Greaseweazle v4.1 Amiga Amstrad, Spectrum

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 - 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)

Greaseweazle V4.1 is the latest version, updated for mass production and with the following features:

Reads and writes 3", 3.5", 5.25", 8" disks (with suitable drive and cable)
Buffered outputs, for communicating with older 5.25" and 8" disk drives
Integrated power connector for directly powering most 3.5" disk drives
Write-enable jumper can be removed for safer preservation of precious vintage disks
Supports flippy-modded 5.25" drives
Supports Disk-Change detection as used by Rob Smith's integration into the WinUAE Amiga emulator
3 user-definable outputs (eg. 8" interface REDWC signal)
100% factory tested, and tested again by me before shipping

More information and documentation on the wiki page here:

This listing is for the Greaseweazle V4.1 device only. And does not include which you will require:

A disk drive (for example a PC 3.5" or 5.25" drive)
A floppy ribbon cable (typically you want a standard PC cable with 'twist' on pins 10-16, to communicate with a PC floppy drive)
Floppy drive power cable, or power supply

Built by Zero Flux Development. And yes this is the item mentioned on Tom's Hardware: https://www.tomshardware.com/news/raspberry-pi-emulates-amiga-1200-uses-real-floppy-disks

68040 running at 25Mhz (our cards are set up for 68060 CPUs ONLY)
68060 running at 50/75/100MHz (CPU heatsink and fan high recommended with a REV 6 CPU) LC/EC variants 50Mhz is suggested.
128 MB of DMA Fast RAM.
Temperature and voltage monitoring via I²C.
Overclocking capability up to 100 MHz with full 68060 Rev. 6 CPUs ONLY with heatsink and fan (we don't offer support for overclocking or damage).
Onboard 5V header to connect the optional CPU fan.

*A3000T is very picky and has not been tested, so if being used with an A3000T the card is sold as seen. Installation guide here [hr] For every BFG9060 sold we donate a percentage of the sale to Matthias Heinrichs to support further developments and we also support our builders. *A3000T is very picky and has not been tested, so if being used with an A3000T the card is sold as seen.

Keyrah V3 for Commodore Amiga, Atari ST & PC

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.

BigRamPlus 256Mb for Amiga A3000 A3000T A4000 & A4000T

BigRamPlus is a 256 MByte memory expansion for any Amiga with Zorro-III slots, i.e. Amiga 3000, Amiga 3000T, Amiga 4000 and Amiga 4000T. BigRamPlus is only guaranteed to work with the original daughter boards of these computers. It may or may not work properly with third party bus boards made by Micronik, RBM, Eagle, Elbox, etc. Memory is used by all operating systems up to OS3.9 automatically. Linux/BSD may need special patches to use this memory. AmigaOS 4.0 does not permit the use of a Z3 memory card, the computer won't even boot into the OS. AmigaOS 4.1 can use the card's memory as swap memory. Starting with OS4.1FE, update#1, this memory can be used as main memory. Box contents:

BigRamPlus card
Instruction sheet

You will need in addition to that:

A computer with Z3 slots (Z2 will not work!)
A screwdriver to open your computer

X-Surf 100 Network card for Commodore Amiga

X-Surf 100 for all Commodore Amigas with Zorro Slots

X-Surf 100 is a networking card for all Amiga computers with Zorro slots. For the Amiga A2000 or Zorro-daughterboards for the A1200, it will run at Z2 speed. If installed in an Amiga A3000, A4000 or the respective tower versions, it will run at Z3 speeds, which is up to five times faster than Z2. Key features:

100MBit physical link rate
Sana-II device for use with OS2.0 up to OS3.9
Officially supported in the Linux-m68k kernel
Space- and power-saving design
Gold plated Zorro contacts and stainless steel metal bracket
Local expansion port for our high-speed USB module "RapidRoad"

Drivers can be downloaded from here. Manual here Wiki here Requirements:

TCP/IP stack such as Miami DX, AmiTCP, Genesis (included in OS3.9) or Roadshow
Sufficient RAM and 68020 CPU or higher
Kickstart/Workbench 2.0 or higher
File transfer method for drivers to be transferred to the Amiga

Transfer rates of over 1600kBytes/s have been measured with the X-Surf-100. Please note that the classic Amiga architecture and the current TCP/IP stacks for the Amiga don't allow saturating a 100MBit Ethernet link. Performance in your system may be slower due to CPU performance and programs running in multitasking. Please note that we cannot guarantee the X-Surf-100 to work in third-party Zorro boards as used in tower conversions, such as boards made by Eagle, Mikronik, RBM or Elbox. The X-Surf-100 may or may not work in these boards. Although the bus interface is designed to tolerate many mistakes that the vendors of those third-party boards have made, we can only guarantee proper operation in original Commodore daughter boards. Should the card fail to work in such a third-party board, you may have to close the Z2 jumper and downgrade to Z2 speed. For operation in Z3 computers, the Buster-11 chip is recommended. If there is only one DMA master in the Z3 system, a Buster-9 may also be used. Owners of the Merlin graphics card must have the latest hardware patches installed. Owners of the Mediator PCI/Zorro daughterboard must close the "swap" jumper. The X-Surf-100 is officially supported in the Linux-m68k kernel.
