I have recently acquired a DEC GiGi terminal and a Barco GD-33 RGB
monitor from a friend of mine who is moving away. The GiGi is kind
of fun to play with, but what I really want to do is connect the
Barco monitor to my Amiga.
Will it work? The specifications for the monitor (from the manual)
are:
525 lines 60 Hz interlaced or non-interlaced
red: non-composite 0.7 Vpp +- 6 db positive
green: non-composite (EXT. sync) 0.7 Vpp +- 6 db positive
composite (INT. sync) 1.0 Vpp +- 6 db positive
blue: non-composite 0.7 Vpp +- 6db positive
sync: (EXT sync) negative 4 Vpp +- 6db
EXTERNAL or INTERNAL sync mode selectable (switch).
frequency response: 15 kHz to 7MHz + 1 db/-3 db gradual roll-off.
line scanning: horizontal retrace time < 10 uS.
vertical scanning: vertical retrace time < 900 uS.
picture tube: high resolution, precision in-line shadow mask,
auto-convergent CRT tube with black matrix. Pitch = 0.31 mm.
This sounds like a nice monitor (0.31 mm dot pitch!) if I could make
it work. It uses BNC-type connectors on its inputs, so I would have
to put together a cable. Does anybody know where I can find cables
and/or parts to build one? Also, if this monitor will work, does
anybody know if it will accept an analog signal? The GiGi only
outputs 8 colors, which makes me worry that this may be a TTL RGB
monitor (which would be most distressing). I know next to nothing
about video monitors, so some advice from a video guru would be most
appreciated.

Before I got my 1084, I brought my A2000 to UNR to see if the BRC monitors on the DEC GIGI terminals would work. All I had to do was make a cable for R,G,B and SYNC, connect it to the BRC and flip a switch on the back (of the BRC) that allowed for external sync. I'm at home now so I don't know the model# on the monitor, but I'd be happy to do so... just say the magic word! It worked fine. The display was a tad smaller (and more rectangular I think). It wasn't stated in the above, but I used the ANALOG R-G-B output of AMI. If you need details of the cable... just say the magic word! ...is there an echo in here? mark iverson marki@tahoe.unr.edu

please substitute Barco for BNC in my previous posting. mark iverson DUNCE@where.the.fakauii <:-)
