Macintosh SE/30 upgrades

Adds grayscale and external VGA display modes to the SE/30, with resolutions up to 1024x768.

For this system (exact model): Built for the SE/30 and tested with stock, IIsi-based, and third-party ROMs. The maker strongly recommends recapped and adjusted logic, analog, and power-supply boards, especially when stacking PDS cards.

Human review confirmed that the 30Video Greyscale Kit was out of stock on 2026-07-15. Check the direct product page for a restock.

Bidirectionally converts keyboards and mice between Apple's ADB interface and modern USB HID.

For this system (bus/interface): Connects to the SE/30's 4-pin mini-DIN ADB bus so a standard USB keyboard or mouse can be used with the Mac.

The BMOW store showed the Wombat as sold out on 2026-07-14. Check the direct product page for a restock.

Open hardware SCSI emulator that uses disk images on an SD card as replacement storage for vintage computers.

For this system (exact model): The official compatibility list names the SE/30. A machine using a third-party ROM SIMM may need a System file modification if it stops at the initial logo while booting.

Runs a 68030 CPU and 68882 FPU at 47 MHz for roughly twice the overall performance of a stock SE/30.

For this system (exact model): Designed for the Macintosh SE/30 and offered in PGA-socket and PDS variants. The maker reports compatibility with IIsi-based ROMs and custom ROM images.

Uses an SD card to emulate Apple floppy drives and, on supported systems, HD20 or SmartPort hard disks.

For this system (exact model): Macintosh floppy emulation is supported. HD20 hard disk mode on an SE/30 requires a Mac ROM-inator II replacement ROM.

The BMOW store showed this model as sold out on 2026-07-14. Check the direct product page for a restock.

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

For this system (exact model): Explicitly supports the SE/30 ROM SIMM socket. Some stock sockets have fit or reliability problems and may require the SIMM contact pads to be thickened with solder.

Replaces the stock ROM SIMM with a 32-bit-clean flash ROM, bootable ROM disk, and HD20 support.

For this system (exact model): Replaces the SE/30 ROM SIMM, enables native 32-bit addressing and HD20 support, and can allow up to 128 MB RAM. Some sockets need a fit shim.

The BMOW store showed the Carbon SIMM as sold out on 2026-07-14. It is incompatible with DayStar PowerCache and Turbo accelerators.

Actively converts classic Macintosh DB-15 video sync signals for use with compatible VGA displays.

For this system (bus/interface): Relevant only when the SE/30 has an expansion video card with a standard Macintosh DB-15 output; it does not convert the built-in monochrome display.

The BMOW store showed the Sync-inator as sold out on 2026-07-14. A monitor must still support the source resolution and scan rate.

Redesigns the SE/30 logic board as a buildable replacement with Gerbers, placement data, a BOM, and recreated programmable logic.

For this system (exact model): This is a complete SE/30 logic-board recreation rather than an expansion card. Low-power ATF16V8B devices do not work for the recreated PALs, and ATF16V8C devices may also be problematic.

Period 68040 accelerator originally made for a Macintosh IIci cache slot and usable in an SE/30 only through a specialized adapter.

For this system (exact model): A documented SE/30 installation uses Bolle's PDS-to-IIci adapter plus a patched INIT. The Carrera040 itself is a IIci cache-slot card, not a native SE/30 PDS card.

Use only a proven SE/30-to-IIci cache-slot adapter and the patched software. Never insert this card into a PDS slot or PDS pass-through: the connectors fit but are electrically different, and a wrong connection can destroy the accelerator.

Open hardware 10/100 Ethernet card designed around a modern controller for the Macintosh SE/30 PDS.

For this system (exact model): The SEthernet/30 hardware and driver were tested on an unmodified SE/30 under System 6.0.8, 7.1, and 7.5.5. The declaration ROM must be programmed before the system recognizes the card.
