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:

Cartridge shell for FinalGROM 99 – TI-99/4A

August 2nd, 2017 1 comment
Cartridge shell for FinalGROM 99 - TI-99-4A

Cartridge shell for FinalGROM 99 – TI-99/4A

I have fit in a best way the pcb of the FinalGROM 99 inside a standard cartridge shell of a TI-99/4a game.

As you can see from the photos the final result is good, there are still some minor imperfections but i’m very satisfied.

I have made three cartridges shells, one for me and two for my friends Ciro Barile of  TI-99 Italian User Club, Andrea Pierdomenico.

Some things about the FinalGROM 99:

The FinalGROM 99 supports ROM images, GROM images, and mixed images of up to 1 MB in size that use the write-to-ROM bank switching scheme. The cartridge does not require the Peripheral Expansion Box and runs on both PAL and NTSC consoles, including modified consoles with an F18A. It will also run on v2.2 consoles and enables those to run ROM-only programs.

The cartridge offers some advanced modes that provide RAM and GRAM to programs. It also allows a running program to reload another program from SD card or to dump its state to SD card. All firmware of the FinalGROM 99 can be updated by SD card.

FinalGROM 99 is released as Open Source Hardware under the CERN OHL license and the GNU GPL license. Both hardware design files and firmware sources are available on GitHub.

For more information about this project please visit the project homepage hosted at GitHub.

DiagROM Now supports Commodore A1000

July 30th, 2017 No comments

..from the author homepage:

I have updated the DAILY version now and it now supports the A1000 using a limited version of the DiagROM. I had to remove module-tests and test-screen.  but I guess that is not that important.

 Just use the A1kEVEN.bin and A1kODD.bin files and program to 27C256 proms and replace proms on the A1000 and you are ready to go.

Catweasel Z-II Mk2 (Urine CAT Cleaning)

Defect:

  • The card is not recognized by the computer.

Cleaning:

  • The Catweasel has traces of cat urine that with time has crystallized causing corrosion and short circuits.  I used the KONTACT PCC & Toothbrush to clean. I also checked the continuity in holes between pcb layers and traces in general.  Now it seems to work properly.

Peggy Plus (Scala MD100) v1.1 Recap

Peggy Plus (Scala MD100) v1.1 Recap

This Z2 card for Amiga has a problem of audio distortion on one channel. I have replaced all the tantalum capacitors, two of them in the Audio section.

Unfortunately i could not try this card, i did consider that could be also a problem of the NE5532  a Dual Low-Noise Operational Amplifier so i preferred put it on a socket, so it’s easy to replace if it is needed.
