Tag: 80 column

Provides 80-column text over HDMI from a Raspberry Pi Pico card installed in a 1090XL-family expansion system.

The page reported three cards in stock on 2026-07-27. A 1090XL or 1091XL base system and a separate HDMI display are required. Enabling the card disables normal video output; holding Shift while booting disables the card. Each installed expansion card needs its own jumper-selected device ID.

Converts Commodore 128 80-column RGBI into 15 kHz analog RGB for a compatible display or a separate VGA scaler.

The official site says sales resumed through its Square store in January 2024, but current stock was not independently confirmed on 2026-07-30. BIT-C-128 is not a scan converter: direct use requires a display that accepts roughly 15.75 kHz analog RGB. An ordinary VGA display also needs a GBS-8200, GBS-8220, or another suitable scaler. Supply regulated 5 V power and the cables or adapters required by the selected display path.

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.

Converts the C128's 80-column digital RGBI output to analog RGB and composite sync for a separate video scaler.

Protovision reported eight units in stock at EUR 30 on 2026-07-30. This adapter converts signal levels and combines sync but does not raise the scan rate. Its documented setup uses a separate GBS-8200 or GBS-8220, which is not included. Follow the page's normal/inverted-sync procedure if GBS auto scan does not lock cleanly.

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.

Combines a Commodore 128's 40-column and 80-column video paths in one switchable external adapter.

Pyrofer's Projects lists the NTSC board and its separate C128DCR mounting tab as out of stock. The normal package uses tabs for the flat C128 and standard C128D; the differently spaced C128DCR requires the separate tab. Although the board has a PAL/NTSC selection, the seller says changing format also requires a different oscillator IC, and the listed package includes the NTSC oscillator.

Converts digital RGBI into 15 kHz analog RGB and can break out a Commodore 128's 40-column S-Video and audio.

The maker lists the assembled board as out of stock and publishes no fabrication package. This is not a scan converter; the display must accept the source timing, normally about 15 kHz, or use a separate scaler. The maker's design history says the completed logic omits the valid intensity-only dark-gray color, which appears black. The board also passes 5 V to HD-15 pin 9; verify that the attached cable and display do not ground that pin.

Current switched cable variants for using the C128's 40-column analog video and 80-column RGBI output with one display setup.

Both Tindie pages exposed current prices and ordering controls on 2026-07-30; the premium version explicitly reported three units left. Shipping depends on the selected destination, and no rate was shown during extraction. The seller documents a shielded cable, an onboard micro PCB, and an operating LED. No scan conversion is documented, so confirm that the intended display accepts the cable's original-timing composite, S-Video, and SCART RGB signals.

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.

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.

C64 cartridge that provides an 80-character text display and is intended for use with a modern flat-panel display.

Poly.play listed Highspeed80 at 17 EUR, available immediately, on 2026-07-30. The seller gives a normal German delivery estimate of 3 to 10 working days and notes that international delivery can differ. The product page recommends a TFT display.

Replaces a failed Commodore PET motherboard with a modern 32 KB board supporting selectable 40- and 80-column modes, several BASIC versions, and original PET interfaces.

Tynemouth Software's active Tindie listing offered revision 1.84B as either a through-hole self-assembly kit or a built and tested board on 2026-07-27. International buyers are instructed to contact the seller for a shipping quote.

Converts an Apple IIe 80-column card into a 64K auxiliary-memory card.

The current product page listed the complete kit without an out-of-stock marker on 2026-07-24. The included used TMS4464 DRAMs are free, unguaranteed bonus parts and may need replacement.

Recreates the Applied Engineering RamWorks III memory and 80-column card for the Apple IIe.

The store currently lists this 64K self-assembly kit as out of stock. It includes the PCB, parts, and assembly diagram and requires soldering.

Adds 8 MB of auxiliary-slot SRAM and battery-backed storage to an Apple IIe.

The assembled card was out of stock on 2026-07-24. It is a complete auxiliary-slot card, not the PiggyBack8M add-on for a separate RamWorks III.

Expands a 64K Apple IIe to 128K through the auxiliary slot and provides 80-column memory.

The current Infinity Products storefront listed the card with a direct product page and no out-of-stock marker on 2026-07-24.

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.

Adds an 80-column text display to Atari 8-bit computers, with composite output and an optional HDMI conversion path.

The Brewing Academy collection marked XEP80-II sold out on 2026-07-24 even though its product description still called the units build-to-order. The listed DIY option supplies a bare main board with a tested NS405; assembled and cased options were also described. A separate listing offers programmed OS and character EEPROMs for DIY builders. The HDMI converter needs separate Micro-USB power. Unlike Atari's original XEP80, XEP80-II has no parallel printer port.
