A lot of the emulation cards are missing software - especially those that are not IBM, AST, or Emerald. And nearly all are missing the DB-15 to dual TwinAx dongle. I recently sent a NiB AST 5251 model 11 and 12 emulation card manuals and disk pack to bitsavers.org for archiving - including the 8" floppies for file transfer support on S/36 and S/38.

I'm specifically doing it for both conservation of the technical information and the technical challenge. It would be nice to have a fully open and documented twinax interface project that covers both the hardware and software side of things. I appreciate the market twindata.com services and not trying to undercut it. You get what you pay for in software maturity and technical support. But it would be nice to have alternatives.

Personally I don't know why you would go through all this effort. It's
pretty easy to pick up some 5250 ISA and PCI cards off eBay, and connect to
an older system that way. I still have a few terminals at home that I use,
but I also have a 5250 PCMCIA card in my IBM T60 Thinkpad that I use the
most. I was able to grab 4 of these off eBay about 10 years ago.

So besides the technical hey I did this kinda thing, what are you trying to
accomplish here?
