As there is someone asking why this doesn't show up in the search, below is the link to the listing. Keep selling the remaining stock. These are made with 70s~80s old process steps with special ordered materials. The boards are chosen by some museums for their displays. I currently have no plan to reorder new batch for either NTI, non-NTI or cassette interface as the fabs quoted much higher on new order and apply mininum quantity as what I asked them to do is just non-standard.
