This is not a DEC hack nor standard production. I'd suspect someone in
the field needed a fifo buffered serial and did it this way for themselves.
It could be a CSS (computer special systems, DEC) hack as they did oddball
things for big customers (tempest and the like) but I'd never seens much
in the way of hacked Qbus oddities like that one.

Thanks to the people who have responded. There is no
suffix to the board
number. M8189, that's it. I've looked really closely at the soldering of the
UART socket. It has the same flow as the rest of the components, so I still
think it was manufactured this way. I powered it up tonight and determined
that the daughter card is the console port. I connected a terminal and it
works as you would expect. The firmware seems to be standard 11/23+ 1.0
firmware. I think I'll just by a 6402 UART and replace the daughter card.
Thanks again,
Bill
