I have a couple of these as well. The one to have way back when was made by AST. It had 4 16550 UARTS and could run them all at whatever speed you wanted.
There was even a public domain program/device driver for it, for UNIX on x86 called FAS (Final Async Solution) that worked very well. I still have a copy of it if anyone is running real serial on period hardware and SVR2/3 and maybe others. I ran these boards for a couple years on my public access UNIX system.
