[comp.sys.apple2] Color Monitor

ckoprows@ub.d.umn.edu (Chris Koprowski) (05/06/91)

I am looking to get a color monitor for the GS and was wondering what are som
good monitors to get, I saw aome post before about the Magnavox and was just
wonderin how good they are and I also need model numbers.

The Commodore 1080 or 1084 are passable monitors, and cheap. You need an
adapter cable to use with a GS though.

I am currently researching the various options available for //gs
owners. So far, I've called 8 or 9 companies and asked for info
to be sent on any Analog RGB monitors that they make. As I 
write this, two packages (from NEC & Goldstar) that I got
today are waiting to be opened.

I still am awaiting a response to my inquiry here on csa2 about

uusing Mac monitors. If I find that they can be used, I'll be
expanding my research.

	Anyway, I was in the monitor search a while ago.  I finally
just got an Apple RGB (standard for gs), but this is what I found.

	VGA monitors won't work, unless they are multi-scanning.  VGA
monitors are analog RGB, but they don't scan at the same frequency.
The multi-scanning monitors are pretty nice, and they provide for
future expansion, because they are usually both TTL and Analog RGB.
The screens are also usually a bit larger, etc.  You need a patch
cable though, because you have to go from a D-9 connector to a d-15..
it's an easy cable to do...

	The Commodore monitors will work, the ones for the Amiga, I
believe the 1084...  but I decided against it, because I the Apple one
was the same price.  The Amiga monitors also allow for sound to go
through it.  I'm not sure what the deal is with the cable.

	There is also the Magnavox monitor, but I haven't played with
one much.

>uusing Mac monitors. If I find that they can be used, I'll be
>expanding my research.

	I assume the question is whether you can use Macintosh
monitors.  I tried this over the holidays.  It uses the same
connectors and everything, but the one I had wasn't compatible, I
imagine it had to do with the scanning frequency.  I don't remember
the model number or anything (it wasn't mine), but this one was a real
Apple Mac RGB, and it didn't work.

Hope that helps.

	Jeez.. The same price??  I've always heard from Amiga-owning people
that the monitor was like $250-$300, vs. the what $450 list price of the Apple 
one? (List price meaning that's about what you're gonna pay as it seems 
you don't find discounts on Apple name stuff as much as you do on other brands)

	Whatever you say.  I bought my Apple RGB for $299... which is
ABOUT the same price as the Commodore monitor.

Do you know anyone with an adapter cable for the GS?  I didn't see a composite
sync pin on the 1080 or 1084.  Seems you know something I don't know... care to
enlighten me?

Magnavox 1CM135 is a good monitor to get.  I got mine from Lyco for under $270
including second day shipping and handling.  The 14" screen is nice for small
fonts like the earlier fonts on AGATE, which you can actually read on this
monitor.  It has vertical and hortizontal adjust to center the screen and has
inputs for video in to connect to your VCR, and include stereo speakers.  It
has zillions of controls to fine adjust the screen just to your liking... like
vertical horizontal size.  You do have to get a cable, which you can make, or
buy from Quality Computers in A+/Incider.  I can give you the pin outs for the
two, so it'll work correctly.

I had inital problems when I used the pin out of the GS RGB and match them with
the Mags.  It seems there are two types of ground on the GS pin out.  One is
GND, they other two which are label GND are actually -12V, I had them all
connect together and it did some pretty scarey thing with the GS, making it
turn on and off continuously.  I finally disconnected the -12V GND and used the
correct ground (0V) GND on the GS to the Mag.  It's probable better to buy the
pre-made one because you won't be saving much money and you also need a mold
finish for the DB-15 pin on the GS.  The metal hoods on those do-it-yourself
ones you get at Radio Shack get in the way and won't let you plug it into the
GS.

The 108x-s Commodore series has a connector for every model in Commodore's
line, composite RCA for the C64 series, Analog RGB for the Amiga and TTL RGB
for the PC series. GS owners want the Amiga port.

The pin conversions are as follows

Commodore DB 23         pin     Apple GS DB 15
                        3               pin 2
                        4               5
                        5               9
                        10              3
                        15              1
                        16              6
                        17              13

I take no responsibility if this doesn't work or causes damage to your machine
or monitor, however this cable did work with my ROM01 GS and Commodore 1084S
monitor prior to trading up to an Apple RGB monitor.

I still have the cable, but the postal charges would more than the cost to
make one yourself.

Do you feel enlightened?  :)

ANY analog monitor with a 7Khz or HIGHER refresh rate and has COMPOSITE sync
support WILL work with the GS.  Macs and VGA cards use seperate horizontal and
vertical syncs and some even support both types of sync signals (composite and
seperate).

Multi-sync also usually have composite and vert&hort sync pins, which is why
they will work, and there are VGA monitors out there that do support and work
on the GS.  It's just finding them without buying the monitors that's the
problem.

Don't bother with the 1084/S.  They only have support for vert/hort sync.  This
monitor would be adequate... 15Khz refresh rate, analog RGB, but without
composite sync support it's of little use to the GS.

WRONG. Composite vs. seperate sync is workable. Mismatched scanning rates
are not.

Multi-sync monitors work because they support the NTSC scanning rate (which
is what CGA and Apple // video use), NOT because of the sync format.

Wrong again. I've personally seen a 1084 running off a GS quite happily. Some
monitors (the 1084 is one of them) will accept composite sync at both their
horizontal and vertical sync inputs, with a bit of resistance in between to
keep the two from confusing each other.

     To go along with the monitor questions we've seen here lately, does
anyone know if the Magnavox CM8764 can be used with a GS?  Is it the same
as a CM135?  I would really like to know, because all my GS work has been
vicarious for the last fifteen months, due to monitor death and inability
to purchase a new one.  I have a chance to acquire a CM8764 very cheaply,
though, and I'll jump at it if it will work with the GS.  If it can, what
sort of cabling does it need?  I can build my own if anybody can tell me
what needs to be connected to what, but I'd rather just buy one, if it's
possible.  Thanks for any info!
