Sold outChecked Jul 24, 2026A2SCSI-A03by GGLABS

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.

AvailableChecked Jul 27, 2026SCSI2SD V5 Familyby SCSI2SD project and resellers

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.

AvailableChecked Jul 24, 2026Stratos SD-to-SCSI Adapter Familyby Stratos Technology

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.
