| Build itChecked Jul 27, 2026 | C64 V9958 Graphics Cardby Vossi | Adds a Yamaha V9958 or V9938 video processor, 128 KB of dedicated VRAM, RGB output, sprites, and enhanced graphics modes through the expansion port. The project publishes the final 1.0 PCB, schematic, Gerbers, GAL files, documentation, and demonstration software, but no current assembled seller was verified. A build requires a V9958 or modified V9938 configuration, two compatible DRAM devices for 128 KB of interleaved VRAM, programmable logic, an EPROM or EEPROM if desired, and substantial surface-mount assembly. |

| Build itChecked Jul 24, 2026 | GW4405A 512 KB VRAM SIMMby Garrett's Workshop | Open 512 KB 68-pin Macintosh VRAM SIMM built with new 80 ns or faster memory. The assembled Tindie module was out of stock on 2026-07-24 and had been sold out since May 5, 2024. Schematics and board files remain available for commercial and noncommercial use. A 512 KB module can replace a 256 KB module where the connector is compatible, but that machine will use only 256 KB; never mix capacities within one VRAM bank. |
