Period slot memory and bootable RAM-disk card with optional expansion and battery backup.

This is the original period product, distinct from modern RamFactor-compatible cards. Used examples vary by board revision, installed memory, expander, ROM, and included software. It normally uses a peripheral slot other than slot 3; an Apple II Plus must not use slot 0. The IIgs treats it as RAM-disk storage rather than fast system memory. Verify any RamCharger, cable, and old battery hardware before applying power.

Provides selectable Apple Slinky or RAMFactor-compatible memory using modern low-power SDRAM.

The assembled Tindie card was out of stock on 2026-07-24 and had been sold out since January 23, 2025. Schematics, board files, CPLD firmware, utility software, and fabrication files remain available under the project's dual-license terms.

Modernizes the Applied Engineering RAMFactor design with 1 MB or 8 MB of low-power Slinky RAM and battery-backed storage.

The 1 MB version showed one unit in stock on 2026-07-24; the 8 MB version was out of stock. A CR2032 is required for battery-backed use and is explicitly omitted from the 1 MB package because of postal restrictions.

Open 1 MB battery-backed RAMFactor-compatible memory card with a NoSlotClock-compatible clock and ProDOS restore image.

No current assembled seller was verified on 2026-07-24, but the GW4206B hardware, CPLD, firmware, documentation, and fabrication files remain public. A CR2032 is required for clock operation, retained RAM, and the restore partition. Replacing it erases RAM and resets the clock. Disable TimeDisk's clock when another NoSlotClock-compatible device is present. The USB updater requires 64-bit Windows 10 or later, including supported Boot Camp or Parallels configurations.
