The Mark 2 was a commercial failure, sold some months before Tomy decided to pull out of the Home Computer market. Very few people used it. The MKII has a better keyboard (however lower than the 99/4A, /5 and /8 keyboards) but Tomy shot itself in the foot making a stupid choice by killing the video composite and audio connectors. Using the computer on a TV set via the RF signal, in 1984, is an abomination.  TI made the same choice with its 99/2 Basic Computer.  As soon as, I received mine, I modified it to get a composite signal, much better.

Thanks Ksarul, sounds like a plan. I'll contact you when the Pyuuta has arrived.  ;)

 

Did you play PITFALL! on Pyuuta? If no, then I can send you one ; )

Hi people,

 

today I bought a Tomy Pyuuta Tutor (japanese version) for cheap (118 USD including shipping) 

Normally they are a lot more expensive, I've been watching ebay for more than a year now.

 

The idea is to tinker with it and I would at least like to see my Pitfall version running on it  ;-)

 

So the question is, can someone point me to the direction where I can get a homebrew cartridge board?

 

Also does anyone know, if it would be possible to turn a japanese Tutor into the american version by swapping ROM's ?

Ofcourse would be great if I can swap keyboard too, but I guess that won't be so easy.

 

Also have been wondering; what is the TI machine that comes closest to the Tutor? Would that be the TI-99/4a, TI-99/5 or TI-99/8 ?  :grin:

 

ok, people so a while a back I got the Tutor delivered from Japan. This is a though one, got it on ebay real cheap compared to the prices you normally see.

The thing is, it's in such a good condition. The operator manual looks brand new and I'm pretty sure the unit was never (or barely) used at all. Joysticks are in pristine condition too. This makes it hard for me to tinker with it.

 

Anyway I'm still in the process of getting a voltage step-up regulator so that I can run it in Europe. 

Here's some pictures. Oh, and big thanks to @tanam for his great gifts.  Really looking forward to play with these.

The cartridges have many similarities to the TI ones...

 

  • The back has an edged side like TI ones
  • The spring loaded piece
  • The bottom and the plastic 'clips' that hold the sides
  • The font on the labels "16 Bit Graphics Computer"

A TI Cartridge case will fit perfectly into the cartridge opening for a Tutor as well, as the thin part of the TI case is the proper size to fill the cartridge well on a Tutor.

Are the physical paths the same as well? I mean would it take a lot of effort to for example turn Ralphs final rom cartridge in a tutor compatible version?

I imagine it would be possible, but the pin out is definitely different. . .
