S-100 Polymorphic Systems card questions

[Saquinn624 at aol.com]

I have a S-100 based system that seems to mostly run, but I have some 
questions on the video card.
It is a Polymorphic Systems card, but looks different from all the examples I 
could find on the internet

Markings are: Polymorphic Systems (c) 1976 I.P.C VIDEO  rev 0.0, with most 
chips aligned vertically

The keyboard? port is a 14 pin DIP socket in the upper R.H. corner, next to a 
8212 I/O chip.
Between this and the VIDEO marking, there are some pads with heat damage that 
have the symbol for Zener diode across one of them. I have no idea what the 
component specs are for these pads.

Also, 2 questions: does anyone have the DIP switch settings table for this 
card? 7 switches, currently set at 1 1 1 1 0 0 0

and (2) the 8212 interface makes me think that the keyboard is some sort of 
parallel interface, but the computer came with a DIP header connected to 3 
wires

(bonus question: this card has some jumper wires and a resistor soldered on 
the trace side of the PCB, is this official, or is this a hack? the joints look 
sort of "hacky" the resistor goes between +Vcc and pin 20 of the 6571AL, the 
jumpers are between some of the 74XXX gates on the L.H. side of the card 
[where the 7805 V.R. is])

found it at my church garage sale several years ago, so I can't "ask the 
owner"
