[comp.sys.amiga] Princeton Ultrasync

gregb15@pro-charlotte.cts.com (Greg Beckham) (07/01/88)

 Has anyone had any experiences with a Princeton UltraSync? Could some one
please send me some stats(ie. max resolution, scan, etc.) via e-mail and I
will post a follow up. The reason I am asking is with the introduction of
newer graphics chip, which need higher resolution and scans, I don't want to
have to keep switching monitors. 

                T.H.A.N.K.S,

PS- Also, could I have some info on the following monitors:
Mitsubishi DiamondScan
NEC MultiSync
NEC MultiSync Plus
NEC MultiSync II
NEC MultiSync XL
Thomson UltraScan

I am having some difficulty hooking up a new Princeton Ultrasync to an
Amiga 500 so I was wondering if anyone out there knows the proper way
to hook it up. The cable I got from Redmond didn't work at all, the
monitor wouldn't sync at all. That cable used the composite sync but
had the monitor's horizontal sync connected to ground. I made another
cable that did not ground the monitor's horizontal sync (left it
unconnected).  This new cable works for about 10 minutes and then the
monitor starts to lose sync again (starting at the bottom of the
screen).

Now one or more of the following must be true:

- The amiga is not working (the color/rgb out has never been tried on
this computer and unfortunately I dont have other computers/monitors
to try a swap comparison)

- the cable is still wrong

- the monitor has some strange thermal problem

Have to cut this short, the sync is going again,
Any ideas on what is going wrong here? AND
in particular - How should the cable be wired????

I know of one Princeton in use, and that is driven HD and VD through
buffers.

The Ultrasync I have works fine, with no buffering needed on the sync
lines. I now use a cable that I got from Redmond cable, but I wired
one up myself (using a hacked 25 pin connector) when I first got the monitor.
This is on an Amiga 2000, though. I can dig up my original wiring list
if you'd like.
