RGB + Synch Amplifier Circuit for Sega SG-1000 II (Mark 2)

September 2nd, 2012 4 comments

This is a Video RGB Hack for the console Sega SG-1000 II (Mark 2).

The Sega 315-5066 Video Chip inside the Sega SG-1000 II (Mark 2) used in the latest version of the console uses two video output formats: NTSC Composite video (converted to RF), and RGB (not connected).

The RGB Video is the stuff from which all other formats are born. Once your RGB is tapped it can be easily converted to Component or S-video, giving stunning output far superior to what the Sega SG-1000 II natively offers (only RF).

There are several caveats, of course. The biggest is the quality of the RGB output – it’s not very bright, and will result in an image without much contrast, so you will probably need to add an amplifier. Even on monitors that display a very good image without the amp you’ll sometimes find the sync signal needs an amp to generate a stable image.

I have used the same RGB/Sync Amplifier used on the PC-Engine, components and the Original schematic are shown below.

Schematic:

Components:

  • 4 x 2SC1815 (Transistor)
  • 4 x 220 μF 16v (Electrolytic capacitor)
  • 4 x 10 μF 16v (Electrolytic capacitor)
  • 4 x 75 Ω (Resistor)
  • 8 x 10 KΩ (Resistor)
  • 1 x 300 Ω (Resistor)

 

 

The three photos below show the connection between the RGB Amplifier and the PCB of the Sega SG-1000 II.

WAV-PRG v4.0 Alpha5 by Fabrizio Gennari

August 30th, 2012 1 comment

WAV-PRG is a program able to create a .TAP file or Commodore 64 tape from a C64 emulator file (.PRG, .P00, .T64), and create emulator files (.PRG, .P00, .T64) from a Commodore 64 tape. The latter can only be done if the tape is in a format supported by an existing plug-in.

CBM prg Studio v2.5.0 released

August 20th, 2012 No comments

CBM prg Studio Version 2.5.0 is released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.

CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 / VIC20 or PET if you’re feeling brave and have the right kit.

CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.

It was also a good opportunity for a face lift and to add some new features, such as:

  • Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
  • Tabbed MDI.
  • Syntax highlighting.

What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.

Major new features:

  • Addition of PET 2001/4000/9000 computers.
  • Addition of VDC mode for the C128′s screen designer.

Bugs fixed:

  • Screen designer clear screen function.
  • Basic program auto-complete not working if assembly source in same project.
  • New Project wizard occasionally create wrong project type.
  • Some screen editor undo/redo issues.
  • Truncate the paste buffer in screen designer.
  • RESTORE keyword not being renumbered.
  • Occasional problems when closing edit windows.
  • Crash when the output window is closed and a source file has breakpoints.
  • ‘ifdef’ directive not recognised.
