DA15F to VGA to DVI adapter?

[TheMacGuy]

My Q605 came in today, and much to my disappointment, the casing's tabs for EVERYTHING broke off during shipping. Power supply is lose, HDD, Floppy, MoBo, everything!

But is the miraculous thing...

THE DAMN THING STILL BOOTS!!!

I have no way to test it, as I don't have a DA15F monitor. I was reading that DA15F will only connect via an adapter to VGA monitors. My question is, if I get a DA15F to VGA adapter, then a VGA to DVI adapter, will it connect to my DVI to ADC adapter to my 15" ADC Studio Display?

Its a little hard to follow, but heres what I want to do:

Q605 (DA15F connector) > VGA > DVI > ADC.

I dont know one way or another but if that dongle train actually works, I'll be impressed.

Will the LCD sync at ancient, fixed resolution, Macintosh refresh rates?

I doubt it - the VGA -> DVI adapters I've seen are for connecting a VGA display to a DVI-I port on a computer. If you take a look at the DVI plug you'll see that it likely won't have anywhere near the same number of pins as a normal DVI connector. Furthermore, it will likely have no electronics in it to convert between VGA and DVI - the adapter works by forcing the video card to run the port in VGA mode. I could be wrong, but I have never, ever seen an adapter that actually converts VGA signals into DVI.

Your best bet, if you can't get an old Mac monitor, would be to get a DA15 -> VGA adapter, and an old 15" VGA LCD, and use that.

I'd prefer to keep the monitors to LCD, as storing a CRT display would be to cumbersome to keep and store at this point in time.

Sorry, you can't connect a VGA output to a LCD Studio Monitor via a chain of passive adapters, because the Studio Display does not recognise any analog signals, and VGA is analog.

The original line of CRT Studio Display, however, could take a VGA signal. People get confused because Apple's ADC connector has pins for the VGA signals - they are the pins that surround the earth tab. These pins have no function for LCD Studio Displays.

A standard older LCD monitor will take the analog VGA signal if you can find an adapter, or build yourself one after studying the pinouts. There are other threads on this forum about getting the adapter settings correct, because different Mac models look for particular combinations of "sense lines" to set compatible resolution and sync parameters. Also check what types of LCD monitor are compatible - they need to have a good range of sync options.

then a VGA to DVI adapter

No.

You can go to like goodwill and get a small VGA LCD for cheap and with that one adapter use it. Then you still save space, although not apple still thin and useable. I have two LCD as my old crts are just starting to have cap issues. Hate to say it but unless they work on my apple II's they are just getting to be out of my price range to mess with.

My 605 arrived the same as yours. Lots of rattling plastic bits and free floating components inside. Mine still works too, and I hooked it up via an adapter and the VGA cable at 1024x768x60Hz to a spare 17" gateway LCD display that was handy. It's lovely on that big screen.

I didn't try it with a VGA-DVI adapter and DVI cable, but there's no reason it wouldn't work on this particular monitor, because it accepts analog RGB&Sync over the DVI cable (that's what the 4 pins and spade bit over to the right of the cable's connectors are). If your monitor won't accept those analog signals, you are sadly out of luck.

PS: hook up a SCSI cable (with or without anything at the other end) and your video adapter to hold the logic board in place so it doesn't flail about when you're trying to hook up your other peripherals.

Did you order it off that going out of buissness ad on CL?

I also need to get a PRAM battery. If I flip the switch, I'll get the boot chime, but no HDD activity. If I flip the switch, wait 3 seconds for the chime, back off, back on, I'll get quite abit of HDD activity and a double chime. At least Apple was smart to use a half height AA. I need to order some to keep on hand.

Nope mine was from eBay a few months ago. I think it's just the plastic on the 605 (and 8500, sheesh!)

Yep. :-/

 

[techknight]

yea, to go to DVI you need an ADC/Scan Converter. to go from VGA/RGB to TMDS/DVI. I dont know if they make them or not, but i think they do.
