This auction includes an Atari Falcon NTSC board that I was going to install in a PC case, plus a CT63 accelerator, and Wizztronics 16mb memory expansion. The Falcon motherboard developed problems early in its life and I had it shipped out to Rodolphe Czuba, creator of the CT63. He repaired the board and tested it, so it's assured to work. Due to the age of the machine, of course, I can't guarantee it, but it shipped to me a year or two ago as a working unit and has not been powered on since. If you need more info about this board, you can contact Czuba directly after the auction and he can verify the repairs and upgrade testing. I also still have the case if you are interested, but what's in this auction is the board, accelerator, and memory.
