intvdave Posted January 11, 2018 Share Posted January 11, 2018 Thanks, that's what I thought. Would be nice if it was....as I organized the dumping of the 1st 2 games and the console bios so they all could be made available to everyone. I do not know AA ids so I do not know who you are but it was my dumper that dumped the 2 games. I also know others that were involved in making this happen. Please private IM me. I am curious what involvement you had / who you are. Quote Link to comment Share on other sites More sharing options...
First Spear Posted January 15, 2018 Share Posted January 15, 2018 It would be cool (?) to have some kind of detection that could be done in/through IntyBASIC so a subtle change could be made to font or graphics in some way.... Hmm, StudioVision will spot the existence of the extra GRAM in a TutorVision and switch to full screen mode, does this mean it is the first Tutorvision specific homebrew?

Checking for the extra GRAM *should* be as simple as writing to the expanded RAM, and seeing if the value persists. Try a POKE to $400, then a PEEK.

+Lathe26 Posted January 16, 2018 Share Posted January 16, 2018 Checking for the extra GRAM *should* be as simple as writing to the expanded RAM, and seeing if the value persists. Try a POKE to $400, then a PEEK. See what you get Detecting the extra GRAM is almost that simple. There are 3 known configurations out there: Normal Intellivision or normal Intellivision II GRAM: 0.5KB located at $3800-$39FF and mirrored at $3A00-$3BFF, $3C00-$3DFF, $3E00-$3FFF Modified Intellivision II GRAM: 1KB located $3800-$3BFF and mirrored at $3C00-$3FFF. I'm only aware of JZ performing this modification as a one-off experiment. Tutorvision GRAM: 2KB located at $3800-$3FFF A IntyBASIC program could POKE the values 4, 2, 1 into memory locations $3E00, $3A00, $3800, respectively and in that order. Then it would PEEK the value at memory located $3E00: 4 -> 2KB GRAM (Tutorvision) 2 -> 1KB GRAM (modified Intellivision II) 1 -> 0.5KB GRAM (normal Intellivision or normal Intellivision II) At least that's my understanding from the documentation. I could be wrong. 1 Quote Link to comment Share on other sites More sharing options...
freewheel Posted January 16, 2018 Share Posted January 16, 2018 Right. I was thinking of the expanded system RAM, not GRAM. And I goofed anyway - $400 gets used by the Inty 2 EXEC. Not sure what the behaviour is there, if you try what I suggested Quote Link to comment Share on other sites More sharing options...
+Lathe26 Posted January 16, 2018 Share Posted January 16, 2018 I and David Harley dumped the roms of 3 tutorvision games: - Geo Graphics - Map Mazes - Shapes In Space We could produce these games with box, manual and all, BUT they would work only on tutorvision consoles and on some (not all) of Super Pro System consoles. So, they would be mainly pieces for collectors (but could be played on emulator on pc). If we do it, anyone would buy them? Thanks:) Alessandro Throwing WAAAAAAY back to the original post, it might be worth considering whether to sell the games in original and/or with 1/2 the WBEXEC merged with it (or offer a bootup menu to select between the two). Not sure if this helps or only will add customer confusion. Just thinking out loud here... Quote Link to comment Share on other sites More sharing options...

freewheel Posted January 16, 2018 Share Posted January 16, 2018 The last techie test I ran was the ROM from Test Cart version 4.1b (the MTE-201 test cart has an older version 3). Summary: Tests fail, but isn't surprising. The 4.1b cart has a cool feature where it tries to identify the system it is on. In the lower left, "O2" is displayed. This value changes based on what system you run it on. The values I've seen there are: M1 - original Intellivision EXEC M2 - Intellivision II EXEC (going from my memory, I'm 99% confident) O1 - Sears Intellivision EXEC O2 - my Tutor Pro (hmmm...) Since we're bringing back old posts... You get O2 on an INTV2 EXEC as well. Which is kinda interesting that your TutorPro gives the same result. I guess it's seeing stuff loaded at $2000 and just going with it. Quote Link to comment Share on other sites More sharing options...

