Tomy Tutor Photographs

The Pyuuta Section has even more photographs, specifically of the Japanese line! As for the vapourware peripherals, refer to the Purcell Pamphlet.

The Tutor itself. Click the image for a full-size .JPG (74K). The raised printing on the keys is evident by the glare.

You can also see a closeup of the keys (43K).

A thumbnail of the complete system. Clockwise starting at top left, main unit, Tomy Data Recorder, single joystick and joy controller set.

Here are images of the Tutor's box (click the thumbnails for larger views, 87K and 137K respectively). The second image is left at full resolution so that you can read some of the box copy.

I've also taken closer shots (without that annoying fill-in flash, sadly unavoidable due to the low light in my workroom) of the "witty kids" vignettes (120K) so that you can appreciate some of their totally spontaneous and not a bit written by professional advertising agencies quips on the front, and a better picture of the guy and girl using the Tutor (45K) on the back. Interestingly, the Tutor they're using is a much earlier version as you can see from the hard plastic RT key and the different power switch -- it may be a Grandstand or, more likely, a Pyuuta.

In the "witty kids" picture, an Asian boy states, "Now that I can simulate space flight, NASA's calling daily." The boy's name is Eric Jue (who contacted me out of the blue one day), and still remembers playing with the Tutor; apparently the kids who were photographed got a free computer and some games. Eric says, "I remember playing Traffic Jam and Hyperspace. I thought it was a great system at the time and I was disappointed it never caught on."

A thumbnail of the boxes for the joy controllers, the "joy stick" [sic] and the Data Recorder.

A thumbnail of some of my Tutor cartridges, including the Konami series.

A thumbnail of the Tomy Tutor manual. A neat design; it is spiral-bound and designed to sit easel-style so you can program with the book open in front of you. I wish more manuals were like that.

By the way, they reused some of the kids from the front box, with the exception of the very attractive girl on the far right, who was one of my early prepubescent crushes. Ah, geek love.

A thumbnail of the rear ports (a schematic of this is on the Scans page). Purple arrow indicates the power cord to the internal power supply; blue is the I/O port (bolted shut in this model); cyan is the joyport; green is the cassette interface; yellow is the monitor outputs; and red is the RF output.

This is the underside of the Tutor with the label and screw access. Click the image for a full-size .JPG (54K), or zoom in on the label (45K).

Okay, now that that's out of the way, grab your drill, hacksaw and hot glue gun. I'll wait.

With the screws removed from the back of the unit, very carefully separate the halves, and remove the keyboard ribbon cable (see below).

When the unit is correctly opened, the view should resemble the above (click the image for a full-size .JPG, 54K); the red arrow is indicating the keyboard ribbon cable's connector and where you'll be pulling the cable from (verrrry gently). Be careful of the wires to the power LED; I usually just turn the front of the unit over to the side to avoid having to pull them. If you must disconnect the LED, carefully note how it was originally hooked up, as it only works one way.

Undo the screws of the Faraday cage (there are several at its corners), take the RF shield off and put it aside to expose ...

... the Tutor mainboard (click the image for a full-size .JPG, 81K). The thumbnail has several coloured arrows pointing out notable items on the motherboard. The yellow arrow is indicating the 9918ANL VDP video chip (with its VDP RAM below it); the white arrow is indicating the SN76489AN sound chip (the topmost/leftmost chip of the Custom Logic Array); the cyan arrow indicates the power supply, which we'll come to in a moment, and the purple arrow indicates the power supply's connection to the mainboard. The 9995NL CPU is indicated by the green arrow.

The twin Tutor ROMs are indicated by the red arrows and are discussed in greater detail on the hardware page. Tutor-1 ("ROM 1" in the mock schematic), which also appears in the Pyuuta Mk II, is the ROM closest to the CPU.

Most distressingly, the power supply (the most frequent cause of failure in Tutors based on my experience with them) is internal. I suppose we should be grateful it's not actually integrated, or we'd be in even bigger trouble.

The above thumbnail (click the image for a full-size .JPG, 52K) indicates the 110V input with the white arrow, and the fuse with cyan. The fuse, as the full size image shows, is a 125V/1.25A rated fuse and looks fairly easy to find. If your Tutor has blown up and its power light won't come on, this would be your first thing to check.

To reassemble the unit, replace the RF shield/Faraday cage and secure it, then connect the keyboard ribbon *with correct lead polarity* and close the two halves together. Carefully turn the system over and replace the screws. Plug it in and make sure you didn't kill it. ^^
