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.
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:
Today on Facebook on the “Commodore Amiga” group I noticed a link to: https://console5.com/wiki/Converting_from_Surface_to_Leaded_Capacitors
And he who posted it asked about the opinions of using Holethrough caps.
And well again I was reminded of a horrible motherboard sent to me for a fix after a failed recap.
Well next card in my “060 Upgrade” walk-through is the Blizzard 2040.
This is the the board before doing any work on it. (I have added 32MB of RAM to be able to test it)
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:
A while ago I found a hack how to add 64MB or RAM into the Amiga 4000 motherboard:
To get there just check http://www.amibay.com/showthread.php?57613-64mb-fastram-to-your-A4000-mobo
ONE SIDENOTE: this hack will NOT work on Rev D Amiga 4000 (those with the 030 soldered onboard) or the A4000T
