Experimental Tomy Tutor driver
This computer is known as Tomy Tutor in US, and as Grandstand Tutor in UK.
It was initially released in Japan in 1982 or 1983 under the name of Pyuuta
(Pi-yu-u-ta, with a Kanji for the "ta"). The Japanese versions are
different from the English-language versions, as they have different ROMs
with Japanese messages and support for the katakana syllabus. There are at
least 4 versions:
* original Pyuuta (1982 or 1983) with title screens in Japanese but no
Basic
* Pyuuta Jr. (1983?) which is a console with a simplified keyboard
* Tomy/Grandstand Tutor (circa October 1983?) with title screens in English
and integrated Basic
* Pyuuta Mk. 2 (1984?) with a better-looking keyboard and integrated Basic
The Tomy Tutor features a TMS9995 CPU @10.7MHz (which includes a
timer/counter and 256 bytes of 16-bit RAM), 48kb of ROM (32kb on early
models that did not have the BASIC interpreter), a tms9918a/9929a VDP (or
equivalent?) with 16kb of VRAM, and a sn76489an sound generator.
There is a tape interface, a 56-key keyboard, an interface for two
joysticks, a cartridge port and an extension port. The OS design does not
seem to be particularly expandable (I don't see any hook for additional
DSRs), but there were prototypes for a parallel port (emulated)
and a speech synthesizer unit (not emulated).
The Tutor appears to be related to Texas Instruments' TI99 series.
The general architecture is relatively close to the ti99/4(a): arguably,
the Tutor does not include any GROM (it uses regular CPU ROMs for GPL
code), and its memory map is quite different due to the fact it was
designed with a tms9995 in mind (vs. a tms9985 for ti99/4), but, apart from
that, it has a similar architecture with only 256 bytes of CPU RAM and 16kb
of VRAM.
While the OS is not derived directly from the TI99/4(a) OS, there are
disturbing similarities: the Japanese title screen is virtually identical
to the TI-99 title screen. Moreover, the Tutor BASIC seems to be be
derived from TI Extended BASIC, as both BASIC uses similar tokens and
syntax, and are partially written in GPL (there is therefore a GPL
interpreter in Tutor ROMs, although the Tutor GPL is incompatible with TI
GPL, does not seem to be used by any program other than Tutor Basic, and it
seems unlikely that the original Pyuuta had this GPL interpreter in ROMs).
It appears that TI has sold the licence of the TI BASIC to Tomy, probably
after it terminated its TI99 series. It is not impossible that the entire
Tutor concept is derived from a TI project under licence: this machine
looks like a crossbreed of the TI99/2 and the TI99/4 (or /4a, /4b, /5), and
it could either have been an early version of the TI99/2 project with a
tms9918a/99289a VDP instead of the DMA video controller, or a "TI99/3" that
would have closed the gap between the extremely low-end TI99/2 and the
relatively mid-range TI99/5.
Raphael Nabet, 2003
TODO :
* debug the tape interface (Saved tapes sound OK, both Verify and Load
recognize the tape as a Tomy tape, but the data seems to be corrupted and
we end with a read error.)
* guess which device is located at the >e600 base
* find info about other Tutor variants
Interrupts:
Interrupt levels 1 (external interrupt 1) and 2 (error interrupt) do not
seem to be used: triggering these seems to cause a soft reset. XOPs are
not used at all: the ROM area where these vectors should be defined is used
by a ROM branch table.

********
This is a handheld unit with 12 'chiclet' buttons. The keyboard has E800, EA00, EC00, EE00 scanned,
although 2 of these rows have no keys. TUTOR carts will run, however since most of them ask for
A=AMA, P=PRO, these keys don't exist, and so the games cannot be played.
