Lot of 4 boards for Apple ii vintage series computers. To the best of my knowledge, these boards are as follows:
Apple IEEE-488 Interface from 1980
Microsoft Z-80 Interface from 1980
Apple Interface 1981
Unknown (JTM?) Asynchronous Serial Interface Model 7710-A
Please look at the photos or ask questions for more details about them if you need to know the assembly or part numbers that are printed on them. The boards are all clean and came from the same owner, but are untested. There were a couple other boards from this same set that were sold separately and tested and they both worked. Returns accepted on any non-working ones.
