A1-A6 board have been sold to a buyer in Brazil.
The only logic bard I have left is the 05372-6008 (A8 I think).
I still have cosmetic parts like the the front panel top bottom and sides. I
have all the sheet metal internal stuff and all the power supply boards and
the power transformer. I also have 2 54002A pods.
