• Macintosh SE/30 Bus/interface

Recreates the circa-1990 AdLib OPL2 FM-synthesis sound card as a buildable open hardware project.

This is a self-assembly reproduction rather than a currently sold assembled card. The repository has no packaged release; use the project files and parts list directly.

• ISA expansion boards Bus/interface

Modifies an Amiga 1000 to boot Kickstart from four EPROMs while retaining access to its 256 KB daughterboard RAM.

This is an advanced board-level modification, not a plug-in board. It requires a GAL16V8A, four 27C512 EPROMs, a legally obtained Kickstart image, device programming, desoldering, jumper installation, and PCB trace cuts.

• Amiga 1000 Exact model

Recreates the Comspec SA-1000 sidecar to add a SCSI bus and real-time clock to an Amiga 1000.

This is a self-assembly project with a schematic, bill of materials, and fabrication package. It requires programmed GALs and ROMs plus careful alignment of the 86-pin edge connector. The alternate RTC-72421 clock chip is suggested but untested.

• Amiga 1000 Exact model

Open hardware expansion card that generates 640x480 VGA and implements the Apple IIe's native text and graphics modes.

• Apple IIe Exact model

Connects a modern Mac to Apple and PC floppy drives for disk imaging, flux capture, analysis, and writing.

The official store marked Applesauce+ sold out on 2026-07-15. The client requires macOS 10.13 or later; Windows and Linux use requires macOS virtualization. Current boards use a 12V adapter, and the power adapter and PC-drive cables are sold separately. Flux imaging with Apple-compatible 5.25-inch drives requires a sync sensor, which is also strongly recommended for Apple 3.5-inch drives; PC drives do not need one.

• Floppy preservation hardware Bus/interface

Period accelerator card offered with a 65C02 or 65802 processor and 256K of high-speed memory.

This is a period product obtained used. Confirm the exact TransWarp revision and installed processor before buying.

• Apple IIe Exact model

Recreates the Gravis Ultrasound PnP ISA sound card around an AMD InterWave chip, with an optional IDE CD-ROM interface.

The maker has not fabricated or tested this board and has not generated a fabrication package. It also requires an AMD AM78C201 InterWave chip. Treat it as an experimental design and build at your own risk.

• ISA expansion boards Bus/interface

Open hardware SCSI emulator that uses disk images on an SD card as replacement storage for vintage computers.

• Macintosh SE/30 Exact model

Runs a 68030 CPU and 68882 FPU at 47 MHz for roughly twice the overall performance of a stock SE/30.

• Macintosh SE/30 Exact model

Uses an SD card to emulate Apple floppy drives and, on supported systems, HD20 or SmartPort hard disks.

The BMOW store showed this model as sold out on 2026-07-14. Check the direct product page for a restock.

• Apple IIe Exact model
• Macintosh SE/30 Exact model

A DIY USB floppy interface and cross-platform toolkit for reading and writing unusual disk formats with a conventional PC floppy drive.

Building the original interface requires a compatible PSoC 5 development board, a floppy connector, soldering, a conventional PC floppy drive, cabling, and drive power. The project warns that not every listed format has been tested on physical disks; its dinosaur markers identify encoders or decoders based only on captured data. Copy-protection schemes are not a core focus.

• Floppy preservation hardware Bus/interface

Adds Wi-Fi networking and platform-specific peripheral emulation to several vintage computer families.

The project lists small-batch hardware vendors and open design files. Stock and the required hardware variant vary by platform and seller.

• Apple IIe Exact model
• Atari 800XL Stated family

Provides MDA and CGA-compatible display modes with 31 kHz VGA output for modern monitors and capture devices.

This is a self-assembly project. The maker advises checking for shorts between each power rail and ground before installation; the oscillator configuration also affects CGA composite color accuracy.

• ISA expansion boards Bus/interface

Connects a modern computer over USB to a separate floppy drive for reading, analyzing, and writing disks at the raw flux level.

An assembled board still needs a compatible Shugart-interface floppy drive, ribbon cable, USB cable, and suitable drive power. Older 5.25-inch and 3-inch drives often need 12V or a separate supply. Remove the write-enable jumper while preserving originals. Apple II, Macintosh, and Commodore 64 GCR disks can require trial and error with drive choice.

• Floppy preservation hardware Bus/interface

Open hardware reproductions of the two interface cards used to connect an IBM PC or XT to a 5161 Expansion Unit.

• ISA expansion boards Exact model
• IBM Personal Computer 5150 Exact model
• IBM Personal Computer XT 5160 Exact model

Adds CompactFlash and ATA or ATAPI mass storage plus USB PCLink transfers to a Commodore 64 expansion port.

The official project site is active and identifies V4.2 as the latest revision, but the selected official pages provide neither a current order path nor a complete fabrication package. Check the used market and confirm the hardware revision before buying.

• Commodore 64 Exact model

Provides two switchable 8 MB flash banks that can be programmed over USB without a separate ROM programmer.

• Macintosh SE/30 Exact model

A USB floppy controller and host-software package for forensic-quality flux capture, analysis, image conversion, and disk writing.

