Archive For: A1200


Lately I have been seeing many Amiga 600 and Amiga 1200 with bad Band Pass Filter (Z221) and Delay Line (Z222). This generally causing bad picture quality on composite and the RF-modulator. There are many suggested solutions out there but none that really replaces the Z221 and Z222, until now. While attending to Datastorm 2018 ... Read More

ApolloVR Files

The Apollo 1260 Voltage Regulator is needed when an upgrade is made on a Apollo 1240 from 68040 to 68060 CPU. This is because the 68060 used VCC 3.3V instead of VCC 5V. I based the design around the LM1085 voltage regulator that I find to be very good, but size is a bit bigger ... Read More

BPPC Heatsink Files

Over the past months I have been asked several times regarding the Blizzard PPC Heatsink I made. I have decided to release the files, but they have to be modified, else the heatsink will not fit in the A1200 desktop case. The modification that needs to be done is simply remove the following cooling stubs. ... Read More

INT7 Files

I have decided to share all my own creations for Amiga and a first step is to release the INT7 (Level 7) PLCC adapter for Amiga 600/1200/4000D(T). This is perfect when using for example a custom Amiga Kickstart ROM with HRTMon in it, or when using for example AsmOne/Pro with INT7 interrupt enabled. Personally I ... Read More

Z221 / Z222 Fix

Please note that this is obsolete! Please check the following replacement instead: CXA2075 For those who repair and/or change electrolytic capacitors on Amigas has probably sometime bumped into bad Z221 and Z222 which is the band pass filter and delay line. These components are cruical for the RF and Composite video output. When they are ... Read More

A1200 CN1A Cable

So I have been absent for quite a while now, but I promise that it has been for a good reason. Been busy with work, Amiga development (both hardware and coding) and all other things you not sitting at a computer. Recently I have done a few re-caps and Repair of spare A1200 boards and ... Read More

INT7 Adapter

A new year and possibly many new projects that will be done and also new ideas that will take place. Last year was rather hysteric and this blog one one of many things that I had to put on my “to-do-list” (sadly). Anyway, I atill managed to finish many projects and only a few of ... Read More

SFX Power

My project with Blizzard PPC and BVision moves forward and the next challange was to get more power to the Amiga 1200. A normal Amiga 1200 with average expansions will be good with 3.5A standard PSU but when it is expanded with both the above cards, it is recommended to have 8-10A. Many examples that ... Read More

BVision Pimping

So, the Phase5 Blizzard Vision (BVision) card had some minor fixes on itself that I wanted to fix before I added it into my project. The first one was a 5V+ power injection mod that is needed and the second was a quick fix on a damaged leg with kynar wire and polyimide tejp as ... Read More

New Heatsink

So it has finally arrived… A few weeks ago, or even months I posted a blog with a new design on a heatsink to be used with the Phase5 Blizzard PPC. It was not easy to find someone with CNC experience that could do the job for me but shame on you if you give ... Read More

A1200 Cap Map

Ahh… What the heck! Since I could not find any good reference for the location of all the capacitors in a Amiga 1200 I decided to make my own. The result can be found below and I have also made a high resolution version of it that  can be seen as a text URL below ... Read More

A1200 PWR

The X-Mas has just ended and I have some days off from work so why not continue with some of my projects. To be able to feed my BPPC and BVision with extra juice I decided not to go with the “Floppy-Feed-Solution” and instead use a SFX PSU in my Amiga PSU and then connect ... Read More
