Expands eMate 300 system RAM and internal flash storage while widening both buses to 32 bits.

JCM showed 54 assembled DRAM-plus-flash modules in stock on 2026-07-24. Installing or removing this version causes a full factory reset and erases internal storage, so back up first. The developer also reports that repeated module swaps on a tester preceded lost calibration data and disabled battery charging.

Provides two switchable 8 MB flash banks that can be programmed over USB without a separate ROM programmer.

Emulates Commodore IEC devices and loads files from local flash, an SD card, or network servers over Wi-Fi.

The project provides source, several ESP32 hardware profiles, build instructions, and a browser-based firmware flasher. No direct retail source was verified, so builders must select matching hardware and firmware before connecting it to a computer.

Replaces the Atari 8-bit CPU with a 20 MHz WDC 65C816 accelerator backed by fast SRAM, SDRAM, flash, and software-selectable modes.

Both Lotharek hardware packages are discontinued. The 800XL package includes two Adaptus boards and requires CPU and OS ROM removal, socket work, a correctly oriented ribbon cable, and EXTSEL, MPD, and ground connections that differ between Freddie and non-Freddie boards. Its page says replacing DRAM with the separate SRAM module is mandatory and records additional O2 timing workarounds for Ultimate 1MB. The XE package may need four or five precision sockets to clear the cartridge slot. The official Rapidus PDF remains unavailable to automated extraction under WF-001, so obtain complete documentation before installing a used board.

Moves an SE/30 ROM onto a PDS card, bypassing the aging ROM SIMM socket and adding a bootable 2 MB ROM disk.

The store listed the PDS ROM Card at $39 with selectable flashed-ROM and chipless configurations on 2026-07-27. The vendor does not support chipless purchases because programming and ROM preparation can be difficult. A long-term installation should replace the included test clip with a soldered jumper.

Vintage VIC-20 multifunction cartridge combining configurable RAM, flash storage, SD2IEC storage, a real-time clock, and a launcher menu.

Historic Revision 11 production batches sold out. No current primary order path or complete, current fabrication package was verified on 2026-07-27, so look for a used unit and confirm its revision and condition.
