Misc cart dumps

Recommended Posts

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

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

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.

The Expando-Vision system lets you create subliminal messages using the hardware device which comes with the first cartridge:

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.

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?

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.

Could it be a Colecovision cart?

That would be my guess as well.

Yes, the Vcc line matches that, and so do the 5 visible data lines. And Coleco uses four 8K select lines as well.

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.

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.
