amen zwa, esq.Those who learned #computing in the 1970s and 1980s—from the signal-level up, on trainers like KIM-1 or Heathkit ET-3400—often get the urge to stroll down Memory Lane, the full 256-byte length of it. They need not spend thousands of dollars on eBay to purchase a beaten, broken, fifty-year-old trainer; they could just grab the wonderful Black Pill #STM32 F411 Cortex board on #AliExpress for $0.99.

Or, try the fabulous #ESP32 C3 RISV-V board, with an OLED display, WiFi, and BLE for the same amount of money.

These thumb-sized #MCU boards are more capable than the 1980s room-sized super-minicomputers. The F411, for example, has a 32-bit 100 MHz Cortex-M4F with FPU, 256 KB SRAM, and 512 KB Flash.
These boards can be programmed in assembly or the usual assortment of open-source, higher-level #programming languages, like Forth, C, C++, Go, Rust, Zig, Ada, etc., and even Processing, Python, and JavaScript.
A good selection of open-source #RTOS are available, too: FreeRTOS, Zephyr, ChibiOS, and the like.
Go ahead; by a bucket load of MCU boards from AliExpress, relive those happier simpler times, and simultaneously buck the stupid #tariffs.
MontyOnTheRunNow, with textures on a regular Pi #Pico (non-W), running on top of Apache #NuttX #RTOS
You could say now that Apache NuttX kinda, sorta, almost, but-not-really supports #OpenGL ES 1.0 CL (albeit in a very incomplete form).
There are some bugs with the colour and lighting interpolation, so while it's computed, the contribution towards the final fragment were discarded.
Also, the display is a different one, ST7735S-based, since it play nicer with NuttX.
Florian KromerZepyhr RTOS (MCU OS) has support for WireGuard VPN now 🔒
„The networking stack also gains support for WireGuard VPN, enabling secure, low-overhead tunneling directly on your Zephyr devices. WireGuard is known for its simplicity, speed, and strong cryptography, making it an ideal fit for resource-constrained embedded devices that need secure remote management or encrypted data transport.“

Nuvoton NuMicro M3331 Cortex-M33 MCU features built-in ARGB LED controller, optional USB 2.0 OTG interface
Nuvoton's new NuMicro M3331 is a series of 32-bit Arm Cortex-M33 MCUs clocked at 180 MHz that integrate an ARGB LED controller, a DSP instruction set, a single-precision FPU, and TrustZone security for smart factories, renewable energy systems, and consumer devices. In the past, we have written about other Cortex-M33 MCUs like the STM32U3B5/C5, Texas Instruments MSPM33C321A, Nordic Semi’s nRF54LM20A, and various others, but the Nuvoton M3331 series specifically features a built-in Enhanced LED Light Strip Interface (ELLSI) and up to 10 standard LLSI channels. This allows the MCU to natively support gaming ARGB Gen1 and Gen2 LED control protocols, completely offloading the CPU to run fluid, dynamic LED effects. It comes in two variants, the M3333 series and the M3334 series, with the latter adding a high-speed USB 2.0 OTG controller with an integrated PHY. NuMicro M3331 specifications: MCU core – Arm Cortex-M33 32-bit CPU @ 180 MHz with single-precision

Microchip SAM9X75 Hybrid automotive MCU – Surprisingly ARM9 is still a thing in 2026
Microchip SAM9X75 Hybrid automotive MCU – Surprisingly ARM9 is still a thing in 2026
When Microchip launched the SAM9X60 in 2020, we were surprised to see a new SoC based on a legacy ARM926EJ-S core. But we were even more surprised to see Microchip doubling down with the SAM9X75, a hybrid automotive-qualified (AEC-Q100 Grade 2) System-in-Package (SiP) with the same classic ARM9 core and integrated DDR2 or DDR3L memory. The first part will be the SAM9X75D5M SiP with 512MB on-chip DDR2 RAM, but the company also designed the SAM9X75D1G with 1 Gbit DDR3L and the SAM9X75D2G featuring 2 Gbit DDR3L. The SAM9X75 hybrid ARM9 MCU targets developers who need an MCU-like development environment, while benefiting from higher processing and display capabilities of microprocessors for automotive and e-mobility HMI applications. Microchip SAM9X75D5M specifications: CPU subsystem Core - ARM926EJ-S running up to 800 MHz (significant increase from older 400-600MHz variants) 32 KB data cache, 32 KB instruction cache, and Memory Management Unit (MMU). Memory 512 Mbit
