The AmigaOne X5000 Bootscreen, could possibly make the source files available so people can see how it was created. Also could post other designs that got scrapped in favour of this one :)

Graeme Cowie has been working very hard on Rygar for the Amiga Platform.

Stephen (Steve/Steven) Crow is most likely a name some of you have heard a few times in the past and this is for a reason, his games had a certain style and some say they even had magic in them and even more think of his games as if they are the best of its […]

I saw something very special a few days ago, no it wasn’t Santa but it was almost as good as that, it was a post from Daniel Lakey that announced the release of a brand new game for the Amiga. What was so special about this was that he made this game for his son […]

ok this part is more about the extras etc.

First we have some weird A1200 “extras”.   as you might have noticed I missed one transistor and one diode at the parallelport:

Looking at schematics

Ok.

Now when we have a minimal setup.  Lets fix an issue that will make the machine unstable. especially when no monitor attaced:

Add a 74HCT244 at U32:

Lets do some tests.  first a CIA test:

So lets add memory.  This is also a quite tricky part of the ReAmiga project as the distance between the chips is making it harder to handsolder.

This is how I am doing it:
First I tin all pads:

Add flux ontop of it and put a memorychip on U18 (thats the location of the top).

Time to get some code running on this.

Time to get this board to a state that I call “minimum startup”  it means this is the minimum population of components needed to get Diagrom to start.

First add the Keyboard MPU:

I decided to rewrite my post about how to build an ReAmiga from scratch.  It simply was too much work to do it resistor by resistor..

So first, I decided what board to use. And well  Black is nice. so that I will use here aswell:

This is the Errata post of the ReAmiga project.

DO Check this post if you are doing soldering of ANY revision of the ReAmiga. as this page might change if stuff is found etc.

it works like this:  in the title I write what I fond as issues.  so if you have a Rev 1.0 board. you need to read the 1.0 header.  do those fixes. AND also add fixes for 1.1, 1.2 etc..  (unless mentioned in the text)

ReAmiga Rev 1.0 TESTVERSION (note this is the TESTVERSION it have this also printed on the PCB! to NOT mix with the released Rev 1.0)

I’ve always been a diligent student, so my parents never complained if I was spending too much time in front of my Commodore 128. After all, it actually was the mid-’80s and I was attending a tech school to get a diploma in computer science. Other kids were not as lucky since it is indeed […]
