Greaseweazle V4.1 USB Floppy Adapter Flux Reader Writer
Greaseweazle v4.1 allows versatile floppy drive control over USB. By extracting the raw flux transitions from a drive, any disk format can be captured and analysed.
This includes, PC, Amiga, Amstrad, PDP-11, musical instruments, industrial equipment, and more. The Greaseweazle also supports writing to floppy disks, from a range of image file formats including those commonly used for online preservation (ADF, IPF, DSK, IMG, HFE).

Amiga A500 / A500 Plus Keyboard Membrane (New)
Amiga A500 Keyboard Membrane brand new. If you have issues with your Amiga A500 keyboard with missing keys or missing rows of keys the chances are the membrane needs replacing. The A500 / A500 Plus was supplied with at least 3 different types of keyboard membrane – A version by Samsung had 2 keyboard connectors and these keyboard membranes are NOT compatible. There are also keyboards made by Cherry (with the C= key instead of the left Amiga key) and by NME (these have red Amiga keys) again this membrane is NOT compatible.
This membrane is compatible ONLY with models which have a single keyboard connector – the Mitsumi membranes (part numbers 56 A619A and 56 A619B) both with and without the extra blank / international keys (ie 94 and 96 key versions). If your unsure by all means contact us.
What if you have missing keys or rows of keys on the Keyboard? Try these possible fixes first:
- Check the keyboard plug is inserted all the way in the connector on the Amiga A500 / A500 Plus mainboard.
- If it’s only 1 or two keys the plunger may need a clean, strip down the keyboard and clean the plunger with some IPA.
- If it’s a whole row of keys missing its a very strong possibility that the membrane on your needs replacing.
Do let us know if any of the above fixes help you!

Keyrah V3 – Commodore Amiga, Atari ST, PC
Keyrah V3 allows you to connect original keyboards of classic computer systems like the Commodore 64 or the Amiga 1200 to modern computers (e.g. PC, Mac, or the Raspberry Pi) via USB. It also supports digital joysticks and analogue paddles of such classic systems, which will be converted to standard HID game controllers. Supported systems with this model are:
- Commodore C64 (all models)
- Commodore SX-64
- Commodore VIC-20 (VC20)
- Commodore C16
- Commodore C128D
- Amiga 1200
- Amiga 600
- Amiga 500
- Amiga 4000/CDTV
- Atari ST (8-pin connector only)
- PC XT / PC AT (with PS/2 adapter)
The following systems can be made compatible by mounting additional connectors on the circuit board or using adapters:
- Commodore C128
- Commodore C116
- Commodore plus/4
- Commodore PET (8296)
- Commodore CBM2 (B-Series)
- Amiga 2000/3000 (with PS2 adapter)
Keyrah V3’s switch allows you to switch between the standard and a keymap that’s geared towards emulation. This switch looks and feels like the original power switch of the Commodore 64, adding a third switch position that allows you to send an ACPI signal to shut down/power up your computer. To avoid triggering the shutdown procedure by accident, this third position is not locked, so the switch will always flip back from it if not held in place. For further safety, the ACPI signal is only sent to the computer after being held in this position for five seconds.
The box includes the Keyrah V3 circuit board and a printed manual. USB cable is not included. PCB colour will vary.

CA-PSU Amiga A500, A500 Plus, A600, A1200
CA-PSU Amiga A500, A500 Plus, A600, A1200 (CA-PSU stands for Compact Amiga Power Supply Unit), where “compact” designates the three target computers A500, A600 and A1200. It is the first power supply on the market that fully complies with the original Commodore specifications, introducing cable drop compensation for best regulation that even settles the voltage drop in the input filter of the target computers. This means that the voltage on the main 5V rail will never deviate more then 0.9%, measured inside the computer – no matter if the computer is in vanilla configuration or heavily expanded. Conventional power supplies will either supply too-high voltage to a vanilla machine, or too-low voltage to an expanded machine, causing malfunction or even defects. This cannot happen with our cable drop compensation technology.
Technical data in short:
- 5V, 5A, ripple/noise 50mV max. (typically 30mV)
- Overload on 5V tolerated up to 8A for 30 seconds
- 5V load regulation <0.6% typical, max. 0.9% under overload condition
- 12V up to 4A
- -12V, 0.1A
- Modern, high-efficiency DC-DC converter technology
- Total output power up to 60W
- Fanless, silent, extremely low heat
CA-PSU is a two-brick solution: One mains-connected power brick and the CA-PSU converter box with the switch and square 5-pin DIN connector to the computer. This moves the power switch a lot closer to the computer, reducing the probability of inadvertent switching, for example if the power supply is under the table near your feet.
CA-PSU has the best overall efficiency on the market, with a worst-case efficiency of 80.1% (best case >82.5%). The best competing product peaks at just over 70%, and some original Commodore power supplies have an efficiency of only 55%. This means that with our CA-PSU, there’s less total heat, less power consumption and a longer life expectancy because there is less stress on the components.
Naturally, CA-PSU features over-voltage protection – every modern power supply does. We wouldn’t consider it worth mentioning, but this protection is part of a more complex block to protect your valuable classic gear: There are two critical moments that need to be taken care of: Switching on and off. CA-PSU has a controlled 5V ramp-up when switching on, ensuring safe power-up of heavily-expanded machines. Traditional power supplies without such a controlled start-up ramp tend to “swing in” to the target voltage, which might cause malfunction or even defects. Further, switching off will start a short timer, ensuring that the next switch-on event can’t happen until a few seconds after switching off. This ensures that capacitors in the computer and expansion gear are sufficiently discharged, and switching on won’t cause 3.3V regulators of modern expansions to oscillate, which may cause severe damage.
In the unlikely event that these elaborate precautions fail, CA-PSU is covered by a German product liability insurance.
This new production run of CA-PSU includes an international power brick that directly plugs into the socket (no mains cable). International adapters included are:
- Central Europe
- United Kingdom
- Australia
- USA
CA-PSU is compatible with worldwide grid voltages and frequencies (110-240V AC and 50 or 60Hz).

ACE2b Amiga A500 A2000 2Mb Chipram Upgrade
ACE2b Amiga Chipram Extender 2MBytes. It is installed in the socket of the Fat Agnus chip of your OCS/ECS Amiga. It is compatible with these Amiga models:
- A500 up to board rev. 7
- A1500 and A2000, Rev. 4.1 and higher
- CDTV
- A2500 Rev. 4.1 and higher
The unit requires no soldering, but does require the removal of the existing AGNUS chip from the motherboard. The ACE2b then simply slots in to the existing AGNUS socket and the GARY adapter is socketed between the GARY socket and the GARY chip.
The ACE2b is jumpeless and does not rely on existing memory to be present so no ram is required in the trapdoor of the A500 as the ACE2b has the full 2Mb Chipram is located on the PCB itself, the chip ram on the main board of your Amiga will not be used any more.
ACE2b uses an ECS Agnus 8375 (included) that is switchable between PAL and NTSC video mode by software. It is compatible with Genlock interfaces. ACE2b starts up in NTSC mode. If you own an ACA500 or ACA500plus, you can fix the video mode to your preferred setting.
What’s included:
- ACE2b PCB with Gary Adaptor
- 8375 2Mb Agnus PLCC
We do offer an installation service, by all means contact us.
