Recreates the Apple Disk II controller card with modern components and selectable 16-sector or 13-sector firmware.

The current CT6502 catalog offered the assembled card for direct ordering on 2026-07-24.

Recreates Apple's controller for attaching 3.5-inch Apple floppy drives to slotted Apple II computers.

The controller was available on backorder with an Add to cart path on 2026-07-24. The page says all Apple II computers, but the product is an expansion card; slotless IIc models are not attached without separate interface evidence.

Adds a two-drive floppy controller and DS1302 real-time clock to RC2014 and RCBus systems.

Tindie listed the complete Flock V2 kit without an out-of-stock notice on 2026-07-25, and open build files remain available. The CR2032 battery and optional 300 Kbit/s parts are not included. The drive-power output is unfused; avoid overloading or shorting it.

Combines SmartPort block-device support and selectable Disk II floppy-controller operation.

The base controller option was out of stock on 2026-07-24; the page still offered extension cables separately. A cable alone is not a usable controller.

Open ISA controller with two floppy controllers for up to eight drives, plus optional serial and BIOS hardware.

The assembled and tested card was out of stock on Tindie on 2026-07-25 and had been sold out since January 31, 2026. Open KiCad files, Gerbers, a bill of materials, and a manual remain available. Optional 5 V-on-pin-3 jumpers are only for compatible PS/2-style floppy drives and can damage standard drives if installed incorrectly.

Adds an Apple II-compatible environment to an IBM PC through an ISA expansion card.

The author provides complete design and fabrication files but does not sell the board. This is a large full-length card with programmed logic, RAM and ROM parts, and several required cable assemblies. It also needs the original Quadlink software disk images and DOS. The clone has been tested only in an IBM 5150; the 5160 is expected to work but remains untested by the author, and faster ISA systems may fail because the software may contain CPU-dependent timing loops.

Open ISA card combining a two-drive floppy controller, RS-232 serial port, and optional BIOS ROM.

The repository supplies KiCad files, Gerbers, a bill of materials, and assembly documentation rather than a retail order path. Install the 5 V-on-pin-3 jumper only for a compatible PS/2-style drive; using it with a standard drive causes a short. Version 1.0 also has a documented option-ROM switch-table error.

Adapts a later PLCC44 SWIM floppy controller to the DIP28 socket in an early Macintosh SE.

The current storefront listed the adapter and optional refurbished SWIM chip without an out-of-stock marker on 2026-07-24. The optional FDHD ROM pair requires a manual pin modification and is not recommended for beginners.
