Introducing the Re-Amiga 1200

tl;dr:    Files at bottom of this post :)


One slow day (12th of june 2018) being on a hotel doing work for one week I asked on facebook on the “Commodore Amiga” group:

 ”Reversetime. What pcb do you think I should reverse? Come with ideas. A board often damaged by battery or caps. Preferbly smaller ones. So give me hints of.. “whats next”

Doing the A3660 CPU board, the first open “Seminative” 060 solution. and why.

This is the story how to reverseengineer a 040 board, and take it to the next step.

This board is shown for the first time at Amiga32 in Neuss/Germany

TL;DR:  files at bottom of this post!


The Commodore A3640 is a well known CPU board for the Commodore Amiga.

It is also know as the 040 board that is ordered as the WORST CPU board ever…

AND  it is true..

BUT! this board is the only we have with all data on all chips..  all GAL data is released by Dave Haynie some time ago.

Upgrading the Apollo 1240 to 1260

Well next card in the series how to upgrade different 68040 cards to 68060, it is time for the Apollo 1240.

First, As Jens schönfeld ( Individual Computers ) owns the rights of the Apollo cards, I asked him for permissions especially when this requires a ROM change.  he told me that I was allowed however only if I publish a diff..

But he also pointed out that he does not like the Apollo. This is no news but this is what he told me:

Upgrading the Phase 5 Cyberstorm MK2 from 68040 to 68060

This is how to upgrade a Cyberstorm 68040 Accelerator for the Amiga 3000/4000 to 68060.

I got a A4000 motherboard and Cyberstorm MK2 040 sent to me from my friend Klementino from Croatia to be repaired and maybe do something with the Cyberstorm, so why not max it out?

The Cyberstorm Acceleratorcars are the best accelerators for big box Amigas and it for sure is a beaty:
