I know this topic started out as an overclocking of the original Sally chip, but more and more that isn't looking to buy us much. So now it's morphed into changing processors to do acceleration, while still looking at an old school approach with the control logic, all the while attempting to keep the costs reasonable (not a lot of bells and whistles).
The information you provided appears to confirm what was talked about in the Atari Classics magazine article, where the 6502 is retained along with the addition of the 65816. Actually I'd just like to see a 65816 flying solo with a moderate speed up, and of course have the ability to downshift to 1.79 Mhz full time any time desired. Part of the plan would be to stick with 64K base RAM being shared, although that would be better served with higher speed static RAM. Since the 1088XEL and the soon to be released 1088XLD have fast SRAM already, that will be my initial target platform for any prototyping I'll be conducting. Please keep in mind that this is just a for fun exercise, so there might not be an end product coming out of this from my end, although the intention is to share methodology being applied in the experiments to follow.
I think it would be hilarious to use a 65816 upgrade on a disk drive... Then again, one could have a GUI load from there and use the SALLY in the Atari to still run all of the programs.
With all of the exotic GEOS Wheels upgrades over in C64 land, I'm surprised they haven't done that... run GEOS from an upgraded 1541/1571/1581.

Baby steps here ... let the XM land, "future" is all that's been so far.
I'm quite sure the 8-bitters playing that multi-platform 8-bit racing game online enjoy it.
Besides, who wouldn't want a PlatoTerm port to the 7800/XM? [joking].

2 hours ago, Bruce Tomlin said:The 7800's "laserdisc" port was literally nothing more than a fancy A/V port that also had the ability to replace the main Maria 14.3MHz clock crystal with an external input. From the looks of the schematic, all the genlock magic was probably going to be in the disc player add-on, which would connect to your TV instead of the 7800's RF modulator.
It's more than that. The I/O has translate the joystick movements to correspond with playing the right video off the LaserDisc or CED player. The Amiga and the Atari ST both had a LaserDisc player option to connect such a player via the Parallel port - or was it serial? I forget - in order to play the Dragon's Lair arcade LaserDisc exactly as it played in the arcades.
Until the specs are revealed for the interface as well as whatever program would've been on the corresponding cartridge, it's all assumption. Of course, the 7800 cartridge slot can use actual CPUs and graphics chips in addition to sound chips.

Provide him with links on how to replace the internal clock battery...

At least it truly lived up to the name Double Dragon. As opposed to the NES version which should be referred to as Single Dragon.
The SMS version - especially with a Japanese SMS or a modded American/European model - is very good amongst the 8-bit platforms. I did like the 7800 a lot, except for the audio. The ST and Lynx versions were also good.

On 8/2/2019 at 6:40 PM, DrVenkman said:Except again that the Expansion Interface isn't a full bus interface - it was intended for a single planned peripheral which was never released. But hey, at least it DID have a planned peripheral, unlike the oddball connector stuck off the back of the 5200 and the 800's production test connector stuck off the back of the main board. 😛
The 5200 Expansion Port did have a planned [unreleased] peripheral... a music keyboard.
CPUWiz knows the I/O capabilities of both the 5200 Expansion Port and the 7800 Expansion Port. I forget them off the top of my head.
One would think that a port meant for I/O with a music keyboard [the 5200's port] and a port meant for I/O with a LaserDisc/CED player(s) [the 7800's port] would have enough 2-way bandwidth capabilities to support extra joysticks. The extra 2-controller expansion cables that connected to the Parallel Printer Port on the Amiga and Atari ST come to mind [for Gauntlet II and Leatherneck, and maybe other titles]. If possible, that would be a great way to give 2-port 5200s and the 7800 the ability to support 4 joysticks, especially since both lack the ability of the Atari 8-bit computer line to use devices like the MultiJoy.
Curt has speculated that Joystick Port #2 on the 7800 has enough serial capabilities to support connecting the 7800 into something like a MIDI Maze ring and his theory is that's what Atari Corp would've done if plans to produce a MIDI Maze version of the 7800 had materialized [or maybe it did but the project has been lost to time, like Paperboy]. After all, the unreleased 7800 Keyboard would've plugged into there and offered an SIO Port driven by a proprietary chip and not a PIA.
As for some project on YouTube, I'm assuming it's in reference to the videos of mods to run multiple 7800 games internally with a switch. I seem to recall a video that had Pole Position II running like that. Probably based upon the European BIOS that had Asteroids included.
What would be pretty cool would be to have a board with a 6850 or a 6551 included and then connect a WiFi "modem" to the 7800 so that one 8-bit multi-platform online racing game could be ported to the 7800. I guess a 6850 or 6551 wouldn't be necessary with all of the modern-day solutions available unless wanting to be era-authentic, although WDC still produces 6551 variants. Future XM owners could, of course, add a PIA to the XM and then connect whatever connector SIO Port-based solution is available in Atari 8-bit land to use said WiFi "modem".

Atari Inc probably didn't want people plugging in their old 2600 power supplies into their brand new 7800s. I'm assuming that's why they chose the different design for the 7800's power supply plug.

