Amstrad CPC 6128 Plus upgrades

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 includes the CPC 6128 Plus. Confirm motherboard clearance, CPU package, and orientation before removing or socketing the processor.

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.

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 (stated family): The current official HxC page names the CPC 6128 Plus. Confirm the exact internal connector, adapter, drive select, power pinout, mounting, and firmware before installation.

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 (stated family): The current official HxC page names the CPC 6128 Plus. Confirm connector type, adapter, drive select, power pinout, mounting, and access to media and controls.

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 (stated family): The current official HxC page names the CPC 6128 Plus. Confirm connector adaptation, power pinout, drive select, mounting, and the safe USB-first disconnect sequence.

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.
