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.

Replaces the Atari 800 personality module with selectable operating systems, faster floating-point code, and configurable extra memory.

The page reported four boards in stock on 2026-07-27. Functions that use $C000-$CFFF are mutually exclusive, so Omnimon and 128 KB Mosaic memory cannot be enabled together. Axlon cards require RAMROM's onboard RAM to be disabled. The optional DS1210 backup controller and coin cell are user-supplied; the seller page inconsistently calls that cell CR2032 and CR2023, so verify the fitted holder before buying a battery.

Adds 1 MB of Chip RAM, a battery-backed clock, an Indivision ECS connector, and two A1200-style clock ports to an Amiga 600.

Lotharek marks eX601n discontinued. The archived page does not document installation order, motherboard revisions, backup-battery type, clock-port orientation, power budget, or clearance with all companion devices. Inspect those details and verify any used board for battery leakage before installation.
