Apple //c starts drive, makes beep, black screen

Sorry if this is a silly question, but an Apple //c I recently purchased doesn't seem to boot up. It starts the drive and beeps, but there isn't any video on the screen. (The screen is connected via RF, and I've tried toggling 80/40 columns) If it helps, I'm running it on a 12v power supply. (I think the original one was 15v...) Is this machine broken, or is it human error? Wink

Apple ][ rev 0 - faded color problem

The colors on my rev 0 ][ are showing an interesting issue. Compared to the colors output by my ][+, they're a little off - greens look like yellow-greens, blues look like green-blues, purples look like light-purples. I've tried twirling the color trim control every which way but I can't get the colors to exactly match those of the ][+.

Is this a quirk of the rev 0 board or is there perhaps something else I should be looking at?

Super Serial Card Repair

Hi,

to be able to repair a super serail card, I am looking for the schematic of a this card. I already found a pdf of the whole ssc handbook on the internet, but it is very hard to read the schematic in this pdf because of the poor reslution. Is there anybody who owns the original handbook and could do a high resolution scan of the schematics page?

Thanks!

Michael

Need Help with Mountain Hardware Apple II Clock Card

I recently aquired a Mountain Hardware Apple II Clock Card. But I have no idea on how to use it exactly. What slot it goes in , any kind of keyboard commands , etc.. I need to find a site that has the original Documentation for this card , and also any disks that came with this card , that I can download. If they are in .DSK format , even better...

So if anyone can help that would be awsome.

Thanks.

Commbat on Apple II?

So what are you getting your Apple II for Christmas this year?

Santa has said yes to a SubLogic Flight Simulator and (maybe) a few user manuals from 1978.

What's on your wishlist?