Steve Jones Posted January 17, 2018 Share Posted January 17, 2018 There's a guy on facebook in the Intellivision Invasion group named Steve Ettinger who says he programmed 5 Tutorvision games including these ones, you guys should get in touch with him.

freewheel Posted January 18, 2018 Share Posted January 18, 2018 Anyone wanna guinea pig something for me? Especially *cough* Lathe *cough* as I'm curious what his system says with this ROM. I whipped up something that in theory tests all of the various chips that make a Tutorvision (or a TutorPro). I can't actually test for Lathe's system (it has the motherboard but not the EXEC, which can't currently be tested in an emulator) so I'm really interested if I got this right. This'll also detect anyone with a SuperPro or INTV III, that has the INTV 2. At least I think so. Those are out there, so it's worth knowing in case you want to play Donkey Kong and just can't. If someone could try this on a full-blown Tutorvision that'd be swell! tv_check.zip Quote Link to comment Share on other sites More sharing options...

Feel free to ping / reminder me next week if I haven't reported back by then. 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 tv_check_fixed.zip 2 Quote Link to comment Share on other sites More sharing options...
Chuck Gill Posted January 19, 2018 Share Posted January 19, 2018 Neat It means you have the Tutorvision GROM. Next step is to try to play Worm Whomper on it. Apparently the worms won't look right, if you have the full board. Also weren't the Tutorvision ROMs released on one of these threads? Couldn't a person just put them on an LTO Flash! and see what happens? Brilliant idea, I did release the roms of the two games I have. 2 Quote Link to comment Share on other sites More sharing options...
mthompson Posted January 19, 2018 Share Posted January 19, 2018 Chuck: have you been able to try Freewheel's "Tutorvision Checker" ROM (above)? You're probably the only one who can see what it reports when run on an authentic World Book Tutorvision. Quote Link to comment Share on other sites More sharing options...

freewheel Posted January 20, 2018 Share Posted January 20, 2018 Who can do this? Any programmer, and probably anyone who can put a ROM onto a cart. There may be a better way to handle this though. We'll see. Either way, it's definitely possible to release games for the Tutorvision *and* INTV88 (the almost-Tutorvision that Lathe26 has).

mr_me Posted January 20, 2018 Share Posted January 20, 2018 (edited) If you can activate the extended rom on the cartridge programmically, then you can first detect if it's on the mainboard and then turn it on so it's all automatic. The term INTV88 comes from the fact that Tutorvisions [and a few INTV Intellivisions] have a big "INTV 1988" label stamped on the mainboard.

+Lathe26 Posted January 24, 2018 Share Posted January 24, 2018 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/itm/Intellivision-Super-Pro-System-Very-Rare-Consol-Video-Game-In-Box-Model-3504/292319947898 Super Pro System A 8244 No shield (but board is inconclusive) https://www.ebay.com/itm/Intellivision-Super-Pro-System-III-INTV-3-Video-Games-Model-3504-Console-Bundle-/282634828110 Super Pro System A 8800 INTV88 capacitor seen though vents https://www.ebay.com/itm/Intellivision-Super-Pro-System-with-21-Games-Console-Video-Game-Box-Model-3504/173004152474 Super Pro System A 11403 Mattel font, Hockey shows 159 pixels width https://www.ebay.com/itm/Intellivision-Super-Pro-System-Console-Video-Game-System-Great-Condition/311950478740 Super Pro System A 16690 Mattel font https://www.ebay.com/itm/Intellivision-Super-Pro-System-III-INTV-3-Console-29-Games-See-description/132339644830 INTV System III RH 094516 Mattel font, Baseball shows 159 pixels width https://www.ebay.com/itm/Intellivision-INTV-III-3-System-Console-Tested/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). After further discussions, ser# 8244 is NOT a Tutor Pro. JoeZ pointed this out when he took a closer look at the photos. 1 Quote Link to comment Share on other sites More sharing options...
Utopia Posted February 8, 2018 Share Posted February 8, 2018 So, Will it ever be possible to play these Tutorvision roms on a standard console through LTO Flash? I,m thinking some magical software is needed to make this happen. Quote Link to comment Share on other sites More sharing options...
mr_me Posted February 8, 2018 Share Posted February 8, 2018 (edited) 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. http://atariage.com/forums/topic/274349-tutorvision-games-on-real-hardware/ Edited February 8, 2018 by mr_me 1 Quote Link to comment Share on other sites More sharing options...
