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 time I will show how to upgrade the Blizzard PPC from 68040 to 68060. (I have NO equipment for BGA soldering so no PPC upgrade)
So, We take this BPPC Card:
This card is equipped with a SCSI controller aswell. But you do the same thing on both cards.
In my Series of upgrading to 060 cpu. It is time for the Blizzard 1240.
I got this to have in my “Demo-party” Amiga.
One Blizzard 1240. .(YES it has the 1260 print on the back. all 040 have that)
A friend of mine wanted to upgrade his WarpEngine 3040.
As he now uses it in his A4000 instead of 3000 he wanted possability of 128MB RAM and a faster CPU.
So. First lets inspect the card
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
I was sent an Amiga 2000. The powersupply on it died.
So how to fix this? well. you can put in an modern ATX Powersupply. So I did, and this is a short writeup of how to do it.
First of all, as most (all?) modern ATX PSUs do not contain the -5V signal, you will have problems using some ISA cards if you use a bridgeboard. but as this is not a very common usage, this will not be a big problem.
So, first, remove your old PSU and open it.
IMPORTANT! do NOT touch the big capacitors on the A2000 PSU or the ATX one.
One of the most common problem with the Amiga 4000 is for sure Battery leakage.
This post will be about repairing such stuff and will be updated.
