Those bars are from the $A000-$A7FF block of $FF's which happen to be where 2 Display Lists are pointing to :)

Did you Swap the LOW and HIGH ROMs yet?

 

Your still getting that Display List code in your 16k dumps :(

Try just using the cart dumper ATR and save the 16k directly to that and post the ATR,  that way we can see what's happening...

 

 

I didn't swap them — I'd hate to break pins.

 

I DID just use the cart dumper ATR and save directly to that ATR. Then I pulled the file off using Atari800MacX.

There doesn't appear to be any corrosion on the pins,  so removing them gently should be okay.

 

Which version of the Cart Dumper are you using?

D501 00 - 1999. Nir told me to use that one.

I had let this project drop.

 

Here we are almost exactly a year later.  I have now acquired an E.R.I.C. laserdisc, and have the hardware setup to control it from the Atari. I searched for info on the software to control it, and found this thread that I had forgotten about. 

 

So, if I understand this, even with the "corrected" cart we're still missing some data. I believe I need to swap the ROMs, and put them in another cart that has two 2732's re-dump. Is that right?

 

Can someone recommend a common cart that meets that specification?

 

thanks

Do you have the list of hardware you are using?

Do you have the floppy diskette someone mentioned for it?

My hardware: 850 interface connected to a Pioneer LD-V2200 laserdisc player (there are a few Pioneers models that will work) via a custom serial cable. I have figured out how to control the laserdisc player via BASIC. I know Atari's kiosk setup also used a Pioneer laserdisc player, but don't know for sure if it was the same configuration using the 850. So I don't know if the cart will end up running the disc properly, even if I had the floppy disk. But it's worth dumping the cart anyway. Perhaps we can reverse engineer it to figure out what it expects on the floppy.

 

Even if I can't get it to work using the cart, it should be trivial to recreate the E.R.I.C. kiosk experience using a BASIC program that I'll write.

Scratch that,  those are 2764's in those.  I've seen 2732's in some recently,  will check....

Kevin, I saw you were active in a recent facebook thread where someone else also seems to have a cart PCB with these EPROMS.

 

I seem to gather from this thread there is some debate as to whether your PCB board the EPROMS are mounted in is fully functioning/compatible with the chips... Since these are 2732 EPROM's they're easier to dump since its a common/better supported type. I have the TL866 burner, its as cheap as $45 free shipping from china/ebay with no adapters and it supports this chip. (eg https://www.ebay.com/itm/180926954184) I don't think there's mac software for it though. I have used this burner to read/write 2732's for my 1050's ie for US Doubler.

 

I'll make the same offer I did on the FB thread to the other guy, if you want to mail it to me (I'm in Canada, but they're small and should still fit in a letter-mail type envelope, maybe ditch the PCB and stick them in antistatic foam if you have any ) I would dump the 2 chips with my hardware and then mail them back, with extra copies burned if you like...

Thanks for the offer, but I'm not going to trust a rare cart to the perils of international shipping. It should be possible to dump it myself, or at least more local to me.

I spent the weekend writing a BASIC program called E.R.I.C. POP #1 player. It does what the E.R.I.C. cart does: play the interactive POP videodisc from an Atari computer. it probably doesn't work EXACTLY like the E.R.I.C. cart, but unlike the cart (which hasn't been dumped yet) my BASIC version can be easily modified.

 

You probably can't run this because it requires a Pionner LD-V4400 or compatible laserdisc player, E.R.I.C. POP #1 laserdisc, and Atari 850.

 

If you have all that, the software is attached.

 

Attached File  ERIC.atr   90.02KB   20 downloads

Attached File  ERICPOP.TXT   5.51KB   21 downloads

 

I may make a video of it in action. I will definitely be showing this off at the some vintage computer show eventually.

 

My next thing will be to try to control a DVD player via serial. If that works with proper exact frame control, I should be able to copy the E.R.I.C. laserdisc to DVD then modify my program to run from DVD. Industrial DVD players with serial control are a lot easier to find than E.R.I.C. laserdiscs.

Ooh, it works. It works really well. With barely any changes to my program, it can now play the E.R.I.C. demo from DVD, using a Pioneer DVD-V8000 DVD player connected to an 850 interface. This model of DVD player is easier to acquire and more reliable than a Laserdisc player, and the DVDs can be easily copied, unlike laserdiscs.  Accessing data on the DVD is faster than the laserdisc, too.

I will make the E.R.I.C. video available on DVD for $10+cost of shipping to anyone who proves to me already have the DVD-V8000 player.

The program as written assumes the Pioneer serial protocol. (eg FR12345SE to search to a particular frame number.) I don't know if other brands follow the same protocol, but doubt it.

Here is a video about Atari's Cyan Engineering. Near the beginning they talk about why they made this video disk. Though they do not call it ERIC.

 

ERIC POP number #2 (XL version) here, just the video not the disk.

 

They show what looks like a 1200XL on the desk, but video #2 shows equipment choices 600XL, 800XL, 1400XL, 1450XLD. So are they really using a 1400XL in the demo?

Nice.

 

I'd like to make a version of the ERIC POP Player that works with #2, but I'm going to wait to get my hands on the laserdisc so I can digitize it myself, or at least for someone to make a higher-quality digitized version.
