Converts the digital video expansion signals from an Apple IIc-family computer or Laser 128 to an HDMI-compatible output.

JCM showed 10 assembled units in stock on 2026-07-24. The product uses an HDMI-compatible connector, but the source does not claim audio output or universal display compatibility. Power down before attaching or removing vintage-computer video adapters.

Adds RGBS and SCART video output to supported Apple II logic boards.

The kit was out of stock on 2026-07-24. Installation differs by model and requires soldering inside the computer; follow the correct PAL or NTSC instructions.

Combines the Commodore 128's separate 40-column analog and 80-column RGBI outputs into a switch-selectable SCART connection.

Retro-Updates marked revision 5.1 sold out and soon available again on 2026-07-30. The official project page still describes direct email ordering at an older EUR 22 price, but its order news is from 2021; confirm current production, price, revision, case choice, and shipping before paying. This adapter does not scan-convert the original video timing. A SCART display must accept the signals directly, or a separate SCART-to-HDMI converter is required and may produce variable results.

A passive buildable adapter that converts C128 80-column RGBI to 15 kHz analog RGB and adds monochrome composite output.

The repository publishes KiCad schematic and board files plus Gerbers. This is not a scan doubler or scaler, so the connected display must accept 15 kHz analog RGB with separate 5 V horizontal and vertical sync. The design has no CGA brown fix, does not provide VGA identification or communication signals, and will not work with a downstream converter that requires composite sync. The maker reports a successful Dell 27-inch monitor test but calls the test computer a 'C128cr'; do not infer separate C128D or C128DCR testing from that ambiguous label.

A simple buildable RGBI-to-analog-RGB adapter for 15 kHz-capable displays with a VGA connector.

The PCBWay project supplies a shared board-order path and a short component list. Assembly is required. This is explicitly not a scan doubler, so most ordinary VGA displays will not work; verify that the exact monitor accepts 15 kHz analog RGB. The maker reports a successful test with a flat Commodore 128 and an Acer G206HQL, but does not separately document C128D or C128DCR testing.

Convert the unusual HDI-45 video port on first-generation Power Macintosh systems to Macintosh DA-15 or VGA-style HD-15 output.

JCM showed five DA-15 adapters and seven HD-15 adapters in stock on 2026-07-24. The open designs remain buildable under a CC BY-NC 4.0 license. The HDI-45 pins are unusually thin and flexible, and the project strongly recommends its printed case for pin alignment and stability.

Breaks a compatible Atari five-pin monitor output into S-Video, composite video, and audio connections.

All three variants exposed login-or-register-to-buy paths on 2026-07-28. Human review established that the Atari 800, 800XL, and 1200XL have the required stock five-pin DIN connector. The Atari 400 and 600XL do not, so they are deliberately excluded. Atari 65XE and 130XE support is banked until those targets enter the catalog. Confirm that the exact regional motherboard exposes the desired luma and chroma signals before buying for S-Video use.

Breaks a compatible C64 video socket out to S-Video, composite video, and RCA audio.

The product exposed a login-or-register-to-buy path on 2026-07-28. Human review says it works only with C64 units having the compatible six-pin video socket, so it is not presented as universal across C64 revisions. Check the computer's physical socket against the seller photographs before ordering. The page's AUDIO_IN header description is garbled and is not treated as usable documentation.

Actively converts classic Macintosh DB-15 video sync signals for use with compatible VGA displays.

The BMOW store still showed the $39 Sync-inator as sold out on 2026-07-27. A monitor must still support the source resolution and scan rate.

Adapts Macintosh two-row DB-15 video to VGA with one switch for universal 640 by 480 or multiscan display modes.

The current product page offered kit and assembled configurations on 2026-07-24. A VGA cable is optional rather than included.

Adds VGA output to an Apple IIe through a compatible RamWorks III memory card.

The add-on was out of stock on 2026-07-24. It is not a standalone video card and requires a compatible RamWorks III base card.
