Bandai TV-Jack 1000

Hi folks!

It's been quite a while i haven't posted here (about 8 months) but i haven't closed this blog and neither the others. OK so let's go to the topic: the Bandai (Video Mate) TV-Jack 1000.

I have received 2 days ago some electronic games and game consoles from Japan and since this game
console is going to a long-time friend game collector in the U.S., i thought i would take pictures (and tested it of course) before it hits the road to the "BBQ" state. ;)



It's is quite small and that is understandable as space in Japanese homes is usually small (rather compacted). Even if all the writing is in Japanese, it's really easy to figure out the buttons.

The one on the left top is the "Game Select" (Tennis, Hockey, Squash & Practice", the one on the left bottom is the ON/OFF switch (What gave this away ? LOL!!), the three buttons in the middles are (not in order as i didn't tested those): Ball Angle, Ball Speed and Automatic/Manual Serve aand the big one on the right is the "Reset" button.


The AC adaptor (also tiny) has a 9 volts DC (Direct Current) at 80mA (milliAmpere) with positive tip. 80mA ? That's almost nothing as power consuming and i'll show why later on...Oh and the same AC adaptor can be used on the TV-Jack 1500.

So before i open the beast (the game console)...here's my residential black beast! :P


She is called "Princess" as my daughter loved the Disney Princesses back then, as for me, i call her "Black beast" (when she done something wrong) or "Guidoune!"



This is the PC board of the TV-Jack 1000, not much electronic parts but the "All-in-one Pong chips" back then didn't needed much electronic parts to make it worked.


As you can see in this picture, the chip is a TMS1955NL which is a Texas Instruments "AY-3-8500-1" clone but this chip is almost half size then the generic one (this is the first time i'm seeing a TMS1955NL so small) and that's why the AC adaptor uses so few milliamps!


And here's the chip which colorize the games, the "SN76499N" also made by Texas Instruments, and the big grey thing underneath is the crystal.


And here's the back of the PC board.


And this is where i took the video signal: Pin# 8 of the SN76499N

And here's the screenshots of the games:

 TENNIS


 HOCKEY


 SQUASH


PRACTICE


So that's it for the Bandai TV-Jack 1000, it's a simple 4 game console but can play 6 games as the light gun games are not used (rather not connected) in this game console. So this one will be going to a good home quite soon! =)

"The Invasion" already started....

Hi folks,

Last year i only made one post and hopefully this year, it will be more.

Lee Romanow has made a brand new homebrew for the RCA Studio II called "The Invasion" and release it on January 1st, 2019 (that's what i call starting great the New Year!) Not only you can play it in black & white but also in color either in Emma02 (https://www.emma02.hobby-site.com/) or on a European clone (Soundic Victory, Conic M-1200, Mustang 9016, etc...just to name a few) as well ...err...if you have a RCA Studio II Multicart or made a (ROM or RAM) cartridge yourself.

Here's some screen shots made with Emma02:







So many thanks to Lee Romanow for this great homebrew!

But that's not all, he also released another homebrew on December 12, 2017 called "Fifteen Puzzle" to celebrate the 40th anniversary (1977-2017) of the RCA Studio II, here's some screen shots:



And again, thanks so much for another great game Lee! ;)

And finally, Lee also made in ROM files some of the demos included in the Programming Manual for Studio III on pages 10 to 12, like these:

* move1.st2 (moving a spot around the screen)
* move2.st2 (moving a spot around the screen, continuous, soundless spot motion)
* move3.st2 (moving a spot around the screen, continuous, soundless spot motion, no blinking)
* tone.st2 (generate key selected tone sequence)
* random1.st2 (randomly moving spot)
* showkey.st2 (showing a keyboard digit)
* random2.st2 (showing random bytes)

And as for where to download these rom files, i have just made a page on Archive.org to download the homebrews mentioned here plus also all the others brews made by Lee and Paul Robson. You can get them here: RCA Studio II homebrews (archive.org)

So have fun!! =)
