Hi, I have a Mountain Computer Inc. A/D+D/A card (PWA 05-00150-01 C).
It originally came with documentation and software when it was released in 1981. Those have been lost over time. I asking to see if anyone has the documentation and software for sale and/or a link where I can find this. I have done some Googling but have had no luck so far.
