15 Euros Olimex RP2040pc Raspberry Pi RP2040 computer board supports Apple and Oric Atmos emulation

Olimex RP2040pc

Olimex RP2040pc is an inexpensive “all-in-one” computer board based on a Raspberry Pi RP2040 MCU with support for Apple //e, Apple ][+, and Oric Atmos emulation through the Reload emulator. The board features an HDMI port, stereo audio, four USB ports, and two UEXT expansion connectors. It’s not quite the first RP2040 retrocomputing board from Olimex, as they introduced the RP2040-PICO-PC in 2021 with an HDMI port, a 3.5mm audio jack, and a microSD card slot before launching the Olimex NEO6502, which combines a MOS6502 MCU for Apple II, Oric, and Commodore 64 emulators with an RP2040 for HDMI/DVI video output and a few other things. The RP2040pc is similar to the latter, but with more ports and features, and everything is handled by the Raspberry Pi RP2040 microcontroller. Olimex RP2040pc specifications: Microcontroller – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU @ 133 MHz with 264 KB SRAM Storage – 16MB […]

ESP32 Rainbow is an open-source, ESP32-S3-powered ZX Spectrum single board computer (Crowdfunding)

ESP32 Rainbow

Retrocomputing enthusiasts will be delighted to learn that a new ZX Spectrum replica is on the market: the ESP32 Rainbow. The single board computer swaps the Zilog Z80 for an ESP32-S3 microcontroller chip running an emulator, bringing the classic 80s computer back to life with a modern twist. It features a built-in color display, a microSD card slot for storage, a built-in touch keyboard in the ZX Spectrum style, and a USB Type-C port for power and data. The keyboard was recreated using full-color UV printing and is the most true-to-life component of the ESP32-S3-based ZX Spectrum single board computer. The touch keys won’t likely offer the best typing experience but that is reminiscent of the original ZX Spectrum. A lovely cherry on top is that the onboard USB-C port supports HID and the device can be used as a keyboard on another computer. The ZX Spectrum is one of […]

Sipeed Tang Mega 138K Dock is a lower-cost GOWIN GW5AST FPGA + RISC-V development board

Sipeed Tang Mega 138K Dock

The Sipeed Tang Mega 138K Dock is a low-cost version of the Tang Mega 138K Pro development board launched last year with the GOWIN GW5AST FPGA + RISC-V SoC, two SPF+ cages, a PCIe 3.0 x4 interface, and DVI Rx and Tx ports. The new Tang Mega 138K Dock keeps a GW5AST FPGA SoC but with a 484-ball package that fits on a smaller system-on-module, and does without the SPF+ cages, replaces the PCIe 3.0 x4 interface with a PCIe 2.0 x4 interface, and only uses a single HDMI port for DVI Rx or Tx. Sipeed Tang Mega 138K system-on-module Let’s first have a look at the specifications of the SoM itself: SoC FPGA – GOWIN GW5AST-LV138FPG484A with 138,240 LUT4 1,080 Kb Shadow SRAM (SSRAM) 6,120 Kb Block SRAM (BSRAM) Number of BSRAM – 340 298x DSP slices 12x PLLs 16x global clocks 24x HCLK 8x transceivers at 270Mbps to […]

Olimex NEO6502 is a W65C02 and Raspberry Pi RP2040-powered retro computer with HDMI, USB, and more

Olimex Neo6502 Dev Board

Olimex has recently launched NEO6502 an open-source hardware retro computer designed for educational and entertainment purposes, but that doesn’t mean it can’t be used for retro gaming. The board is very unique as it’s built around a 65C02 MPU and Raspberry Pi Pico RP2040 MCU in a dual-processor configuration. The MOS6502 handles the Apple II, Oric, and Commodore 64 emulators whereas the RP2040 handles everything else including HDMI (DVI) video output using the PicoDVI project. Previously we have written about similar retro computer kits such as the CERBERUS 2100, TinyLlama x86, DevTerm with ClockworkPi v3.14, Olimex AgonLight2, and many others feel free to check those out if you are interested in retro tech with a modern twist.
