The rom files posted here will run on a standard Intellivision. The graphics will be messed up as seen at the end of the video. There's no way to add the extra gram through the cartridge port. Someone would have to rewrite the program to use less gram if that is possible.

Thanks for that mr_me & Lathe26. :thumbsup: :thumbsup:

Sweet dude. I've already got some encouraging news but I need to make one small tweak to the ROM to make it work on a TutorPro (which I just call an INTV88 motherboard; stealing from others here).
 
If this checks out on a few more consoles, I think we have a one-step TutorPro/Tutorvision detection ROM :)

I -FINALLY- got around to running this ROM (laptop rebuild + work + street walking kept me busy) and it worked great on my system. Thanks!

This is the highest serial number for model 3504 A in the database and it's branded "INTV System III".

A 171447 Canada Steve Jones

I always thought that even if they were to use the same tutorvision mainboard in these Intellivisions there was a chance these boards might be jumpered to disable the extra gram. I'm not sure if there is such a jumper. And I'm not sure if they were aware of the incompatibility with extra gram; it affected very few cartridges. There also seems to be some evidence that some INTV systems had Intellivision II execs in them. I always wondered what that board looked like.

 

just tested this System 3 today, took a while to find as it is in an older Intelly 1 box, sadly it's an intelly 1 inside too.

Thanks, and I'm guessing the serial number prefix is RH and not A ie. it's made in Hong Kong. Looks like the last Intellivisions were made in USA serial numbers A031xxx.

On a side note, what is that little TV screen you have? That would be perfect for my workbench!

I found it at a thrift store.  It's an RCA RTV86073.  Looks like there are a bunch available on eBay.

I have a Super Pro that is a full Tutorvision but the graphics display as blocks. Text shows fine. Has anyone heard of this issue? Does anyone have an idea what it would take to fix?

Desoldering the current GROM chip and soldering in a Tutorvision GROM chip.  Obviously, Tutorvision GROM chips are very rare.

 

I think I misunderstood on the first reading.  Do you mean that the images are look blocky / goofy but the text font looks rounded like DOS's CGA/VGA font (rather than the text looking like the normal blocky Intellivision font)?

Are you talking about the graphics of Intellivision roms or Tutorvision roms?

Rather than keep people in suspense, here's my analysis of the Super Pros on eBay.

 

These items that show signs of being or not being a Super Pro Tutorvision.  In some cases, sellers have inadvertently taken photos that help diagnosing which bucket the console falls into.

Super Pro System    A 7940      Metal shielding through vents
    https://www.ebay.com...04/292319947898
Super Pro System    A 8244      Not a Tutor Pro, visible circuit board doesn't match
    https://www.ebay.com...e-/282634828110
Super Pro System    A 8800      INTV88 capacitor seen though vents
    https://www.ebay.com...04/173004152474
Super Pro System    A 11403     Mattel font, Hockey shows 159 pixels width
    https://www.ebay.com...on/311950478740
Super Pro System    A 16690     Mattel font
    https://www.ebay.com...on/132339644830
INTV System III     RH 094516   Mattel font, Baseball shows 159 pixels width
    https://www.ebay.com...ed/122838406709

 

In a nutshell, 8800 is a Super Pro Tutorvision, 8244 might be, and the rest likely aren't.  This assumes that there not other undiscovered combinations of Tutorvision parts (ex: maybe they later created a metal shield, maybe some had the Mattel font / GROM, etc, etc).

 

Here's another serial number added to the list:

 

Super Pro System(?)    A 008598      Not a Tutor Pro, it is a INTV 1987 REV A board with a black metal shield

    https://www.ebay.com...le/302897947793

 

JoeZ's Tutorvision Reverse Engineering doc has been updated with this serial number.

Unfortunately, 8652 is a non-functional unit.  It only displays a solid green screen when you turn it on (tried the usual cartridge wiggling, cleaning, etc).  On the upside, the video does glitch when reset is pressed so there is something partially working.  Some repair work is likely necessary.  Minor: the red LED does not light up either.

 

Here are some photos:

It looks like the STIC1A ASIC is not fully seated.  At least from the photos, it appears that the corner nearest the "A" in STIC1A is a bit raised.

 

If you have a PLCC extraction tool, I'd say "pop it out" and have a look at both sides.  (And if you do, take a photo of the bottom if there's anything interesting there.)

 

The EXEC (RO9580/P586) I believe is just EXEC 1, not the full WBEXEC.  But, it's a 9580, so it has capacity for 8K decles.  I wonder if they put anything in the other 4K?  P587 is the WBEXEC.

 

The EXEC is socketed, which is interesting in its own right.  Skippy (the first board I analyzed) had it soldered in.

 

This is date code 8912, which is the earlier of the two date codes we've seen.  I think we've seen 8912 and 8930.  IIRC, we haven't seen other date codes.

I wonder if this one can be combined with the one I gave to intvdave to make a complete working unit? Depending on what happens to be wrong with each, that is.
