DIY replica of the 1985 C64 freezer cartridge that captures RAM, I/O, and CPU state to disk.

The replica repository's 2021 v1.0a files include ISEPIC-named Gerbers, an Altium PCB project, schematic, bill of materials, and disk images. Its README mistakenly links its PCBWay order button to a different 8 MHz Z80 card; do not order that board as an ISEPIC. Review and fabricate from the included ISEPIC files instead. Replica hardware files outside the Docs and Software directories are CC BY-NC-SA 4.0. The original 1985 ISEPIC software remains copyrighted and is not covered by that hardware license.

c64c128cartridgefreezersnapshotdisk toolstapeepromgerbersdiyvintage

Vintage and DIY C64 freezer cartridge that saves restartable memory snapshots to disk, tape, or EPROM-oriented cartridge files.

DDI's Re-Capture page still exposes Gerbers, a parts list, a Capture ROM archive, and a manual link. The parts list specifies the EPROM, SRAM, logic, passives, and switch choices, but ReplayResources says the schematic is still missing and no complete assembly or test guide was found. Neither page supplies a clear license for the reproduction files or Capture software. ReplayResources quotes permission relating to Jason-Ranheim's separate Promenade materials but explicitly says its own Capture permission requests went unanswered, so the catalog does not treat the Capture ROM as open or freely licensed. Original cartridges remain worth searching for used.

Recreates the Senior PROM utility and protection-bypass board for compatible Apple IIe systems.

The assembled board was out of stock on 2026-07-24. The standard configuration is for an enhanced NTSC Apple IIe with 128K and two 5.25-inch drives. It does not fit a Platinum IIe; PAL and unenhanced versions require special arrangements with the vendor.
