Open RTL8019 Ethernet card that brings NE2000-compatible networking to 8-bit ISA computers.

The fully assembled card was out of stock on Tindie on 2026-07-25 and had been sold out since December 15, 2025. Open KiCad files, Gerbers, software, and a separate bare-PCB path remain available. A DIY build needs a unique valid MAC address and surface-mount RTL8019 assembly.

Builds a compact modular IBM PC/XT-compatible computer with an 8088 or NEC V20, up to 640 KB of base RAM, optional upper memory, and 8-bit ISA expansion.

The GPL-3.0 project provides KiCad files, Gerbers, a bill of materials, BIOS, programmable-logic files, and build instructions. Retro Electronics had six bare ENIG PCBs in stock on 2026-07-27; every component and all assembly are excluded. Weird Electronics' board and complete-kit listings were temporarily unavailable while the seller takes a break through August 20, 2026. A separate assembled-board listing had been sold out since May 11, 2026. Weird Electronics sells a Version 1.4 PCB with larger Flash-ROM support, while the repository README documents layouts through Version 1.3; follow the documentation for the board actually supplied.

Open 8-bit ISA real-time clock card for PC/XT systems without a built-in battery-backed clock.

Weird Electronics' assembled, complete-kit, and PCB-plus-programmed-SPLD options were temporarily unavailable while the seller takes a break through August 20, 2026. Aitor Gomez Garcia's low-profile version showed three units in stock on 2026-07-27 but currently ships only within Spain. A CR2032 battery is not included.

Open Trident TVGA9000i VGA card for 8-bit ISA computers, including the original IBM PC and XT.

Use PCB version 1.1 for an original IBM PC or XT; version 1.0 needs the documented ALE rework. On version 1.1, the C17 silkscreen incorrectly says 1 uF instead of 1 nF. The project also documents a color-monitor detection workaround for newer DDC displays.
