ESP32 chips have been used for retro gaming and computing for years, but Austin McChord (Amcchord) adds to that with a Macintosh emulator ported to a couple of ESP32-P4 display devkits.His project is a full port of the BasiliskII Macintosh 68k emulator, bringing classic Mac OS (System 7.x through Mac OS 8.1) to portable ESP32-P4 embedded devices with touchscreen, USB peripherals, and WiFi support through an ESP32-C6 on the boards.The main development platform appears to be the M5Stack Tab5 equipped with a 5-inch touchscreen display with 1280×720 resolution. However, if you need something with a larger screen, the Waveshare ESP32-P4-WIFI6-Touch-LCD-10.1 is also supported, and features a 10.1-inch display with 1280×800 resolution and a 10-point capacitive touchscreen. The actual Mac OS resolutions used are 640×360 and 640×400, respectively, then scaled twice to the native resolution of the display.Highlights of the project:
CPU – Motorola 68040 emulation with FPU (68881) — 2-3 MIPS
RAM – Configurable from 4MB to 16MB; allocated from ESP32-P4’s 32MB PSRAM
Storage – Hard disk and CD-ROM images loaded from microSD card
Display – 640×360 or 640×400 virtual display (2x scaled to 1280×720/800 physical display); 1/2/4/8-bit color depths at 24 FPS
