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.

Buddha Plus One IDE Controller
Buddha Plus One IDE Controller Commodore Amiga
Buddha Plus One IDE Controller for Commodore Amiga with zorro slots (2023 version) is a IDE controller for Amiga computers with Zorro slots (Amiga A2000, A3000, A4000 CheckMate 1500 Plus with Zorro interface) and provides you connectivity for hard drives,CD-Rom Drives, DVD Drives (both readers and writers), and of course CF cards and SSD with PATA interfaces.. Buddha Plus One features:
  • Two IDE ports
  • One CF card slot
  • 1Mb of Fast Ram
  • GUI-based settings tool
  • Elaborate LED concept
  • High Speed
  • Multiple measures to prevent wrong installations
The two IDE ports and the CF card slot are non-conflicting. This means that you can use up to five mass-storage devices at the same time, and if that's not enough, you can add more Buddha controllers to the same computer! Added memory While the combination of a mass-storage controller and memory on the same card is not a new invention, the 1MByte of true 0-wait state fast memory of the Buddha Plus One controller does not conflict with existing memory cards. If you are expanding a system that has already maxed out it's 8MByte of Z2 space (no matter if it's fastmem, a PC bridge card or RTG graphics), Buddha Plus One will still add 1MByte of memory, without using any of the precious Z2 expansion space. A2000 users can choose to map the memory to one out of two addresses: The legacy "trapdoor memory" address $c0.0000, where it adds compatibility with old software titles (especially for machines that have been expanded to 1MByte or 2MBytes of chip ram), or to the normally-unused address space at $a0.0000. A3000 and A4000 users can only use address $a0.0000. Memory is not available if installed in a Zorro expansion of an A1200. Robust against installation errors Buddha Plus One has a long heritage and we've learned from numerous support cases of the past decades that in the heat of the moment, you may accidentally plug in the card the wrong way round. For the first time in Amiga history, we're presenting mechanical and electrical measures to either prevent wrong installation, or to keep the controller safe from harm if you manage to plug in the card the wrong way round. Just flip the card around and it'll work as if nothing bad ever happened. Easy configuration While previous versions of the Buddha controller could only be controlled with command line tools, Buddha Plus One introduces a GUI that is provided in the ROM of the controller, so no software installation and/or download is required. This GUI will even work with Kickstart V1.3! Elaborate LED concept

The original Amiga computers only have a single HD LED. Buddha Plus One will unite all access-LEDs (including onboard IDE/SCSI accesses) into a single one without soldering or complicated configuration steps. Two LED cables are included with Buddha Plus One, making LED wiring easy without soldering, and without the need to drill holes for additional LEDs into precious original cases. The LED output will automatically sense how many LEDs there are in a row (one in case of A2000/A4000 or two in case of the A3000), and the LED input of Buddha Plus One will accept any polarity.

Quick boot support

The Amiga can start blazingly fast. Amiga users are so used to having a usable desktop within seconds after switching on that every single additional second is already a reason to be worried. Buddha Plus One gives the user various options to skip unnecessary wait times: The maximum time that Buddha will wait for a drive to spin up can be set in the graphical startup menu. Unused ports can be switched off, and if you have an onboard IDE/SCSI controller that you're not using any more, it can also be switched off in the Buddha Plus One configuration, saving several ten seconds of boot time.

Improved speed

Let's face it: Buddha has never been a speed demon. The Z2 bus with it's 7MHz and 16 bits has it's limits, and that's in the neighbourhood of 2.3MBytes/second, measured with a medium-speed 68020 or 68030 CPU. However, there's two special cases where Buddha Plus One adds significant transfer speed: First, an un-accelerated A2000 would struggle to reach 800KBytes/s with a 7MHz 68000 CPU on previous versions of the Buddha controller. Buddha Plus One now adds hardware acceleration that improves transfer rates with 68000 CPUs by about 35%. Buddha Plus One with a 7MHz CPU beats the "magical" 1MByte/second barrier by a large margin. The second special configuration where Buddha Plus One can add speed is in the Z4 board for an A1200 computer. Z4 boards are also known as "Elbox Z4" or "Winner Z4" Boards, and they sport a "Fast-Z2" mode that can add up to 50% to measurable transfer speed. We recommend to only activate this mode if only CF cards or DOMs are used. Stability with long IDE cables may not be given.

Extended software installation

Buddha Plus One comes with a DOM (disk-on-module) pre-installed. This DOM contains our automatic partition/install tool and licensed copies of Amiga OS 1.3, 2.1 and 3.1. Partitioning and installing a CF card or hard drive has never been easier! Even if you have lost your OS installation floppies or your floppy drive is defective, you can bring your Amiga to life within minutes. If a CD ROM drive is found, drivers and file system are also automatically installed, letting you install more software or Amiga OS V3.2 from CD (Amiga OS3.2 is available separately in this shop). If there is any version of the X-Surf networking card in your computer, you can continue to install a TCP/IP stack and network GUI. This will break the vicious circle of having to transfer software to the Amiga in order to install a transfer method for software.

What's included:

  • Buddha Plus One
  • LED extension 24cm
  • LED connection cable 24cm
  • Instruction manual (English/German)

BigRamPlus 256Mb Commodore Amiga
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.
