I believe this version is the first of the RFI motherboards. This motherboard has been tested to make sure all the ram is good, as well as the ROMs. It boots properly from a drive controller installed in slots 1-7, and works properly with a memory expansion card/language card (not included) in slot 0. The joystick port was tested and works properly. The video output looks good, and so do the color bars. The date code is 8110 (10th week of 1981). The motherboard has a ...lower case chip. This board has been fully cleaned and tested, and works great. If you don't want the lower case chip, let me know and I will replace it with an original Apple II+ character generator ROM.
This board does have 24 metal covered ram chips from Texas Instruments, which are more rare than the plastic DIP ram chips.
Please note that I test all my motherboards the same way, using the Apple II Dealer Diagnostics as well as other programs. The motherboard photos above are the actual board, but the 3 testing photos may be from a different board, but all boards pass all the tests or I don't sell them unless they can be repaired and re-tested.
Take a look at all the photos, and if you have any questions, please ask.
