ianoid Posted July 14, 2020 Share Posted July 14, 2020 Here are some Atari diagnostic and other dumps. I didn't photograph all of them. The Expandovision cart I tried multiple dumps just in case. It would not start with Altierra and I think it did the same on real hardware. Perhaps it's waiting for a handshake from the Expandovision device. It has no label. In fact, I can't be certain what exactly it is. The unknown board has 4 eproms. I believe I couldn't get it working on real hardware (tested on an 800xl only). I included multiple dumps, I was trying everything I could. Enjoy. @Rom Hunter A8 - 810 disc field exerciser 16K.bin A8 - Atari 1200 Super Salt Rev A.02.bin A8 - CPS Super Salt Master Rev.

_The Doctor__ Posted July 15, 2020 Share Posted July 15, 2020 when using carts with multiple roms/proms it's best to name them buy position as well as what they are... if you don't know what they are... then include whatever details you can from the labels and what you discovered... still include the position on the cart or card. Might run on and 800 or a 130XE Quote Link to comment Share on other sites More sharing options...
re-atari Posted July 15, 2020 Share Posted July 15, 2020 There's a (rare) 2763 eprom on the PCB, should be compatible with a 2764. The partnrs. on the other eproms are not clearly readable, though. Which file(s) is/are the dumps of these 4 eproms? Try to draw a schematic of this cartridge, interesting to see what it's supposed to do. re-atari Quote Link to comment Share on other sites More sharing options...
www.atarimania.com Posted July 15, 2020 Share Posted July 15, 2020 The Expando-Vision system lets you create subliminal messages using the hardware device which comes with the first cartridge: http://www.atarimania.com/game-atari-400-800-xl-xe-expando-vision-weight-control-exercise_1909.html The cartridges all boot straight away, the hardware device is only required when you create the messages. There are eight programs but only four have been dumped so it would be great if this turns out to be a title that is missing. 1 Quote Link to comment Share on other sites More sharing options...
ClausB Posted July 15, 2020 Share Posted July 15, 2020 On that tall, bare cart I can make out 2764 on the second EPROM down. So how do you fit 4 x 8K into Atari's 16K cart space? There's no bank switch hardware visible. Is there a switch on the other side? Quote Link to comment Share on other sites More sharing options...
ClausB Posted July 16, 2020 Share Posted July 16, 2020 How? You don't. It's not an Atari cart. The EPROM Vcc line goes to the rightmost edge contact, not correct for Atari carts. 1 Quote Link to comment Share on other sites More sharing options...
Tempest Posted July 16, 2020 Share Posted July 16, 2020 Could it be a Colecovision cart? 1 Quote Link to comment Share on other sites More sharing options...

ClausB Posted July 16, 2020 Share Posted July 16, 2020 (edited) Yes, the Vcc line matches that, and so do the 5 visible data lines. And Coleco uses four 8K select lines as well. Edited July 16, 2020 by ClausB Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted July 16, 2020 Share Posted July 16, 2020 If you look at the unknowns they are just banks of EF and FF's Quote Link to comment Share on other sites More sharing options...
www.atarimania.com Posted July 16, 2020 Share Posted July 16, 2020 (edited) OK, the Expando-Vision cartridge is this one: http://www.atarimania.com/game-atari-400-800-xl-xe-expando-vision-control-smoking-calm-nerves_1906.html It would be interesting to compare the two dumps to check whether the versions are exactly the same or see what prevents ianoid's ROM from booting.

Both images of Expando-Vision contain some identical code and many different text strings. The cart contains only 4KB of data which are mirrored to the second half. @ianoid's 16KB dump is 8 KB of $FF followed by the 2*4 KB of data. And it is a bad dump. It seems that the $200 address line is always high. Edited July 16, 2020 by DjayBee Quote Link to comment Share on other sites More sharing options...
ianoid Posted July 19, 2020 Author Share Posted July 19, 2020 It sounds like the Expandovision cart has been dumped. Unless it is really needed, I'll hold off on more attempts to dump the Expando cart. So I guess I should try that 4 ROM board on Colecovision. I didn't realize the boards had the same size card edge.
