Combines a 14 MHz 65816 accelerator, 14 MB memory expansion, HDMI output, RAM disk, and SD-backed drives for the Apple IIgs.

The regular AppleSqueezer GS v2 listing was out of stock on 2026-07-24. A separate preorder tile remained visible, but an active preorder order path was not verified; check the shop or mailing list for another production run.

Adds CompactFlash storage to an Apple-1 or a compatible clone.

ReActiveMicro showed the CFFA1 in stock with backordering enabled on 2026-07-27. The supplied package includes a CompactFlash card and software. It does not work in Apple II systems.

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.

Replaces the Apple III boot ROM so SOS can boot directly from compatible ProDOS block storage.

JCM showed eight programmed replacements in stock on 2026-07-24. Existing boot images are not automatically compatible: users must install the project's modified boot loader, SOS.KERNEL, and drivers or use a prepared image. The ROM normally searches slots 4 through 1 for a ProDOS block card and falls back to the internal floppy.

Adds SD mass storage to Commodore 264-series computers and can replace the paddle cartridge in a real 1551 drive.

The repository provides Gerbers, firmware, hardware instructions, and release files sufficient for a DIY build. The maker invites requests for a completed unit but does not advertise standing stock. Disk images are read-only, and the device does not reproduce a 1551 exactly. When a TCBM cable is fitted, both specified ground pins must be connected as documented.
