Wanted working HP-67 board

[YoungerThanThat]

In fact I have Teenix board in my HP-67. It did not work the first time and the calculator did a very lengthy (timewise) trip to Australia and back to be updated and it still has issues. I am going to try to do an update myself when I get an FTDI board but I thought I could also explore the simpler option of finding an original board that is still functional. My HP-67 is truly cursed. It has done exactly 5 trips for various repairs and it still does not work.
