Tomy Tutor...anyone?

Recommended Posts

Ooh, it is going to be difficult to be excited this Christmas... This just came in the mail from Japan:

Other than tapping composite video and audio, I will refrain from physical hacking on this item. I'll probably have to swap the powersupply, but I'll keep it tasteful.

The pyuuta ll emulator on floodgap supposedly can convert/generate wave files. But I haven't seen an archive anywhere. "Thee" archive out there says it had pdfs, but removed them in wait for higher quality ones. Boo.

Ok, so I'm torn up over my Tomy ぴゅう太 MkII from Japan. I want to power it on, but I don't want to modify it...

 

I'm thinking this technique may be sufficient for video/audio: http://www.retrofixes.com/2014/05/hook-up-famicom-to-american-televisions.html( using nintendo rf tv box, and channel 95/6 )

Just borrow a little nintendo discards.

 

And a Japanese travel step-down transformer. The power supply looks identical to the US Tomy Tutor, except I haven't counted the windings yet, and there is a chip that looks like the AC->DC bridge rectifier that has a different part number than the US model. The internet never learned of that part number as far as I can tell. So I'm hesitant to just try it out, as I would want to desolder it from the computer first and test it independently, and that would constitute modding the thing.

I also think I lost audio on my US tutor, when I went to just a +5v supply. maybe the -5v is used in the audio amp? I had thought it was just used in the expansion and cartridge port, but might have been wrong. I haven't had a chance to diagnose that yet. My US tutor power supply gives me audio, with a bad hum now... and the power supply has some physical vibration I can hear, so I'm not into running with that. I'm thinking about using a picoPSU and a 7905 voltage regulator to bring the -12v down to -5v.

My US Tutor had a slightly faulty keyboard ( 1 and 2 didn't work ) and my efforts to fix that broke most of the rest of the keyboard... So a few months back I designed a pcboard replacement for cherry switches...

 

https://github.com/jedimatt42/TomyTutorKeyboard

 

I decided to use it as a test board for a Chinese pcboard fab. JLCPCB. Came out nice... and works!

 

I haven't figured out how exactly I'm going to support and mount it in the case... but I'll get there.

 

Here's a pic:

The layout is mostly not modified, this is just switches in the same matrix as the original keyboard. Only two functional differences:

 

* I moved the return key to where it should be.

* I added a second shift key and set them where they should be.

 

Everything else is just as unique as it was. Which means I need to find a good technique for adding labels to the keys. I'm using standard windows 10?key key-caps. So I'll have to do some labeling magic.

 

A horrible waste of money, except now I've done it!!! icon_smile.gif

 

Oh, underneath, I removed the plastic ribbon cable seat from the motherboard, and just put a row of 16 header pins in its place. Likewise the keyboard has a row of right angle headers on the underside.

Nice, a Tomy Tutor Pro!

 

(for comparison, the mostly unrelated Sord M5 Pro used a rubber keyboard just like the regular Sord M5 which I think is a shame for a computer adding the "Pro" keyword to its name)

I considered porting my TI-99/4A homebrew version of Pitfall! to the Tutor.

Then I thought who's gonna play it. There are no homebrew PCB's for that machine, so only emulator would be possible for now.

 

I wonder how many Tutor machines there's still out in the wild.

The Others has Pitfall 2 available for it.

There is a Yahoo Group for the Tutor and Pyuuta. The author of Floodgate is on there. Recommend everyone join. We are trying to re-engineer the expander unit so the 3D games can be played.

 

The post here with the second version of the Pyuuta. In the CoCo world, we call that keyboard the Melted Keyboard. Same manufacture as CoCo. Atari computer expander also had that keyboard in ads.

Tanam1972 has reproduced the adapter.

I can't figure out how to use Yahoo Groups. I've tried. I have a cognitive disconnect. It makes me sad, as there are other things locked up in Yahoo I can't access. I've tried, had help... It didn't help...

 

You guys should all come over here.

I'm talking about the Add-on.

"This addon is used to play special 3D games. It is connected to the expansion port and then the 3D game cartridge must be inserted in this module cartridge slot."

Yep, that's what I'm talking about too. Let google translate have at the page, and then read on...

 

From Tanam1972's page that I linked:

 

Pyuta mk2 version upgrade adapter
  • It is a game adapter that makes it possible to execute 32 KB ROM etc. with expansion slot of the first generation
  • When you write the BIOS to the 27C512 with the ROM writer, it upgrades to mk2
  • It can not be used with Pyuta Jr / mk 2. It is exclusively for the first generation of Pyuta

With this adapter, my US Tomy Tutor can play the 32kb roms ( special 3D cartridges ) Maybe not so clear from description. But the first bullet hits home. The rest is google translating technical jargon poorly. Anyway, I have this. It works.

Ah, gotcha! Very sweet. I should have understood... having lived in Japan. I will have to build/buy it.

Looking at the gerbers, I assume that is just to build his dev cartridge. I didn't look at the other files in the ZIP. Or do we need to order the other gadgets direct from him?

 

 

I emailed him to order... he is also Tanam1972 here on this forum.

 

He has some other pages on his primary 'blog' like site, but it is much harder for me to navigate, but this is where he usually posts design details... Here is a sample: http://d.hatena.ne.jp/tanam/20180312/1520859313

 

It looks like he has built a 9938 or 9958 board for the Tomy as well, if you look him up on Twitter.

- Games are selectable with DIP-Switch

- Fit's inside a Megadrive Cartridge (YES, a Megadrive-Cartridge fits perfectly inside the Pyuuta/Tutor)

Not that I have a Tomy Tutor so I'm not in the market, but I would suppose the same multicart might be possible to fit in a Famicom, SMS, MSX, Sord M5, Casio PV-1000/PV-2000 shell too (though the last 3-4 are so uncommon that it would be heresy to sacrifice a shell for this purpose).

The Others has Pitfall 2 available for it.

Do I understand correctly that there is a Pitfall 2 port available for the Tutor?If yes, are there any videos or pictures available?
