That game DoorDoor looks quite fun. Would be interesting to see how it compares to the MSX version.
Many of the Tutor games are rather of poor quality, but this one might look worth converting to the TI-99/4A.

Could you do a short video on DoorDoor? Would be a primer as I havent found any Youtube video of this game in the Tutor version.

Thank you for posting the video. Very nice!

So this is a homebrew for the tutor? If that is the case I wonder what it would take to get it to run on the TI.
Should be possible especially as source code is then available.

Is it a homebrew from 1984 [edit: as the video shows]?

This is a homebrew for the jp original pyuuta by mr tiny-yarou in 2017. And I've made the binary patch for us tutor. The source code is not available in public.

Tanam1972's flash based cartridge and original 16k based boards are 'multi-carts' in that they have 3 jumpers each to allow selecting 1 of 8 banks in the chip to address. The flash based board uses a 256k 29F002 PLCC chip, for 8 banks of 32k byte roms. The 16k board, uses 27C512 eproms for 8 banks of 8k, or 4 banks of 16k roms.

Hi

I've ported G-BASIC YAKYUKEN to RAM & ROM Cartridge2 and SEGA MEGADRIVE with GCC.

The source code is available ; )

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:

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

The Tomy Tutor looks more like a Basic Computer 99/2 with more RAM and a VDP 9918A ;-)

 

I own a Tomy Tutor (US), a Pyuuta (Japan),  a Pyuuta Jr  and a dozen of cartridges.

Well yes, but the Tutor runs GPL which the 99/2 doesn't, isn't it?

For sure, but the Tutor lacks of a PSI as the 99/2. As very cheap computers, they also share a poor quality, poor electronic design, a unuseable keyboard for programmers.

What do you mean with PSI? I am not familiar with this word.

There was a Tomy Tutor MKII released in Japan only. It featured basically the same computer, running a better keyboard (and some different ROM?).

The Tomy GPL runs from Rom Chips, not Grom Chips.

PSI = Programmable System Interface, the function of the TMS9901.

Thanks for that. Didn't history show, that the TMS9901 actually combined two functions in one chip and therefore made it more expensive than required, once you added additional ports? So each Port got its own TMS9901 chip even though there was no additional CRU functionality required. At least I remember hearing some engineers complaining about that fact.

Isn't the DS990-1 also not using any TMS9902, TMS9901 or TIM9904 chips on its boards?
