by the HP-16C Computer Scientist. Hex, decimal, octal, and binary arithmetic, configurable word size from 1 to 64 bits, one’s and two’s complement, the full set of bit operations, and keystroke programming with labels and loops. It adds a two-line display and a wider binary readout than the original ever had. Read more.
