Amstrad CPC 6128 upgrades

FPGA-based AY-3-8912 replacement with the original Amstrad sound path and an optional separate three-channel stereo output.

For this system (exact model): The sellers supply a CPC 6128 installation diagram and describe the AY-3-8912 module as a no-solder socket replacement that automatically selects Amstrad mode. Optional separate stereo output requires an invasive resistor-removal and wiring modification.

The Lotharek page exposed a login-or-register-to-buy path, and Retro Lemon showed the module in stock on 2026-07-28. Retro Lemon identifies it as an AY-3-8912 replacement that auto-detects Amstrad or ZX operation and says normal installation is a no-solder socket swap. Optional CPC 6128 stereo output still requires removing or cutting resistors R117 through R120 and wiring AL and AR or a separate jack. Exact ZX models, other chip footprints, orientation, voltage, clock, and firmware remain undocumented, so no ZX target is attached.

Adds 512 KB of SRAM to an Amstrad CPC 6128 or CPC 6128 Plus through the Z80 CPU footprint.

For this system (exact model): The seller explicitly names the CPC 6128. The module occupies the Z80 footprint and carries the original CPU above it, so a soldered CPU must first be safely removed and socketed.

The Lotharek page exposed a login-or-register-to-buy path on 2026-07-27. The CPU must be removed or desoldered, the module fitted in its place, and the CPU installed on the module. Confirm pin-1 orientation, socket quality, board clearance, and the computer's condition before beginning the invasive installation.

Converts the CPC 6128's internal 26-pin floppy connection to a standard 34-pin Shugart interface.

For this system (exact model): The seller explicitly names the CPC 6128 and describes its 26-pin internal connection. Installation replaces the original flat cable by soldering; verify connector orientation, drive configuration, power, and physical fit before use.

The Lotharek page exposed a login-or-register-to-buy path on 2026-07-27. Installation requires soldering the adapter in place of the original flat cable. A replacement drive or HxC emulator is not included, and the attached device still needs the correct configuration, power, mounting, and media setup.

Replaces the CPC 6128's six-pin video socket with a Mini-DIN 9 output wired to the Mega Drive 2 A/V standard.

For this system (exact model): The seller's installation instructions are specifically for the CPC 6128. This is an invasive connector replacement, not an external plug-in adapter; use the documented 5 V and audio wiring and do not remove the resistors identified by the seller.

Both the adapter-only and SCART-bundle pages exposed login-or-register-to-buy paths on 2026-07-27. Installation requires desoldering the original six-pin socket, soldering the adapter, connecting its 5 V wire, and wiring the AL and AR audio pads. The seller explicitly says not to remove the nearby resistors. Confirm pin orientation and display compatibility before applying power.

Maps an independent second gamepad button to Up while preserving the controller's normal directional Up input.

For this system (stated family): MicroMiga tags the adapter for the Amstrad CPC family. Confirm controller wiring and choose the connector version that fits the exact machine.

MicroMiga listed the family from EUR 8.99 on 2026-07-30. The extracted variation table explicitly marked the short FAT version out of stock but did not expose a reliable stock state for the longer, slim machine-side version, so confirm the desired model before ordering. A controller needs genuinely independent fire buttons; duplicated or cloned fire buttons do not work for the remapping.

Replaces compatible 34-pin floppy drives with read/write disk images on SD or SDHC media.

For this system (exact model): The HxC manual gives exact CPC 6128 jumper and first-drive instructions. The computer needs a correct 26-pin-to-34-pin adapter and mounting solution. Its floppy power connector exchanges the usual 5 V and 12 V positions, so follow the documented wiring rather than plugging in a standard lead.

All fourteen Rev C, Rev F, and MAX hardware variants exposed current login-or-register-to-buy paths on 2026-07-27. Rev C and Rev F use a standard floppy 5 V supply; the manual specifies at least 400 mA and says the 12 V line is unused. MAX accepts either 5 V over Micro-USB or 7-12 V center-positive DC power. Verify pin 1, drive-select jumpers, cable twists, voltage, and physical fit before connection: some computers reverse the usual 5 V and 12 V floppy-power positions, and incorrect power can damage both emulator and host. The firmware reads and writes supported images but does not reproduce variable-bit-rate protection completely; IPF and STX support is partial.

Adds read/write SD floppy emulation in compact 34-pin and 26-pin FPC forms.

For this system (exact model): Lotharek lists the CPC among tested hosts and the HxC documentation gives exact CPC 6128 setup. Do not assume the Slim 26-pin FPC connector matches the CPC cable: use a documented adapter and verify its pinout. The CPC 6128 exchanges the usual 5 V and 12 V floppy-power positions.

All five Lotharek Slim variants exposed current login-or-register-to-buy paths on 2026-07-27. Choose the 34-pin HE10 or 1 mm 26-pin FPC version for the host; the 26-pin form requires the manual's ID0A setting. Supply regulated 5 V and verify the host connector, voltage, pin 1, drive select, cable, and mounting before connection. The manual specifies at least 300 mA and a 500 mA maximum figure. The firmware reads and writes supported images but does not reproduce variable-bit-rate protection completely; IPF and STX support is partial.

Streams read-only floppy images from a modern USB host to compatible 34-pin drives or an Amiga external-floppy adapter.

For this system (exact model): The USB HxC documentation names the CPC 6128. Use a correct 26-pin-to-34-pin adapter, observe the CPC's nonstandard power wiring, configure drive select, and disconnect USB before changing the floppy-side cable.

The standalone unit, cable set, and Ami2PC bundle exposed current login-or-register-to-buy paths on 2026-07-27. The official HxC home page and release notes show that the software project remains active in 2026. The unit needs a modern computer running the HxC host software and emulates disks read-only. The standalone set includes a 40 cm floppy ribbon and USB A-to-B cable; Ami2PC instead adds the Amiga external-floppy adapter. Never connect or disconnect the 34-pin or Amiga-side cable while USB is attached; disconnect USB first. Ami2PC can use Amiga disk-copy software to write a real disk in DF0 from an emulated DF1. Its early-boot workflow needs Kickstart 2.0 or newer. The seller still does not identify which oldest Amigas need its unspecified modification, so do not rely on early-model boot support without separate instructions.

Adds about 1.7 meters of reach between a compatible nine-pin controller and its vintage computer.

For this system (stated family): AutumnHippo lists the Amstrad CPC family. Extend only a controller already verified for the CPC.

AutumnHippo exposed an add-to-cart route at USD 7 on 2026-07-30. Protovision separately showed ten joystick extension cables in stock at EUR 10 with a one- to two-week shipping estimate. The exact long and short products pictured by the C64 OS guide are not identified, so the catalog keeps current length and seller variants together.

Provides a new 1.7-meter nine-conductor lead for repairing compatible vintage joysticks and controllers.

For this system (stated family): The seller lists Amstrad CPC controllers. Reproduce and verify the controller's original wiring before connecting it to the CPC.

AutumnHippo exposed an add-to-cart route at USD 7 on 2026-07-30. Basic soldering is required. Trace the existing cable or controller circuit before removal: the seller explicitly warns that wire colors can differ and that systems sharing a nine-pin plug do not necessarily share controller wiring.
