Commodore TV Game Model 3000H (Pong Clone)

September 21st, 2014 No comments

I thank my friend Giacomo Vernoni for having given me this console that i was looking for a long times. This the link of the Giacomo blog where you can find a complete review of this console with some beautiful photos.

Gallery:

Following Commodore’s acquistion of MOS technologies (famous for producing the later 6502 chip for the PET), the Pong-like TV Game consoles 2000K and 3000H made their appearance.

The 3000H console features two paddles (sliders), one internal and one connected by wire (with 2 additional optional sliders); 9VDC or battery power (6 AA batteries required, yes it can run on batteries!).  It generates its own sound with the built-in speaker and can play 4 games: Tennis, Target (with an optional light gun), Football and Squash.  There is also a gage for difficulty level (handicap), and another for the number of players and other settings.

The cool thing is that the core chip, the MOS 7601 (the last of MOS’s Pong-chip line) read game instructions from a special ROM which appears to be internal to the chip, making it stand out from the other Pong-clones that had the game hard-coded into the system’s logic

However, because graphics and sound are also generated directly by the 7601 and are hardwired into the chip’s logic, it meantthat special variants had to be created if a special display was required for an arbitrary application. Thus, the 7601 in the TV Game series, while being programmable in a crude sense, is hardwired to generate the graphics for the TV Game series’ internal games only and cannot be used into drawing other kinds of shapes.

Games available were the following four:

  • Game mira (playable with an optional optical gun )
  • Tennis
  • Football
  • Squash

Repair Commodore Amiga 3000 motherboard with Battery leakage

Repair Commodore Amiga 3000 Motherboard with Battery leakage

There was once a motherboard of an Amiga 3000/25 devastated of the Battery acid where missings all the socketed components and others are unsoldered and recovered for other things.

The situation was not exactly the best one, in other words … was going into the box of spare parts.

I made the impossible, i have cleaned, scraped and rebuilt many tracks of the pcb corroded by the battery acid and i must say that with lot of patience i have repaired the motherboard giving a new life to this Amiga 3000/25 that he had no many chance to come back to work

SD2Snes Firmware v0.1.7 (Beta/Preview) released

September 19th, 2014 No comments

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Full Changelog:

  • In-game button combinations are in effect. See the table below for the key mapping. Note that some games show glitches with the in-game functions in place. I added an additional feature to temporarily disable them in case of game glitches (e.g. Secret of Mana hangs at the Squaresoft logo, displaying only garbage). I’m not entirely happy with the button choice but it will do for now. ;)
  • LED blink codes for file system errors – e.g. in case the SRM file cannot be saved this will tell you that something’s gone wrong. The blink codes are yet to be listed.
  • Also the sd2snes will retry saving until it works so you have the chance to swap out the SD Card. In that case the directory structure must be present where the sd2snes expects to save the file.
  • “Screen saver” – in the menu, the screen is darkened after some idle time to reduce wear on CRT and plasma screens.
  • Memory sharing between SNES and the sd2snes CPU is greatly simplified (The FSM is reduced to only 5 states instead of 18) and timing is more relaxed. This should help with stability on a wider range of consoles.
  • On-the-fly file browsing. Also shows a little “loading…” window when loading directories/files.
  • Windows are now blue so they stick out better in front of yellow directory listings.
  • Cx4 data ROM is now embedded in the FPGA configuration – no more need for the external file cx4.bin.
  • Initial Satellaview clock is back to 18:00:00 from 18:05:30.
  • SD cards can be hotswapped. Currently there is no automatic refresh of the file list so tapping reset on the SNES or changing the directory is necessary to get the new contents.
  • The status line is moved upward a few pixels so hopefully it doesn’t get eaten by overscan.
  • Navigation: When scrolling page-wise with the right D-pad arrow, the end of the file list is now aligned to the bottom of the screen.
  • Navigation: The shoulder buttons can be used to jump to the beginning/end of a directory listing.
  • Bugfix: some compatibility issues with a number of games. (Super Play Action Football (S-RTC interference), GP1 Part II (WRAM initialization), Human Grand Prix (mapper detection bug))
  • Bugfix: properly initialize FPGA state machine (on some consoles the menu failed to start at all)
  • v0.1.7 final will contain menu items for various configuration settings and a cheat interface.

In-game button mappings:

  • L+R+Select+Start = Reset game
  • L+R+Select+X = Reset to sd2snes menu
  • L+R+Start+B = Disable cheats
  • L+R+Start+A = Enable cheats
  • L+R+Start+Y = Kill in-game routines (in case they interfere with game operation).
  • L+R+Start+X = Temporarily kill in-game routines (~10 seconds – if you need to get past a glitch but don’t want to lose in-game buttons)

Princess C64SD v3.0 by Manosoft

August 19th, 2014 No comments

Hi all, like one year ago Manosoft amazes us again, this time he did a great job of merging the ITS TAP Player module with the C64SD and from this merger comes the Princess, an interface with both previously released interfaces.
The Princess interface is elegant as only Manosoft can do, the box color has changed and is a white sand that matches perfectly with the whole 8-bit Commodore Home Computer series.

In addition to the color were also added new controls and visual led. Below the instructions of each command on the front/back side of the Princess interface.

Front side:

  • [1] Play/Stop switch for TAP file.
  • [2] Reset button.
  • [3] Disc Change button. (down/autoswap.lst)
  • [4] LED:
    • Yellow – Virtual Motor of the Tape.
    • White – Reading.
    • Red – General Error.
    • Green – Power.
  • [5] Floppy Drive Connector (IEC) Computer side.
  • [6] Connector Cassette side Computer
  • [7] Auxiliary Power 9v.

 

Back side:

  • [1] SD Card slot.
  • [2] Red Button – Setpoint tap file / (up/autoswap.lst)
  • [3] Dip Switch for selecting the Floppy drive Device (SD2IEC).
  • [4] Audio volume (monitor function) TAP Player.
  • [5] Mini DIN 8-pin connector to be connected to the tape port of the Commodore 264 series.
  • [6] Auxiliary Power 9v.
  • [7] Pass-through Floppy Drive Connector (IEC)
  • [8] Pass-through Tape connector to use with a Datasette 1530 or 1531 with a another adapter.

 

 

Like the previous C64SD v2.0 interface, the Princess has a pass-through connector for the cassette recorder and one for the Floppy Disk Drive.

I don’t forget to speak about the nice addition, a small Piezo Speaker to hear the sound of the bytes that are loaded with the TAP Player and also a nice “beep” that warn if the interface on power up working correctly.

Damiano alias “Manosoft” is a good manufacturer of 8 Bit peripherals and also a great friend. I take the opportunity of this article to greet Damiano and congratulate for this new interface for the 8-bit Commodore Home Computer series.

Soon will be available on the Manosoft website two new software packages (C64 and AIO)

“AIO” is an innovative system that will allow the creation of the SD Card of 4GB or higher in a few minutes from an image file created ad hoc.

On the Commodore 64 side was also written a new program called “MENU” with some utilities like the initialization of the SD Card for the Princess C64SD v3.0 interface.

The development of the TAP Player firmware with the SD2IEC protocol has been made possible thanks to the collaboration of Hawui1 promoter and developer of the ITS Module and some other things.

The Princess C64SD v3.0 interface will be available for sale in the next months on the Manosoft site.
