There are more PEB boards out there than you might imagine, although a lot of them are difficult to find now. There is a SASI controller (the Myarc personality card, very rare); an MFM hard disk controller (The Myarc HFDC, relatively hard to find); an IDE controller (Nouspikel IDE, hard to find at the moment, but I am busy slowly reimagining it with through hole components); two different SCSI controllers (one from WHT and one from SNUG, both somewhat hard to find). There is a handful of double density disk controller cards (from CorComp, Myarc, Atronic, SNUG, and even TI), lots of memory cards (including a 1MB SAMS card that is still available--or better said, it will be as soon as I get my next batch of boards in), and all kinds of really odd but useful cards, like the MBP Clock board that also has analog I/O lines; the IEE-488 card, the aforementioned speech board for the PEB (there are actually two choices here, as the CorComp Triple Tech board will do this too); and all kinds of RAM Disk boards.
Mine is happy with a plain gold band. . .at one point while we were dating I made the mistake of giving her a ring with some diamonds in it. She promptly lost it by hiding it away in her parents' apartment and never found it again. It may still be there, 20 years later (and her parents moved out of that place long ago). I don't think she ever actually got a chance to wear it. . .and the gold band we bought when we got engaged is the one ring she is almost always wearing. It is practical and nice--and because the women of her family have thick fingers, we can switch rings and it doesn't matter, as they are both the same size.
