Recreates Apple's Revision C SCSI card with termination power and onboard active termination for improved drive compatibility.

The GGLABS Tindie store says the seller is taking a break and offers a return notification rather than a current order path. The project page provides software and technical material, but says parts of its pseudo-DMA and IIgs-mode schematic documentation remain incomplete.

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.

Open hardware SCSI emulator with SD-backed storage, optional Wi-Fi networking, and host-side management tools.

Current seller checks on 2026-07-27 found a $39 internal 50-pin Pico 2 W kit, a $49 assembled external DB-25 model, a $49 PowerBook model, and a $59 assembled Ultra Narrow 50-pin model at authorized seller ToTs RETRO. JCM also carried assembled Ultra hardware and model-specific Macintosh adapters. Prices, stock, included media, and support differ by seller. Ultra models require Berg or Molex power and cannot run from SCSI termination power. The initial Ultra hardware release is not yet open hardware, although its firmware remains GPL; the project says hardware licensing will open later.

Adds an internal SCSI connection and termination power to a Macintosh Plus by clipping over its SCSI controller chip.

The JCM page showed 18 units in stock on 2026-07-24. Installation requires opening the compact Macintosh, removing and reinstalling its logic board, routing a SCSI cable through a tight chassis gap, and supplying a separate SCSI device.

Connects one CS/A65 expansion card to a Commodore 64 expansion port or beneath a PET's socketed 6502.

The C64 revision 1.0C is marked okay and publishes Eagle files, but it works only with the C64, not the C128, and a fitted CS/A card can conflict with long video or IEC plugs. For PETs, revision 1.1A was tested only in a CBM 8296 and had power and clearance problems. Later 1.2A and 1.2B layouts add 3.3 V power and more mounting options but are explicitly untested. A working 8296 Ethernet stack is documented. usb65 later lists PET plus adapter plus NetUSB 1.x as tested, although the older NetUSB page says its single PET-adapter test was not fully working and suspected a supply problem. Treat that USB path as experimental. No current assembled seller was verified.

Replaces or upgrades the custom logic and serial clock parts on an existing EMPLANT Amiga expansion board.

All three parts were in stock on 2026-07-24. These listings do not include an EMPLANT board. The P3 page says an A- or B-model board also needs other necessary parts to become a C model, but it does not provide a complete conversion kit or parts list; inspect the existing board and original manual before buying.

Converts the Macintosh Portable's internal 34-pin SCSI connection for a 2.5-inch notebook SCSI device.

The product page exposed a current Add to cart control on 2026-07-24. SD PowerMonster is a separately listed product.

Multifunction 50-pin SCSI-2 device that emulates hard disks and CD-ROM drives from SD or MMC media.

The Tindie page exposed quantity and CD-audio-jack selectors with a current View Options and Buy path on 2026-07-24. Its destination-dependent shipping messages were inconsistent, so buyers should confirm shipping for their country.

Extends a Macintosh rear DB-25 SCSI port so a DB-25 BlueSCSI can connect with usable clearance.

Both kit and assembled configurations had a live Add to Cart control on 2026-07-24. A BlueSCSI device is not included.

Period high-speed SCSI controller with an onboard processor, DMA, cache, and ROM-based disk utilities.

This is a period controller obtained used. Confirm whether the board is Revision C or D and which ROM it runs. Revision D does not use DMA in a IIe, while Revision C needs its documented IIe switch setting. SCSI ID, termination, terminator power, cable length, drive power, and backups all require care. Compatibility problems are documented with some accelerator and memory-card combinations; ROM 3.01E and 3.01EZ have a tape-restore bug corrected in later firmware.

Adapts several common vintage SCSI connectors while eighteen LEDs expose signal activity for testing and troubleshooting.

JCM showed 34 units in stock on 2026-07-24. Connector orientation matters: align the PowerBook connector's marked missing pin, install the Centronics connector with its wider side toward DB-25, and expect the internal 50-pin female socket to be unusually tight.

Mounts a BlueSCSI or another 50-pin SCSI device directly above a Macintosh internal SCSI connector.

The current store page listed partly assembled and complete options without an out-of-stock marker on 2026-07-24. The maker repository also provides assembly material and Gerbers.

Connects a 50-pin SCSI device such as BlueSCSI V2 directly to an external Macintosh DB-25 SCSI port.

The store page explicitly said Out of Stock on 2026-07-24, but the maker repository includes assembly instructions and Gerbers for noncommercial DIY fabrication.

Adds SCSI disk hardware to a Commodore 64 through a CS/A adapter, with experimental external IEC-drive variants.

Only the modular C64 CS/A adapter plus CS/A SCSI card combination is reported tested and working. The simplified combined C64 board was not fully checked. VC-SCSI 1.0's component boards were tested separately but not as a complete drive, VC-SCSI 1.x remained an idea, and VC-SCSI 2.x was preliminary and untested. The published FAT12/FAT16 filesystem software is explicitly early beta and may corrupt a disk; never test it with valuable media. No current kit or assembled seller was verified.

Retired family of SD-backed SCSI drive emulators that includes internal 50-pin and direct-attach DB-25 hardware.

Upstream describes SCSI2SD V5 and V6 as permanently retired. SamplerZone nevertheless exposed an Add to Cart path for a cased v5.5 at $129.95 on 2026-07-27, including configured microSD media and optional HD50 or Centronics-50 adapters. Treat v5.1 as a used-market mechanism upgrade and confirm reseller fulfillment for v5.5. The documentation hub lists v4.8.4 from 2019 as the latest firmware for both versions. V5.5 has fixed termination and must be last on its chain; hosts without DB-25 termination power need USB power.

SD-card storage adapters for notebook SCSI, internal 50-pin SCSI, and external DB-25 SCSI connections.

The standalone PowerMonster, AztecMonster, and SusanoMonster pages exposed current Add to cart controls on 2026-07-24. The external PowerMonster with BakMonolith kit was out of stock. Mac OS installations need suitable third-party formatting software. Hot swapping works only when the host operating system supports removable media and may require explicit unmount and mount operations.

Open-firmware SCSI emulators in DB-25, internal 50-pin, laptop, and Wide SCSI form factors.

Rabbit Hole Computing offered current Compact RP2040, Blaster, and Wide variants on 2026-07-24. A 2026-07-27 follow-up found its mostly assembled $25 Pico Slim V1.3 PCB kit sold out, while SamplerZone exposed an Add to Cart path for a $79.95 assembled and cased Pico Slim with configured microSD media. Rabbit Hole's direct Pico2 Slim and Laptop Blaster pages were also sold out. TinySCSI was archived in January 2025, but its V1.0 and V2.0 KiCad files remain available for personal builds. A project discussion documents Wi-Fi DaynaPORT operation on a Pico Slim under System 7.5.5 with the DaynaPORT SCSI-port driver, but does not establish a minimum System version or equivalent networking support for every family variant. Connector, termination, power, speed, and initiator support vary by hardware.
