Building the ReAmiga from scratch. Part5 Final part!
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

Building the ReAmiga from scratch. Part4
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:
Building the ReAmiga from scratch. Part3
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).
Building the ReAmiga from scratch. Part2
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:
Building the ReAmiga from scratch. Part1
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:
ReAmiga 1200 Erratapost
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)
Sigh.. Phase5 .. AGAIN
Well I know I told I would not write more about Phase5..
Just a quick update.
Salvador. the “owner” that also have been banned from Facebook. (both personally and companypage)
he have done (C) strikes about me on FB from fake accounts and Youtube. I have reported those claims as fake. but it is hard to talk to something else than BOTs..
So videos of me sanding the bppc PCB showing it is lacking connected ground etc is removed.
HOWEVER! they are all saved: so links to them from my local own server:
Reverse engineering of the Blizzard 1260 PCB
Well. We all know about the “new” Phase5.. he sold me 2 of the Blizzard PPC2 PCBs that I found out was faulty.. no ground connected. and he refused to refund or send new working pcbs.
And at Amiga32 he showed the Blizzard 1260 PCBs. saying that they would go to production any day.
now still one year after.. no production. so this summer I started to actually do a reverse engineer of it, just like I done with the A3640 and Amiga 1200..
Building the ReAmiga 1200 from the ground and up! Part1
I decided to do a writeup of my build of my personal ReAmiga 1200 using NOS parts.
my plan was first to tell exactlty where all signals get up etc. but unfortunally this would simply take so extremly much time so I do more like “function by function” instead.
First, I decided that I wanted to go all BLACK!
Moving components from a dead A1200 to an ReAmiga 1200
This is a small writeup how to move components from an dead Amiga 1200 to a ReAmiga board. (and basically the same as how to build one)
First of all I want to excuse the BAD soldering on the pictures here as I was out of solderwire and all I was able to get was leadfree crap.
and DAMN it is CRAP so solderjoints looks like I am drunk when soldering.
Remember this is NOT a SMD Soldering tutorial.
