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.

Adapts Apple IIgs analog RGB and composite sync to a 15 kHz-capable VGA connector.

The adapter was in stock and backorderable on 2026-07-24. Most ordinary VGA monitors do not accept 15 kHz video; verify the exact display before ordering.

Generates configurable YPbPr or RGB from VIC-II bus activity with an FPGA while retaining improved composite and S-Video output.

VideoGamePerfection's EUR 60.00 kit was out of stock on 2026-07-27, but the complete open design remains buildable and upstream firmware 2.12 was released on 2026-07-03. This is a substantial soldering installation, and the original RF output is removed.

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.

Replaces the CPC 6128's six-pin video socket with a Mini-DIN 9 output wired to the Mega Drive 2 A/V standard.

Both the adapter-only and SCART-bundle pages exposed login-or-register-to-buy paths on 2026-07-27. Installation requires desoldering the original six-pin socket, soldering the adapter, connecting its 5 V wire, and wiring the AL and AR audio pads. The seller explicitly says not to remove the nearby resistors. Confirm pin orientation and display compatibility before applying power.

Converts Apple IIgs 15 kHz analog RGB to YPbPr component video for compatible televisions.

The GGLABS Tindie store was taking a break on 2026-07-24, so no current order could be placed. The display must have component inputs and explicitly accept 240p; GS2HD does not upscale the IIgs signal to a modern scan rate and does not provide HDMI.

Adds digital RGB, optional 31 kHz scandoubling, display corrections, and an 80-column overlay while retaining the original GTIA.

The product exposed a login-or-register-to-buy path on 2026-07-27. Update its initial firmware before installation. A socketed GTIA may still require careful removal of the adapter's bottom socket for height; a soldered GTIA must be desoldered. The May 2026 hardware manual is explicitly a draft. The product page publishes a complete VGA pinout but leaves the 15 kHz connection diagram unfinished, so do not improvise a SCART or RGB-monitor cable from that page. SECAM computers use an incompatible FGTIA pinout and are not supported.

Automatically selects among five, eight, or sixteen powered SCART sources, with expandable Hydra2 variants providing as many as 24 inputs.

The Hydra2, W-Hydra2, W-Hydra, both Mini Hydra cases, and HEADS pages exposed login-or-register-to-buy paths on 2026-07-27. Mini Hydra cannot use HEADS. Hydra2 and W-Hydra2 can reach 24 inputs; W-Hydra can reach 24 inputs but has one output. Use simple correctly attenuated 75-ohm source cables. Do not feed TTL-level sync into an analog input, and never connect or disconnect SCART while the switcher or source is powered because the seller warns that hot-plugging can damage the video-switch IC. Power hardware is separate: most Hydra2 variants accept 5 V Micro-USB, selected variants also accept the separately sold 9 V PWR4, and the older W-Hydra page specifies 5 V Micro-USB.

Converts Apple III or compatible Apple IIe TTL RGB to CGA-style and Apple IIgs-monitor outputs.

The current page offered a fully assembled option on 2026-07-24. It does not work with the Apple IIc. An Apple IIe Extended 80-Column RGB Card needs the documented jumper installed near its video header.

Adds RGB color, programmable sound, paged memory, a Forth extension ROM, and serial I/O to the Jupiter II computer.

A2Heaven marked the expansion kit out of stock on 2026-07-27. The historical package included the expansion PCB, active and passive components, pre-mounted SMD parts, placement and schematic diagrams, documentation, and source material. The base Jupiter II computer was separate and also out of stock.

A current ZX Spectrum-compatible motherboard for an original 48K or Spectrum+ case, with real and FPGA Z80 modes, 512 KB of RAM, enhanced video, and extensive audio.

The assembled and tested Revision 1.5C motherboard exposed an order path on 2026-07-27. It requires a separate original 48K or Spectrum+ case, keyboard membrane, video cable, display, and 9 V AC or DC supply rated for at least 400 mA with the documented 2.5/5.1 mm plug. Power polarity does not matter. Lotharek separately sells its 9 V, 1.5 A PWR4 for KRAKEN, without a country-specific mains lead. The page's layout drawing shows Revision 1.5B, which differs slightly. External DivMMC or DivIDE hardware may not work in turbo modes.

Converts composite, S-Video, RGB, RGBI, and VGA-family retro signals to simultaneous digital and analog DVI-I output.

The European SCART and Japanese JP21 Revision B pages exposed login-or-register-to-buy paths on 2026-07-27. Never connect an EU SCART cable to the JP21 version: the seller says the different pinout can damage the device. The newest dated hardware announcement says units made since June 2025 have a larger OLED and USB-C power, but an older section still says Micro-USB. Human review found no package clarification, so confirm the connector, power requirement, and included USB items with the seller. A DVI-to-HDMI cable and source-system cables are sold separately. Medusa line-doubles when needed but does not change vertical refresh rate, so the destination display must accept the resulting 50 or 60 Hz signal and may blank briefly when the source changes resolution. Install only firmware matching the hardware revision.

Converts Sophia or VBXE RGB video to VGA inside a 1088XLD.

The project publishes schematics, Gerbers, source, and PIC12F1572 firmware, but requires a separate GBS-8200 board and mechanical installation. Firmware 1.2 is beta, high-resolution modes are untested, and its rudimentary presets do not work with every monitor. The maker notes that Sophia2 is generally the better universal VGA and DVI solution.

Adapts a SCART video connection to the BNC inputs used by Sony PVM, BVM, and similar professional monitors.

The page exposed a login-or-register-to-buy path on 2026-07-27. The seller describes a connector adapter and included BNC cables, not a scaler or format converter. Confirm the SCART cable direction, signal levels, sync wiring, source timing, and the exact monitor inputs before use.

Replaces the ULA, video RAM, upper RAM, and RF modulator in Issue 2 through 6 ZX Spectrum 48K boards while adding modern video, sound, memory, and machine modes.

The seller listed availability after 2026-08-31 and exposed a preorder path on 2026-07-27. Installation is invasive: remove the ULA and RF modulator, disable or remove the original DRAM, connect M1, RESET, IORQ, and RFSH at the Z80, and install the supplied RGB adapter and ribbon cable. The output is digital RGB only, not composite or YUV. Verify board issue, pin 1, wiring, case clearance, display compatibility, and the current installation guide before work.

Adds RGB output, enhanced graphics modes, a blitter, and true 80-column text to supported Atari 8-bit computers.

The XL and XE product pages both exposed login-or-register-to-buy paths on 2026-07-27. Choose the machine variant deliberately: both storefront descriptions say an XE adapter is included, but the installation manual explicitly says the XL and XE ANTIC adapters differ. Installation requires ANTIC removal, an adapter soldered to the motherboard, several model-specific signal connections, and an EXTSEL safety check that may require modifying a Freddie pin. The current manual documents 800XL, 800XLF, XE, and XEGS paths, not 600XL or 1200XL.

Replaces a breadbin C64 VIC-II with an FPGA implementation offering configurable video, extra VRAM, new graphics modes, and optional digital or RGB output.

Official distributor VideoGamePerfection offered Mini and Large boards for EUR 74.95 to EUR 103.95 with an Add to cart path on 2026-07-27. The maker warns that some Large boards shipped by VGP with firmware 1.17 contain a DVI-instability bug and should be reflashed with the corrected 1.17 image.
