The first PS/2 cards look like Token Ring nics. They probably have a blue 16/4 sticker on the faceplate. The big EISA card is a remote access card, the port on the back is a modem. You dial into it and it gives you a remote console, and you can power cycle the machine, etc. I don't know what the 2 MCA cards with RAM on them do. -J On Mon, Oct 31, 2016 at 9:12 PM, william degnan via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:

Among other items, I picked up some of these PC-bus boards. Some of them are IBM brand, I know there's some PS/2 interests. A passive ISA backplane too. Also HP brand, and some non-PC bus NEC. The Iomega brand boards, are likely interfaces for Iomega old removable drives. Contact me if you know something about these cards, and have an interest. I'll be at the December event. - Herb
