I bought a cheap sio2sd and put it into a Atari 1064case.
Inspired from http://atariage.com/forums/topic/175988-new-case-for-my-sio2sd/
Some dremel, hotglue and time…

Dezember 12th, 2017Today I tried to upgrade a new NES Mini Controller with the UWRC PCB from micro.
And it works great
left old uwrc Controller NES, right new NES Mini Controller

Dezember 7th, 2017
Today I revived a the holy grail of PC Engine Hardware a PC Engine LT.
Only 5 screws and remove 3 ribbons you will get the main PC Engine Board
Because of its age the Caps are brocken and need a replacement.
After some exchange in the power area it works again 
look how bad it looks because of leaking caps
how ugly it looks. Some alkohol for cleaning
exchanging of most caps to kerkos
after recap
jailbarfix too with replacement of 2 kerkos into: 4,7uF 16V or 25V
One Power Supply to rule them all
November 21st, 2017For testing old Computers you will need a lot of different power supplys with AC and DC Voltage.
I put them together and we got one to rule them all 
Meanwell RT-65B and a 9V AC Power Supply
9V /2100mA
5V / 5,0A
12V / 2,8A
-12V /0,5A
So it works @:
- Atari 8 Bit Computer like 600XL, 800XL, 1200XL, 800XE, 64XE, 130XE
- Atari 8 Bit Computer like Atari 400, 800, Atari 810, Atari 1050
- Commodore C64, C16, C64C
- Commodore Amiga 500,500Plus, 600,1200
- Commodore CD32, Commodore 1541 II
- Neo Geo 5V Unit

NeoGeo X battery failure
September 14th, 2017I was lucky to get a new NeoGeo X Console but the battery was brocken 
So i ordered a replacement and changed it …
Look at the blown up original battery (never used, brocken, crazy)
done
and its working …
Raspi in a Stick
August 20th, 2017raspberry modding is everywhere. So we put a raspberry in a NeoGeo Oldstyle Arcade Stick for presentation at GamesCom 2017, so the younger games can get in touch with the neo-geo Games and not only with the look. With the right feeling a original NeoGeo Controller
The position makes it possible to use the onboard USB Ports and network connector.
First some dremel work to make it fit into the neogeo arcadestick case
then a hdmi slim extension and a usb cable
As the NeoGeo X Controller is a standard USB Controller it was possible to connect the usb part directly to one usb connector of the pi
in the future it could be possible to make the buttons directly to GPIO Ports
So it looks great