This is not meant to be critical or taken that way. But do NES home brews sell?
From what I've seen [which is a small-sample fallacy, of course], the EverDrive and all of the emulation systems [whether by Hyperkin or the NES Mini] have the market sewn up.

So what 2600 games are left as of August 2019 that could definitely still use Trak-Ball support?
*The light gun games?
*The Milton-Bradley Cosmic Commander and Flight Commander games?
*Atari Football?
*Crystal Castles due to its way-to-busy kernel thus requiring a total re-write of the game?
*Dave Staugas' in-house 5-Spider Millipede on account of the ROM not being available?
You guys have done excellent work... Impressive...most impressive!

Dedicate it also to the late Ted Dabney. And Al Alcorn. That's the triumvirate that made Atari what it was... without Pong, they would've been another Exidy.

On 8/8/2019 at 12:53 PM, Clint Thompson said:The two scenes that made it for me is where he takes his holographic girlfriend outside in the rain after the upgrade and the holographic Elvis concert scene while they're fighting. They could have cut down on some other things that ended up making the movie much longer than it needed to be but overall I was satisfied with it enough to have seen it 3 times now, as it's rare for me to watch most movies more than once.
The lighting was much more forced or noticeably so I felt, as they tried to stay true by matching the original in that regard but it was almost painful in parts... like why are you trying so hard!
The run-time helps to encapsulate the viewer into that world. To quote Tarantino - who does the same thing - it should be considered a "hang out" film. You're hanging out with the characters in their lives...

But I also believe that the actual market for Atari Lynx LCD games is very small.
I'm looking forward to the first tests.
Cheaper LCD mods is one way of growing interest in the Lynx platform amongst retro enthusiasts.
Hmmm... wasn't Candle working on his own solution before the McWill mods hit the market?

Awesome - does that mean you're in?
Thanks so much for the words of encouragement. I wish I knew someone who knew someone in the inner circle of that show. I don't actually think there's any chance they will even pay attention to me.
Also, I'm still on the fence on which system to do this for (the 7800 or the NES). I already have the engine for the NES (I'd have to convert it for the 7800), and Shawn makes a good point about the NES being the popular system at the time of the 4th season. But on the other hand, I'd rather do a new 7800 game, and if by some small miracle it does get connected to the show in some way it might make the 7800 more popular...34 years later.
So I'm still trying to decide.
Do both... but make the 7800 version better and release it first. It would be cool with either version if it could possess the R.O.B. That would be extra notoriety.
If only there were some Axlon Andromans around in the retro scene...

On 8/6/2019 at 12:08 PM, Greg2600 said:Well the show (which I am a diehard fan of) kind of precedes the NES and 7800. Seasons 1-3 have been set in 1983, 84, 85, when the 2600/INTV/COL were the primary home systems. Season 4 starts filming in October, so Bob you'd have to hurry! At this point, nobody is sure if they will continue beyond S4, which most expect to be set around Halloween again, this time 1986. NES/7800/SMS were a bit more on the radar by then. However, in terms of simple programming, NES might be better simply for musical possibilities, as Stranger Things soundtrack is quite critical to the show. Then again, if you were to really be period-specific, probably should code it on Commodore 64!
Alternate time line where Atari Inc survived and the 7800 was released on time for Christmas 1984. Similar to the alt.universe on Fringe that highlighted the 7800, but with or without Eric Stoltz remaining as Marty McFly in Back to the Future.

So unfortunately the chances of getting anything from him at this point are slim to none.
Those damn anarchist time travelers, trying to erase out-of-place artifacts like the alternate Gyruss from our terrible time line. It's bad enough they took down Atari Inc. by installing their Ray Kassar-bot as CEO. And to add extra insult, they programmed him via a Commodore Plus/4 via DIN plugs in the back of his neck during his daily commutes in his limo to and from Napa.
A fire is also the reason why Dan Kramer is apparently the last Atari Inc'er to have in his possession 3-Base Missile Command for Atari 8-bits. He's still waiting for an offer to finally market it as well as convert it to the 5200 so it can be played with his gloriously designed CX53 Trak-Ball Controller.

The programmer has (or used to have?) the other version of Gyruss as well as unreleased Atari stuff but I suppose people already asked him several times before.
Patiently waiting. Just like for the programmer in the UK who wrote Paperboy for the 7800 and supposedly has it on an ST disc up in his attic.

Well, that's a load of Fake News...

When I saw the Roklan bit, I was hoping their version of Gyruss for the 5200/8-Bit had been acquired... one day...

I may contact B&C in case they happen to have any documentation for installing the board. I'm a little concerned that no one will respond (it looks like pages have been down in B&C's store for a while).
B&C operates primarily on eBay under the account "MyAtari". You could try contacting him through there...

2049 is a fantastic film. And the producers insisted upon having the Atari logo appear in the film from the get-go. They also banned logos from any company that didn't exist back in 1982 when the original film was made. Their attitude was that in the Blade Runner universe, Atari in the year 2049 is even bigger than Apple in ours [in 2017 when the film came out].
