"Posh" is a great way to put it! The 8530 is a fantastic chip.
That's a pretty serious board. There's also a '286 on there, DMA and
interrupt support, a bunch of memory...whatever it did, it needed some
horsepower! My guess is a high-speed sync port with onboard protocol
handling.

it must be 1995 or later. The AMD85C30 is a posh USART so I suspect it was
for high speed sync/async communications. I wonder if the small connector is
X.21 interface...

Subject: Unidentified Emulex card from 1991
Hi.
I got unidentified Emulex card from, probably from 1991.
It is 16-bit ISA, it has two connectors male DB-25 and male
DE-15F (like
on VGA cards, but male).
It is probably multi-port card, but I'm not sure.
Here detailed photos:

Does anybody here know what this is and whether it's possible to get
manuals? Programming manuals?
