I picked up an Atari 800 off of eBay which didn't show any pictures of the included cards. I was originally hoping that it included the 10K ROM as well as fully loaded with the standard (3) 16K boards for a total of 48K - but figured it would be empty since the seller didn't show any photos. I was surprised at what I found inside and now I'm curious about the unique combination of memory cards along with the 3Bit Full-View 80 card. There are photos below indicating the configuration as it was shipped; Slot-1 with the 10K ROM, Slot-2 with a 32K Mosaic RAM board, Slot-3 with a 64K Mosaic RAM board, and Slot-4 with the 3Bit Full-View 80 card. There are also two small ribbon cables coming up from the main board inside the 800 which connect to the 64K Mosaic board.
I don't have a monitor that would possibly work with the Full-View 80 card, so I'm unable to test if the system works with the configuration of cards as it was delivered. In fact, the only way I can get the system to come up is with the 10K ROM card installed in Slot-1 along with the single 32K Mosaic card directly behind it in Slot-2 - however, with the BASIC cartridge in the left cartridge port, the 'PRINT FRE(0)' command only shows about 13K of free memory available. All of the game cartridges I have function normally with this configuration.
I picked up an SDrive-MAX, but so far have not been able to get it to work - I think it may be due to this unique combination of memory cards. As a first step into the retro Atari world, I'm just looking to use the physical Atari 800 with the SDrive-Max to play the vintage games I remember playing as a kid.
Any thoughts on the best way to proceed - possibly just purchase the (3) 16K memory cards and try the system with the standard 48K? I think it's worth trying, but I'm a little concerned with the cabling running up from the main board and the customized modifications that may have been done to run the 96K configuration.