The official site offers hardware to private and hobby users through its web store. Host software is free only for private, personal use; commercial and institutional users, including libraries, archives, and museums, need a separate license. The current macOS GUI requires Rosetta 2. Consult the current manual before selecting and powering a drive.

• Floppy preservation hardware Bus/interface

Current 8-bit ISA adapter that lets a CompactFlash card serve as an XT-IDE hard disk in an IBM PC or XT-class computer.

• ISA expansion boards Bus/interface
• IBM Personal Computer 5150 Bus/interface

• Macintosh SE/30 Exact model

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

The BMOW store showed the Sync-inator as sold out on 2026-07-14. A monitor must still support the source resolution and scan rate.

• Macintosh SE/30 Bus/interface

Redesigns the SE/30 logic board as a buildable replacement with Gerbers, placement data, a BOM, and recreated programmable logic.

• Macintosh SE/30 Exact model

Emulates Commodore IEC devices and loads files from local flash, an SD card, or network servers over Wi-Fi.

The project provides source, several ESP32 hardware profiles, build instructions, and a browser-based firmware flasher. No direct retail source was verified, so builders must select matching hardware and firmware before connecting it to a computer.

• Commodore 64 Exact model

Period 68040 accelerator originally made for a Macintosh IIci cache slot and usable in an SE/30 only through a specialized adapter.

Use only a proven SE/30-to-IIci cache-slot adapter and the patched software. Never insert this card into a PDS slot or PDS pass-through: the connectors fit but are electrically different, and a wrong connection can destroy the accelerator.

• Macintosh SE/30 Exact model

Recreates the 16 MHz 68030 MicroMac Performer accelerator for the Macintosh Plus, SE, and Classic, with an optional 68882 FPU.

Operation has been tested in the Macintosh Plus and SE, but not in the Classic; the maker has not found a socket that securely fits over the Classic's PLCC CPU. Host-specific U7 and SJ2 settings are mandatory. GAL16V8-15 and PALCE16V8-15 parts are tested, while ATF16V8 and other speeds are not.

• Macintosh Plus Exact model
• Macintosh SE Exact model
• Macintosh Classic Exact model

Combines an approximately 16 MHz 68030 and optional 68882 on a compact MicroMac Performer remix made for a Macintosh Plus clone.

The only documented Revision 2 installation is in a Macintosh Plus clone. The author expects an original Apple Macintosh Plus to work but asks users to report results, so stock hardware remains unverified. Installation requires desoldering and socketing the 68000, PLD choice is important, and some software may have distorted audio.

• Macintosh Plus Exact model

Modernizes the Mockingboard A sound card with six voices, a 3.5 mm output, and an input for the Apple II motherboard audio.

• Apple IIe Exact model

Period accelerator that upgrades a 4.77 MHz 8088 IBM PC or XT with an 8 MHz 80286 processor and 8K of cache.

This is a period product obtained used. The documentation project cannot produce a working clone until the original PAL devices are reverse engineered.

• IBM Personal Computer 5150 Exact model
• IBM Personal Computer XT 5160 Exact model

Current multifunction 8-bit ISA card that adds emulated storage, memory, networking, and USB or SD-connected devices to PC/XT-class computers.

• IBM Personal Computer 5150 Bus/interface
• IBM Personal Computer XT 5160 Bus/interface

Adds a 16 MHz 68030 to a Macintosh Plus with a compact hobbyist-buildable board derived from the MicroMac Performer.

This build requires a PGA 68030, five programmed 16V8 devices, and soldering a socket on top of the Macintosh Plus 68000. The maker does not recommend the System 7.0 GemStart driver, reports garbled or intermittent audio, and warns builders to watch the first SIMM's clearance.

• Macintosh Plus Exact model

Open hardware 10/100 Ethernet card designed around a modern controller for the Macintosh SE/30 PDS.

• Macintosh SE/30 Exact model

Recreates the 1989 Sound Blaster 1.0 with digital playback and recording, AdLib-compatible synthesis, CMS audio, and a joystick/MIDI port.

This is a self-assembly project. Follow the documented bodge resistor, MIDI jumper-wire, firmware, DMA, IRQ, joystick, and I/O-address instructions before use.

• ISA expansion boards Bus/interface

Implements Sound Blaster-compatible audio for Micro Channel systems with OPL2 synthesis and CPLD-managed bus, interrupt, and DMA logic.

Installation requires the supplied ADF and the host reference-disk configuration program. The maker warns against LS or HCT logic because it may not meet Micro Channel timing margins.

• Micro Channel expansion boards Bus/interface

Connects a modern computer or serial controller to a 34-pin floppy drive for low-level flux capture, analysis, and disk duplication.

The official page says "Advanced Version Coming Soon!" and does not expose an unambiguous current order path, so availability needs a human check. SuperCard Pro requires a PC-compatible 3.5-inch or 5.25-inch drive, a 34-pin cable, and suitable drive power; Amiga 3.5-inch drives are explicitly incompatible. Floppy-emulator firmware described as planned is not treated as a current feature.

• Floppy preservation hardware Bus/interface

Replaces a Commodore 64 motherboard with an FPGA-based board offering modern video, storage, networking, and emulated peripheral functions.
