Philips Videopac+ G7400 RGB/Composite Hack – Repair – Recap

I have received a gift from my dear friend Andrea Pierdomenico a Videopac+ G7400 console with the BASIC Microsoft module and some cartridges that go into my collection of videopac cartridges.

This console running smoothly but with some problems.

  • Power button not working (as usual)
  • A capacitor of the power supply section has a broken leg.

The works that have been made:

  • Replacing the power switch with a compatible one.
  • Full recap of the power supply section.
  • RGB/Composite HACK for unparalleled video output.
  • RF Module Removal.
  • Shifted the 220V Power Cable into the hole of the RF antenna.
  • Two video cables (Composite-Audio / RGB-Audio)

Videopac+ G7400 RGB/Composite Hack (components that need to be added):

All the works that have been made are documented in the photos below:

Hyperkin Supaboy S (SD2Snes & Hardware Gallery)

Hyperkin Supaboy S (SD2Snes & Hardware Gallery)

I think it is totally useless to make another review of the Hyperkin SupaBoy S, there are hundreds on the net.

I wrote this short article and made a short video just to confirm the compatibility with the SD2Snes cartridge and take some photos of the inside of the SupaBoy S.

The SupaBoy S is not a Super Nintendo/Super Famicom emulator but a hardware clone of the original console, other consoles like the Yobo FC Twin had used the same choice.

This choice is absolutely winner because the compatibility with the software is very high, i have tested some games without any problems, including MSU-1 games with CD-quality Audio and Video Movies.

The only painful note is the video signal,  external and internal because BOTH are composite, which is not really the best, they could do better, maybe take the RGB signal immediately after the SONY CXA 1645M video encoder and make it available externally with a video connector.

I leave you to the photos and video.

Exidy Sorcerer II (DP1000-2) Repair

Exidy Sorcerer II (DP1000-2)

This computer is of a dear friend; Paolo Cognetti.

Short story of the repair:

I have checked the voltages and are correct, although a couple of capacitors on the power stage need to be replaced.

I have tried to turn on the computer and i have see immediately a problem, the screen is full of random characters, with the oscilloscope i have tried to see if i have data stream on the CPU (Z80), interrupts and so on.., nothing, it seemed completely dead, replaced.

The computer has started better then before but with some video glitches, raster lines scrolls from bottom to the top and some characters scattered on the screen. I double checked the voltages and i have realized that the 12v are gone and the 7812 warmed a lot, about 80 degrees after 2 minutes.

Almost all tantalum capacitors of 1uf and 33uF on the 12v line are shorted, i have decided to replace them all (22 pieces)

After the replacement of all tantalum capacitors and two electrolytic capacitors on the power supply stage the computer has started to work correctly but with some video problems, characters scattered on the screen, after replacing two Static RAM 2114 everything works perfectly, including the Basic Cartridge that until now had never worked.

Works that have been made:

  • Fixing broken Fuse Holder.
  • Fixing a cold welding of a capacitor on the power supply stage.
  • Testing Voltages.
  • Replaced CPU Z80.
  • Replaced 12 x Tantalum Capacitors (1uf)
  • Replaced 10 x Tantalum Capacitors (33uf)
  • Replaced 1 x Axial Electrolytic Capacitor (470uf)
  • Replaced 1 x Axial Electrolytic Capacitor (1500uf)
  • Replaced 2 x NMOS 2114 Static Ram.
  • Fixed the botton cover with two missing screws.
  • Cleaning the top cover using only water and a sponge.

Nintendo Classic Mini

Nintendo Classic Mini

I don’t want to make yet another boring review of the Nintendo Classic Mini, there are many on the net.

I will just say that is made very well, the 30 games included are emulated very well and seem bug free at least i have not found anyone.

The games selection menu is done very well, fast and intuitive.

The appearance is what impressed me, very beautiful and solid.

I have nothing else to say.
