| AvailableChecked Jul 27, 2026 | A500 8 MB IDE2by Oleg Mishin / Lotharek | Adds 8 MB of Fast RAM and a bootable 44-pin IDE controller at the Amiga 500 CPU socket. The assembled Lotharek revision exposed a login-or-register-to-buy path on 2026-07-27; the original Oleg Mishin design files, ROM, firmware, software, and four-layer PCB are public. The box contains only the board. Kickstart and Workbench 1.3 or newer can autoboot without a patched scsi.device. A socketed CPU makes installation simple, but an unsocketed CPU must be desoldered. Pin 1 must be observed when attaching CF or SD hardware because a reversed adapter can destroy the CPLD. The open repository documents the original A500 design, while the current seller alone claims A500 Plus support for its revised hardware. |

| Sold outChecked Jul 24, 2026 | Apple IIgs 8MB RAM/ROMby A2Heaven | Combines 8 MB of fast static RAM with an optional 512K boot ROM and built-in IIgs debugging software. The card was out of stock on 2026-07-24. The optional ROM portion makes the assembly wider than a plain memory card; check clearance around long slot cards, especially in slot 7. |

| Build itChecked Jul 24, 2026 | GR8RAMby Garrett's Workshop | 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. |

| AvailableChecked Jul 27, 2026 | Lotharek SRAM Replacement Familyby Lotharek | Replaces Atari 8-bit dynamic RAM with modern SRAM or configurable FPGA-managed PSRAM in three current versions. All three memory variants exposed login-or-register-to-buy paths on 2026-07-27. Installation goes under the CPU and may require removal or isolation of the original DRAM, desoldering, new sockets, and EXT_SEL or CAS_INHIBIT connections. The Professional version also uses an MMU adapter and its page says to install the latest firmware before use. The optional Freddy Module v2 cannot operate alone: the seller requires the basic SRAM module first and says VBXE owners do not need the Freddy replacement. |

| Sold outChecked Jul 24, 2026 | Macintosh Portable 8 MB Memory Upgradeby Techknight and MacEffects | Adds bank-activity LEDs and up to 8 MB of recognized memory through the Macintosh Portable memory slot. The MacEffects page said Sold out on 2026-07-24. The non-backlit M5120 is supported at 8 MB; a reported 9 MB jumper setup is unstable and unsupported. The backlit M5126 is sold as a 5 MB card unless the installer adds the included /AS jumper wire at their own risk. |

| Sold outChecked Jul 24, 2026 | PiggyBack8Mby A2Heaven | Adds 8 MB of low-power SRAM and battery-backed storage to a RamWorks III card. The card is currently listed as out of stock. It is an add-on and requires a compatible RamWorks III base card. |

| Build itChecked Jul 24, 2026 | RAM2E IIby Garrett's Workshop | Adds low-profile, adjustable RAMWorks-compatible auxiliary memory to an Apple IIe. The assembled Tindie card was out of stock on 2026-07-24 and had been sold out since December 1, 2025. The open repository remains buildable. A Revision A IIe needs the card's DHGR jumper resistor or trace removed and then loses double-high-resolution graphics support. An A2Heaven VGA Scaler's long 14 MHz clock lead can cause RAM errors unless its clock connection is buffered or otherwise corrected as documented. |

| Build itChecked Jul 24, 2026 | RAM2GS IIby Garrett's Workshop | Adds selectable 4 MB or 8 MB of low-profile SDRAM fast memory to an Apple IIgs. The assembled Tindie card was out of stock on 2026-07-24 and had been sold out since June 17, 2025. The repository retains hardware, programmable-logic, documentation, and fabrication sources. Select 4 MB when every byte must be DMA-accessible; at 8 MB, only the first 4 MB is DMA-compatible. |

| AvailableChecked Jul 24, 2026 | RamFactor1M and RamFactor8Mby A2Heaven | 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. |

| Sold outChecked Jul 24, 2026 | RAMGS/4 and RAMGS/8 Memory Expansionby GGLABS | Adds either 4 MB or 8 MB of low-power fast RAM to an Apple IIgs. The GGLABS Tindie store was taking a break on 2026-07-24, so neither capacity had a current order path. Choose one capacity; both occupy the dedicated memory slot. |

| Sold outChecked Jul 24, 2026 | RamWorks8Mby A2Heaven | Adds 8 MB of auxiliary-slot SRAM and battery-backed storage to an Apple IIe. The assembled card was out of stock on 2026-07-24. It is a complete auxiliary-slot card, not the PiggyBack8M add-on for a separate RamWorks III. |
