PSOne recap

Februar 8th, 2018

I got a really new boxed PSOne and it didn’t work. It wasn’t play any disc :-(

So i decided to do a complete recap of the smd caps.


I used a lot of ceramic caps and for the 220u new SMD caps


And how wonderful, after recap it plays all CDs :-)

Here is a recap map I put the values of the replacement voltage often higher as the original values

UWRC NES PCB into a new NES Mini Controller

Dezember 12th, 2017

Today 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

you need to remove this here and make the led hole bigger and as usual the opening for the usb connector for loading


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

PCE_LT_ (11)

Because of its age the Caps are brocken and need a replacement.

After some exchange in the power area it works again :-)


PCE_LT_ (10)


look how bad it looks because of leaking caps





PCE_LT_ (8)


how ugly it looks. Some alkohol for cleaning



PCE_LT_ (6)



PCE_LT_ (5)


exchanging of most caps to kerkos



PCE_LT_ (4)


after recap

LT jailbarfix


jailbarfix too with replacement of 2 kerkos into: 4,7uF 16V or 25V





One Power Supply to rule them all

November 21st, 2017

For 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

Neo Geo AES 3-4 RGB Bypass

September 14th, 2017

here you find the pics for rgb bypass for a neogeo AES 3-4 PCB with THS 3714 amplifier.

No more bad pictures and no more jailbars with perfect picture level thanks to arcade-tv :-)

R1-R3 = 7.1k

R4-R6= 1.9k


NeoGeo X battery failure

September 14th, 2017

I 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)




and its working …

Raspi in a Stick

August 20th, 2017

raspberry 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
