ethernet10base trj 45new old stock

Connects a Macintosh AAUI Ethernet port to twisted-pair 10BASE-T through an RJ-45 jack.

Joe's Computer Museum showed 29 new-old-stock PN512B units in stock on 2026-07-24. They are sold as-is without warranty. A modern gigabit-only switch may not negotiate 10BASE-T; the seller recommends a switch with explicit 10/100 support.

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.
