DiscontinuedChecked Jul 27, 2026Angry Space Invader Dual Joyby Lotharek

Adds two configurable joystick ports, reset control, activity indicators, and an expansion pass-through to ZX Spectrum hardware.

Lotharek marks the interface discontinued and explicitly says it does not work on the Timex 2048. A used unit can contain first-release or later firmware with different mode choices and address decoding, so identify the firmware and test pass-through hardware before relying on it.

AvailableChecked Jul 27, 2026BISON FPGA DivMMC TurboSound 2xAYby Lotharek

Combines DivMMC-compatible microSD storage, 512 KB of expansion RAM, dual-AY audio, DAC modes, and configurable joystick or mouse input on the ZX expansion bus.

The seller exposed a login-or-register-to-buy path on 2026-07-27 and documented firmware 1.5. Power off before changing the edge connection or input mode. Automatic Sinclair-versus-Amstrad selection depends on 9 V at edge pin 3B; compatible clones without that signal need the documented modification. Firmware updates require a separate Gowin programmer and removal of the flash ROM. Prepare a separate FAT32 microSD card with the supported ESXDOS release.

Sold outChecked Jul 27, 2026C64U User Port Adapterby Commodore

Brings the Commodore 64 Ultimate's internal user-port header to an edge connector for user-port peripherals.

The direct Commodore listing was out of stock on 2026-07-27. The connecting cable is included. The seller documents this only for the Commodore 64 Ultimate, whose user-port header is internal; an original C64 already has an external user-port edge connector and does not need this adapter.

AvailableChecked Jul 27, 2026DIAGNOROMby Lotharek

An external fifteen-ROM selector for original Sinclair 48K, 128K, and grey +2 computers, controlled by one button and binary indicator LEDs.

The seller exposed a login-or-register-to-buy path on 2026-07-27 and explicitly limits support to original Sinclair 48K, 128K, and grey +2 machines. Power off before connecting or removing it. Confirm the exact ROM contents and any software licensing from the current unit rather than assuming every example named on the board is supplied or redistributable.

DiscontinuedChecked Jul 27, 2026DivIDE Revisedby Lotharek / Velesoft

Adds CompactFlash storage, selectable disk firmware, an LCD, and a five-mode joystick interface to original ZX Spectrum computers.

Lotharek marks this revision discontinued. The seller says its joystick functions were tested on original Sinclair and Amstrad ZX Spectrum computers and does not guarantee clones. Media needs one active FAT16 partition, and compatibility still depends on selected firmware and correctly prepared software images. Identify the installed firmware and switch settings before using a second-hand unit.

AvailableChecked Jul 27, 2026DivIDE_AYby Lotharek

Combines CompactFlash storage, four selectable firmware slots, AY sound, stereo output, and two joystick ports on a ZX Spectrum expansion interface.

The seller exposed a login-or-register-to-buy path on 2026-07-27. Use a CompactFlash card with one active FAT16 partition and remove it only while power is off. The page distinguishes Sinclair and Amstrad bus modes, says the grey +2 is not an Amstrad-mode machine, and explicitly names +2B and +3 for Amstrad mode. It does not clearly establish +2A support, so that model is not attached.

AvailableChecked Jul 27, 2026DivMMC-USBby Lotharek

Combines DivMMC microSD storage, USB HID input, four ROM slots, snapshot storage, dual-AY audio, and DAC modes in one ZX expansion interface.

The seller exposed a login-or-register-to-buy path on 2026-07-27. Its published testing covers the original 48K, original 128K, Pentagon, and KRAKEN. The page says +2A and +2B compatibility still has known issues and that keyboard-mapped USB input will not work on +2A or +3 because of data-bus coupling; those models are not attached. Treat the described resistor workaround as experimental, not an installation recommendation. Follow the separate FPGA and USB-controller update procedures exactly.

AvailableChecked Jul 28, 2026KempAY CPLDby Lotharek

Adds AY sound, stereo output, joystick and mouse modes, reset controls, and edge-connector pass-through to ZX Spectrum-compatible expansion buses.

The seller exposed a login-or-register-to-buy path on 2026-07-27. The page describes ZX Spectrum and compatible expansion-port use but does not give an exact computer, power, or later-Amstrad compatibility matrix. Human review supplied no readable model-specific evidence, so the record remains only on the shared expansion-bus page. Confirm the intended machine and power off before changing the edge connection or input hardware.

AvailableChecked Jul 28, 2026Kempston MAX 2by Lotharek

Adds two configurable Atari-style joystick or mouse ports and a pass-through connector to broadly compatible ZX Spectrum expansion buses.

The seller exposed a login-or-register-to-buy path on 2026-07-27 and spells the listing name Kemspton MAX 2. Power the computer off before connecting or removing the interface, joysticks, or mouse. Original Sinclair joysticks are not supported. Human review supplied no readable exact-model matrix, so the record remains only on the shared expansion-bus page; confirm power rails and later Amstrad-model behavior before purchase.

Sold outChecked Jul 30, 2026Ultimate64 User Port Adapter v2.0by 1541 Ultimate

Brings an Ultimate64 replacement board's internal user-port header to a C64-style edge connector with the power rails needed by compatible peripherals.

The 1541 Ultimate store listed version 2.0 for EUR 9.98 but out of stock on 2026-07-30. The flat cable is included. The official documentation warns that the connector has only one correct orientation: its red wire must align with pin 1, and a shifted or reversed connection can damage the board or accessory. The header's extra pins can drive either 9 VAC generation or an APA102C LED strip; the documentation says 9 VAC is enabled when LED-strip use is off. Do not assume this earlier Ultimate64 adapter is interchangeable with Commodore's separate C64U User Port Adapter.
