Fantastic video, many many thanks for sharing your experiences, and congratulations on such an impressive quality video. I have a DEC 3000/600 AXP with 24 bit colour graphics card, but no additional cards in it. It was bought for me when I was doing a PhD so I had the amazing opportunity to unbox and set it up and then used it for a few years, before rescuing it many many years later.
