PS-1 monitor on AT clone?
| 
Nov 23 13:13 UTC 1994 |
I have what I'm pretty sure is a PS-1 monitor. It has two video (?) cables
coming out of the back. One is a standard 15 pin mini D type VGA connector
and the other is a standard size 15 pin female D connector. When I plug
the mini 15 pin into my computer's VGA card, it works fine but I have no
color or gray-scale. Is this a B&W monitor (It's power input is rated at
115 vac @ 2 A. I bit high for mono.) or color? What is the second cable
for? I noticed it gets plugged into the back of PS-1 machines.

Good point! If memory serves, all the pins are there. Anyone know what the
normal size 15 pin D is for?

<<glad I sti ahve this book open>>
the PS/2, 15-pin video connector (listed here as a DB-15, so it's
the big sized one) has two separate pin configurations. Thisis
the computer's connector -
pin number monochrome color
1 no pin red
2 monochrome green
3 no pin blue
4 no pin no pin
5 self test self test
6 red return (analog ground)
7 mono return green return " "
8 no pin blue return " "
9 no pin no pin
10 digital ground digital ground
11 no pin digital ground
12 digital grounno pin
13 H sync H sync
14 V sync V sync
See if that helps any.

Great! Thank you for that information! I take it that pin 12 is digital
ground.
On a slightly different tack, I noticed that there is a earphone jack on
the monitor. I wonder where the signal for that comes from? Also, on the
PS-1 I looked at on display at Play It Again Computer, both cables seemed
to be plugged into the back of the CPU. Odd, since they both seem to have
the same signals on them.

#3 was horrid formatting - sorry, using the wrong machine
right now ... no vi .
pin 12 in the color column, should be no pin . in the
monochrome column, it's digital ground .

It seems to be a mono display. I also belive that that the pin numbers
listed in item 3 are those for the mini 15-DB too. I guess I'm still
confused. Are the 2 cables redundent? (No!)

I'm considering that they are redundant (to suit two different
driver cards easily) but i only have pinouts for the one
style of plug.
