| Mac 12" RGB Monitor 640x480 hack |
Posted by: techknight on 2016-05-31 16:48:58
There was a website that goes through modding the M1296/M1299 12" RGB LC topper to run at 640x480.
Ill be damned if I still have the link.
out of curiosity, does anyone have it bookmarked?

I bet it's almost the same as modding a CC

Oh thank you, your a savior!
You get a cookie of the day. lol
Once I get my 12" RGB monitor rebuilt, I am going to do this mod eventually. I have a 12" RGB that came from uniserver that had a vertical issue I did a youtube video on, turns out a cluster of capacitors near the yoke connector, and horizontal drive transistor spilled its guts.
So a recap is in order, plus a flyback changeout. Then were good 🙂

I'll give you TWO cookies if you can do it all in one sitting AND video tape the whole thing. And then take a shot of moonshine at the very end and slam the empty glass on your bench, shouting HELLL YEAHHHHH

Looking forward to seeing how this goes, techknight 🙂

Looks like the hacker above had a second attempt at doing this mod in a slightly different way:
http://mobley.jp/e05mod05.html
As I said before, my VGA adapter was not very strong, and my children broke it by rough treatment. So I decided to modify monitor sense of the original cable connecter itself so that it would be permanently wired for VGA mode. |

I have to change the cable out in mine anyway, it has an intermittent color when you twist the wire, so I will fix that then.
Before I can do the hack though, I got to finish refurbing the analog board and getting it going again properly.

Any news on whether or not the IIGS monitor and LC Topper use the same flyback? I did go ahead and buy that flyback on eBay to repair mine.
I do have a IIGS monitor now but don't feel like cracking it open...

The flyback I ordered looks 100% identical to the one in my Mac RGB monitor, But I havent had a chance to swap it out just yet.

OK, a few questions here...
1. Is it possible to swap guts from monitor to monitor without desoldering the flyback?
2. Does this monitor self-discharge when you unplug it?
3. Anyone have a list of caps for these monitors?
|
Posted by: techknight on 2016-06-25 17:36:03
1. Yea, but you have to unhook the anode cap from the CRT
2. Yes with time.
3. Working on it, eventually...

OK--I think I'm good on the first two. I'm thinking of doing a quick fix with my LC monitors until the original part can be repaired with both caps and a new flyback.
One has its anode cap removed already, the other hasn't been powered up since 2013 so I think we're extra safe there 🙂
I just want my LC to run again 🙂 I have an extra LC board and a re-capped power supply that I won't need for a few months that I can use as stopgaps until everything is refurbished.
EDIT: Once I get the board back, do you think maybe 3 days is sufficient to let the monitor discharge? I know I could use the discharge procedure but I trust the monitor discharging itself more than I trust myself doing that. (I honestly never discharge my Classics and SEs and have removed CRTs from them after having powered them down just a few minutes earlier).

usually the bleeder resistor in the flyback drains it within 15 to 20 minutes, but ya never know.

OK, I'm doing this tonight if all goes well.....any other things I should be aware of inside these monitors in terms of parts which may snap, etc?
