Do they safely fit without pressure, the XE boxes sealed with cellophane? If they don't does anyone else have any leads on some that do? Finally looking to properly display and protect my collection so I would appreciate any help finding box protectors for all sizes of Atari 8-bit Home Computer boxed Cartridges.

That is the only 2500 I have ever seen a picture of and the auction says it is working! How much do you think it will go for?

I'd like two of each board.

He's on here...http://atariage.com/forums/topic/280437-big-pick-up-from-former-software-developer-hardware/

I'll take two as I said previously.

How much does it cost for parts to build one?

I see on the AtariOnline page that AtraX 7 isn't listed. Does anyone have a backup of it? Also can you use AtariMax USB Programmer to read AtraX cartridges? If you can, what settings do you use? Thanks

I just updated my want list and deleted some of the carts I picked up in the years since I first posted it. Still would like ans Espial cartridge or any of the others on my list. Still dreaming about a 1450XLD and 815 if anyone would part with theirs. I would be interested in the 1200 Proto/Pilot or 1400XL.

Do you have the list of hardware you are using? Do you have the floppy diskette someone mentioned for it?

Thanks for the updates. I'd really love to check it out; it is such a great missing link. Please let me know if you ever decide to part with it and the BASIC cartridge.

Raise the dead. I will raise my buy from 2 to 4 if this brings the project to fruition and Candle can produce them.

Oh well, if there are any errors in my previous post, it won't let me correct them now. It looks like your BASIC cartridge should work in a production 800 if you align the left most pad with the third slot pins from the left, is that correct? I think that was what Rybags was referring to as downward compatible in post #38.

Thanks for the schematic. It is hard to follow the pin order in your schematic, I will post it bellow to make it clearer. I am trying to compare it with the production version. If you could label the signals on your pictures of the front and back of the Basic cartridge you have it would be easier to compare. The production has the pin-outs (pin order of signals) listed/labeled on the port and cartridge PCB A thru S and 1 thru 15. Please check the following to see if I have it correct... especially the chip select with address range ...

What is the left cartridge/slot pin-out.
