A1200 FPU Upgrade (Onboard)

£16.66 Ex. VAT

A1200 FPU upgrade (onboard) which includes socket, FPU and installation.

What does the modification do?

This FPU modification adds a real FPU to the A1200 motherboard, there has always been a place (U0) for an onboard FPU but it was never added. This is a perfect compliment for a stock A1200 or one with an accelerator without an FPU option, for example The TF1230 or any standard ram upgrade like the 11Mb Fast Ram upgrade. However there are a couple of limitations of adding an onboard FPU.

  • The FPU will be using the CPU clock which is at 14Mhz, which means the FPU will be running at 14Mhz
  • The FPU will be disabled if you use a 040 or 060 accelerator, for example TF1260. This is because both the 040 and 060 processors do not acknowledge external FPUs as you can get those processors with built in FPUs.

This modification is available as an option on our A1200 recapping service, ReAmiga 1200 and Refurbished units.

  • Tested before any work has began.
  • All electrolytic capacitors removed using professional tools and techniques (no twisting off caps and boards a pre-warmed before the removing capacitors using hot air) this puts far less stress to the board itself.

  What is Ultrasonic cleaning? Ultrasonic cleaning is a process that uses ultrasound (usually from 20–40 kHz) to agitate a fluid, this fluid is made up for this specific job which is to clean and remove any flux left over from recapping.

amiga a1200 white case
Amiga A1200 White Case
Amiga A1200 white case new, manufactured by A1200.net What's included?
  • Top case including enhancements
  • Bottom case including enhancements
  • Enhanced bottom trapdoor with extra vents.
  • Enhanced rear trapdoor + extra plastic holder DVI / VGA shaped hole.
  • Rubber feet
  • Set of screws
How are these brand new?
In 2016 840 Amiga users made it possible in supporting a Kickstarter to reproduce the Amiga 12000 case, the new A1200 cases are made using Injection Molding manufacturing technique to produce top and bottom shells as well as trapdoors and parts. The process implies the use of 3 new moulds, the first one is for the top shell, second mould for the bottom shell and last one for trapdoors and parts, all produced using brand new moulds.
Enhancements galore:
The Amiga community has never died and some have produced some great add-ons over the years to make sure the Amiga is still relevant and useful today as it was back in the 80's/early 90s and these cases take full advantage of that weather that's simply transferring your existing motherboard from your existing Amiga 1200 or have a luxury of installing a MiST FPGA Board. Below are few more enhancements: [accordion] [pane title="External CF Adaptor" start=open] A CF slot can be opened up on the side of the A1200 case to allow easy access to what would be the CF card within the A1200 itself. [/pane] [pane title="MiST FPGA Board"] MiST is a FPGA based modern board that implements classic 16bit computers like the Commodore Amiga, Atari ST and 8bit systems like the Commodore 64, ZX-Spectrum, MSX, Atari XL/VCS, Apple II, Colecovision, Sega Master System, NES, SNES as well as Arcade machines. The primary difference between the MiST is that its NOT emulation. The new A1200 case has mounts to mount the MiST FPGA within the A1200 case. [/pane] [pane title="Raspberry PI"] Yes you can mount a Raspberry PI 2/3 within the new A1200 case with the use of the mounts already part of the case for a nice clean solution. [/pane] [pane title="Keyrah V2"] [caption id="attachment_18644" align="aligncenter" width="300"]Keyrah V2 Keyrah V3 for the Amiga 1200/600, C64, VIC 20 and C16[/caption] Keyrah V3 is an IO adaptor that allows you to use the original keyboards of the Commodore Amiga 600 and 1200, Commodore 64, VIC-20 and C-16 within their respective cases. The purpose of this you can then install a Raspberry PI which uses the original keyboard of that computer and providing 2 x D9 ports. The new Amiga 1200 case has mounts are located at middle top of bottom shell. This location make the keyboard adapter available for Raspberry Pi or MiST board. Original Amiga 1200 keyboard ribbon will fit nicely just at the right place on the keyboard adapter board. I/O connectors are accessible through rear panel I/O slots. [/pane] [/accordion]   So what are the differences between the original Commodore case and the New A1200 case?
  • The plastic is more resistant to UV alteration. To avoid the case to turn yellow over time.
  • All screws are secured with metal brass inserts. No more broken plastic clips.
  • The bottom trapdoor has extra vents for a better case air flow.
  • 2 new rear trapdoors are available to accommodate VGA and DVI. The third one is a Plain door.
  • The case supports the following modern devices : Raspberry Pi©, MiST© FPGA, Keyrah© V3 keyboard adapter, RapidRoad© Double USB and Lotharek© HxC Floppy emulator, Flashfloppy
